Late 80s, ran across this in austin
AUSMINIUM FOUND IN HEAVY RED-TAPE DISCOVERY

Administratium experts from around the company, while searching piles of red-tape in and around Austin, recently uncovered great quantities of Heavy Red-Tape. While there have been prior findings of Heavy Red-Tape at other red-tape sites, it only occurred in minute quantities. The quantities of Heavy Red-Tape, in and around Austin have allowed Administratium experts to isolate what they believe to be a new element that they are tentatively calling AUSMINIUM.

At this time, plant officials are preparing an official press release declaring that there is no cause for alarm and absolutely NO truth to the rumors that because of the great concentration of Heavy Red-Tape in the area that there is imminent danger of achieving critical mass and the whole area collapsing into a black hole. Plant officials are stating that there is no evidence that large quantities of Heavy Red-Tape can lead to the spontaneous formation of a black-hole. They point to the lack of any scientific studies unequivalently showing that there are any existing black-holes composed of Heavy Red-Tape. The exact properties of Heavy Red-Tape and ausminium are still under study.


... snip ...

AWD (workstation) supposedly was an IBU (independent business unit) free from standard IBM red-tape ... however, every time ran into bureaucrat ... they would (effectively) say that while AWD may be free from "other" IBM red-tape ... AWD wasn't free of their red-tape. Reference to Learson trying to counter the bureaucrats and careerists destroying Watson legacy

IMS & DB2

Refed: **, - **, - **
From: Lynn Wheeler <lynn@garlic.com>
Subject: IMS & DB2
Date: 01 Jan, 2023
Blog: Facebook
The original sql/relational implementation was system/r in the 70s (at San Jose Research on VM/145). The IMS group were claiming that System/R required twice the disk space (for the index) and lots more disk I/O (possibly 4-5 times, reading the index). The response was that (especially for any changes), IMS requires significant care&feeding with more people skills and support. This was offset in the 80s for RDBMS with significant reduction in disk $$/mbyte and increase in computer memory sizes being able to cache heaviest used indexes (overall, computer systems were getting much cheaper and IMS higher people skills/costs made it easier for RDBMS to move into this market). IBM was focused on the IMS follow-on "EAGLE" and we were able to do technology transfer to Endicott ("under the radar") for SQL/DS. Then EAGLE implodes and there was request for how fast could System/R be ported to MVS, which is eventually released as DB2, originally for "decision support" only.

At the same time starting in the early 80s, reduction in (IBM) 4300 computer costs and increase in price/performance, saw large corporations making vm/4300 orders for hundreds of systems at a time for placing out in departmental areas (sort of the leading edge of the coming distributed computing tsunami, inside IBM, side effect of departmental conference rooms becoming scarce resource as they were converted to 4300 vm/rooms). IBM then expected that 4361/4381 would continue the explosion in 4331/4341 sales, but that market started moving to workstations and large PCs. Early 90s, large corporations could have thousands of RDBMS installs.

Trivia: long ago and far away, my wife was con'ed into going to POK to be responsible for "loosely-coupled" architecture, where she did Peer-Coupled Shared Data architecture. She didn't remain long because of 1) constant battles with the communication group trying to force her to use SNA/VTAM for loosely-coupled operation and 2) little uptake, except for IMS "hot-standby" (until much later with SYSPLEX and Parallel SYSPLEX). She has story about discussions with Vern Watts on who he would ask permission to do IMS "hot-standby", Vern said "nobody" ... he would just do it and tell them when it was all done.

Of course later we were doing HA/CMP and were working with the major (non-mainframe) RDBMS vendors (Oracle, Informix, Ingres, Sybase). It had originally started out as HA/6000 for the NYTimes to move their newspaper system (ATEX) off VAX/Cluster to RS/6000 (the RDBMS vendors had VAX/Cluster support in the same source base as their non-mainframe implementation, so I did some tweaks to support VAX/Cluster API semantics). I then rename it HA/CMP (High Availability Cluster Multi-Processing) when start doing technical cluster scale-up with the national labs and commercial cluster scale-up with the RDBMS vendors. Old archive post with reference to Jan92 cluster scale-up meeting with Oracle CEO (16processor by mid92, 128processor by ye92)
http://www.garlic.com/~lynn/95.html#13

and then possibly within hrs of this (archived) FSD HA/CMP email
http://www.garlic.com/~lynn/2014d.html#email920129
and (archived) email about NII meeting at LLNL (national lab)
http://www.garlic.com/~lynn/2006x.html#email920129

cluster scale-up is transferred, announced as IBM supercomputer (for technical/scientific *ONLY*) and we were told we couldn't work on anything with more than four processors (we leave IBM a few months later). Contributing was DB2 group complaining that if we were allowed to proceed it would be at least five years ahead of them.

big and little, Can BCD and binary multipliers share circuitry?

jgd@cix.co.uk (John Dallman) writes:
As best I recall, the OS had a trick to make them seem more responsive. Terminals were on serial lines, and the transceiver on the computer end would interrupt the CPU when there were still a few characters left in the output buffer. That let the OS schedule the relevant task and get it to start feeding more characters before the buffer emptied. This avoided pauses, which improved perceived performance.

Univ. had been sold 360/67 for TSS/360 to replace 709/1401 combo. I had taking fortran/computer intro class and end of semester was hired to port 1401 MPIO to 360/30 (which had replaced 1401 pending delivery of 360/67). The datacenter was shutdown for weekends and I got to have the whole place to myself for 48hrs (I could have trouble with monday morning class after 48hrs w/o sleep). After 360/67 arrived, I was hired fulltime responsible for OS/360 (360/67 running as 360/65 since TSS/360 never really came to production fruition).

Late 60s, science scenter installed CP67/CMS at the univ (3rd installation after the scince center itself and lincoln labs). I got to rewrite lots of CP67&CMS code. CP67 arrived with automagic terminal type recog. for 2741 & 1052 support ... but univ had some number of TTY terminals ... so I added ASCII/TTY support (integrated with auto terminal type recog).

I then wanted to do do single dial-in number for all terminal types
https://en.wikipedia.org/wiki/Line_hunting

however, the 360 terminal controller support dynamic changing the terminal type port scanner ... it had hardwired the port line speed. this prompted univ. to start clone controller project. We built 360 channel interface board for an Interdata/3 programmed to emulate a 360 terminal controller with the addition for being able to dynamically recognize terminal line-speed. This was upgraded to Interdata/4 for the channel interface and cluster of Interdata/3s for the port scanners. (Interdata and later Perkin/Elmer sold this as clone controller).

More than decade later was using 3277(&3272 controller) terminals which had .086 hardware response ... when there were various papers about increased productivity with quarter second response. I had enhanced VM/370 and had .11 system response (when comparable VM370 & workload systems were proudly claiming .25 system response). I pointed out that .086 hardware response combined with .25 system response was .336sec human response (didn't meet the quarter second response).

Then company introduced 3278(&3274 controller) with lots of electronics moved from 3278 terminal to 3274 controller reducing 3278 manufacturing costs. However it greatly increased coax cable protocol chatter and latency ... driving hardware response to .5sec. Writing complaints to 3278 product administrator got response that 3278 was targeted at interactive computing ... but data entry (aka electronic keypunch). It wasn't noticed by the MVS/TSO community since they rarely saw even one second system response.

trivia: late 70s, there was something analogous for disk response. As disks got faster, "I/O redrive" latency increasingly became larger part (idle from end of I/O operation interrupt to starting the next I/O). The 3880 disk controller was replacing 3830 disk controller. While 3880 increased data transfer support to 3mbyte/sec, the controller CPU was significantly slower (than 3830) ... the controller I/O command processing startup and ending took much longer (older 3330 disk with 3830 had higher throughput than with 3880 controller). They tried a gimmick where then would reflect end-of-IO interrupt when data transfer ended but before command processing was actually finished (assuming that the controller could finish command termination processing overlapped with system interrupt and device driver redrive processing).

I had been con'ed into spending part of my time playing disk engineer and had to show them all the problems that caused (in part because I had rewritten the OS I/O subsystem for them to be bullet proof and never fail so they could do ondemand, concurrent prototype testing, instead of prescheduled stand-alone testing; they then got in the habit of blaming me for prototype testing problems ... so I had to spend increasing amount of time diagnosing their hardware issues).

other old archived post on disk performance & system throughput
http://www.garlic.com/~lynn/2008c.html#88 CPU time differences for the same job

As disks got faster, (operating system) "I/O redrive" latency increasingly became larger part (idle from end of I/O operation interrupt to starting the next queued I/O). The 3880 disk controller was replacing 3830 disk controller. While 3880 increased data transfer support to 3mbyte/sec, the controller CPU was significantly slower (than 3830) ... the controller I/O command processing startup and ending took much longer (older 3330 disk with 3830 had higher throughput than with 3880 controller). They tried a gimmick where then would reflect end-of-IO interrupt when data transfer ended but before command processing was actually finished (assuming that the controller could finish command termination processing overlapped with system interrupt and device driver redrive handling).

I've mentioned several times that in the morph from CP67->VM370, they dropped and/or simplified a lot of features (including my dynamic adaptive resource management from undergraduate days and SMP, tightly-coupled multiprocessor support). One of my hobbies after joining IBM was enhanced production operating systems for internal datacenters and I spent much of 1974 and 1975 adding CP67 stuff back into VM370 (for "CSC/VM"). One of the things I didn't get around to adding back in was CP67 "CHFREE" which was located in I/O interrupt handling path ... that as soon as necessary interrupt handling stuff was finished (like was there a unit check error), invoke I/O redrive (a couple hundred instructions to redrive instead of a couple thousand). For the disk engineering input/output supervisor rewrite (making it bullet proof and never fail), so they could do development/prototype ondemand, concurrent testing (instead of scheduled, stand-alone testing), I put CHFREE back in (not so much for disk engineering, but for production operation systems, had transferred to SJR and CSC/VM became SJR/VM for internal distribution).

I've claimed that major motivation for adding SSCH in 370/XA ... was the enormous MVS redrive latency ... and they could put pending queued requests (for asynchronous redrive) down into the "hardware".

I've told the story that trout/3090 had initially configured number of channels to achieve target aggregate system throughput (based on assumption 3830->3880 just improved transfer rate to 3mbyte/sec). While 3880 tweaks somewhat masked the significantly slower 3880 processor ... the total channel busy was significantly worse than a their assumption about 3880 being a 3830 with support for (3380) 3mbyte/sec transfer rate. When they realized how bad the 3880 channel busy was going to be, they realized they would have to significantly increase the number of channels (to achieve desired system throughput). The increase in number of channels then required an additional TCM, there was joke that 3090 was going to bill the 3880 group for the increase in 3090 manufacturing cost. IBM marketing eventually respun the increase in number of 3090 channels for the 3090 making it a wonderful I/O machine (rather than counter to the significant increase for 3880 controller channel busy overhead).

This is also analogous to the early 70s decision to make all 370s virtual memory. Basically MVT storage management was so bad that region execution sizes had to be specified four times larger than actually used. As a result a typical 1mbyte, 370/165 would only run four concurrently executing regions ... insufficient to keep machine busy and justified. Remapping MVT into 16mbyte virtual memory would allow increasing the number of concurrently executing regions by factor of four times with little or no paging.

From: Lynn Wheeler <lynn@garlic.com>
Subject: 1403 printer
Date: 02 Jan, 2023
Blog: Facebook
Took two credit hr intro to fortran/computers and at end of semester got student job to reimplement 1401 MPIO on 360/30. The univ. had been sold 360/67 for TSS/360 replacing 709/1401 (709 tape->tape, 1401 unit record front end) ... and the 1401 was temporarily replaced with 360/30 (pending availability of 360/67). 360/30 had 1401 emulation so could continue to run 1401 MPIO ... but I guess they wanted to get 360 experience. The univ. shutdown the datacenter over the weekend and they let me have the whole place to myself (for weekends, although 48hrs w/o sleep could make monday morning classes difficult). I was given a bunch of hardware and software manuals and got to design my own monitor, interrupt handlers, device drivers (console, tape, 2540 reader/punch 1403), error recovery, storage management, etc. Within a few weeks had 2000 card 360 assembler program. Univ. had both 1403 and 1403N1.
https://en.wikipedia.org/wiki/IBM_1403

I quickly learned that 1st thing coming in was to clean tape drives, 1403s, take 2540 apart and clean it, etc. Also, sometimes Fri 3rd shift finished early and had powered everything off. Sometimes powering on 360/30 ... it wouldn't come up and had to figure out putting all controllers in CE mode, power on 360/30, individually power on all controllers (and then take them out of CE mode). Within year of taking intro class, I was hired fulltime responsible for OS/360 (after 360/67 came in, TSS/360 never came to production fruition so ran as 360/65 with OS/360). Then before I graduate, I'm hired fulltime into small group in Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing into independent business unit to better monetize the investment, including offering services to non-Boeing entities).

After graduating, I leave Boeing and joined IBM cambridge science center. CSC had modified 360/40 with virtual memory hardware and developed CP40/CMS, which morphs into CP67/CMS when 360/67 becomes available (later morphs into VM370/CMS)

Some of the MIT CTSS/7094 people had gone to the 5th flr for MULTICS. Others had gone to the science center on the 4th flr. Some amount of CMS carried over from CTSS. CTSS runoff
https://en.wikipedia.org/wiki/TYPSET_and_RUNOFF
was redone for CMS as "SCRIPT" ... GML was also invented at the science center in 1969 and GML tag processing was added to CMS SCRIPT.

One of the first mainstream IBM manuals done in CMS SCRIPT was 370 Architecture Manual (called "red book" for distribution in red 3-ring binder). CMS SCRIPT command option would print either the full architecture manual or the 370 Principles of Operation subset. 1403/3211 printed POO (usually) can be seen by non-proportional font. Later versions might be printed on 3800 (or other laser printer) with proportional font. However, I was a little surprised to see Mar1983 Principles Of Operation (with non-proportional font).

re:
http://www.garlic.com/~lynn/2023.html#4 Mainrame Channel Redrive

I've commented that original 360 CKD ... and "multi-track search", traded off abundant I/O capacity for relatively constrained processor and real memory ... however by the mid-70s that trade-off was beginning to invert. In the early 80s, I had written a tome that disk "relative system throughput" had declined by an order of magnitude (factor of ten times) since the 60s ... aka disk throughput had increased 3-5 times while processor speed and real storage size had increased by 40-50 times. A GPD (disk division) took exception and assigned the division performance group to refute my claim. After a couple week, they basically said that I had slightly understated the problem. They then respun the analysis for a (mainframe user group) SHARE presentation on configuring disks for improved system throughput (SHARE 63, B874, 16Aug1984).

Leopards Eat Kevin McCarthy's Face
https://www.nytimes.com/2023/01/04/opinion/kevin-mccarthy-speaker-race.html
Kevin McCarthy nurtured the spirit of reactionary nihilism in the Republican Party, first by trying to harness the energy of the Tea Party for his own ambition, and then by his near-total capitulation to Donald Trump. Now the chaotic forces he abetted have, at least for the moment, derailed his goal of becoming House speaker, subjecting him to multiple public humiliations at what was supposed to be his moment of triumph.

Ponzi Hospitals and Counterfeit Capitalism. The end of cheap money in our monopoly-heavy economy is going to make things very weird. Big private equity shops could be in trouble.
https://mattstoller.substack.com/p/ponzi-hospitals-and-counterfeit-capitalism

... from nakedcaoitalism.com: If private equity is pulling as much cash as it can out of hospitals, then Hospital Infection Control administrators will respond to that. Hence, cheap masks or no masks, no HEPA, no ventilation improvements beyond existing isolation wards, etc., and a captured CDC writing its guidance to accommodate them. Paradigm shifts cost money, even beyond the cost ot careers!

... past couple months there has been lots of divers doing repair work on the seawall on the perimeter of the naval academy ... workers say that the concrete has significant erosion.

The most common blend of modern concrete, known as Portland cement, a formulation in use for nearly 200 years, can't come close to matching that track record, says Marie Jackson, a research engineer at the University of California at Berkeley who was part of the Roman concrete research team. "The maritime environment, in particular, is not good for Portland concrete. In seawater, it has a service life of less than 50 years. After that, it begins to erode," Jackson says.

Karl Rove, a major player in the Bush/Cheney administration, summed up this hubris in this--now-infamous passage: "We're an empire now, and when we act, we create our own reality. And while you're studying that reality -- judiciously, as you will -- we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors . . . and you, all of you, will be left to just study what we do."

Related to the idea of history being un-American is the business- and management-oriented nature of the officer corps in the U.S. military. To be promoted to field-grade (major or lieutenant commander), you almost have to have a master's degree or be close to finishing one. But rarely do officers choose to pursue a master's in history or any other subject related to the humanities. The master's of choice is in business administration or some type of management.

By pursuing MBAs and management degrees, officers show their practical nature.

I was introduced to John Boyd in the early 80s and would sponsor his briefings. He would comment that former military officers, steeped in rigid, top-down command and control were beginning to contaminate US corporate culture. Originated for WW2 where US had to deploy millions and had to rely on very few with military experience, observing that US required 11% officers (growing to 20%) while the Germans had 3% (or less). However about the same time, there started to appear articles that MBAs were starting to destroy US corporations (with their myopic focus on short term results). Longer discussion

The World Crisis, Vol. 1, Churchill explains the mess in middle east started with move from 13.5in to 15in Naval guns (leading to moving from coal to oil)

loc2012-14:
From the beginning there appeared a ship carrying ten 15-inch guns, and therefore at least 600 feet long with room inside her for engines which would drive her 21 knots and capacity to carry armour which on the armoured belt, the turrets and the conning tower would reach the thickness unprecedented in the British Service of 13 inches.

loc2087-89:
To build any large additional number of oil-burning ships meant basing our naval supremacy upon oil. But oil was not found in appreciable quantities in our islands. If we required it, we must carry it by sea in peace or war from distant countries.

loc2151-56:
This led to enormous expense and to tremendous opposition on the Naval Estimates. Yet it was absolutely impossible to turn back. We could only fight our way forward, and finally we found our way to the Anglo-Persian Oil agreement and contract, which for an initial investment of two millions of public money (subsequently increased to five millions) has not only secured to the Navy a very substantial proportion of its oil supply, but has led to the acquisition by the Government of a controlling share in oil properties and interests which are at present valued at scores of millions sterling, and also to very considerable economies, which are still continuing, in the purchase price of Admiralty oil.

Iran people eventually revolt against the horribly oppressive, (US backed) autocratic government.

CIA Director Colby wouldn't approve the "Team B" analysis (exaggerated USSR military capability) and Rumsfeld got Colby replaced with Bush, who would approve "Team B" analysis (justifying huge DOD spending increase), after Rumsfeld replaces Colby, he resigns as white house chief of staff to become SECDEF (and is replaced by his assistant Cheney)

Then in the 80s, former CIA director H.W. is VP, he and Rumsfeld are involved in supporting Iraq in the Iran/Iraq war

In the early 90s, H.W. is president and Cheney is SECDEF. Sat. photo recon analyst told white house that Saddam was marshaling forces to invade Kuwait. White house said that Saddam would do no such thing and proceeded to discredit the analyst. Later the analyst informed the white house that Saddam was marshaling forces to invade Saudi Arabia, now the white house has to choose between Saddam and the Saudis.

... roll forward ... Bush2 is president and presides over the huge cut in taxes, huge increase in spending, explosion in debt, the economic mess (70 times larger than his father's S&L crisis) and the forever wars, Cheney is VP, Rumsfeld is SECDEF and one of the Team B members is deputy SECDEF (and major architect of Iraq policy).
https://en.wikipedia.org/wiki/Paul_Wolfowitz

Before the Iraq invasion, the cousin of white house chief of staff Card ... was dealing with the Iraqis at the UN and was given evidence that WMDs (tracing back to US in the Iran/Iraq war) had been decommissioned. the cousin shared it with (cousin, white house chief of staff) Card and others ... then is locked up in military hospital, book was published in 2010 (4yrs before decommissioned WMDs were declassified)

NY Times series from 2014, the decommission WMDs (tracing back to US from Iran/Iraq war), had been found early in the invasion, but the information was classified for a decade
http://www.nytimes.com/interactive/2014/10/14/world/middleeast/us-casualties-of-iraq-chemical-weapons.html

note the military-industrial complex had wanted a war so badly that corporate reps were telling former eastern block countries that if they voted for IRAQ2 invasion in the UN, they would get membership in NATO and (directed appropriation) USAID (can *ONLY* be used for purchase of modern US arms, aka additional congressional gifts to MIC complex not in DOD budget). From the law of unintended consequences, the invaders were told to bypass ammo dumps looking for WMDs, when they got around to going back, over a million metric tons had evaporated (showing up later in IEDs)

There was also a calculated decision to use the Saudis as surrogates in the cold war. The United States actually encouraged Saudi efforts to spread the extremist Wahhabi form of Islam as a way of stirring up large Muslim communities in Soviet-controlled countries. (It didn't hurt that Muslim Soviet Asia contained what were believed to be the world's largest undeveloped reserves of oil.)

Ayatollah Khomeini's revolutionary regime took hold in Iran by ousting the Shah and swearing hostility against the United States.

IBM Loses Top Patent Spot After Decades as Leader

Why IBM is no longer interested in breaking patent records-and how it plans to measure innovation in the age of open source and quantum computing
https://fortune.com/2023/01/06/ibm-patent-record-how-to-measure-innovation-open-source-quantum-computing-tech/

I wondered what was cause and what was effect, if it shifted because it lost top spot or if it lost top part because it shifted?

IBM Loses Top Patent Spot After Decades as Leader
https://www.bloomberg.com/news/articles/2023-01-06/ibm-loses-top-patent-spot-after-decades-as-ip-leader

I first saw the IBM article about shifting strategy from top spots in patents and conjectured that was publicity spin that they had lost top spot in patents because they no longer spent the money (and purposeful strategy sounded better), i.e. money going to stock buybacks and dividends).

IBM Marketing, Sales, Branch Offices

Refed: **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **

As undergraduate, within a year of taking 2credit hr intro to fortran/computers, univ. hires me fulltime responsible for os/360, then before I graduate, I'm hired fulltime into small group in Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing in an independent business unit to better monetize the investment, including offering services to non-Boeing entities). I thot Renton datacenter was possibly largest in the world, couple hundred million in 360s stuff ... 360/65s arriving faster than they could be installed, boxes constantly being staged in the hallways around the machine room. Both Boeing people and IBM account team tell story about 360 announcement day ... Boeing walks into the marketing rep (who hardly knows what 360 is) and places a large 360 order ... this was in days of straight commission ... claimed that it made the marketing rep highest paid IBMer that year. The following year, IBM transitions from commission to quota. Jan, Boeing makes another large order ... making the rep's quota for the year. His quota then gets "adjusted" ... he leaves IBM shortly later.

In the early 80s, I'm introduced to John Boyd and sponsored his briefings at IBM. His biographies mention that he was put in command of "spook base" (about the same time I was at Boeing) which was a $2.5B windfall for IBM (ten times Boeing). Some of IBM account there
https://www.amazon.com/When-Big-Blue-Went-War-ebook/dp/B07923TFH5/

After I graduated, I joined the IBM Cambridge Science Center (instead of staying at Boeing). One of my hobbies was enhanced production operating systems for internal datacenters (including online sales&marketing support HONE systems were long time customer) ... I also got to attend user group meetings and drop in on customers. Data center manager for one of the largest financial industry IBM accounts, use to like me to drop in and talk technology. Long winded account including the branch manager horribly offending the customer and in retribution they were ordering an Amdahl machine (first for true-blue commercial account, up until then Amdahl had only sold into technical/scientific/univ market), I was suppose to help obfuscate the reason for the Amdahl order by going onsite for a year ... more details in this long winded account
https://www.linkedin.com/pulse/john-boyd-ibm-wild-ducks-lynn-wheeler/

In 1975, somehow AT&T longlines was allowed to get a copy of one of my internal VM370 systems. Note in the morph from CP67->VM370, a lot of features were dropped (including tightly coupled multiprocessor support) and/or greatly simplified. I spent much of 1974 upgrading VM370 with CP67 enhancements and somehow AT&T acquired one of those systems. This was before I had reimplemented multiprocessor support, originally for the US HONE complex (online sales&marketing support HONE was longtime customer, predating VM370 days). In the early 80s, the AT&T IBM account rep tracks me down at San Jose Research wanting help with AT&T and my 1975 VM370 system. Turns out they had propagated my internal VM370 system around AT&T ... moving to the latest 370 models. However in the early 80s, the next new IBM machine was 3081 which was multiprocessor only and IBM was afraid that AT&T (as well as ACP/TPF market, ACP/TPF at the time didn't have multiprocessor support) would all move to Amdahl (which had single processor machine about the same performance as two-processor 3081K).

NCSS and Dun & Bradstreet

Blog: Facebook
D&B trivia; one of the CP67 spinoffs of the IBM Cambridge Science Center in the 60s was NCSS ... which is later bought by Dun & Bradstreet
https://en.wikipedia.org/wiki/National_CSS
above mentions
https://en.wikipedia.org/wiki/Nomad_software

even before SQL (& RDBMS) originally done on VM370/CMS (aka System/R at IBM SJR, later tech transfer to Endicott for SQL/DS and to STL for DB2) there were other "4th Generation Languages", one of the original 4th generation languages, Mathematica made available through NCSS (cp67/cms online precursor to vm37/cms)
http://www.decosta.com/Nomad/tales/history.html
One could say PRINT ACROSS MONTH SUM SALES BY DIVISION and receive a report that would have taken many hundreds of lines of Cobol to produce. The product grew in capability and in revenue, both to NCSS and to Mathematica, who enjoyed increasing royalty payments from the sizable customer base. FOCUS from Information Builders, Inc (IBI), did even better, with revenue approaching a reported $150M per year. RAMIS moved among several owners, ending at Computer Associates in 1990, and has had little limelight since. NOMAD's owners, Thomson, continue to market the language from Aonix, Inc. While the three continue to deliver 10-to-1 coding improvements over the 3GL alternatives of Fortran, Cobol, or PL/1, the movements to object orientation and outsourcing have stagnated acceptance.

Information Builders's FOCUS product began as an alternate product to Mathematica's RAMIS, the first Fourth-generation programming language (4GL).

... and perhaps most damaging, the old culture under Watson Snr and Jr of free and vigorous debate was replaced with *SYNCOPHANCY* and *MAKE NO WAVES* under Opel and Akers. It's claimed that thereafter, IBM lived in the shadow of defeat ... But because of the heavy investment of face by the top management, F/S took years to kill, although its wrong headedness was obvious from the very outset. "For the first time, during F/S, outspoken criticism became politically dangerous," recalls a former top executive.

one of the IBMers that was in SE Asia (out of the Hawaii office) has commented (in this group) in the past that they did get to go to 100% club ... but weren't singled out as the #1 that year ... significant more than the ones were singled out ... conjecture was that IBM didn't want to highlight how much earnings was coming from that office.

How Wall Street Created a Nation: J.P. Morgan, Teddy Roosevelt, and the Panama Canal
http://www.amazon.com/How-Wall-Street-Created-Nation-ebook/dp/B00MDW60IY/
loc3367-70:
After Panama, Cromwell spent the better part of his time in France. He received the Grand Cross of the Legion of Honor from that country for his work in resurrecting the Panama Canal. Meanwhile, his firm, Sullivan & Cromwell, flourished as one of Wall Street's preeminent law firms under the direction of his handpicked successors, John Foster Dulles and Arthur H. Dean. Cromwell died in 1948 at the age of ninety-four, leaving nineteen million dollars and no heirs.

... snip ...

Gangsters of Capitalism
https://www.amazon.com/Gangsters-Capitalism-Smedley-Breaking-Americas-ebook/dp/B092T8KT1N/
Smedley Butler was the most celebrated warfighter of his time. Bestselling books were written about him. Hollywood adored him. Wherever the flag went, "The Fighting Quaker" went--serving in nearly every major overseas conflict from the Spanish War of 1898 until the eve of World War II. From his first days as a 16-year-old recruit at the newly seized Guantanamo Bay, he blazed a path for empire: helping annex the Philippines and the land for the Panama Canal, leading troops in China (twice), and helping invade and occupy Nicaragua, Puerto Rico, Haiti, Mexico, and more. Yet in retirement, Butler turned into a warrior against war, imperialism, and big business, declaring: "I was a racketeer for capitalism."

Treason in America from Aaron Burr to Averell Harriman
https://www.amazon.com/Treason-America-Aaron-Averell-Harriman-ebook/dp/B005VHDR1G/
loc6565-69:
Cromwell's "French" company was paid $40 million by the United States. Colombia was paid nothing. Teddy Roosevelt refused ever to disclose just who it was who got the $40 million, though it was known that William Nelson Cromwell received a fee of at least $600,000. Cromwell later hired a young lawyer named John Foster Dulles into his firm; Dulles would become Sullivan and Cromwell's boss, and lead the firm into its position as chief legal representative for Adolf Hitler and the international cartels of the German Nazis.

John Foster Dulles played major role rebuilding Germany economy, industry, military from the 20s up through the early 40s
https://www.amazon.com/Brothers-Foster-Dulles-Allen-Secret-ebook/dp/B00BY5QX1K/
loc905-7:
Foster was stunned by his brother's suggestion that Sullivan & Cromwell quit Germany. Many of his clients with interests there, including not just banks but corporations like Standard Oil and General Electric, wished Sullivan & Cromwell to remain active regardless of political conditions.

loc938-40:
At least one other senior partner at Sullivan & Cromwell, Eustace Seligman, was equally disturbed. In October 1939, six weeks after the Nazi invasion of Poland, he took the extraordinary step of sending Foster a formal memorandum disavowing what his old friend was saying about Nazism

... snip ...

June1940, Germany had a victory celebration at the NYC Waldorf-Astoria with major industrialists. Lots of them were there to hear how to do business with the Nazis
https://www.amazon.com/Man-Called-Intrepid-Incredible-Narrative-ebook/dp/B00V9QVE5O/

somewhat replay of the Nazi celebration, after the war, 5000 industrialists and corporations from across the US had conference (also) at the Waldorf-Astoria, and in part because they had gotten such a bad reputation for the depression and supporting Nazis, as part of attempting to refurbish their horribly corrupt and venal image, they approved a major propaganda campaign to equate Capitalism with Christianity.
https://www.amazon.com/One-Nation-Under-God-Corporate-ebook/dp/B00PWX7R56/

part of the result by the 50s was adding "under god" to the pledge of allegiance (and the US motto, "In God We Trust"). slightly cleaned up version
https://en.wikipedia.org/wiki/Pledge_of_Allegiance
Even though the movement behind inserting "under God" into the pledge might have been initiated by a private religious fraternity and even though references to God appear in previous versions of the pledge, historian Kevin M. Kruse asserts that this movement was an effort by corporate America to instill in the minds of the people that capitalism and free enterprise were heavenly blessed. Kruse acknowledges the insertion of the phrase was influenced by the push-back against Russian atheistic communism during the Cold War, but argues the longer arc of history shows the conflation of Christianity and capitalism as a challenge to the New Deal played the larger role.[28]

If the threats of the economic hit men don't persuade, the "jackals" will come in to make good on them. The jackals, says Perkins, are the CIA-sanctioned heavy mob who foment coups and revolutions, murder, abduction and assassination. And when the jackals fail, as was the case in Iraq, then the military goes in.

If you are unfamiliar with this fiasco, which was also the true proximate cause of Larry Summers' ouster from Harvard, you must read an extraordinary expose, How Harvard Lost Russia, from Institutional Investor. I am told copies of this article were stuffed in every Harvard faculty member's inbox the day Summers got a vote of no confidence and resigned shortly thereafter.

How Harvard lost Russia; The best and brightest of America's premier university came to Moscow in the 1990s to teach Russians how to be capitalists. This is the inside story of how their efforts led to scandal and disgrace (gone 404, but lives on at wayback machine)
https://web.archive.org/web/20130211131020/http://www.institutionalinvestor.com/Article/1020662/How-Harvard-lost-Russia.html
Mostly, they hurt Russia and its hopes of establishing a lasting framework for a stable Western-style capitalism, as Summers himself acknowledged when he testified under oath in the U.S. lawsuit in Cambridge in 2002. "The project was of enormous value," said Summers, who by then had been installed as the president of Harvard. "Its cessation was damaging to Russian economic reform and to the U.S.-Russian relationship."

PROFS trivia

Refed: **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **

Subject: PROFS trivia
Date: 11 Jan, 2023
Blog: Facebook
PROFS trivia ... the PROFS group was collecting internal apps and wrapping menus around them for (the mostly computer illiterate) users. They acquired a very early version of VMSG for the email client. When the VMSG author tried to offer them a much enhanced version, they tried to get him fired (folklore is that they had already taken credit for it). The whole thing quiets down with the VMSG author demonstrates that his initials are in every PROFS note (in non-displayed field). After that, the VMSG author only shares his source with me and one other person. While PROFS might delete client copies ... they were on the server's backup tapes. Later administrations became more savy about server backup copies.

Late 70s, Some of us at SJR in friday after work sessions had lots of discussions about what to do about the mostly computer illiterate employees, managers, executives, etc. This was at a time when 3720 terminals were part of the annual budget process and required VP sign-off (even after we showed the 3yr depreciation was about the same monthly "cost" as a desk phone). Then there was a rapidly spreading rumor that members of the corporate executive committee were communicating via email and result was large numbers of (computer illiterate) managers were pre-empting 3270 terminal deliveries for their desks. They would be powered on in the morning ... being unused all day while the PROFS menu was burned into the screen (and any management email was actually handled by staff). More than decade later there were still managers that rerouted large screen PS2/486s to their desks for 3270 terminal emulation (status symbol and fabricated appearance of computer illiteracy, spending the days unused with the same PROFS menu burned into the screen).

after 4300s were announced, but before shipped ... I got con'ed into doing benchmarks for national lab on engineer 4341 I was running in bldg15 (for dasd product test) ... they were looking at getting 70 for compute farm (sort of the leading edge of coming cluster supercomputing tsunami). small cluster of 4341s had much higher processing than 3033, significantly cheaper, as well as much less floor space, power, and cooling. At one point head of POK apparently felt so threaten that he convinces corporate that the allocation for critical 4341 manufacturing component should be cut in half. Then started to see large corporations making orders for hundreds of vm/4300s at a time for placing out in departmental areas (sort of the leading edge of the coming distributed computing tsunami, inside IBM, conference rooms were in short supply with so many turning into departmental vm370 rooms).

MVS then wanted to play in that market ... first the only new mid-range DASD for install in non-datacenter, was 3370 FBA (and MVS didn't have FBA support). Eventually CKD simulation was added to 3370 for MVS's benefit as "3375". However, it didn't do MVS much good, the distributed departmental market was looking for large tens of vm/4300s systems per support person ... while MVS still required multiple persons per system.

Trivia: I had been con'ed into helping Endicott with the VM microcode assist for 138/148 (precursor to, and assist also used in, 4331/4341) and then running around the world presenting details to business planners&forecaster. Endicott tried to convince corporate to allow pre-installed VM shipped in every machine (sort of like PR/SM-LPAR more than decade later).

some 360/370 microcode posts
http://www.garlic.com/~lynn/submain.html#360mcode

However, head of POK had only recently managed to convince corporate to kill the VM/370 product, shutdown the VM/370 development group and transfer all the people to POK (claiming otherwise MVS/XA wouldn't be able to ship on time). Endicott eventually manages to save the VM/370 product misson (but wasn't allowed to ship VM370 preinstalled on every machine) ... Endicott does have to recreate a VM370 development group from scratch (some amount of customer quality complaints during this period). Other trivia: POK wasn't going to tell the VM/370 people they had to move to POK until the very last minute, to minimize the number that might escape ... however it leaked and numerous escaped into the Boston area (this was about the infancy of DEC VMS and joke was head of POK was a major contributor to DEC VMS). There was then a witchhunt for the source of the leak, fortunately for me, nobody gave up the source. my tome on bureaucrats, careerists and MBAs destroying IBM and the Watson legacy.

Note: 23Jan1969 unbundling announcement, IBM started to charge for software, maint., SE services, etc. Previously part of SE training was sort of apprentice program as part of large group onsite at customer. After unbundling announce, IBM couldn't figure out how not to charge for trainee SEs onsite at the customer (large SE group constantly onsite at customer, disrupting IBM's traditional account control, also disrupted critical part of training of new generations of SEs). To address part of the SE training, HONE (hands-on network experience) was created with branch office online access to CP67 datacenters for practice running guest operating systems. When 370 initially announced, the HONE CP67 systems were enhanced with simulation for the new 370 instructions ... allowing branch office running 370 guest operating systems.

One of my hobbies after joining IBM was enhanced production systems for internal datacenters and HONE was long time customer. The cambridge science center had also ported APL\360 to CMS for CMS\APL ... fixing its memory management for large virtual memory workspaces (APL\360 traditionally was 16kbyte workspaces) for demand page environment and added APIs for system services (like file i/o, enabling lots of real world applications). HONE then started offering online APL-based sales&marketing tools ... which then came to dominate all HONE activity ... and SE training with guest operating systems just dwindled away (with SE skill level dropping ... increasingly become phone directory for internal IBM technical contacts). some discussion in controlling market post

Previous was various, long term, systemic, strategic ... nearer (to the 13 "baby blues" reorg in preparation to breaking up the company), tactical I've frequently posted is about the communication group's stanglehold on mainframe datacenters. In this recent (Facebook) post/thread on IBM Profs, I have reply about vm/4300s leading edge to the coming distributed computing tsunami
http://www.garlic.com/~lynn/2023.html#18 PROFS trivia

3270 dumb terminal emulation helped give it early market penetration ... but as distributed computing (and client/server) evolved, communication group strategic ownership of everything that crossed datacenter walls and fiercely fighting off distributed computing and client/server gave them death grip on mainframe datacenters.

Late 80s, senior disk engineer got talk scheduled at internal, world-wide, annual communication group conference supposedly on 3174 performance, but opened the talked with statement that the communication group would be responsible for the demise of the disk division. Scenario was that communication group had stranglehold on mainframe datacenters with their corporate strategic ownership of everything that crossed datacenter walls (and were fiercely fighting off distributed computing and client/server). The disk division was seeing data fleeing mainframe datacenters to more distributed computing friendly platforms, with drop in disk sales. The disk division had come up with a number of solutions, but they were constantly being vetoed by the communication group.

GPD/Adstar VP partial countermeasure (to communication group death grip) was investing in distributed computing startups that would use IBM disks. He would have us in periodically to discuss his investments and asked us if we could drop by and provide any assistance. One was "MESA Archival" in Boulder ... spinoff startup of NCAR
https://en.wikipedia.org/wiki/National_Center_for_Atmospheric_Research
https://ncar.ucar.edu/

another communication group death grip story about severely performance kneecapping microchannel cards as part of their fierce battle fighting off distributed computing and client/server; AWD (workstation division) had PC/RT with AT-bus and had done their own 4mbit token-ring card. Then for the RS/6000 with microchannel, were told they could only use PS2 microchannel cards. One of the examples was the PS2 16mbit token-ring had lower card throughput than the PC/RT 4mbit token-ring card (i.e. a PC/RT 4mbit token-ring server would have higher throughput than RS/6000 16mbit token-ring server). Joke was that RS/6000 limited to the severely performance kneecapped PS2 microchannel cards wouldn't have better throughput than PS2/486 (token-ring, display, disks, etc).

Subject: IBM Punch Cards
Date: 13 Jan, 2023
Blog: Facebook
I took two credit hour intro to fortran/computers and at the end of the semester was hired as student programmer to re-implement 1401 MPIO on 360/30. The univ had 709/1401 (709 tape->tape with 1401 was unit record front end). They had been sold a 360/67 for TSS/360 replacing the 709/1401 ... temporarily pending arrival 360/67, the 1401 was replaced with 360/30. The 360/30 had 1401 emulation and they could have continued to run 1401 MPIO (tape->printer/punch & card reader->tape), but I guess they wanted to get 360 experience. I was given a whole bunch of manuals and got to design & implement my own monitor, interrupt handlers, device drivers, error recovery, storage management, etc). The univ. shutdown the datacenter on weekends and I would have the whole place to myself (although 48hrs w/o sleep made monday morning classes hard). After a few weeks I had a 2000 card 360 assembler program with assembler option for running stand alone or under os/360 mode. The stand-alone version took 30mins to assemble ... the os/360 version took 60mins (each DCB macro took 5-6mins to assemble).

I quickly learned to read hex punch holes; fan the assemble output TXT deck looking for the hex displacement card needing patch ... would duplicate card in 029 out to patch area and then multi-punch hex patch into the new card. I would usually do that in much less time than it took to do a new assembly. Within a year of taking intro class, the 360/67 arrived and I was hired fulltime responsible for OS/360 (tss/360 never came to production, so ran as 360/65).

Student fortran jobs took less than second with 709 IBSYS tape->tape; initially OS/360 took over a minute for student fortran job. I installed HASP, cutting the time in half. I then started reordering cards in STAGE2 SYSGEN deck to carefully place files and PDS members to optimize disk arm seek and PDS directory lookup multi-track search, cutting another 2/3rds to 12.9secs. Student fortran jobs never got better than 709 <1sec until I installed Univ of Waterloo's WATFOR.

trivia1: PTF "fixes" replacing system PDS members would start to destroy my careful ordering and begin to result in performance degradation. Sometimes there were so many "fixes", I would be forced to do an interim system generation to restore order and performance.

trivia2: JCL was going through evolution ... had to do a lot of testing for every new OS/360 release, there was always some administration production programs where the JCL would "break".

Before I graduate, I'm hired fulltime into small group in the Boeing CFO office to help with formation of Boeing Computer Services (consolidate a couple hundred million in dataprocessing into a independent business unit to better monetize the investment, including offering services to non-Boeing entities). I thought Renton datacenter was possibly largest in the world, 360/65s were arriving faster than they could be installed, boxes constantly being staged in the hallways around the machine room. Lot of politics between director of Renton and the CFO ... who only had a 360/30 up at Boeing Field for payroll ... although they enlarge the machine room to install a 360/67 for me to play with when I'm not doing other stuff.

In the early 80s, I'm introduced to John Boyd and would sponsor his briefings at IBM. One of his stories was being very vocal about the electronics across the trail wouldn't work. Possibly as punishment he is put in command of "spook base" (about the same time I'm at Boeing) ... his biographies say "spook base" was $2.5B "windfall" for IBM (ten times Boeing).

Some of the MIT CTSS/IBM7094 people went to the 5th flr to do multics. Others went to the IBM science center on the 4th flr and did (cp40/cms & cp67/cms ... precursors to vm370/cms) virtual machines, the internal network (technology in the 80s also used for the corporate sponsored univ BITNET), performance tools, etc. Various pieces of CTSS was duplicated for CMS, including CTSS RUNOFF as SCRIPT. Then in 1969, GML was invented at the science center (name chose because first letters are the same as inventors last name) and GML tag processing was added to CMS SCRIPT (after another decade it morphs into ISO standard SGML, and after another decade morphs into HTML at CERN).

One of the first mainstream IBM documents done in SCRIPT was the 370 Architecture Manual (called "red book" for distribution in 3-ring red binder). Using CMS script options, either the full architecture manual could be printed (with engineering considerations, justifications, alternatives) or the 370 Principle of Operations subset. Usually can tell the 370 script versions because they look like they have been printed on 1403/3211 printer ... here is a more recent version from the 80s:.

for the fun of it, other topic drift ... early 80s, before REX was renamed REXX and released to customers, I wanted to show it wasn't just another pretty scripting language. I chose to redo a very large assembler-implemented application, system problem analysis and dump reader ... objective was to reimplement it in REX within three months working half time, with ten times the function *AND* ten times the performance (some slight of hand for interpreted language); turns out I finished early, so wrote a library of automated functions that searched for common failure signatures. I also included a softcopy of IBM's messages & code manual and would provide various kinds of search features.

I thot it would replace the current app shipped to customers ... but for whatever reason it didn't, even tho it was in use by nearly every internal datacenter and PSR. I eventually get permission to do presentations on how I did the implementation at various customer user group meetings, and after a few months, similar implementations started to appear.

some people from science center came out and installed CP67 (virtual machines, precursor to VM370) at the univ (3rd installation after cambridge and lincol labs) ... I mostly ran it on my weekends dedicated window and rewrote lots of the cp67 code. CP67 had 1052 & 2741 with some automagic code that determined terminal type and used the SAD CCW to dynamically assign the correct terminal line scanner to each port. The univ had a bunch of TTY/ASCII terminals and I added ASCII support ... integrated in with dynamically determining terminal type (triva: when the ASCII/TTY hardware arrived to install in the 360 terminal controller, it came in a box from Heathkit). I then wanted to use a single dialup phone number for all terminal types
https://en.wikipedia.org/wiki/Line_hunting

... however it didn't quite work ... IBM had taken shortcut and had hardwired linespeed to each port. Thus was kicked off univ. program to do clone (terminal) controller, built a channel interface card for a Interdata/3 programmed to emulate IBM controller with the addition that it did dynamic line speed recognition ... four of us get written up for (some part of) IBM clone controller market. Later it was enhanced with an Interdate/4 for channel interface and cluster of Interdata/3s for port interfaces. Interdata and then Perkin-Elmer sold them as IBM clone controller.

IBM clone controller posts

Note claims are that the 70s IBM "Future System" project (totally different than 370 and would totally replace it) motivation was to be so complex that clone makers wouldn't be able to keep up ... but then it could be said that it was so complex that IBM couldn't do it either (and the massive IBM effort imploded). Mentioned here as part of the destruction to Watson legacy

https://www.linkedin.com/pulse/ibm-breakup-lynn-wheeler/

Note that during FS, internal politics were shutting down 370 efforts ... and the claim is the lack of new 370 products gave the clone 370 system makers their market foothold (i.e. from the law of unintended consequences, in trying to address clone controller market, they enabled the clone system market)

Note SMART trivia: Dick left IBM and worked as consultant. Mainstream IBM (like hudson valley) had huge problems with the 23jun1969 unbundling that started to charge for software (and other stuff). Business rules were that revenue had to cover initial development plus ongoing enhancements and maintenance; forecasts typical did low, middle, & high price (with number of predicted licenses to see if it could meet business rules and whether there was any price elasticity) ... mainstream IBM would periodically find that there was NO price point that would meet business rules. One of the first gimmicks was JES2 NJE, it was announced as combined product with VM370 VNET/RSCS with nearly all VNET revenue subsidizing NJE. The business rules were then relaxed so that they just applied to an organization as a whole. MVS ISPF had similar problem as JES2 NJE ... so VM370 Performance Products (including SMART) was moved into the ISPF organization (at the time vm370 performance products had approx same total revenue as ISPF). They cut the VM370 performance product group to three people so nearly all of the VM370 revenue could subsidize the nearly 200 people (at the time) in the ISPF operation.

Medicare Begins to Rein In Drug Costs for Older Americans

Medicare Begins to Rein In Drug Costs for Older Americans. Reforms embedded in the Inflation Reduction Act will bring savings to seniors this year. Already some lawmakers are aiming to repeal the changes.
https://www.nytimes.com/2023/01/14/health/medicare-drug-prices.html

2002, congress lets the fiscal responsibility act lapse (spending couldn't exceed revenue, on its way to eliminating all federal dept). 2010 CBO report, 2003-2009, spending increased by $6T and tax revenue decreased by $6T for $12T difference from a fiscal responsibility budget (first time taxes was reduced to not pay for two wars, sort of confluence of Federal Reserve and Too Big To Fail needed huge federal debt, special interests wanted huge tax cut, and Military-Industrial Complex wanted huge spending increase and perpetual wars).

The first major bill after fiscal responsibility act lapsed was Medicare Part-D. CBS 60mins had segment on 18 Republicans shepherding "part-d" through, just before final vote they adding one line change precluded competitive bidding and prevented CBO from distributed report about the change. Also found within 6-12 months of the vote, all 18 had resigned and were on drug industry payrolls (also showed prices of part-d drugs that were three times prices of identical drugs subject to competitive bidding). Comptroller General starting including in speeches that part-D was enormous gift to the pharmaceutical industry and would come to be a $40T unfunded mandate that would swamp all other budget items.

https://www.pcworld.com/article/243311/former_ibm_ceo_john_opel_dies.html
According to the New York Times, it was Opel who met with Bill Gates, CEO of the then-small software firm Microsoft, to discuss the possibility of using Microsoft PC-DOS OS for IBM's about-to-be-released PC. Opel set up the meeting at the request of Gates' mother, Mary Maxwell Gates. The two had both served on the National United Way's executive committee.

When Boca claimed that they weren't doing software for ACORN (unannounced IBM/PC) there was IBM group in silicon valley formed to do PC software ... every month group checked that Boca wasn't doing software. Then all of sudden, if you wanted to do software for ACORN you had to move to Boca. Boca wanted to not have internal IBM operations competing with them on ACORN (internal politics) ... even to outsourcing with external organizaton where Boca controlled the contract interface.

Starting in early 80s, had HSDT project, T1 (1.5mbits/sec) and faster computer links; and was suppose to get $20M from NSF director to interconnect the NSF supercomputer sites. Then congress cuts the budget, some other things happen and finally an RFP is released (based in part on what we already had running). Preliminary announcement (Mar1986)
http://www.garlic.com/~lynn/2002k.html#12
The OASC has initiated three programs: The Supercomputer Centers Program to provide Supercomputer cycles; the New Technologies Program to foster new supercomputer software and hardware developments; and the Networking Program to build a National Supercomputer Access Network - NSFnet.

... snip ...

IBM internal politics not allowing us to bid (being blamed for online computer conferencing (precursor to social media) inside IBM, likely contributed, folklore is that 5of6 members of corporate executive committee wanted to fire me). The NSF director tried to help by writing the company a letter (3Apr1986, NSF Director to IBM Chief Scientist and IBM Senior VP and director of Research, copying IBM CEO) with support from other gov. agencies ... but that just made the internal politics worse (as did claims that what we already had operational was at least 5yrs ahead of the winning bid), as regional networks connect in, it becomes the NSFNET backbone, precursor to modern internet
https://www.technologyreview.com/s/401444/grid-computing/

Lots of battles with communication group since their mainframe controllers only supported up to 56kbit/sec links, they were constantly spreading misinformation and FUD trying to preserve their position. In mid-80s, they even prepared a report for the corporate executive committee that IBM customers wouldn't be wanting T1 until sometime well into the 90s. 37x5 supported "fat pipes", multiple parallel 56kbit links treated as single link. They surveyed customers and found nobody with more than six 56kbit links in "fat pipe". What they didn't know (or avoided explaining) was typical telco tariff for T1 was about the same as five or six 56kbit links. In trivial survey, we found 200 IBM mainframe customers that would just move to full T1, supported by non-IBM mainframe controller.

trivia2: OASC (mar1986 preliminary announce) funding for software went to NCSA
https://beta.nsf.gov/news/mosaic-launches-internet-revolution
developed MOSAIC (browser). Some of the people left NCSA and did MOSAIC startup (name changed to NETSCAPE when NCSA complained about the use of "MOSAIC").

Last product we did at IBM was HA/CMP ... started out HA/6000 for NYTimes to migrate their newspaper system (ATEX) off VAXCluster to RS/6000; I rename it HA/CMP (High Availability Cluster Multi-Processing) when I start doing technical/scientific cluster scale-up with national labs and commercial cluster scale-up with RDBMS vendors (Ingres, Informix, Sybase, and Oracle who have Vaxcluster support in common source base with their other products and I do API with vaxcluster semantics to simplify the port). Old archive post with reference to Jan92 cluster scale-up meeting with Oracle CEO (16processor by mid92, 128processor by ye92)
http://www.garlic.com/~lynn/95.html#13

Within a few weeks of the Ellison meeting, cluster scale-up is transferred, announced as IBM supercomputer and we were told we couldn't work on anything with more than four processors. We leave IBM a few months later. Later we are brought in as consultants with small client/server startup. Two of the former Oracle people (we had worked with on cluster scale-up) were there responsible for something called "commerce server" and wanted to do payment transactions on the server. The startup had also invented this technology they called SSL they wanted to use, it is now frequently called "electronic commerce". I had absolute authority for everything between the webservers and the financial industry payment networks. I then created "Why Internet Isn't Business Critical Dataprocessing" talk based on the work I had to do for electronic commerce. I was also doing some work with Jon Postel (Internet RFC editor)

and he sponsored my talk at ISI & USC.

another communication group death grip story about severely performance kneecapping microchannel cards as part of their fierce battle fighting off distributed computing and client/server; AWD (workstation division) had PC/RT with AT-bus and had done their own 4mbit token-ring card. Then for the RS/6000 with microchannel, were told they could only use PS2 microchannel cards. One of the examples was the PS2 16mbit token-ring had lower card throughput than the PC/RT 4mbit token-ring card (i.e. a PC/RT 4mbit token-ring server would have higher throughput than RS/6000 16mbit token-ring server, 16mbit t/r microchannel cards design point w/300+ stations doing terminal emulation on single network; aka NOT client/sever). Joke was that RS/6000 limited to the severely performance kneecapped PS2 microchannel cards wouldn't have better throughput than PS2/486 (token-ring, display, disks, etc).

Late 70s, I had been brought into Safeway Oakland datacenter running large loosely-coupled complex serving all the US stores (before the LBO and selling off blocks of stores) ... that was running into horrible throughput problems (apparently all the company and POK performance experts had already been brought through). I was brought into large classroom with piles of SVS system activity reports covering the tables. After about 30mins I started to recognize that a specific shared disk was max'ing around 7 I/Os (aggregate of all activity across all activity reports, during peak worst performance) and asked what it was. It was the shared PDS store controller application library ... with 3cyl PDS directory. Turns out PDS directory search was taking avg of 1.5 3330 cyls, one 19track multi-track search at 60rev/sec or .317sec plus 2nd multi-track search of 9.5 tracks or .158sec for avg of .475sec; followed by seek/search/read the actual (store controller) PDS member application. 3330 was capable of only loading two store controller applications per second for all stores in the country. Solution was to split the store controller application PDS dataset into multiple datasets across multiple disks and creating a unique set of non-shared dedicated store controller dataset DASD for each system.

I've claimed that CKD was a 360 60s tradeoff for limited real storage (for cached disk information) and abundant I/O resources (vtoc, pds directories, etc. & doing multi-track searches) ... trade-off that started to invert by the mid-70s. I've frequently told story before in 60s, as undergraduate, univ hired me fulltime responsible for OS/360. I learned to carefully redo sysgen for dataset placement and pds member order to optimize avg. arm seek and PDS directory multi-track search ... so was already familiar with the problems.

Trivia: earlier I had transferred to IBM San Jose Research and was allowed to wander around IBM and customer datacenters. Disk engineering (blg14) and disk product test (blg15) across the street were running stand-alone, 7x24, prescheduled testing. They had mentioned that they had tried running with MVS, but found it had 15min mean-time-between failure (MTBF) in that environment, requiring manual re-ipl. I offered to rewrite I/O supervisor making it bullet proof and never fail ... with them to do any amount of on-demand, concurrent testing (greatly improving productivity). Downside was they got in habit of trying to blame my systems for problem and I had to spend increasing amount of time playing disk hardware engineer. I made the mistake of writing a research report about the work and happen to mention the MVS 15min MTBF ... bringing down the wrath of the MVS organization on my head (offline told that they tried to have me separated from the IBM company, when that didn't work, they tried to make things unpleasant in other ways).

other trivia: I was increasingly pontificating on mainframe disk performance issues, in early 80s, wrote a tome that between os/360 announce and the early 80s, disk relative system performance had declined by order of magnitude (disks got 3-5 times faster while systems got 40-50 times faster). Some GPD disk division executive took exception to what i wrote and assigned the division performance organization to refute my claims. After a couple weeks they basically came back and I had slightly understated the problem. They then respun the analysis for optimizing DASD configuration for improved system throughput (SHARE 63, B874, 16Aug1984).

Also late 70s, I was told by the MVS DASD group that even if I provided fully functional and tested FBA support (aka 3370 FBA), I still needed a $26M incremental business case ($200M-$300M additional sales) to cover MVS training and documentation changes ... and by-the-way, IBM was selling every disk it was making, so any change from CKD to FBA would just be the same amount of revenue (*AND* as part of justification, I wasn't able to use life-time simplification and savings from changing from CKD to FBA architecture)

Note *ALL* disk hardware was beginning to migrate to FBA ... even 3380 CKD (can be seen in records/track formulas where record size had to be rounded up to 3380 "cell size"). No real CKD disks have been made for decades, all being simulated on industry standard fixed-block disks.

With decision to make all 370s virtual memory, some of the science center people moved to the 3rd flr (taking over the IBM Boston Programming Center) to form the VM370 development group. When they outgrew the 3rd flr, they moved out to the empty (former IBM SBC) bldg in Burlington Mall. Then in the wake of the Future System implosion disaster there was mad rush to get stuff back into the 370 product pipelines and the quick&dirty 3033&3081 efforts were kicked off in parallel. The head of POK also managed to convince corporate to kill VM370 product and move all the people to POK (or otherwise MVS/XA would ship on time). They were planning on not telling the VM370 people until the very last minute to minimize the number that might escape. The move managed to leak early and some number escape into the Boston (this was when DEC was starting VMS development and joke was head of POK was major contributor to DEC VMS). Then there was a witchhunt for source of the leak, fortunattely for me, nobody gave up the source. Note: Endicott managed to save the VM370 product mission, but had to reconstitute a development from scratch (some amount of customer complaints about code quality during this period).

Trivia: a decade+ ago, I was asked to track down the original decision to make all 370s virtual memory. Basically MVT storage management was so bad that regions had to be specified four times larger than used. As a result, a typical 1mbyte 370/165 could only run four concurrent regions ... insufficient throughput to keep system busy and justified. MVT moving to SVS 16mbyte virtual memory (very similar to running MVT in CP67 16mbyte virtual machine), would allow increasing number of regions by factor of four with little or no paging. Pieces of all archived exchanged email (with staff member for the executive making the virtual memory decision).

Revealed: Exxon Made "Breathtakingly" Accurate Climate Predictions in 1970's and 80's. Oil company drove some of the leading science of the era only to publicly dismiss global warming.
https://www.motherjones.com/environment/2023/01/revealed-exxon-made-breathtakingly-accurate-climate-predictions-in-1970s-and-80s/
The oil giant Exxon privately "predicted global warming correctly and skilfully" only to then spend decades publicly rubbishing such science in order to protect its core business, new research has found.

IBM changes between 1968 and 1989

Question about IBM changes between 1968 and 1989, my often referenced account ... starting with Learson trying to prevent the bureaucrats, careerists, and MBAs destroying Watson's legacy.
https://www.linkedin.com/pulse/john-boyd-ibm-wild-ducks-lynn-wheeler/

as I periodically pointed out, in 89/90 commandant of marine corps leverage John Boyd for make over of the corps at a time when IBM was desperately in need of make over. Shortly IBM has one of the largest losses in US history and is being re-orged into the 13 "baby blues" in preparation for breaking up the company.

Especially during the Future System period in the 70s, IBM sales became infamous for FUD (fear, uncertainty, doubt) marketing. Major FS motivation was so complex that the clone controller ("PCM") makers wouldn't be able to keep up. FS was completely different from 370 and was going to completely replace 370. Internal politics during the FS period was shutting down the 370 activities and lack of new 370 products during the period is credited (for extensive FUD marketing) with giving the clone 370 makers (Amdahl, Hitachi/NAS, etc) their market foothold However, FS complexity was so great that even IBM wasn't able to do it. After FS implodes, there is mad rush to get stuff back into the 370 product pipelines, including kicking off the quick&dirty 3033 and 3081 efforts in parallel. From Ferguson & Morris, "Computer Wars: The Post-IBM World", Time Books, 1993
http://www.amazon.com/Computer-Wars-The-Post-IBM-World/dp/1587981394
"and perhaps most damaging, the old culture under Watson Snr and Jr of free and vigorous debate was replaced with *SYNCOPHANCY* and *MAKE NO WAVES* under Opel and Akers. It's claimed that thereafter, IBM lived in the shadow of defeat ... But because of the heavy investment of face by the top management, F/S took years to kill, although its wrong headedness was obvious from the very outset. "For the first time, during F/S, outspoken criticism became politically dangerous," recalls a former top executive."

... snip ...

from IBM Jargon
https://comlay.net/ibmjarg.pdf
FS n. Future System. A synonym for dreams that didn't come true. "That project will be another FS". Note that FS is also the abbreviation for "functionally stabilized", and, in Hebrew, means "zero", or "nothing". Also known as "False Start", etc.

FUD (fud) n. Fear, Uncertainty and Doubt. Attributed to Dr. Gene Amdahl after he left IBM to start his own company, Amdahl, who alleged that "F U D" is the fear, uncertainty and doubt that IBM sales people instill in the minds of potential customers who may be considering our [Amdahl] products.


... snip ...

Amdahl leaves IBM shortly after ACS/360 is shutdown (executives afraid that it would advance the state-of-the-art too fast and IBM would loose control of the market). Note towards the end of the page, lists ACS/360 features that show up more than 20yrs later with ES/9000.

After transferring to San Jose, I would wander around IBM and non-IBM locations in silicon valley, including TYMSHARE. In Aug1976, TYMSHARE had made their CMS-based online computer conferencing system free to SHARE as VMSHARE ... archives here
http://vm.marist.edu/~vmshare

I cut a deal with TYMSHARE to get monthly tape backup of all VMSHARE files for putting up on the IBM internal network and systems (including the online world-wide sales&marketing support HONE systems) ... biggest problem I had was with the lawyers that were concerned internal employees could be contaminated directly exposed to customer information.

On one visit to TYMSHARE they demo'ed ADVENTURE ... having found it on Stanford's SAIL PDP10 and ported it to CMS. I made executable available within IBM (and supplied the source for those that got all points). Within short time, versions with lots more points and PLI language implementations started appearing.

TYMSHARE story was that when executive learned about game playing on TYMSHARE computers, he directed that they be removed since TYMSHARE is for business people and business apps. He changed his mind when he was told that game playing had grown to 1/3rd of TYMSHARE revenue.

Subject: Disk optimization
Date: 17 Jan, 2023
Blog: Facebook
I took two semester hr intro to fortran/compueters, at end of semester was hired to rewrite 1401 MPIO for 360/30. Univ. had 709/1401 and was sold 360/67 for TSS/360 as replacement ... getting a 360/30 temporarily replacing 1401 pending arrival of 360/67. The univ. shutdown the datacenter for weekend ... and I would have the place dedicated (although 48hrs w/o sleep made monday classes hard). Within year of intro class after 360/67 arrived, I was hired fulltime responsible OS/360 (tss/360 never came to production fruition so ran as 360/65 with os/360). Some more details
https://www.linkedin.com/pulse/zvm-50th-lynn-wheeler/

Science center installed virtual machine CP67 (precursor to vm370) at the univ (3rd install after cambridge and mit lincoln labs) and I mostly played with it during my weekend dedicated datacenter windows. Original CP67 I/O was fifo and paging was single 4k transfer at a time. I rewrote 2314 for ordered arm seek and rewrote page I/O to chain multiple page requests in single I/O in optimized rotational order (for both 2314 disk and 2301 fixed head drum) using seek track for records on different tracks at same arm position (original CP67 2301 was 70 page i/os per sec, rewrite could get nearly 270 page i/o per sec, aka 30*9). This was picked up and included in CP67 3.2 and also used for vm370 (although CP67->VM370 dropped and/or greatly simplified a lot of my other undergraduate work ... like dynamic adaptive resource managment, dynamic working set calculations, page replacement algorithms, etc). Trivia: 2301 had room for 4.5 4kbyte blocks/track ... and TSS/360 & CP67 2301 format ... formated nine 4k records per pair of 2301 tracks (with the 5th record spanning the end of the 1st track and the start of the 2nd track).

For VM370 and 3330 paging ... there was room for three 4k pages per track, but for a 155/158 to do track switch CCW proceesing between one 4k page and the next rotating 4k page on different track, retuired formating a 110 byte "dummy" block between 4k records ... which then exceeded 3330 track length. I wrote a program to format different sized dummy records and test being able to do track switch CCW processing between the end of one 4k block and the start of the next ... and had customers run it on every combination with IBM & non-IBM disk controlers as well as IBM & non-IBM processors (some like 158 had integrated channel macrocode that shared execution with the 158 engine execution of 370 microcode). 158 channel processing was the worst/slowess of all systems and disk controllers tested. As aside, the quick&dirty 3033 effort (remap 168 logic to 20% faster chips) used 158 integrated channel microcode and 158 engine (for 303x channel director) with similar slow channel program processing as real 158.

I had also written program that could do full-track read and then rewrite the three 4k pages with specified sized dummy blocks on live production paging devices.

When IBM stoped making 2305 fixed-head disks for 370s ... IBM contracted with Intel for "1655s" electronic paging disks for internal datacenters ... that simulated 1.5mbyte/sec 2305. They could also be configured to run at native (aka effectively FBA) 3mbyte/sec.

re: 3350FH; 2305 had "multiple-exposure" subchannel addresses ... so could queue up channel programs on different subchannel addresses and controller would do real-time choice of channel program to execute. The 3350FH (fixed head feature, like limited 2305 fixed-head disk) only had single subchannel address ... so it wasn't possible to have fixed-head transfer channel program while 3350 disk arm was in motion for seek channel program. I had project to add another exposure to 3350FH ... so I could overlap fixed-head transfer while disk was in motion. However there was a group in POK working on VULCAN ... there own electronic disk for paging and felt my 3350 exposure might impact from their market (getting it canceled). They never got to ship VULCAN ... they were eventually canceled claiming that IBM was selling all electronic memory it was making as higher markup processor memory ... but by that time it was too late to revive my 3350FH multiple exposure.

Unix is dead. Long live Unix! Don't expect to see any more big AIX news. This means the last Unix left is ... Linux
https://www.theregister.com/2023/01/17/unix_is_dead/

Note Palo Alto was working with UCB for BSD port to 370 and with UCLA on Locus port that they initially did to series/1. BSD port then was redirected to PC/RT as an alternative to AIX.
https://en.wikipedia.org/wiki/Berkeley_Software_Distribution

Then port of UCLA Locus was done to both 370 (as aix/370) and ps2 (as aix/ps2) ... implementations totally unrelated to Austin AIX.
https://en.wikipedia.org/wiki/Locus_Computing_Corporation
https://dl.acm.org/doi/10.1145/773379.806615

... original UCLA LOCUS implementation
https://en.wikipedia.org/wiki/Locus_Computing_Corporation#AIX_for_IBM_PS/2_and_System/370
Locus was commissioned by IBM to produce a version of the AIX UNIX based operating system for the PS/2 and System/370 ranges. The single-system image capabilities of LOCUS were incorporated under the name of AIX TCF (transparent computing facility).

... snip ...

ROMP was originally going to be followon to displaywriter and when that got canceled, they decided to retarget to unix workstation market. They contracted with company that had done AT&T unix port to IBM/PC for PC/IX to do one for ROMP which becomes AIX for PC/RT.

IBM provided funding for athena at MIT (x-windows, kerberos, etc) ... equally with DEC. IBM also provided funding to CMU for mach, andrew (toolkit & filesystem), camelot, etc. work ... to the tune of about 50% more than the combined ibm/dec funding for MIT athena. I believe ibm also then provided substantial seed for the (camelot) transarc spin-off ... and then paid again substantially when they bought the transarc spin-off outright.

IBM PASC, started working with Locus in the early '80s and doing ports to S/1 and a couple other boxes in Palo Alto ... including process migration and fractional file caching (in addition to distributed access and full file caching).

Early DCE meetings included key people from Locus, Transarc, and several IBM locations.

there was also misc. other unix work-alike. The AT&T/ibm port of UNIX to TSS ... running as a TSS subsystem (I believe saw a large deployment inside of AT&T). prior to that ... in the early '70s, at least one of the online commercial service bureaus spin-offs of the IBM cambridge science center, did cluster version of CP67 (and then vm370) ... This included single system image and process migration (between systems in loosely-coupled configuration in same datacenter as well as to systems in other datacenters) ... they had data centers on both the east coast and the west coast ... and providing 7x24 access to clients around the world. The IBM hardware required regularly (weekly) scheduled preventive maint (PM) and so one motivation was both intra-datacenter and inter-datacenter process migration (there was no time-slot that could be scheduled to take down a box for PM where there weren't users from someplace in the world expecting uninterrupted service).

in the wake of the future system failure, there was mad rush to get stuff back into the 370 product pipelines (internal politics during FS including shutting down 370 efforts), which included absorbing people doing advanced technology projects into the 370 product development breach).

I was involved in doing 16-way tightly coupled multiprocessor system and we presented at adtech conference, along with the 801/risc group (before most of the adtech groups absorbed into the development breach). I believe it was last adtech conference until the one I held spring of 1982. Old archived post of the conference and part of the agenda, http://www.garlic.com/~lynn/96.html#4a

including talks on VM/370 UNIX implementation, the TSS/370 UNIX PRPQ for bell labs. Note also a group from Stanford had approached Palo Alto about IBM turning out a workstation product they had developed, PASC had YKT workstation group, SJR 925 group, and Boca ACORN (IBM/PC) group in to review the proposal; all three IBM groups claimed they were doing something better and IBM declined. The Stanford people then formed their own company called SUN.

trivia: we had con'ed the 3033 processor engineers to work on the 16-way project in their spare time (lot more interesting than remapping 168 logic to 20% faster chips, well before 3033 announce). Everybody thot it was great until somebody told the head of POK that it might be decades before the POK favorite son operating system (MVS) had effective 16way support. The head of POK then directs the 3033 processor engineers heads down on 3033 only (and don't be distracted) and some of us were invited to never visit POK again. NOTE: IBM doesn't ship a 16-way until after the turn of the century with the z900.

IBM 3081 TCM

Refed: **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **, - **
From: Lynn Wheeler <lynn@garlic.com>
Subject: IBM 3081 TCM
Date: 18 Jan, 2023
Blog: Facebook
During FS, was completely different from 370 and was going to replace all 370s (internal politics as killing off 370 efforts and lack of new 370 products during the period is credited with giving the 370 clone makers their market foothold). When FS implodes, there was mad rush to get stuff back into 370 (hardware & software) product pipelines ... including kicking off quick&dirty 3033&3081 efforts in parallel
http://www.jfsowa.com/computer/memo125.htm
The 370 emulator minus the FS microcode was eventually sold in 1980 as as the IBM 3081. The ratio of the amount of circuitry in the 3081 to its performance was significantly worse than other IBM systems of the time; its price/performance ratio wasn't quite so bad because IBM had to cut the price to be competitive. The major competition at the time was from Amdahl Systems -- a company founded by Gene Amdahl, who left IBM shortly before the FS project began, when his plans for the Advanced Computer System (ACS) were killed. The Amdahl machine was indeed superior to the 3081 in price/performance and spectaculary superior in terms of performance compared to the amount of circuitry.]

... snip ...

... claims that the 3081 required TCMs in order to pack the enormous amount circuity into reasonable volume ... and some end of ACS/360, executives shut it down because they were worried it would advance the state-of-art too fast and IBM would loose control of the market, also has some refs to ACS/360 features showing up more than 20yrs later with ES/9000

... totally different TCM story. The 3880 disk control unit had special hardware path for data transfer (supporting up to 3mbyte/sec) ... however it had significantly slower microprocessor than 3830 precursor disk control unit; greatly increasing channel busy for channel command processing. The 3090 group had sized the number of channels for balanced target system throughput ... assuming 3880 was like a 3830 but capable of 3mbyte/sec transfer. When they found out bad 3880 channel busy really was, the 3090 group realized they had to significantly increase the number of channels (in order to reach target throughput). The increase in channels required an additional TCM ... they semi-facetiously said they would bill the 3880 group for the increase in 3090 manufacturing cost.

trivia: when I transferred to San Jose Research, I got to wander around both IBM and non-IBM datacenters around silicon valley, including disk engineering (bldg14) and disk product test (bldg15) across the street. They were running stand-alone, prescheduled around the clock testing. They said that had tried MVS, but it had 15min mean-time-between failure (MTBF, in that environment), requiring manual re-ipl. I offered to rewrite I/O supervisor making it bullet proof and never fail, allowing any amount of on-demand, concurrent testing (greatly improving productivity). Downside was that whenever they had a problem, they would call me, I had to increasingly diagnose their hardware problems. Along the way, they got the 1st 3033 engineering system (#3 or #4) outside POK, testing took only percent or two of processor ... so found a couple banks of 3330s and put up private online service on the 3033. Early one monday morning, I get a call asking what I had done to the 3033 system over the weekend, there was enormous degradation in throughput. Took an hour or two to get them to admit that somebody had replaced the 3830 with 3880. Testing up until them had been functional, but this was the 1st time any sort of performance operation. They managed to tweak some stuff ... so by the time of 3090, it wasn't nearly as bad as it started out (note: one of the tweaks was caching stuff about previous I/O, if the next I/O was same channel, it helped, ig it was different channel, things were much worse). recent channel I/O

sometime after leaving IBM, got brought in as consultant into small client/server startup. Two of the former oracel people (that we had worked with on 128-way commercial cluster scale-up) were there responsible for something called "commerce server" and they wanted to do payment transactions on the server. The startup had also invented this technology called "SSL" they waned to use, the result is now frequently called "electronic commerce". I had absolute authority over everything between webservers and payment network ... and had to do a lot of documentation and software for operational. I did a talk about "How Internet Wasn't Business Critial Dataprocessing" based on work I had to do for "electronic commerce". I was doing some stuff with Postel (internet standards editor):

During this period, webserver loads were increasing and many start having >90% processor overhead in running FINWAIT list; closing sessions, sequentially scanned list for incoming packets, assumed list would only have a few items. HTTP/HTTPS had enormous number of (short "transaction") sessions in short period of time. The startup installed Sequent Dynix system ... which had previously fixed the FINWAIT problem some time before.

sequent trivia: before leaving IBM, I was asked to participate in SCI standards. After leaving IBM I did some consulting with Convex Exemplar SCI and later consulted for Steve Chen ... at the time Sequent (before bought by IBM and shutdown) CTO ... related to SCI Numa-Q. At that time, Sequent was also running Windows NT on their other multiprocessors and claimed they had done nearly all the work for NT multiprocessor scale-up.

Starting in early 80s, had HSDT project, T1 (1.5mbits/sec) and faster computer links; and was suppose to get $20M from NSF director to interconnect the NSF supercomputer sites. Then congress cuts the budget, some other things happen and finally an RFP is released (based in part on what we already had running). Preliminary announcement (Mar1986)
http://www.garlic.com/~lynn/2002k.html#12
The OASC has initiated three programs: The Supercomputer Centers Program to provide Supercomputer cycles; the New Technologies Program to foster new supercomputer software and hardware developments; and the Networking Program to build a National Supercomputer Access Network - NSFnet.

... snip ...

IBM internal politics not allowing us to bid (being blamed for online computer conferencing (precursor to social media) inside IBM, likely contributed, folklore is that 5of6 members of corporate executive committee wanted to fire me). The NSF director tried to help by writing the company a letter (3Apr1986, NSF Director to IBM Chief Scientist and IBM Senior VP and director of Research, copying IBM CEO) with support from other gov. agencies ... but that just made the internal politics worse (as did claims that what we already had operational was at least 5yrs ahead of the winning bid), as regional networks connect in, it becomes the NSFNET backbone, precursor to modern internet
https://www.technologyreview.com/s/401444/grid-computing/

Lots of battles with communication group since their mainframe IBM controllers only supported up to 56kbit/sec links, they were constantly spreading misinformation and FUD trying to preserve their position and dumb terminal paradigm. In mid-80s, they even prepared a report for the corporate executive committee that IBM customers wouldn't be wanting T1 until sometime well into the 90s. 37x5 supported "fat pipes", multiple parallel 56kbit links treated as single link. They surveyed customers and found nobody with more than six 56kbit links in "fat pipe". What they didn't know (or avoided explaining) was typical telco tariff for T1 was about the same as five or six 56kbit links. In trivial survey, we found 200 IBM mainframe customers that would just move to full T1, supported by non-IBM mainframe controller.

.... circa 1980, the author of REX(X) wrote a client/server multi-user (3270) space war game (in PLI) ..... used the internal SPM (internal superset of combined VMCF, IUCV, and SMSG, originally developed by the IBM Pisa science center for CP67) ... to communicate with the server(/controller) ... RSCS/VNET had SPM support so it was able to be played over the network. Very early, robot players appeared that were beating all the human players (in large part because of faster response). The server/controller then was upgraded to have non-linear increase in energy use as interval between commands decreased less than normal human threshold (somewhat leveling the playing field).

After joining IBM one of my hobbies was enhanced production operating systems for internal datacenters. I also got to spend time at user group meetings, stop by customers. The director of one of the largest financial industry datacenters liked me to stop by and talk technology. At some point the IBM branch manager horribly offended the customer and in retaliation, they ordered an Amdahl system (up until then Amdahl had been selling into technical/univ accounts, but this would be the 1st true blue customer account, lonely Amdahl system in vast sea of blue). I was then asked to go spend 6-12 months on site at the customer (to help obfuscate why the Amdahl system was being ordered). I talk it over with the customer and then decline. I was then told that the branch manager was good sailing buddy of IBM CEO and the 1st commercial Amdahl order would adversely affect his career. If I didn't do this, I could forget having a career, promotions, and/or raises. I still didn't do it. some more here

One of the final nails in the FS coffin was analysis by the IBM Houston Science Center showing 370/195 applications run on FS machine made out of the fastest available technology would have throughput of 370/145 (about factor of 30 times slowdown).

It also had one-level-store ... sort of like TSS/360 ... I would claim that I found out what not to do observing TSS/360, when I did a CMS paged-mapped filesystem ... it never shipped in part because the FS experience had given any page-related filesystem such a bad reputation (even tho I could easily show my CMS page-mapped filesystem had at least three times the throughput of the standard filesystem).

there is folklore that ibm had flow sensor on the inbound side of heat exchange but no flow sensor on the outbound side. one customer lost flow on outbound side ... and by the time thermal sensor tripped it was too late and all the TCMs fried. After that ... flow sensors were installed on all customer outbound side.

Numerous places were sold 360/67 for TSS/360 ... but TSS/360 never came to real production fruition. Many places dropped back to using it as 360/65 for OS/360. A couple places wrote their own virtual memory operating systems. Some use it for IBM CP67 (precursor to VM370). There were references at one point TSS/360 had 1200 people (Fred Brooks Mythical Man Month and typical IBM Hudson Valley extreme bloat) at time that Science Center had 12 people on CP67/CMS.

Univ. of Michigan did virtual memory "MTS" (Michigan terminal system) for their 360/67. Later ported to 370 and MTS/370 saw some life at a number of locations (frequently on Amdahl machines). Very early in 360 days, Lincoln Labs had written LLMPS (lincoln labs mulitprogramming system) ... sort of multitasking, super DEBE ... and was contributed to the SHARE software library. Folklore is that Univ. of Mich. initially scaffolded MTS starting with using LLMPS as base.

Germ of Truth. Early versions of what became UMMPS were based in part on LLMPS from MIT's Lincoln Laboratories. Early versions of what would become MTS were known as LTS. The initial "L" in LTS and in LLMPS stood for "Lincoln".

370/125 and MVCL instruction

From: Lynn Wheeler <lynn@garlic.com>
Subject: 370/125 and MVCL instruction
Date: 21 Jan, 2023
Blog: Facebook
MVCL(/CLCL) trivia: all 360 instructions checked both start and ending address of parameter storage for access before starting execution. 370 MVCL/CLCL were incremental ... so access was tested as instruction executed. However, 115/125 initially implemented MVCL/CLCL as per 360 (take program interrupt before starting execution if couldn't access ending address) . VM/370 was announced for 135 and up ... but not for 125.

I was asked to get VM370 running on 256kbyte 370/125 (NYC office of Norwegian shipping company). VM370 boot had a MVCL instruction clearing storage and testing for end of (real) memory (addressing program interrupt would have end of storage in register). On 125, instruction wouldn't even start because ending address was 16mbytes ... and so appeared to not have sufficient memory. I zapped VM370 IPL code to get around the MVCL.

CP67 would run on 256kbyte machines ... and I had further cut the fixed storage by another 1/3rd to improve things on smaller memory machines. VM370 had also gotten horribly bloated in fixed storage size ... and redid some of the things that I had done for CP67 to improve throughput.

Then the 115/125 group cons me into doing VM370 for five processor 125. 115/125 had nine position memory bus for microprocessors. On 115, all microprocessors (about 800kips) were the same, controllers and 370 (about 80kips 370, avg 10 native instructions per 370 instruction). 125 was the same, but the microprocessor running 370 was 1.2MIPS, 120kips 370, again avg 10 native instruction per 370 instruction) ... including dropping large amounts of VM370 logic into native microcode.

At the same time, Endicott had con'ed me into helping with ECPS ... dropping pieces of VM370 into native microcode for 138/148. In their case, there was 6kbytes of microcode space and 370 instructions would drop approximately byte-for-byte into native code. I was to identify the highest executed 6kbytes of vm370 code for moving into microcode. Old archived post with result of that analysis (top 6kbytes of VM370 kernel executed instructions accounted for 79.55% of VM370 kernel time, moved to native microcode would be ten times faster).
http://www.garlic.com/~lynn/94.html#21

Endicott then objected to the Boeblingen five processor 125 project and escalated to meeting in DPD hdqtrs. I had to sit on both sides of the table arguing for both sides. Endicott did get the Boeblingen effort surppressed.

Endicott then tried to get corporate to allow them to pre-install VM370 on every 138/148 shipped ... but POK was vigorously working to get VM370 product killed ... so that didn't happen.

23Jun1969 Unbundling and Online IBM Branch Offices

Blog: Facebook
Note: branch office 2741 terminals and 23Jan1969 unbundling announcement, IBM started to charge for software, maint., SE services, etc. Previously part of SE training was sort of apprentice program as part of large group onsite at customer. After unbundling announce, IBM couldn't figure out how not to charge for trainee SEs onsite at the customer (large SE group constantly onsite at customer, disrupting IBM's traditional account control, also disrupted critical part of training of new generations of SEs). To address part of the SE training, HONE (hands-on network experience) was created with branch office online access to CP67 (360/67 precursor to VM/370) datacenters for practice running guest operating systems. When 370 initially announced, the HONE CP67 systems were enhanced with simulation for the new 370 instructions ... allowing branch office SEs running 370 guest operating systems (in virtual machines).

One of my hobbies after joining IBM was enhanced production systems for internal datacenters and HONE was long time customer. The cambridge science center had also ported APL\360 to CMS for CMS\APL ... fixing its memory management for large virtual memory workspaces (APL\360 traditionally was 16kbyte workspaces) for demand page environment and added APIs for system services (like file i/o, enabling lots of real world applications). HONE then started offering online APL-based sales&marketing tools ... which then came to dominate all HONE activity ... and SE training with guest operating systems just dwindled away (with SE skill level dropping ... increasingly become phone directory for internal IBM technical contacts).

Some of my earliest IBM trips overseas were HONE asking me to go along for the early non-US HONE installs, first was for EMEA in brand new bldg in Paris, La Defense (hadn't been finished, including landscaping was still brown dirt) then Tokyo (AFE).

Then mid-70s, the US HONE datacenters were consolidated in Palo Alto, also with loosely-coupled, shared DASD, single-system-image; load-balancing and fall-over across complex. Note, in the CP67->VM370, a lot of feature/function was dropped and/or simplified (including multiprocessor support). I spent a lot of 1974, adding it back into VM370 ... some old archived email
http://www.garlic.com/~lynn/2006v.html#email731212
http://www.garlic.com/~lynn/2006w.html#email750102
http://www.garlic.com/~lynn/2006w.html#email750430

early 1975, I was also asked to do a VM370 for the 370/125 group that would support up to five procesors in a tightly-coupled multiprocessor system and ECPS microcode assist for Endicott 138/148 group (Endicott 138/148 got the 125 multiprocessor work canceled because they felt that 5-125 would overlap their performance). Endicott wanted to pre-install VM/370 on every 138/148 shipped, but POK was in the process of convincing corp. to kill VM370 product; and corp veto'ed it. I then retrofitted the multiprocessor support to VM370 for the 370/168 systems at US HONE in Palo Alto (allowing them to double the number of processors in their single-system image complex). Note extensive branch office HONE keyboard activity (first 2741, then 3270) well before PROFS.

370 Virtual Memory Decision

Refed: **, - **, - **, - **, - **, - **, - **
From: Lynn Wheeler <lynn@garlic.com>
Subject: 370 Virtual Memory Decision
Date: 23 Jan, 2023
Blog: Facebook
MVT gave us virtual memory for all 370s. Decade+ ago I was asked if I could track down the decision. I eventually found somebody on staff to executive making decision. Basically MVT storage management was so bad that regions had to be specified four times larger than actually used, as result typical 1mbyte 370/165 only had enough storage for running four regions concurrently; insufficient to keep the system busy and justified. Going to 16mbyte virtual memoy would allow increasing number of regions by a factor of four times with little or no paging. Initially VS2/SVS, little different than running MVT in a 16mbyte CP67 virtual machine. In fact, biggest piece of code was SVC0/EXCP that had same problem as CP67 ... the passed channel programs would have virtual addresses and a copy channel program would have to be made substituting the real addresses for the virtual addresses (the initial implementation in fact, borrowed CCWTRANS from CP67 to craft into SVC0/EXCP). Old post with pieces of the email exchange:
http://www.garlic.com/~lynn/2011d.html#73

... above also references that plan was VS2R1 (SVS) to VS2R2 (MVS) and then FS VS2R3 (aka "Future System"). FS was completely different from 370 and was going to completely replace it. During FS, internal politics was starting to shutdown 370 efforts and the lack of new 370 products is credited with giving clone 370 makers their market foothold. When FS implodes, there is mad rush to get stuff back into 370 product pipelines, including kicking off the quick&dirty 3033&3081 efforts in parallel. Lots more FS
http://www.jfsowa.com/computer/memo125.htm
http://people.cs.clemson.edu/~mark/fs.html

One of the final nails in the FS coffin was analysis by the IBM Houston Science Center ... that if 370/195 apps were converted to FS machine made out of the fastest available technology, they would have throughput of 370/145 (about factor of 30times slowdown).

My long-winded tome that Learson failed trying to save Watson legacy from the bureaucrats, careerists (and MBAs)
https://www.linkedin.com/pulse/john-boyd-ibm-wild-ducks-lynn-wheeler/

After joining IBM, I drank the koolaid and wore 3piece suits for customers ... however after being told I had no career (because I wouldn't take part of a coverup for the CEO's good sailing buddy) ... after that, never bothered again. Besides hobby of doing enhanced production operating systems for internal datacenters ... and wandering around internal datacenters ... I spent some amount of time at user group meetings (like SHARE) and wandering around customers.

Director of one of the largest (customer) financial datacenters liked me to drop in and talk technology. At one point, the branch manager horribly offended the customer and in retaliation, they ordered an Amdahl machine (lonely Amdahl clone 370 in a vast sea of "blue). Up until then Amdahl had been selling into univ. & tech/scientific markets, but clone 370s had yet to break into the IBM true-blue commercial market ... and this would be the first. I got asked to go spend a 6m-12m on site at the customer to obfuscate the reason for the Amdahl order. I talked it over with the customer and said while he would like to have me there it would have no affect on the decision, so I declined the offer. I was then told the branch manager is sailing buddy of IBM CEO and I can forget a career, promotions, raises (more detail in the wild ducks tome) ... after that, I give up on suits and white shirts ... do get feedback from customers that it was refreshing to have somebody other than the standard IBM "empty suits".

I was in all-hands Austin meeting where it was said that Austin had told IBM CEO that it was doing RS/6000 project for NYTimes to move their newspaper system (ATEX) off VAXCluster ... but it would be dire consequences for anybody to let it leak that it wasn't being done.

One day Nick stopped in Austin and all the local executives were out of town. My wife put together hand drawn charts and estimates for doing the NYTimes project for Nick ... and he approved it; possibly contributed to offending so many people in Austin that suggested that we do the project in San Jose.

It started out as HA/6000, but I rename it HA/CMP (High Availability Cluster Multi-Processing) after starting doing technical/scientific cluster scale-up with national labs and commercial cluster scale-up with RDBMS vendors (who had VAXCluster support in the same source base with Unix support ... providing some APIs with VAXCluster semantics made it easier for port to HA/CMP). Within a couple weeks after Jan1992 cluster scale-up meeting with Oracle CEO (16way mid92, 128way ye92), cluster scale-up is transferred (to be announced as IBM supercomputer for technical/scientific *ONLY*) and we are told we can't work on anything with more than four processors. A few months later, we leave IBM.

The Man That Helped Change IBM
https://smallbiztrends.com/2022/08/the-man-that-helped-change-ibm.html
This week I celebrated my 700th episode of The Small Business Radio Show with Nicholas (Nick) Donofrio who began his career in 1964 at IBM. Ironically, I started at IBM in 1981 for the first 9 years of my career. Nick lasted a lot longer and remained there for 44 years. His leadership positions included division president for advanced workshops, general manager of the large-scale computing division, and executive vice president of innovation and technology. He has a new book about his career at IBM called "If Nothing Changes, Nothing Changes: The Nick Donofrio Story".

Nearly all internal IBM logon screens had "For Business Purposes Only" ... IBM San Jose Research had "For Management Approved Uses Only". One year we got visit by corporate security for audit. One of the first things they wanted to do was remove all games. Big public arguments in the auditorium ("games" had been classified as "computer demo" and "human factor research" projects). 6670s (ibm copier3 with computer interface) had been distributed throughout the bldg. The alternate paper drawer had been loaded with colored paper and was used to print the output "separator" page. Since the "separator" page was nearly all blank, we further modified the driver to print random selected quotations. The security audit was also doing off-shift sweeps looking for unsecured classified material ... including 6670 printed output. They found one with separator page that had quotation:
[Business Maxims:] Signs, real and imagined, which belong on the walls of the nation's offices:

1) Never Try to Teach a Pig to Sing; It Wastes Your Time and It Annoys the Pig.
2) Sometimes the Crowd IS Right.
3) Auditors Are the People Who Go in After the War Is Lost and Bayonet the Wounded.
4) To Err Is Human -- To Forgive Is Not Company Policy.


... snip ...
... they complained to management that we had done it on purpose to ridicule them. As an aside, one of the excuses was that people would just disguise private copies ... cluttering up the system worse than having single public versions.

At end of semester taking two credit hr intro to fortran/computers, I was hired to rewrite 1401 MPIO in 360/30 assembler. Univ had been sold 360/67 (for tss/360) to replace 709/1401. 360/30 was brought in temporarily (which had 1401 emulation), to replace 1401 (pending arrival 360/67). Univ. shutdown datacenter for weekends and I had the place dedicated (although 48hrs w/o sleep made monday class hard) ... they gave me a bunch of documents and I got to design monitor, device drivers, interrupt handlers, storage management, error recovery, etc. ... within a few weeks I had 2000 card 360 assembler program. Then with a year of taking intro class, the 360/67 had come in and I was hired fulltime responsible for os/360 (tss/360 never came to production fruition and so 360/67 ran as 360/65 with os/360) ... and I continued to have my weekend dedicated time (later Univ. gets early CP67 from IBM cambridge center and I could play with it on weekends, rewriting a lot the code). Then before I graduate, I'm hired fulltime into small group in the Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing in independent business to better monetize the investment, including offering services to non-Boeing entities. I thot Renton datacenter was possibly largest in the world, couple hundred million $$$, 360/65s arriving faster than they could be installed; boxes constantly staged in hallways around the machine room. They had one 360/75, when used for classified work would deploy a black rope around the 75 area, guards on the corners, black velvet lowered over front panel lights, printer "windows" (front&back). Boeing badges had plastic bar, color indicating employee/management level and engraved name with color that indicated security clearance level. Lots of politics between renton director and CFO ... who only had 360/30 up at Boeing field for payroll; although they enlarge it to install 360/67 for me to play with CP67 (when I'm not doing other stuff).

After I graduate, I join IBM science center (some of the MIT CTSS/7094 people had gone to project MAC on 5th flr, others went to the science center on the 4th flr). A lot of the CP67 code I had rewritten as undergraduate was picked up by IBM and shipped. I get asked to give computer/security classes at gov. agencies ... some old ref (gone 404, but lives on)
http://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml
from Melinda's history
http://www.leeandmelindavarian.com/Melinda#VMHist

disclaimer: never worked for the gov. and didn't/don't have clearance ... but they made sure to tell me (offline) that they know where I was every day of my life back to birth and challenged me to specify dates. I've guessed they justified it because they ran so much of my software ... and it was before the Church commission (I did get into habit of always reminding them I don't have a clearance).

trivia: after it was decided to add virtual memory to all 370s, some of the science center people split off and took over the IBM Boston Programming Center on the 3rd flr (to do VM370). It was only part of the 3rd, bldg directory listed law firm on the rest of the 3rd. However the 3rd flr telco closet was on the IBM side and the one panel had "IBM" in large letters and the other panel had a 3letter gov agency. Note that the Boston/Cambridge anti-war activity had stationed people all over the area and phoned in threat for the 3letter agency to the Boston FBI office ... looking for what bldg (545 tech sq) that got evacuated.

Staff, profs, students from Boston area institutions had online use of the Cambridge system ... and we had to demonstrate really strong security ... especially after business planners in Armonk corp hdqtrs loaded the most valuable company information on the system and were using it remotely.

... not classified, but for secure internet; Last product we did at IBM was HA/CMP. It started out as HA/6000, but I rename it HA/CMP (High Availability Cluster Multi-Processing) after starting doing technical/scientific cluster scale-up with national labs and commercial cluster scale-up with RDBMS vendors (who had VAXCluster support in the same source base with Unix support ... providing some APIs with VAXCluster semantics made it easier for port to HA/CMP). There is Jan1992 meeting with Oracle CEO on cluster scale-up (16way mid92, 128way ye92); old post
http://www.garlic.com/~lynn/95.html#13

Within a few weeks cluster scale-up is transferred (to be announced as IBM supercomputer for technical/scientific *ONLY*) and we are told we can't work on anything with more than four processors. A few months later, we leave IBM.

Later we are brought into small client/server startup as consultants, two of the former Oracle people (in the Ellison meeting) are there responsible for something called "commerce server", the startup had also invented this technology called "SSL" they want to use, it is now frequently called "electronic commerce". I have responsibility for everything between webservers and the financial payment networks. Afterwards I do a talk on "How Internet Isn't Business Critical Dataprocessing" ... based on compensating stuff I had to do for "electronic commerce". I was also doing some stuff with Postel

z/VM 50th - Part 6 .. long winded zm story (before z/vm).
https://www.linkedin.com/pulse/zvm-50th-part-6-lynn-wheeler/

In the early 70s, there was Future System project, totally replace all 360/370 and totally different (internal politics was shutting down 370 efforts, and the lack of new 370 products during the period is credited with giving the clone 370 makers their market foothold). Then when FS implodes (one of the final nails in the coffin was analysis by IBM Houston Science Center that if 370/195 applications were redone for FS machine made out of fastest available hardware, they would have throughput of 370/145 ... factor of 30times slowdown), there is mad rush to get stuff back into the 370 product pipelines, including quick&dirty 3033&3081 efforts in parallel. Lot more FS details
http://www.jfsowa.com/computer/memo125.htm
http://people.cs.clemson.edu/~mark/fs.html

I had been involved in a couple different 370 multiprocessor efforts, including a 16processor machine and got the 3033 processor engineers working on it in their spare time (a lot more interesting than remapping 168 logic to 20% faster chips) that everybody thot was really good ... that is until somebody told the head of POK that it could be decades before POK favorite son operating system (MVS) had effective 16-way support. Then some of us were invited to never visit POK again and the 3033 processor engineers were directed to heads down on 3033 *only*. There is a advanced technology conference where we present 16way 370 and the 801 group present 801/RISC (I claim it was last adtech conference for some years since lots of adtech groups were being thrown into development breach filling the 370 product pipelines). Note: POK doesn't ship 16proc system until after turn of century. Related 85/165/168/3033/3090 email
http://www.garlic.com/~lynn/2019c.html#email810423

Then the head of POK convinces corporate to kill the vm370 product, shutdown the development group, and transfer all the people to POK (claiming that otherwise MVS/XA wouldn't ship on time). They weren't planning to tell the VM370 people until the very last minute to minimize the number that might escape into the Boston area. The information managed to leak and several escaped. This was about the time of VAX/VMS inception and joke was the head of POK was major contributor to VMS. There was witch hunt for the leak, fortunately for me, nobody gave up the leaker. Endicott manages to save the VM product mission, but has to reconstitute a development group from scratch (some customer complaints about code quality during the period). I also was con'ed into helping Endicott do microcode assist for 138/148 (also used in 4331/4341) ... old post with analysis
http://www.garlic.com/~lynn/94.html#21

In the early 80s, I got approval to do presentations on ECPS implementation at customer user group meetings. After presentations at BAYBUNCH (hosted by Stanford SLAC), the Amdahl people would grill me on some of the details. They said they had developed MACROCODE during the 3033 period (370 like instructions running in microcode mode ... enormously simpler and easier to develop than high end machine horizontal microcode). The issue was that IBM was doing a series of trivial 3033 microcode changes required for running MVS ... and MACROCODE made it almost trivial to respond. They were then working on HYPERVISOR, simplified virtual machine in "hardware" (several years later IBM ships LPAR/PR/SM for 3090; took much longer since done in low level horizontal microcode).

POK was finding customers weren't converting from MVS to MVS/XA as planned ... and Amdahl HYPERVISOR made conversion easier by being able to run both MVS and MVS/XA concurrently. Separate from the issue that Amdahl single processor was about same performance as two processor 3081K (and two processor was much better performance than four processor 3081K). Now some of the VM370 went to POK and had done simplified VMTOOL for MVS/XA development (never intended for shipping to customers) ... and it was decided to ship VMTOOL as VM/MA (migration aid) and later VM/SF (system facility) as aid in MVS to MVS/XA conversion. Part of the VMTOOL was also the SIE instruction (both VMTOOL and 3081 SIE instruction were never targeted for performance, production and/or anything other than development; including 3081 was short of microcode space and executing SIE instruction required the microcode to be "paged in"). Old email from trout/3090 processor engineer (as soon as 3033 was out the door, they had started on trout) and they did SIE instruction designed for performance:
http://www.garlic.com/~lynn/2006j.html#email810630

POK then got interested in re-igniting a production virtual machine product for high-end machine and had proposal for couple hundred people (moved to Kingston) to upgrade VMTOOL (VM/MA, VM/SF) to VM370 function and performance. Endicott had an alternative, a system programmer in Rochester had upgraded VM370 with full 370/XA support ... of course POK won.

In the early 80s, I started looking at rewriting VM370 in higher level language. I did a reimplementation of VM370 spool file in Pascal/VS running in virtual address space. The spool file diagnose that did 4k page transfer was synchronous so difficult for high-speed multi-threaded operation. I had HSDT project with T1 (1.5mbits/sec) and faster computer links. For HSDT, I needed RSCS to handle 70 or so 4k transfers/sec per T1 link (contiguous allocation for large files, multi-page block reads & writes, etc) ... and the diagnose interface restricted RSCS to 5-10 4k transfers/sec aggregate (depending on rest of system spool file activity). I held advanced technology conference spring 1982 ... part of the agenda:
http://www.garlic.com/~lynn/96.html#4a

Old 1987 email about trying to get permission for talk on HSDT-SFS at VM Workshop
http://www.garlic.com/~lynn/2011e.html#email870204

The Kingston group got interested in programming in higher level language and series of meetings were scheduled in Kingston ... to be held in function room off the cafeteria. The cafeteria had misunderstood and posted signs for the "ZM" meeting (instead of "VM"). Kingston then assumed control of the effort (called "ZM" after the cafeteria mistake) and at one point had couple hundred people writing specs ... before it was shutdown.

Classified Material and Security

From: Lynn Wheeler <lynn@garlic.com>
Subject: Classified Material and Security
Date: 26 Jan, 2023
Blog: Facebook
re:
http://www.garlic.com/~lynn/2023.html#54 Classified Material and Security

As per my previous post in this thread, I was initially responsible for the "electronic commerce" webserver connections to the financial industry payment networks.

Later we were asked to help word-smith some cal. state legislation. One of the bills they were working on at the time was breach notification. Several of the people were involved in privacy issues and had done several public surveys. The number one issue was data breaches resulted in fraudulent financial transactions. At the time, little or nothing was being done. Nominally organizations take security measures in self protection ... but in this case the institutions weren't at risk, it was the public. It was hoped that publicity from notifications might motivate countermeasures.

Then there was dozen or so federal (state "preemption") bills introduced, about half similar to cal. state legislation and half that effectively had breach requirements that would never be met (and therefor preclude notification). Early on, one of these involved the card associations publishing industry security specification ... and institutions that were certified to the specification wouldn't be required to make notifications. Joke was that every time a certified institution had a breach, their certification was revoked i.e. the only (active) certifications were for institutions that hadn't yet had a breach. I've periodically commented that some gov. contractors seem to have similar attitude that they aren't at risk for a breach, it is the gov (unless it is specifically specified in the contract).

Almost IBM class student; Jan1968, three from IBM cambridge center came out to install CP67 (precursor to VM370) ... which I mostly played with during my dedicated weekend window and rewrote a lot of CP67 code (I also continued redoing lots of OS360). Jun1968 IBM CSC scheduled one week CP67/CMS class at Beverly Hills Hilton. I arrive for the class Sunday night and am told the IBM CP67 members had resigned on Friday (forming one of the 60s online commercial CP67 spinoffs of CSC) and asked if I would teach the class. Then before I graduate, I'm hired fulltime into a small group in the Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing in an independent business unit to better monetize the investment). However, when I graduate, I join IBM CSC (instead of staying at Boeing).

... HONE trivia, after 23Jan1969 unbundling announcement, IBM started to charge for software, maint., SE services, etc. Previously part of SE training was sort of apprentice program as part of large group onsite at customer. After unbundling announce, IBM couldn't figure out how not to charge for trainee SEs onsite at the customer (large SE group constantly onsite at customer, disrupting IBM's traditional account control, also disrupted critical part of training of new generations of SEs). To address part of the SE training, HONE (hands-on network experience) was created with branch office online access to CP67 (360/67 precursor to VM/370) datacenters for practice running guest operating systems. When 370 initially announced, the HONE CP67 systems were enhanced with simulation for the new 370 instructions ... allowing branch office SEs running 370 guest operating systems (in virtual machines).

One of my hobbies after joining IBM was enhanced production systems for internal datacenters and HONE was long time customer. The cambridge science center had also ported APL\360 to CMS for CMS\APL ... fixing its memory management for large virtual memory workspaces (APL\360 traditionally was 16kbyte workspaces) for demand page environment and added APIs for system services (like file i/o, enabling lots of real world applications). HONE then started offering online APL-based sales&marketing tools ... which then came to dominate all HONE activity ... and SE training with guest operating systems just dwindled away (with SE skill level dropping ... increasingly become phone directory for internal IBM technical contacts).

When I 1st joined IBM (CSC), IBM was going through fast growth and after a few months was asked to be a manager. I asked to read the manager's manual over the weekend and came back on Monday and explained why I wouldn't make a good IBM manager (never was asked again).

My father died when I was in Junior High and after that I always had a job to help my mother. Summer I was 11, bucking hay bales w/o gloves, 4July, light firecrackers in palm to demonstrate calluses. I worked for the local hardware store in high school and periodically would be loaned out to local contractors (concrete, framing, roofing, plumbing, drywall, electrical, whatever was needed) ... saving enough money to start college after I graduate. Summer after freshman year I'm foreman on construction job (started with three nine-person crews) ... and one of the ways of dealing with issues was in the parking lot after work ... which isn't exactly a white collar thing. It had been really wet spring and project was way behind schedule ... and started 80+hr weeks, time&half and double time (I was long at IBM before making more per month than that summer). I usually had to go in 30min before start to make sure everything was planned for the 12+hr (w/breaks&lunch) day and supplies were on hand (some of the items had several day lead time, before PERT charts, all items/schedules memorized and constantly checking ... needed things planned out weeks ahead and might have to adjust if there were late deliveries). Overall playing foreman only took 20-30% of my time, rest of time I filled in where ever it was needed.

Back at school take a 2semester hr intro to fortran/computers and at end of semester am hired to re-implement 1401 MPIO on 360/30. Univ was sold 360/67 for tss/360 replacing 709/1401 and 360/30 (that supported 1401 emulation) was temporary until 360/67 comes in. Univ. shuts down datacenter on weekends, which I then have dedicated (although monday classes are hard after 48hrs w/o sleep). I'm given a bunch of manuals and get to design & implement my own monitor, device drivers, interrupt handlers, storage management, error recovery, etc and within a few weeks I have 2000 card assembler program. Within a year of taking intro class, 360/67 arrives and I'm hired fulltime responsible for os/360 (tss/360 never comes to production so 360/67 ran as 360/65 with os/360) ... and continue to have my dedicated weekend window (1st 360/30 as my personal computer and then 360/67).

Before I graduate, I'm hired fulltime into small group in the Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing in independent business unit to better monetize the investment, including offering services to non-Boeing entities). I think Renton datacenter possibly largest in the world (with 360/65s arriving faster than they could be installed). Lots of politics between Renton director and CFO, who only has 360/30 up at Boeing Field for payroll (although they enlarge the machine room to install 360/67 for me to play with when I'm not doing other stuff). When I graduate, I join IBM (CSC) instead of staying at Boeing.

I didn't know about gov. agencies using my code until after joining IBM and asked to teach computer/security classes in DC area. IBM then got a new CSO (came from gov. service, had been head of presidential detail) and I was asked to run around with him some and talk about computer security (and a little bit of physical security rubs off).

http://www.garlic.com/~lynn/2023.html#56 Classified Material and Security

IBM had Registered Confidential ... every page had large faded red number of the copy ... each copy was registered to specific person ... and required to keep under double lock ... and periodically audited by site security.

circa 1980, IBM brought trade-secret lawsuit against disk clone maker for couple billion dollars ... for having acquired detailed unannounced new (3380) disk drive documents. Judge ruled that IBM had to show security proportional to risk ... or "security proportional to value" ... i.e. temptation for normal person finding something not adequately protected and selling it for money ... couldn't be blamed (analogous to requiring fences around swimming pools because children couldn't be expected to not jump in unprotected pool). fences around plant site, guards at gate checking people, access control for buildings, access control inside high security rooms inside buildings, frequent employee education about protecting corporate information, etc.

In that time frame, I had full set of all the ("811" for nov1978 pub date) "Registered Confidential" documents for unannounced/unshipped 370/xa architecture (which would eventually show up w/3081).

For some reason, I got a call from head hunter asking me to interview for job of technical assistant to president of clone 370 processor company (that resold machines manufactured on the other side of the pacific). During the inter viewthere were hints dropped that they were interested in new 370/xa architecture. I politely mentioned that I had recently submitted changes to IBM Employee ethics booklet because I didn't think that it had strong enough ethics guidelines. The interview ended shortly later ... and I never heard from them again.

scurity proportional to risk posts
http://www.garlic.com/~lynn/submisc.html#security.proportional.to.risk

Later the overseas company was involved in federal court case about industrial espionage and because I was listed on the US company's lobby checkin, I had 3hr interview with FBI agent. Afterwards, I wondered who had leaked the information (that I had full copy of the XA documents) ... that likely resulted in the job interview (and later visit by FBI, possibly somebody from site security?).

Command Culture: Officer Education in the U.S. Army and the German Armed Forces:
https://www.amazon.com/Command-Culture-Education-1901-1940-Consequences-ebook/dp/B009K7VYLI/
German junior officers were regularly asked for their opinions and they would criticize the outcome of a large maneuver with several divisions before the attending general had the floor. The American army culture in contrast has historically had a great problem with dissenters and mavericks and just speaking one's mind to a superior officer, disagreeing with or criticizing him could easily break a career.

from "Computer Wars: The Post-IBM World" Ferguson & Morris on failure of Future System:

... and perhaps most damaging, the old culture under Watson Snr and Jr of free and vigorous debate was replaced with sycophancy and make no waves under Opel and Akers. It's claimed that thereafter, IBM lived in the shadow of defeat

... and:

But because of the heavy investment of face by the top management, F/S took years to kill, although its wrongheadedness was obvious from the very outset. "For the first time, during F/S, outspoken criticism became politically dangerous," recalls a former top executive.

... snip ...

Command Culture: Officer Education in the U.S. Army and the German Armed Forces:

As a young officer, Dwight D. Eisenhower wrote an article favoring mechanization of the cavalry.87 The article displeased the chief of infantry greatly and Ike was commanded not only to cease such heretical activities but also to publicly reverse his opinion. He was threatened with a court-martial.88 His superiors expected a fellow officer to become a sycophant.

... snip ...

One of Boyd's briefings at IBM was Organic Design for Command and Control ... which ends with what is really needed is "Appreciation and Leadership". Part of the briefings was observation that US corporate culture was becoming contaminated by former military officers climbing corporate ladder.

loc5019-20:

A rapid coup d'oeil prompt decision, active movements, are as indispensable as sound judgment; for the general must see, and decide, and act, all in the same instant.

... snip ...

Could claim that Boyd takes see/decide/act ... replaces see with observe ... and then adds internal brain processing ... putting observation in context (orientate, learning, knowledge).

There is an AI book from the 90s, where one of the "fathers" of AI (dating back to 60s) in intro says that all AI up until then had been done wrong because it wasn't placing information in "context".

In briefings, Boyd would also emphasize observing from every possible facet ... countermeasure to biases ... observation, orientation, confirmation. cognitive. etc biases Also for many people OODA-LOOP implies step-by-step sequential, rather than all parts running simultaneously and asynchronously.

Late 70s, there was multuser space war game deployed on the internal network and within a few weeks there were "bot" players beating humans. Game was upgraded for nonlinear increase in power use for move intervals below human threshold ... putting things on (partial) level playing field

This is also pretty much how Boyd would describe fly-by-wire for F16 ... human reflexes aren't fast enough.

AI then was more "expert systems", capture sets of rules (from some domain expert) ... akin to Muth's "school solutions" in "Command Culture"
https://www.amazon.com/gp/aw/d/B009K7VYLI/
(contrasted to exercises formulating solutions; with compare&contrast).

How Toyota Turns Workers Into Problem Solvers
http://hbswk.hbs.edu/item/how-toyota-turns-workers-into-problem-solvers

To paraphrase one of our contacts, he said, "It's not that we don't want to tell you what TPS is, it's that we can't. We don't have adequate words for it. But, we can show you what TPS is."

We've observed that Toyota, its best suppliers, and other companies that have learned well from Toyota can confidently distribute a tremendous amount of responsibility to the people who actually do the work, from the most senior, experienced member of the organization to the most junior. This is accomplished because of the tremendous emphasis on teaching everyone how to be a skillful problem solver.

The Starfish and the Spider: The Unstoppable Power of Leaderless Organizations
https://www.amazon.com/Starfish-Spider-Unstoppable-Leaderless-Organizations-ebook/dp/B000S1LU3M/
pg186/loc2059-62:

Experts tried to explain why Toyota plants were able to produce a high-quality product and foster efficient teamwork while GM's were not. Some speculated that GM's problems arose from the growing power of unions. Others, including Drucker, attributed the Japanese success to cultural differences. The Japanese, he said, had "come to accept my position that the end of business is not 'to make money."

pg191/loc2120-25:

Toyota occupied the decentralized sweet spot in the automotive industry. Had it centralized its assembly line to mirror GM's, it would have taken power away from employees and reduced vehicle quality. But on the other hand, had Toyota decentralized too far--doing away with structure and controls and, say, letting each circle work on whatever car it felt like--the company would have had a mess on its hands. Decentralization brings out creativity, but it also creates variance. One Toyota circle might very well make a wonderful automobile, while another might produce a junker. The sweet spot that Toyota found has enough decentralization for creativity, but sufficient structure and controls to ensure consistency.

... snip ...

some four decades ago, congress passes import quotas on foreign autos, reducing competition, and enormously increasing profits with expectation that they would use the money to remake themselves ... however they just pocketed the money and continued busy as usual. As a result, early 80s, there was call for 100% unearned profit tax on the US auto industry.

Then 1990, the industry has the C4 taskforce to (finally?) look at completely remaking themselves and because they were planning on heavily leveraging technology, they invited major technology vendors to send representatives (offline I would chide some of the computer "big iron" people how could the contribute since the suffered from similar problems). One of the issues was the US industry was taking 7-8yrs from start to rolling off the line, with two efforts offset 3-4 years (so it looks like something is coming more frequently, with cosmetic changes in between). Toyota had cut that time in half in the 80s and in 1990 was in the process of cutting it in half again (18-24months) ... allowing it to adapt more quickly to new technologies and changing consumer preferences.

from more recent auto bailouts, they weren't successful in make-over ... too many stakeholders and vested interests trying to preserve status quo.

Boeing to deliver last 747, the plane that democratized flying
https://techxplore.com/news/2023-01-boeing-plane-democratized-flying.html

At end of semester taking two credit hr intro to fortran/computers, I was hired to rewrite 1401 MPIO in 360/30 assembler. Univ had been sold 360/67 (for tss/360) to replace 709/1401. 360/30 was brought in temporarily (which had 1401 emulation), to replace 1401 (pending arrival 360/67). Then within a year of taking intro class, the 360/67 had come in and I was hired fulltime responsible for os/360 (tss/360 never came to production fruition and so 360/67 ran as 360/65 with os/360).

Then before I graduate, I'm hired fulltime into small group in the Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing in independent business to better monetize the investment, including offering services to non-Boeing entities). I thot Renton datacenter was possibly largest in the world, couple hundred million $$$, 360/65s arriving faster than they could be installed; boxes constantly staged in hallways around the machine room. Lots of politics between Renton director and CFO who only had 360/30 for payroll up at Boeing field (although they enlarge the machine room for 360/67 for me to play with, when I'm not doing other stuff).

747-3 was flying skies of Seattle getting FAA flt. certification. There was mockup of 747 cabin just south of Boeing field. Tours would claim that 747 would always be served by at least four jetways for passenger load/unload (because of so many people).

1st heavy and had computer auto landing ... end of seatac runway started to crack because 747s were always landing within a couple ft every time. Claim is they then started slightly varying approach glide slope signal

SJC was also 1st place I saw multiple flt numbers & "change of equipment" ... twa parked some planes overnight in san jose (because it was cheaper than SFO). Early morning the same flt took off for stop in SFO and then on to both Seattle and Kennedy (aka one of the flt numbers had "change of equipment" in SFO). Eventual explanation was paper OAG listed direct flts before connecting flts ... so the SJC flt appeared as "direct" to both Seattle and Kennedy (even tho there was a "change of equipment" for one of them in SFO ... aka a connecting flt by any other name ... gaming the paper OAG).

Many years later (after leaving IBM) ... i was asked into largest airline res system to look at the ten impossible things that they couldn't do. I was given machine readable of every commercial airline flt segment in the world ... and couple of months came back with rewrite that did all ten impossible things. I found one flt (I think it was Honolulu to LAX) that appeared to be listed with 13 different flt numbers (same airline, same take-off, same landing). Then I was told reality, they hadn't really wanted me to do it (they just wanted to tell the parent board that I was working on it) ... in order to do the ten impossible things ... I had to automate some processes that were being performed by several hundred people

decade_ ago, i was asked to track down decision to make all 370s "virtual memory". Eventually found staff to executive that made decision (basically MVT storage management was so bad that had to specify regions four times larger than used, typical 1mbyte 370/165 then only had enough room to run four regions concurrently, insufficient to keep machine busy and justified; going to 16mbyte virtual memory memory allowed number of concurrent regions to be increased by factor of four with little or no paging ... VS2/SVS similar to running MVT in a 16mbyte CP67 virtual machine). old archived post with pieces of email exchange
http://www.garlic.com/~lynn/2011d.html#73

also some mention that VS2/MVS originally was supposed to be "glide path" to "Future System" ... more details:
http://www.jfsowa.com/computer/memo125.htm
http://people.cs.clemson.edu/~mark/fs.html

some discussion of HASP ... and that 7094/7044 DCS was precursor to ASP (disclaimer, my wife was in the gburg JES group and one of the catchers for JES3 ... also coauthor of "JESUS", JES unified system specification, all the features of JES2 & JES3 that respective customers couldn't live w/o ... never came to fruition for various reasons).

I had taken two credit hr intro fortran/computers and at end of semester was hired to rewrite 1401 MPIO for 360/30 in assembler. Univ had been sold 360/67 for tss/360 to replace 709/1401 ... and 1401 was temporarily replaced with 360/30 (pending availability of 360/67). I got to design and implement my own monitor, device drivers, interrupt handlers, storage management, error recovery, etc. ... within a few weeks I had 2000 card assembler program (univ. shutdown datacenter on weekends and I would have the whole place dedicated, although 48hrs w/o sleep made monday classes hard).

Within year of taking intro class (and after 360/67 came in), I was hired fulltime responsible for os/360 (tss/360 never came to production, so 360/67 ran as 360/65 with os/360, conitnued to have my weekend dedicated time). 709 ibsys tape->tape ran student fortran jobs in under sec. Initially 360/65 os/360 ran them in over a minute. I installed HASP and it cuts time in half. I then did reorged sysgen2 for careful placement of datasets and PDS members (optimize arm seek and PDS directory multi-track search) that cuts it by another 2/3rds to 12.9secs/job. OS/360 student fortran never got better than 709 until I install WATFOR.

trivia: early 747 experienced some sabotage ... they had built new 747 plant up in Everett ... north of Seattle ... and lots of workers from Renton (south of Seattle) ... and lived in Renton area and/or further south ... were required to commute to new Paine Field plant.

datacenter trivia: There was a disaster plan to duplicate Renton datacenter (which I thot was possibly largest in the world) up at the new 747 plant at Paine field in Everett (north of Seattle) ... scenario was that Mt. Rainier might heat up and the resulting mud slide would take out the Renton datacenter (justification was the cost to Boeing to be w/o Renton datacenter for week or two ... would be more than the cost of duplicating the datacenter).

23jun1969 unbundling announcement started to charge for maint., SE services, (application) software (made the case that kernel software should still be free), etc. Then "Future System" effort in early 70s was totally different from 370 and was going to completely replace it. Internal politics during the period was killing off 370 efforts and the lack of new 370 during the period is credited with giving 370 clone system makers (like Amdahl) their market foothold. When "FS" imploded there was mad rush to get stuff back into the 370 product pipelines, including kicking off the quick&dirty 3033 & 3081 efforts in parallel. Decision was also to transition to charging for all operating system (kernel) software. more FS details
http://www.jfsowa.com/computer/memo125.htm
http://people.cs.clemson.edu/~mark/fs.html

... all during the FS period, I continued to work on 360 and then 370 stuff ... including ridiculing the FS activity ... which wasn't exactly a career enhancing activity.

One of my hobbies after joining IBM was enhanced production operating systems for internal datacenters. In the morph from CP67->VM370, lots of stuff was dropped or significantly simplified (including bunch of stuff I had done as undergraduate and after joining IBM). I spent much of 1974 moving to VM370 and upgrading my internal CSC/VM (for internal datacenters). With the decision to transition to charging for kernel software, a bunch of my stuff for internal datacenters was selected to be the guinea pig ... and I got to spend a great deal of time with lawyers and business people on guidelines for kernel software charging.

The transition to charging for kernel software was pretty well complete by the early 80s ... and the OCO-wars (IBM "object code only") began ... which can be seen in some of the VMSHARE archive ... aka TYMSHARE started offering its CMS-based online computer conferencing (precursor to modern social media) "free" to the mainframe user group, SHARE in Aug1976 ... archive here:

... all during the FS period, I continued to work on 360 and then 370 stuff ... including periodically ridiculing the FS activity ... which wasn't exactly a career enhancing activity.

the 70s Future System disaster, from Ferguson Morris, "Computer Wars: The Post-IBM World", Time Books, 1993 ....
http://www.amazon.com/Computer-Wars-The-Post-IBM-World/dp/1587981394
... and perhaps most damaging, the old culture under Watson Snr and Jr of free and vigorous debate was replaced with *SYNCOPHANCY* and *MAKE NO WAVES* under Opel and Akers. It's claimed that thereafter, IBM lived in the shadow of defeat ... But because of the heavy investment of face by the top management, F/S took years to kill, although its wrong headedness was obvious from the very outset. "For the first time, during F/S, outspoken criticism became politically dangerous," recalls a former top executive.

some of the MIT 7094/CTSS people went to Project Mac on the 5th flr to do Multics. Others went to the IBM Cambridge Science Center on the 4th flr and did CP40&CP67 (precursor to VM370), internal network, lots of online and performance/throughput applications, etc. The CTSS Runoff was redone for CMS as "SCRIPT". Then in 1969, GML was invented at the science center (name chosen for 1st letters of inventors last name) and GML tag processing was added to CMS SCRIPT. One of the first mainstream IBM documents done in SCRIPT was the 370 Architecture manual (called "REDBOOK" for distribution in red 3-ring binders). SCRIPT command line option would either print the full REDBOOK, or the 370 Principles of Operation subset.

After a decade, GML morphs into ISO standard SGML

After another decade it morphs into HTML at CERN. The first HTML webserver in the US was on the Stanford SLAC (CERN sister institution) VM370 system

4341 looked more like an office credenza
https://www.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP4341.html

bldg15 got an engineering 4341 (proc cycle time was slowed down 10-20% compared to what production models would be) in Jan1979 for disk testing and I was con'ed into doing benchmarks for national lab that was looking at getting 70 for compute farm (sort of (b)leading edge of the coming cluster supercomputing tsunami). Cluster of 5 production models had more throughput, less expensive, smaller footprint, less power and cooling than 3033. Then large companies were making orders for hundreds of vm4341s at a time for placing out in departmental areas (sort of (b)leading edge of the coming distributed computing tsunami).

One of the issues was MVS wanted to play in the (exploding) departmental distributed computing market ... but the only new non-datacenter disks were FBA (3370) and MVS didn't have FBA support. Eventually 3370 CKD emulation was shipped as 3375. However, it didn't do MVS a lot of good, customers were looking at having dozens or scores of VM/4341s systems per support person, while MVS still had large number of support persons per MVS system. Note inside IBM, departmental conference rooms started to be in short supply because so many were being converted to departmental vm4341 distributed systems.

trivia: when I first transferred to San Jose Research, I got to wander around a lot of IBM & non-IBM datacenters ... including bldg14 (disk engineering) and bldg15 (disk product test) across the street. They were still doing prescheduled, around-the-clock, stand-alone testing. They said that they had recently tried MVS ... but it had 15min mean-time-between failure (in that enviroment) requiring manual re-ipl. I offered to rewrite the I/O supervisor making it bullet proof and never fail ... enabling any amount of ondemand concurrent testing, greatly improving productivity. I then wrote ibm internal research paper on the work and happen to mention the MVS 15min MTBF ... bringing down the wrath of the MVS organization on my head. Later when 3380s were getting ready to ship, FE had 57 simulated errors they felt were likely to happen ... and MVS was crashing in all cases ... and in 2/3rds of the cases there was no indication of what cause the failure. Other trivia: bldg15 found with a little tweaking of 4341 microcode that they could do 3380 3mbyte/sec datastreaming testing.

In SJR I was also doing some work for System/R (original SQL/relational implementation) and BofA signed up for joint study with 60 distributed vm/4341s deployed for branches. The corporation was totally preoccupied with EAGLE for the followon to IMS ... so it was possibly to do tech transfer ("under the radar") to Endicott for SQL/DS (later when EAGLE implodes, there is request for how fast could System/R be ported to MVS ... which is eventually announced as DB2 ... originally for decision support only). One of the leading people behind System/R departs for Tandem ... trying to palm off a bunch of stuff on me.

IBM SJR had done internal 4341 VM SSI with 3088/trotter (8 channel CTCA) ... that could do cluster serialization operations in well under a second elapsed time. Then the communication group said that they would veto it shipping to customers unless their cluster operations ran on top of VTAM. Then the cluster operations that ran well under a second were taking half a minute.

Early CP67 under CP67 under CP67 was joint distributed development project with Endicott for initial 370 virtual memory development. CP67 (360/67) was modified to support virtual machine with 370 virtual memory architecture ("CP67H"). Then CP67H was modified to run with 370 virtual memory architecture (instead of 360/67 architecture) and would run in CP67H 370 virtual machine (aka "CP67I"). "CP67I" was in regular production use a year before any real 370 virtual memory hardware and also used for the initial test of engineering 370/145 supporting virtual memory. In Cambridge, the production CP67L system ran on the real 360/67. "CP67H" ran in a "CP67L" 306/67 virtual machine (in part because 370 virtual memory hadn't been announced and needed to be isolated from staff, students, and professors from Boston area institutions also using the cambridge machine), "CP67I" then ran in "CP67H" 370 virtual machine. Then CMS ran in a "CP67I" 370 virtual machine. Later three people came out from San Jose and implemented 3330 and 2305 device support in CP67I ... became CP67SJ ... which would be run on internal IBM real 370 hardware machines both before and after 370 virtual memory was announced (lots of places were still using it after VM370 became available).

National lab benchmark was Fortran "RAIN" that came from the 60s and ran on CDC6600. They were looking for 70 4341s for compute farm (leading edge of cluster supercomputing tsunami) ... It ran in 35.77secs on CDC6600 and it ran in 36.13secs on engineering 4341 (the engineering 4341 had processor cycle reduced by 10-20% from what would ship in production machines).

trivia: with the demise of FS, there is mad rush to get stuff back into 370 product pipeline, including kicking off 3033&3081 in parallel. 3033 starts out with 168 logic remapped to 20% faster chips. They take the 158 integrated channel microcode for 303x channel director. A 3031 is a 158 engine with just 370 microcode (and no integrated channel microcode) and a 2nd 158 engine with the integrated channel microcode (and no 370 microcode) for 303x channel director. A 3032 is a 168-3 modified to use 303x channel directors (aka 158 engines with integrated channel microcode). Some more here (mostly about demise of FS).

https://www.ibm.com/ibm/history/exhibits/storage/storage_PH3340.html

upthread I mention rewriting I/O supervisor for disk engineering (bldg14) and product test (bldg15) to make it bullet proof and never fail so they could switch from stand-alone, prescheduled, around the block, mainframe disk testing to ondemand, any amount of concurrent testing (greatly improving productivity, they had mentioned having tried MVS in that environment and it had 15min MTBF requiring manual re-ipl).

When the engineering 3033 (1st outside pok, #3 or #4) came into bldg15, we setup private online service (disk testing took only percent or two of processing), found a couple strings of 3330 and a 3830 controller (they also ran 3270 coax from the 3033 under the street to my office in SJR/bldg28 ... I had coax switch box between increasing number of systems). At the time, there was somebody doing air bearing simulation (for design of thin-film, floating heads) on the SJR 370/195 ... but even with high priority was only getting a couple turn arounds a month. We set him up on the 3033 ... and even tho it had less than half processing power of 195, he was able to get multiple turn arounds a day. Thin-film, floating heads 1st shipped with 3370 FBA drives:
https://en.wikipedia.org/wiki/History_of_IBM_magnetic_disk_drives#IBM_3370

mentions only systems that supported FBA was DOS & VM. I had offered the MVS DASD group, FBA support ... but they said I needed to show additional $26M ($200M-$300M in sales) to cover cost of publications and education ... but IBM was already selling every disk it made ... and I couldn't use business case of lifetime savings and productivity. Note all disks were already starting to transition to fixed-block, CKD 3380 formulas for records/track required rounding up record size to block size. There haven't been any CKD disks made for decades, all CKD disks are now simulation on industry standard fixed block disks.

other trivia: Even MVS (not having FBA support) 3090 systems had at least a pair of 3370s for operation

3081 trivia: 3033&3081 were quick&dirty efforts kicked off in parallel after the Future System effort imploded. This FS article describes 3081 using warmed over FS technology and likely motivated TCM packaging since the 3081 had such an enormous amount of circuitry (TCM reducing physical space required)
http://www.jfsowa.com/computer/memo125.htm
The 370 emulator minus the FS microcode was eventually sold in 1980 as as the IBM 3081. The ratio of the amount of circuitry in the 3081 to its performance was significantly worse than other IBM systems of the time; its price/performance ratio wasn't quite so bad because IBM had to cut the price to be competitive. The major competition at the time was from Amdahl Systems -- a company founded by Gene Amdahl, who left IBM shortly before the FS project began, when his plans for the Advanced Computer System (ACS) were killed. The Amdahl machine was indeed superior to the 3081 in price/performance and spectaculary superior in terms of performance compared to the amount of circuitry.]

https://www.ibm.com/ibm/history/exhibits/storage/storage_PH3340.html

When the engineering 3033 (1st outside pok, #3 or #4) came into bldg15, we setup private online service (disk testing took only percent or two of processing), found a couple strings of 3330 and a 3830 controller (they also ran 3270 coax from the 3033 under the street to my office in SJR/bldg28 ... I had coax switch box between increasing number of systems). At the time, there was somebody doing air bearing simulation (for design of thin-film, floating heads) on the SJR 370/195 ... but even with high priority was only getting a couple turn arounds a month. We set him up on the 3033 ... and even tho it had less than half processing power of 195, he was able to get multiple turn arounds a day. Thin-film, floating heads 1st shipped with 3370 FBA drives:
https://en.wikipedia.org/wiki/History_of_IBM_magnetic_disk_drives#IBM_3370

mentions only systems that supported FBA was DOS & VM. I had offered the MVS DASD group, FBA support ... but they said I needed to show additional $26M ($200M-$300M in sales) to cover cost of publications and education ... but IBM was already selling every disk it made ... and I couldn't use business case of lifetime savings and productivity. Note all disks were already starting to transition to fixed-block, CKD 3380 formulas for records/track required rounding up record size to block size. There haven't been any CKD disks made for decades, all CKD disks are simulation on industry standard fixed block disks.

other trivia: Even MVS (not having FBA support) 3090 systems had at least a pair of 3370s for operation

vm/4341 and distributed computing trivia (large part, non-datacenter, departmental rooms); 1Jan1983 is cutover from ARPANET (approx. 100 IMP network nodes and 255 host computers) to TCP/IP & "internet" ... at a time when the internal network was rapidly approaching 1000 network nodes (in large part the explosion in vm/4341s ... rapid increase eventually exceeding 4000 internal network nodes) ... these were non-SNA. Old post with a list of corporate locations that added one or more internal network nodes during 1983

Part of the distributed departmental appeal was that science center (and 60s commercial online csc spinoffs) did for cp67 (eventually migrating to vm370) for darkroom, unattended operation. trivia: In the 60s, IBM rented/leased mainframe, charges based on "system meter" ... which ran when ever the processor and/or any channels were busy. One hack was terminal channel program that would allow channel to stop ... but immediately respond when any characters were arriving. The system meter had to have all processors and channels idle for 400ms before stopping (long after IBM had converted from rent/lease to sales, MVS still had a 400ms timer event that would guarantee the "system meter" would never stop).

In SJR I was also doing some work for System/R (original SQL/relational implementation) and BofA signed up for joint study with 60 distributed vm/4341s deployed for branches. The corporation was totally preoccupied with EAGLE for the follow-on to IMS ... so it was possibly to do tech transfer ("under the radar") to Endicott for SQL/DS (later when EAGLE implodes, there is request for how fast could System/R be ported to MVS ... which is eventually announced as DB2 ... originally for decision support only). One of the leading people behind System/R departs for Tandem ... trying to palm off a bunch of stuff on me.

IBM SJR had done internal 4341 VM SSI with 3088/trotter (8 channel CTCA) ... that could do cluster serialization operations in well under a second elapsed time. Then the communication group said that they would veto it shipping to customers unless their cluster operations ran on top of VTAM. Then the same cluster operations that ran well under a second were taking half a minute.

Recent post references old email about 85/165/168/3033/3090 being same machine with slight tweaks (also references that Endicott was moving up from the mid-range)
https://www.linkedin.com/pulse/zvm-50th-part-6-lynn-wheeler/

reference to canceling Amdahl's ACS/360, executives afraid that it would advance state of the art too fast and loose control of the market) ... list some features show up more than 20yrs later with ES/9000 (after ACS/360 canceled, Amdahl leaves IBM).
https://people.cs.clemson.edu/~mark/acs_end.html

trivia: with the demise of FS, there is mad rush to get stuff back into 370 product pipeline, including kicking off 3033&3081 in parallel. 3033 starts out with 168 logic remapped to 20% faster chips. They take the 158 integrated channel microcode for 303x channel director. A 3031 is a 158 engine with just 370 microcode (and no integrated channel microcode) and a 2nd 158 engine with the integrated channel microcode (and no 370 microcode) for 303x channel director. A 3032 is a 168-3 modified to use 303x channel directors (aka 158 engines with integrated channel microcode). Some more here (mostly about demise of FS), also enormous circuitry in 3081 plausible motivation for TCMs (cramming into smaller volume)
http://people.cs.clemson.edu/~mark/fs.html
http://www.jfsowa.com/computer/memo125.htm
The 370 emulator minus the FS microcode was eventually sold in 1980 as as the IBM 3081. The ratio of the amount of circuitry in the 3081 to its performance was significantly worse than other IBM systems of the time; its price/performance ratio wasn't quite so bad because IBM had to cut the price to be competitive. The major competition at the time was from Amdahl Systems -- a company founded by Gene Amdahl, who left IBM shortly before the FS project began, when his plans for the Advanced Computer System (ACS) were killed. The Amdahl machine was indeed superior to the 3081 in price/performance and spectaculary superior in terms of performance compared to the amount of circuitry.]

recent post about early CP67, VM370, and getting con'ed into doing the analysis for ECPS for 138/148 ... also there was effort to get corporate to agree to pre-installing VM370 on every 138/148 shipped ... however head of POK was in the process of convincing corporate to kill the vm370 product and transferrng all the people to POK for MVS/XA. Endicott eventually manages to save the vm370 product mission, but had to reconstitute a development group from scratch.
https://www.linkedin.com/pulse/zvm-50th-part-6-lynn-wheeler/

Then 4331/4341 (follow-on to 138/148) also with ECPS. Now early 80s, there was an effort to use 801/RISC for the microprocessor for controllers, low&mid range 370s (4361/4381 followon for 4331/4341), AS/400 (follow-on for s/38), etc ... for various reasons all those efforts floundered. I contributed to Endicott white-paper rather than using 801/RISC Iliad chip with 370 "microcode" for 4361/4381 ... that chip technology was reaching the point where nearly all 370 could be implemented directly in silicon. Boeblingen was doing the ROMAN chipset that implemented 370 with performance of 168 (I also had a proposal for cluster 370, see how many ROMAN chipsets I could cram in a rack).

A few years later doing HA/6000, which I rename HA/CMP (High Availability Cluster Multi-Processing) for cluster scale-up, for how many RS/6000 in a rack and how many racks tied together. Then cluster scale-up is transferred for announce as IBM supercomputer (for technical/scientific *ONLY*) and we are told we can't work on anything with more than four processors. We leave IBM a few months later.

Early CP67 under CP67 under CP67 was joint distributed development project with Endicott for initial 370 virtual memory development. CP67 (360/67) was modified to support virtual machine with 370 virtual memory architecture ("CP67H"). Then CP67H was modified to run with 370 virtual memory architecture (instead of 360/67 architecture) and would run in CP67H 370 virtual machine (aka "CP67I"). "CP67I" was in regular production use a year before any real 370 virtual memory hardware and also used for the initial test of engineering 370/145 supporting virtual memory. In Cambridge, the production CP67L system ran on the real 360/67. "CP67H" ran in a "CP67L" 306/67 virtual machine (in part because 370 virtual memory hadn't been announced and needed to be isolated from staff, students, and professors from Boston area institutions also using the cambridge machine), "CP67I" then ran in "CP67H" 370 virtual machine. Then CMS ran in a "CP67I" 370 virtual machine. Later three people came out from San Jose and implemented 3330 and 2305 device support in CP67I ... became CP67SJ ... which would be run on internal IBM real 370 hardware machines both before and after 370 virtual memory was announced (lots of places were still using it after VM370 became available).

A coworker at SJR left IBM and was doing lots of contracting work in silicon valley ... lots of work on HSPICE (fortran chip design) and datacenter support work for senior engineering VP at large VLSI shop. He had reworked AT&T C to 370 with lots of fixes and 370 code optimization ... and then ported the BSD chip tools to 370. One day the marketing rep came in and asked him what he was doing. He said implementing ethernet support so could use SGI graphical workstations as front-ends to the 370s. The marketing rep told him he should be doing token-ring support instead or otherwise the customer might find service won't be as timely as it has been. I almost immediately get an hour phone call loaded with 4-letter words. The next morning the senior engineering VP has press conference and says they are moving everything off 370s to SUN servers. IBM then has bunch of task force analysis to look at why silicon valley wasn't using 370 mainframes (but weren't allowed to consider what the marketing rep had done).

The Pentagon Saw a Warship Boondoggle

Subject: The Pentagon Saw a Warship Boondoggle

Blog: Facebook
The Pentagon Saw a Warship Boondoggle. Congress Saw Jobs. After years of crippling problems and a changing mission, the Navy pushed to retire nine of its newest ships. Then the lobbying started.
https://www.nytimes.com/2023/02/04/us/politics/littoral-combat-ships-lobbying.html
But the Pentagon last year made a startling announcement: Eight of the 10 Freedom-class littoral combat ships now based in Jacksonville and another based in San Diego would be retired, even though they averaged only four years old and had been built to last 25 years.

http://nypost.com/2009/07/17/cant-fly-wont-die/
Pilots call high-maintenance aircraft "hangar queens." Well, the F-22's a hangar empress. After three expensive decades in development, the plane meets fewer than one-third of its specified requirements. Anyway, an enemy wouldn't have to down a single F-22 to defeat it. Just strike the hi-tech maintenance sites, and it's game over. (In WWII, we didn't shoot down every Japanese Zero; we just sank their carriers.) The F-22 isn't going to operate off a dirt strip with a repair tent.

But this is all about lobbying, not about lobbing bombs. Cynically, Lockheed Martin distributed the F-22 workload to nearly every state, employing under-qualified sub-contractors to create local financial stakes in the program. Great politics -- but the result has been a quality collapse.

... response in 4341 discussion comment about MVS using 370 "RRB" (reset reference bit) instruction.

CP67 release 1 ... delivered to univ (3nd installation, after mit lincoln labs and cambridge itself) would look for pages to replace by scanning all memory looking for 1st page that didn't belong to executing ("in-queue") program ... if none found, it would then start scan over and just pick the first page found ... and then reset next scan start to the immediate next page.

I rewrote it to be highly optimized "global" least recently used algorithm ... (using ISK/SSK ... sort of emulating RRB, which wasn't available on 360/67). Note at the time, the virtual memory academic literature was about "local" LRU algorithms. I also did a variation on dynamic working set for limiting concurrently executing programs (as countermeasure to page thrashing). After joining IBM Cambridge Science Center, my changes were shipped in CP67 Release 3.

IBM Grenoble Scientific Center then modified the CP67 system to implement "local" LRU algorithm for their 1mbyte 360/67 (155 page'able pages after fixed memory requirements). Grenoble had very similar workload as Cambridge but their throughput for 35users (local LRU) was about the same as Cambrige 768kbyte 360/67 (104 page'able pages) with 80 users (and global LRU) ... aka global LRU outperformed "local LRU" with more than twice the number of users and only 2/3rds the available memory.

Then there was decision to add virtual memory to all 370s. A decade ago, I was asked to track down the decision and found somebody that was staff to the executive. Basically MVT storage management was so bad that region sizes had to be specified four times larger than actually used ... typical 1mbyte 370/165 only had enough room four concurrent executing regions, insufficient to keep machine busy (and justified). Going to VS2/SVS (similar to running MVT in CP67 16mbyte virtual machine) allowed number of regions to be increased by four times with little or no paging. I got into dustup with the POK performance group over what LRU replacement algorithm met. They had identified a myopic optimization that scanning for non-changed pages (for replacement) ... met not having to wait for the replaced page to be written out. It wasn't until late in the 70s with MVS ... that they realized that they were selecting high-use linkpack pages for replacement before they would replace low-use application (changed) data pages. Pieces of email exchange about adding virtual memory to all 370s.

Jim Gray had departed IBM SJR for Tandem in fall of 1980. A year later, at Dec81 ACM SIGOPS meeting, he asked me to help a co-worker get his Stanford PHD that heavily involved global LRU (and the "local LRU" forces from the 60s academic work, were heavily lobbying Stanford to not award a PHD for anything involving global LRU). Jim knew I had detailed stats on the Cambridge/Grenoble global/local LRU comparison (showing global significantly outperformed local). IBM executives stepped in and blocked me sending a response for nearly a year (I hoped it was part of the punishment for being blamed for online computer conferencing in the late 70s through the early 80s on the company internal network ... and not that they were meddling in the academic dispute).

Date: 05 Feb, 2023

another communication group death grip story about severely performance kneecapping microchannel cards as part of their fierce battle fighting off distributed computing and client/server; AWD (workstation division) had PC/RT with AT-bus and had done their own 4mbit token-ring card. Then for the RS/6000 with microchannel, AWD was told they could only use PS2 microchannel cards. One of the examples was the PS2 16mbit token-ring had lower card throughput than the PC/RT 4mbit token-ring card (i.e. a PC/RT 4mbit token-ring server would have higher throughput than RS/6000 16mbit token-ring server, 16mbit t/r microchannel cards design point w/300+ stations doing terminal emulation on single network; aka NOT client/sever). Joke was that RS/6000 limited to the severely performance kneecapped PS2 microchannel cards wouldn't have better throughput than PS2/486 (token-ring, display, disks, etc).

Note that new research Almaden bldg had been heavily provisioned with CAT5 assuming token-ring. However they would find that 10mbit ethernet over CAT5 had more aggregate LAN bandwidth and lower latency than 16mbit token-ring ... and $69 fast ethernet cards had higher per-card throughput than IBM's $800 microchannel 16mbit token-ring cards.

Late 80s, senior disk engineer got talk scheduled at internal, world-wide, annual communication group conference supposedly on 3174 performance, but opened the talked with statement that the communication group would be responsible for the demise of the disk division. Scenario was that communication group had stranglehold on mainframe datacenters with their corporate strategic ownership of everything that crossed datacenter walls (and were fiercely fighting off distributed computing and client/server). The disk division was seeing data fleeing mainframe datacenters to more distributed computing friendly platforms, with drop in disk sales. The disk division had come up with a number of solutions, but they were constantly being vetoed by the communnication group. GPD/Adstar VP partial countermeasure (to communication group death grip) was investing in distributed computing startups that would use IBM disks. He would have us in periodically to discuss his investments and asked us if we could drop by and provide any assistance. One was "MESA Archival" in Boulder ... spinoff startup of NCAR

How is that possible with the 14th Amendment mandating equal protection under the law? Because this central provision for our alleged rule of law didn't take into account the contrivances of corporate lawyers, corporate judges and corporate-indentured lawmakers.

Corporations that are created by state charters are deemed "artificial persons." States like Delaware and Nevada have made a revenue business out of chartering corporations under permissive laws that concentrate power at the top of autocratic commercial hierarchies, leaving their shareholder-owners with very few options other than to sell. Since the early 1800s, states have chartered corporations giving their shareholders limited liability. The maximum they can lose is the amount of dollars invested in their company's stocks or bonds. The modern history of corporate law is now aimed at maximizing the limited liability of the corporation itself.

pgxiii/loc45-50:
IN DECEMBER 1882, ROSCOE CONKLING, A FORMER SENATOR and close confidant of President Chester Arthur, appeared before the justices of the Supreme Court of the United States to argue that corporations like his client, the Southern Pacific Railroad Company, were entitled to equal rights under the Fourteenth Amendment. Although that provision of the Constitution said that no state shall "deprive any person of life, liberty, or property, without due process of law" or "deny to any person within its jurisdiction the equal protection of the laws," Conkling insisted the amendment's drafters intended to cover business corporations too.

pgxiv/loc74-78:
Between 1868, when the amendment was ratified, and 1912, when a scholar set out to identify every Fourteenth Amendment case heard by the Supreme Court, the justices decided 28 cases dealing with the rights of African Americans--and an astonishing 312 cases dealing with the rights of corporations.

pg36/loc726-28:
On this issue, Hamiltonians were corporationalists--proponents of corporate enterprise who advocated for expansive constitutional rights for business. Jeffersonians, meanwhile, were populists--opponents of corporate power who sought to limit corporate rights in the name of the people.

pg229/loc3667-68:
IN THE TWENTIETH CENTURY, CORPORATIONS WON LIBERTY RIGHTS, SUCH AS FREEDOM OF SPEECH AND RELIGION, WITH THE HELP OF ORGANIZATIONS LIKE THE CHAMBER OF COMMERCE.

The Enormous Limitations of U.S. Liberal Democracy and Its Consequences: The Growth Of Fascism. THE U.S. HAS ONE OF THE LEAST DEMOCRATIC SYSTEMS EXISTING TODAY IN THE DEMOCRATIC WORLD
https://www.counterpunch.org/2023/02/06/the-enormous-limitations-of-u-s-liberal-democracy-and-its-consequences-the-growth-of-fascism/
This bias has created fertile conditions in the U.S. for fascism to grow. As someone who lived under a fascist regime in Spain, and knows fascism when I see it, I am alarmed by the growth of the ultra-right, with similar characteristics to the fascism I knew. Its growth is a consequence of the grave limitations of U.S. liberal democracy. Thus, it is premature to assume that a far-right takeover has been averted; on the contrary, it is time for urgent mobilization to stop it.

Science center installed CP67 at univ (3rd installation after cambridge itself and MIT lincoln labs). It came with automagic terminal type identification support for 2741 and 1052. The univ had some number of ascii/tty (trivia: 360 terminal controller support for tty/ascii came in box labled "heathkit"). I added ascii/tty support and extended automagic terminal type identification to tty/ascii. I then wanted to have single dialup number for all terminal types
https://en.wikipedia.org/wiki/Line_hunting

... didn't quite work, it was possible to switch port line scanner type ... but IBM had taken short cut and hard wired each port line speed.

Thus was born the univ project to build our own clone controller ... building (wire-wrap) channel interface board for Interdata/3 programmed to emulate the IBM controller with the addition of supporting automatic line speed. Later it was enhanced with Interdata/4 for the channel interface and cluster of Interdata/3s for the port interfaces. Interdata (and later Perkin/Elmer) sell it commercially as IBM clone controller. Four of us at the univ. get written up responsible for (some part of the) clone controller business.

We were doing HA/CMP ... it had originally started out as HA/6000 for the NYTimes to move their newspaper system (ATEX) off VAX/Cluster to RS/6000. I then rename it HA/CMP (High Availability Cluster Multi-Processing) when start doing technical cluster scale-up with the national labs and commercial cluster scale-up with the RDBMS vendors (Ingres, Informix, Sybase, and Oracle who have Vaxcluster support in common source base with their other products and I do API with vaxcluster semantics to simplify the port).

Old archive post with reference to Jan92 cluster scale-up meeting with Oracle CEO (16processor by mid92, 128processor by ye92)
http://www.garlic.com/~lynn/95.html#13

Within a few weeks of the Ellison meeting, cluster scale-up is transferred, announced as IBM supercomputer (for technical/scientific *ONLY*) and we were told we couldn't work on anything with more than four processors. We leave IBM a few months later. Later we are brought in as consultants with small client/server startup. Two of the former Oracle people (we had worked with on cluster scale-up) were there responsible for something called "commerce server" and wanted to do payment transactions on the server. The startup had also invented this technology they called SSL they wanted to use, it is now frequently called "electronic commerce". I had absolute authority for everything between the webservers and the financial industry payment networks. I then created "Why Internet Isn't Business Critical Dataprocessing" talk based on the work I had to do for electronic commerce.

Starting in early 80s, had HSDT project, T1 (1.5mbits/sec) and faster computer links; and was suppose to get $20M from NSF director to interconnect the NSF supercomputer sites. Then congress cuts the budget, some other things happen and finally an RFP is released (based in part on what we already had running). Preliminary announcement (Mar1986)
http://www.garlic.com/~lynn/2002k.html#12
The OASC has initiated three programs: The Supercomputer Centers Program to provide Supercomputer cycles; the New Technologies Program to foster new supercomputer software and hardware developments; and the Networking Program to build a National Supercomputer Access Network - NSFnet.

IBM internal politics not allowing us to bid (being blamed for online computer conferencing (precursor to social media) inside IBM, likely contributed, folklore is that 5of6 members of corporate executive committee wanted to fire me). The NSF director tried to help by writing the company a letter (3Apr1986, NSF Director to IBM Chief Scientist and IBM Senior VP and director of Research, copying IBM CEO) with support from other gov. agencies ... but that just made the internal politics worse (as did claims that what we already had operational was at least 5yrs ahead of the winning bid), as regional networks connect in, it becomes the NSFNET backbone, precursor to modern internet

other trivia:

some of the MIT CTSS/7094 people
https://en.wikipedia.org/wiki/Compatible_Time-Sharing_System
had gone to project MAC on 5th flr, for multics
https://en.wikipedia.org/wiki/Multics
others went to the IBM science center on the 4th flr and did virtual machines (cp40/cms & cp67/cms, precursor to vm370),
https://en.wikipedia.org/wiki/CP/CMS
online & performance apps, internal corporate network (see zvm-50th-part-3 account), etc. CTSS RUNOFF
https://en.wikipedia.org/wiki/TYPSET_and_RUNOFF#CTSS

was redone as "script" for CMS. Then GML was invented at the science center in 1969 (letters chosen from 1st letters of inventors last name) and GML tag processing added to script.
http://www.sgmlsource.com/history/sgmlhist.htm
after another decade, GML morphs into ISO standard SGML ... and then after another decade, SGML morphs into HTML at CERN.

Stanford SLAC was heavy VM370 user (followon to CP67) and hosted the monthly bay area user group meetings "BAYBUNCH". SLAC (CERN sister installation) hosted 1st webserver in the US on its VM370 system:

while working on netscape "electronic commerce", was also doing work with one of the payment card processing outsourcers that had hdqtrs office on Hansen Way (block or two from El Camino). I get a call from east coast that largest online service provider was having its internet facing servers crashing ... had started the month before and had all the usual experts in to diagnose the problem. He was going to fly out and buy me a hamburger after work (restaurant/cafe on el camino just south of Hansen Way). While I eat the hamburger, he describes the symptoms. I then say that was one of the problems identified (sort of a crack between the standards specification and implementation) when I was doing IBM HA/CMP ... and provide a quick&dirty patch that he applies later that night. I then try and get the standard server vendors to incorporate a fix ... but they said nobody was complaining (i.e. & service provider didn't want it in the news). Exactly a year later it hit the press when a (different) service provider in NY was having the problem ... and the server vendors pat themselves on the back that they were able to ship fixes within a month.

3380 trivia: original 3380 had 20 track spacings between each data track, that was then cut in half to double number of tracks (& cylinders) for 3380E, and spacing cut again to triple number of tracks (& cylinders) for 3380K ... still same 3mbyte/sec channels. The (IBM) father of risc computing tries to get me to help with his "wide-head" idea ... that handles 18 closely spaced tracks ... surface formated with 16 data tracks plus servo track ... the "wide-head" would follow two servo-tracks on each side of the 16 data tracks transferring data at 3mbytes/sec from each track, 48mbytes/sec aggregate. Problem was IBM mainframe I/O wouldn't support 48mbyte/sec I/O ... anymore than they would support 48mbyte/sec RAID I/O.

Very early 80s, (san jose) bldg26 datacenter had run out of space to meet increased (MVS) computing requirements. Bldg26 was looking at the burgeoning vm/4341s being deployed in departmental areas ... however the CKD simulation (3375) wasn't yet available and ... and the only non-datacenter disks were the 3370 FBA (which MVS didn't support). There were also some studies of MVS system 168-3 CPU use mapping to (MVS?) 4341s. One problem showed up was that their analysis was only MVS "capture" CPU ... and much of those MVS systems only had a 50% "capture-ratio" (i.e. the other 50% of the CPU use was uncaptured/unaccounted for; MVS did measure "wait state" time ... so could infer aggregate total CPU by subtracting total wait state from total elapsed).

Some of the major bldg26 MVS applications required more OS/360 services than provided by the 64kbyte OS/360 simulation in CMS ... however some work out in Los Gatos/bldg29, found that with 12kbytes more in OS/360 simulation code, they could transfer much of the MVS applications that previously wouldn't port to CMS (joke that the CMS 64kbyte OS/360 was more efficient than the MVS 8mbyte OS/360 simulation).

Other trivia: in mid-70s, the VM370/CMS group was greatly expanding the CMS OS/360 simulation (including being able to directly support OS/360 CKD disk I/O). However this was in the period after the "Future System" implosion, quick&dirty efforts to get stuff back into the 370 product pipelines, and head of POK convincing corporate to kill the VM370 product, shutdown the development group and transfer all the people to POK for MVS/XA (claiming otherwise MVS/XA wouldn't be ready to ship on time). In that shutdown ... all the VM370/CMS in-progress & unshipped product work seem to evaporate. Note: Endicott eventually was able to acquire VM370/CMS product mission, but had to reconstitute a development group from scratch.

channel trivia: 1980 STL was bursting at the seams and 300 people from the IMS group were being moved to offsite bldg with dataprocessing back to the STL datacenter. They had tried "remote 3270", but found the human factors totally unacceptable. I get con'ed into doing channel-extender support, placing channel attached 3270s at the offsite bldg ... with no perceived difference in human factors between offsite and in STL. The hardware vendor then tries to get IBM to release my support, but there are some engineers in POK playing with some serial stuff and get it veto'ed (concerned that if it was in the market, it would make it harder to justify releasing their stuff).

In 1988, the IBM branch office asks me to help LLNL get some serial stuff, they are playing with, standardized ... which quickly becomes Fibre Channel Standard (FCS, including some stuff I had done in 1980), initially gbit, full-duplex (2gbit/sec aggregate, i.e. 200mbytes/sec). Then in 1990, the POK stuff is released with ES/9000 as ESCON (when it was already obsolete, approx, 17mbytes/sec).

Then some POK engineers become involved with FCS and define a heavy-weight protocol that drastically reduces the native throughput, eventually released as FICON. The most recently published numbers I've found are a "peak I/O" z196 benchmark which got 2M IOPS using 104 FICON. About the same time a FCS was announced for E5-2600 blades that claimed over a million IOPS (two such native FCS have higher throughput than 104 FICON).

Further aggravating throughput&overhead is requirement for CKD DASD ... which haven't been made for decades, all being emulated on industry standard fixed-block disks.

Performance Predictor, IBM downfall, and new CEO

Performance Predictor, IBM downfall, and new CEO

Science Center, besides doing CP40/CMS & CP67/CMS (virtual machine precursor to VM370), had also ported APL\360 to CMS for CMS\APL (redoing storage managmeent from 16kbyte swapped workspaces, to large virtual memory demand paged workspaces ... and adding APIs for system services like file i/o, enabling real world applications), invented GML in 1969 (after a decade morphs into ISO standard SGML, and after another decade morphs into HTML at CERN), and lots of perfromance tools ... including a system analytical throughput model implemented in CMS\APL. This was made available on (world-wide sales&marketing support) HONE system as the Performance Predictor (SEs could enter customer configuration and workload profiles and as "what-if" questions about configuration and/or workload changes.

I had long left IBM, but turn of century was brought into large financial outsourcing datacenter doing something like half of all US credit card processing (for banks and other financial institutions). They had something like 40+ mainframes @$30M constant rolling upgrades, none older than previous generation; all running 450K cobol statement application, number needed to finish batch settlement in the overnight batch window. They had large performance group that had been managing the care&feeding for decades. I used some other performance analysis technology (from science center days) and found 14% improvement.

There was another performance consultant from Europe that during IBM troubles of the early 90s (and unloading lots of stuff), had acquired the right to descendant of the performance predictor, ran it through a APL->C converter and was using it for large (IBM mainframe and non-IBM) datacenter performance consulting business ... who found a different 7% improvement ... total 21% improvement (savings on >$1B IBM mainframes).

trivia: the outsourcing company had been spun off 1992 from AMEX in the largest IPO up until that time ... several of the executives had previously reported to Gerstner (when he was president of AMEX).

This was when IBM had one of the largest losses in US corporate history and was being reorged into the 13 "baby blues" in preparation for breaking up the company.

http://content.time.com/time/subscriber/article/0,33009,977353-1,00.html

we had already left IBM, but we get a call from the bowels of Armonk (corp hdqtrs) asking if we could help with breakup of the company. Lots of business units were using supplier contracts in other units via MOUs. After the breakup, all of these contracts would be in different companies ... all of those MOUs would have to be cataloged and turned into their own contracts (however, before we get started, the board brings in a new CEO and reverses the breakup).

AMEX had been in competition with KKR for (private equity) LBO (reverse IPO) of RJR and KKR wins. KKR runs into trouble and hires away AMEX president to help with RJR
https://en.wikipedia.org/wiki/Barbarians_at_the_Gate:_The_Fall_of_RJR_Nabisco

The IBM Board then hires former president of AMEX as new CEO, who reverses the breakup and uses some of the same tactics used at RJR (gone 404, but lives on at wayback machine)

other MVS / VM370 SMP trivia:

Standard SMP MVS statement was that it only had 1.2-1.5 throughput of single processor. 158&168 multiprocessor configurations had processor cycle reduced by 10% (to account for cross-cache protocol chatter) so two processor hardware was only 1.8 times (i.e. 2*0.9) a single processor. Then throw in the significant MVS multiprocessor system overhead and you only get 1.2-1.5 times single processor.

After joining IBM, one of my hobbies was enhanced production operating systems for internal datacenters and the online world-wide sales&marketing HONE systems were long time customer. In the morph of CP67->VM370, they greatly simplified and/or dropped (including a lot of my stuff done as undergraduate as well as the multiprocessor support). I spent 1974 moving lots of the dropped CP67 features and performance to VM370. It was about this time that the US HONE datacenters were consolidated in palo alto ... with max configured loosely-coupled, single-system image (i.e. eight systems sharing large disk farm) with load-balancing and fall-over. I then retrofitted CP67 multiprocessor support to VM370 initially so HONE could add a 2nd processor to each systems (for 16 processors total in single-system image complex). I had further optimized the CP67 SMP support for super short pathlengths and played some games with "cache affinity" to improve cache hit rate ... SMP systems able to frequently hit twice throughput (offsetting hardware only running at 1.8 of single processor)

IBM's 3033. "The Big One": IBM's 3033
https://www.ibm.com/ibm/history/exhibits/3033/3033_intro.html

early 70s, IBM had the "Future System" project, going to completely replace 370 and totally different. During the period, 370 efforts were being shutdown/killed (credited with giving 370 clone makers their market foothold). Then when FS implodes, there is mad rush to get stuff back in the 370 product pipelines, including kicking off the quick&dirty 3033&3081 efforts in parallel ... some more detail
http://www.jfsowa.com/computer/memo125.htm
http://people.cs.clemson.edu/~mark/fs.html

I had gotten sucked into a 16-processor 370 project and we had co-opted the 3033 processor engineers into working on it in their spare time (lot more interesting than remapping 168-3 logic to 20% faster chips. Everybody thot it was really great until somebody tells the head of POK that it could be decades before POK's favorite son operating system (MVS) had effective 16-way support. Then some of us were invited to never visit POK again and the 3033 processor engineers were directed to heads down on 3033 "only" (and no distractions) ... IBM doesn't ship a 16-processor mainframe until after the turn of the century.

Channel extender with full duplex t1 ... 1.5mbits/sec .... in house was quarter sec or less ... for 3277 had .086 hardware plus .20-.25 system response .... when they used best of my systems it was down to .11 system response. 3278/3274 hardware response was .3-.5 secs (3270 channel attached controllers for 300+ terminals)

Trivia in-house stl had 327x direct channel attached controllers across all channels with dasd for the 168-3 systems. The channel-extender box was several times faster than channel attached 327x controllers ... moving all 327x controllers to remote bldg ... met that the same 3270 traffic done with significantly reduced channel busy (thru fast channel extender box) ... which increased dasd thruput and improved overall system thruput by 10-20%. Some suggestion to use the channel extender boxes for all systems ... including all in-house 327x channel attached controllers (improving system thruput for all systems).

A similar installation was done for IBM Boulder (used T1 optical infrared modem)

By comparison MVS was typically multiple seconds system response.

1980 was start of studies showing .25 sec response (or better) showed improved productivity ... however you needed on of my highly optimized vn370 systems with .11 system response plus channel attached 3270 controller with 3277 terminals that had .086 hardware response. For 3278 they moved lots electronics back into controller (to reduce manufacturing cost) ... but it significantly increased coax protocol chatter latency ... so hardware response increased to .3-.5secs

trivia: when 3278 came out (with the enormous protocol chatter latency) ... letter was written to 3278 product administrator about it being much worse device for interactive computing. Eventually he responded that 3278 wasn't designed for interactive computing but "data entry" (i.e. electronic keypunch). note: MVS system response was so bad that MVS users didn't even notice the difference with channel attached 3270 controllers between 3277 and 3278

.... or "why heads roll uphill" ... and from John Boyd:
There are two career paths in front of you, and you have to choose which path you will follow. One path leads to promotions, titles, and positions of distinction.... The other path leads to doing things that are truly significant for the Air Force, but the rewards will quite often be a kick in the stomach because you may have to cross swords with the party line on occasion. You can't go down both paths, you have to choose. Do you want to be a man of distinction or do you want to do things that really influence the shape of the Air Force? To be or to do, that is the question.

... offsite bldg was 300+ terminals ... the three 56kbit links for 50 terminals ... the equivalent would have been something like 6*3 or 18 56kbit links for 300+ terminals.

... 37x5 & T1 support; I had started with HSDT in early 80s for T1 and faster computer links, however IBM 37x5 boxes didn't support more than 56kbit. In mid-80s, the communication group prepared a report for corporate executive committee why customers wouldn't be needing T1 for another decade or so. They had done analysis of customer 37x5 "fat pipes" (multiple parallel 56kbit links treated as single logical link), showing number of customer 2, 3, 4, 5, etc, 56kbit link "fat pipes" ... dropping to zero by six links. What they didn't know (or didn't want to tell the executive committee) was typical telco tariff for T1 was about the same as 6 or 7 56kbit links. When customers got to 300kbit or so aggregate ... they just switched to full T1 (1.5mbits) with non-IBM controllers. At the time, did trivial survey that found 200 customers with full T1 and non-IBM controllers.

Finally communication group forced to come out with full (terrestrial) T1 support, the "3737" which had a whole boatload of motorola 68k processors and memory with a mini-VTAM that simulated CTCA link to host VTAM. The problem was that host VTAM had an embedded "window pacing" algorithm that would hit limit of outstanding RUs well before returning ACKs started arriving (even short-haul terrestrial T1). The pseudo CTCA/VTAM (in 68k processors) would immediately signal "ACK" to the host processor (even before transmitting to remote 3737) ... trying to force host VTAM to continue transmitting RUs. Even with all the memory and processors, the 3737 peaked out around 2mbits/secs (US T1 full-duplex was 3mbits/sec aggregate, EU T1 full-duplex was 4mbits/sec aggregate). It was obvious that 3737 wasn't able to handle long-haul terrestrial T1 (with longer round-trip latency) ... and no chance at all of handling satellite T1 ... single hop round-trip 88,000 miles or at least .47secs and double hop was at least .94secs (double hop was also problem even at 56kbits, STL once tried to double hop satellite with Hursley ... VM370/RSCS worked fine but MVS/JES2 couldn't hack it).

related, circa 1990 study found that host VTAM LU6.2 had 160k instruction pathlength and 15 buffer copies ... compared to UNIX TCP/IP had 5k instruction pathlength and five buffer copies.

other TCP/IP trivia: communication group fiercely fighting off release of mainframe TCP/IP support, but when they lost they changed tactics and claimed they had corporate responsibility for everything that crossed datacenter walls, and it had to be shipped through them ... what shipped got 44kbytes/sec aggregate throughput using nearly whole 3090 processor. I did the enhancements for RFC1044 and in some tuning tests at Cray Research, between 4341 and a Cray, got sustained 4341 channel throughput using only modest amount of 4341 (something like 500 times improvement in bytes moved per instruction executed). Later in the 90s, the communication group hired a silicon valley consultant to implement TCP/IP support directly in VTAM. Initially he demoed TCP/IP running significantly faster than LU6.2. He was then told that everybody "knows" that a "proper" TCP/IP implementation is much slower than LU6.2 and they would only be paying for a "proper" implementation.

Mainframe Assembler

Subject: Mainframe Assembler
Date: 13 Feb, 2023

I had bunch of archived stuff from undergraduate days in the 60s (lots of assembler, 1401 mpio rewrite for 360/30, lots of os/360 stuff, and significant rewrites of early cp67 & cms, as brash youngster took pride in rearranging code in different CP67 parts to have things happen in zero instructions) and science center days in the early 70s, on 800bpi ... then copied to 1600bpi and adding more stuff. I then copied it to 6250bpi and after research moved up the hill to Almaden ... copied to 3420 cartridges ... including 60s&70s archived stuff on three replicated 3420 cartridge copies ... all in the Almaden tape library. Then Almaden was having operational problems where random tapes were being mounted for scratch ... scraching ten of my tapes ... including triple redundant copies of 60s/70s archive.

Shortly before Almaden operations started mounting random tapes as scratch ... Melinda asked if I had early 70s copy of the incremental source update process ... was able to pull them it all off and email, melinda ref:

In the early 80s, I wanted to demonstrate REX(X) was not just another pretty scripting language (before renamed REXX and released to customers). I decided on redoing a large assembler application (dump reader & fault analysis) in REX with ten times the function and ten times the performance, working half time over three months elapsed. I finished early so started writing automated script that searched for most common failure signatures). It also included a pseudo dis-assembler ... converting storage areas into instruction sequences. I had thought that it would be released to customers but for what ever reasons it wasn't (this was in the OCO-wars period) ... but I finally got permission to give talks on the implementation at user group meetings ... and within a few months similar implementations started showing up at customer shops.

side-bar: In aug1976, TYMSHARE started offering their CMS-based online computer conferencing facility, "free" to the user group SHARE

some acp/tpf res trivia:

late 80s, my wife did short stint as chief architect for Amadeus (built off the old 370/195 Eastern Air System/ONE) ... however she backed the Europeans in the use of x.25 (instead of SNA). The communication group then got her replaced ... but it didn't do them much good because Europe went with x.25 anyway ... and replaced their replacement.

... and in the mid 90s, after having left IBM, was asked into largest airline res system ... to look at the ten things they couldn't do ... first starting with ROUTES (finding flts from origin to destination) ... got a full machine readable copy of the OAG (all commercial airline flts for all airlines and all airports in the world). I came back two months later with (RS/6000, unix, c-language) implementation that did all their impossible things. Initial code did all the stuff they did then, 100 times faster (than ACP/TPF implementation, which in part still suffered from 60s technology trade-offs); then adding implementation of all the additional things, reduced it to only ten times faster. Sized, ten rack mount RS/6000-990s could handle all ROUTES requests for all commercial airlines in the world. Less than decade later (2002), cellphone (XSCALE) processor had MIP rate nearly aggregate of those ten 990s (two? or was it three? racks).

Online Computer Conferencing

Blog: Facebook
Note precursor to the internal forums (and social media) ... AUG1976, TYMSHARE
https://en.wikipedia.org/wiki/Tymshare
started offering their CMS-based online computer conferencing service "free" to the mainframe user group SHARE
https://en.wikipedia.org/wiki/SHARE_(computing)
as VMSHARE ... archives here
http://vm.marist.edu/~vmshare

I cut a deal with Tymshare to get a monthly tape dump of all VMSHARE (and later PCSHARE) files to put up on internal systems (including online world-wide sales and marketing support, HONE systems) and the internal network. The biggest problem I had was with IBM lawyers who were concerned that internal employees exposed to customer information, would be contaminated. I was then blamed for online computer conferencing in the late 70s and early 80s on the internal network (larger than arpanet/internet from just about the beginning until some time mid/late 80s). Folklore is that when corporate executive committee was told about it, 5of6 wanted to fire me. It really took off spring of 1981 after distributing a trip report of visit to Jim Gray at Tandem. From ibmjarg
https://comlay.net/ibmjarg.pdf
Tandem Memos - n. Something constructive but hard to control; a fresh of breath air (sic). That's another Tandem Memos. A phrase to worry middle management. It refers to the computer-based conference (widely distributed in 1981) in which many technical personnel expressed dissatisfaction with the tools available to them at that time, and also constructively criticized the way products were [are] developed. The memos are required reading for anyone with a serious interest in quality products. If you have not seen the memos, try reading the November 1981 Datamation summary.

... snip ...

Officially sanctioned software and forums were then created with "moderators" ... including VMTOOLS and PCTOOLS.

other trivia: Before IBM/PC 3270 emulation (and screen scrapping), the author of VMSG (email client, was also used by PROFS) also implemented parasite/story ... CMS app that leveraged VM370 PVM psuedo 3270 (there was also a PVM->CCDN gateway) and a HLLAPI-like programming language.

https://publicintegrity.org/inequality-poverty-opportunity/taxes/pay-fair-share-taxes-biden-state-of-the-union/

Going back further, 2002 congress lets the fiscal responsibility act lapse (gov spending can't exceed tax revenue, on its way to eliminating all federal debt). By 2005, US Comptroller General was including in speeches that nobody in congress was capable of middle school arithmetic for how badly their were savaging the budget. CBO 2010 report for 2003-2009, that tax revenue was cut $6T and spending increased by $6T for $12T deficit (compared to a fiscal responsible budget), first time taxes were cut to not pay for two wars. Sort of confluence of Federal Reserve and Too Big To Fail needed huge federal debt, special interests wanted huge tax cut, and Military-Industrial Complex wanted huge spending increase and perpetual wars.

Opel's obit ...
https://www.pcworld.com/article/243311/former_ibm_ceo_john_opel_dies.html
According to the New York Times, it was Opel who met with Bill Gates, CEO of the then-small software firm Microsoft, to discuss the possibility of using Microsoft PC-DOS OS for IBM's about-to-be-released PC. Opel set up the meeting at the request of Gates' mother, Mary Maxwell Gates. The two had both served on the National United Way's executive committee.

When Boca claimed that they weren't doing software for ACORN (unannounced IBM/PC) there was IBM group in silicon valley formed to do PC software ... every month group checked that Boca wasn't doing software. Then all of sudden, if you wanted to do software for ACORN you had to move to Boca. Boca wanted to not have internal IBM operations competing with them on ACORN (internal politics) ... even to outsourcing with external organization where Boca controlled the contract interface.

IBM Introduces 'Vela' Cloud AI Supercomputer Powered by Intel, Nvidia

IBM Introduces 'Vela' Cloud AI Supercomputer Powered by Intel, Nvidia
https://www.hpcwire.com/2023/02/08/ibm-introduces-vela-cloud-ai-supercomputer-powered-by-intel-nvidia/
Specs first. Each of Vela's nodes is equipped with dual Intel Xeon "Cascade Lake" CPUs (notably forgoing IBM's own Power10 chips, introduced in 2021), octuple Nvidia A100 (80GB) GPUs, 1.5TB of memory and four 3.2TB NVMe drives. In its [(blog post] announcing the system, IBM said the nodes are networked via "multiple 100G network interfaces," and that each node is connected to a different top-of-rack switch, each of which, in turn, is connected to four different spine switches, ensuring both strong cross-rack bandwidth and insulation from component failure. Vela is "natively integrated" with IBM Cloud's virtual private cloud (VPC) environment.

... snip ...

for going on a couple decades, the large cloud operators have claimed that they assemble their servers at 1/3rd the cost of brand name servers. A few years ago, server chip vendors had press that they were shipping at least half their product directly to the cloud megadatacenters (where they did the assembly) ... shortly later IBM sells off its (intel) server business (to lenovo, having previously sold off the IBM/PC business to lenovo).

More than decade ago, there were articles how it was possible, using a credit card, to have large cloud operator spin-up an ondemand supercomputer (from server blades in their megadatacenters) ... which would rank in the top 40 supercomputers in the world (there were also reduced rates if you would preschedule spin-up during off-peak periods)

IBM viewed selling (as much) hardware (as possible) as profit, large cloud operator with possibly dozens of megadatacenters around the world, each megadatacenter with half million or more systems, view hardware, power, cooling, manual operations, etc ... all as costs (to be optimized, with all kind of trade-offs, the cost of all new hardware replacement might be offset by the reduction in power).

IBM ROLM

Subject: IBM ROLM

Blog: Facebook
I had HSDT project in early 80s, T1 and faster computer links. Not long after IBM bought ROLM ... I was told that I needed to show some IBM content. Even for as slow as T1, the only IBM content I could find was the FSD "Zirpel" T1 card for the Series/1. The problem then was when I went to order some Series/1s, I was told that after IBM bought ROLM ... ROLM had ordered a year's backlog of S/1s (ROLM was Data General boxes). The head of ROLM datacenter was former IBMer I had known some years earlier before they left IBM. In return for a couple of their Series/1 orders I was suppose to help them upgrade their development & test from 56kbit/sec links ... which was taking 24hrs to download new test systems into Data General boxes ... to T1 links.

Some years later ... after leaving IBM ... Siemens had acquired ROLM ... and I was dealing with the head of Siemens chip tech who had office out at the ROLM campus ... I had designed a new secure chip for electronic financial transactions and it was going to be fab'ed at a new Siemens secure plant in Germany. While meeting with him, Siemens spun off the chips stuff as Infineon, he became president (and got to ring the bell at NYSE) ... and Infineon had 3 new bldgs built at the intersection of 101 & main in San Jose.

AMEX was in competition with KKR for LBO (private equity, reverse IPO) take-over of RJR and KKR won. They then ran into trouble and hired away AMEX President (Gerstner) to help.
https://en.wikipedia.org/wiki/Barbarians_at_the_Gate:_The_Fall_of_RJR_Nabisco

IBM has one of the largest losses in US company history and was being reorged into 13 "baby blues" in preparation for breaking up the company (Dec1992, "How IBM Was Left Behind")
http://web.archive.org/web/20101120231857/http://www.time.com/time/magazine/article/0,9171,977353,00.html

http://content.time.com/time/subscriber/article/0,33009,977353-1,00.html

we had already left IBM, but we get a call from the bowels of Armonk (corp hdqtrs) asking if we could help with breakup of the company. Lots of business units were using supplier contracts in other units via MOUs. After the breakup, all of these contracts would be in different companies ... all of those MOUs would have to be cataloged and turned into their own contracts.

before we get started, the IBM Board then hires the former president of AMEX as new CEO, who reverses the breakup and uses some of the same tactics used at RJR (gone 404, but lives on at wayback machine)

above some IBM related specifics from

Trivia, also in 1992, AMEX had spun-off much of its dataprocessing and financial outsourcing businesses as "First Data" ... in the largest IPO up until that time. After turn of the century, I'm doing a stint in FDC hdqtrs and some of the executives had previously reported to Gerstner

HSDT was having periodic skirmishes with communication group over T1&faster mainframe links (and their lack of it), mid-80s was having some hardware built on the other side of the Pacific ... friday before a visit, I get an announcement from them about new internal IBM forum about communications with the following definition:
low-speed: 9.6kbits/sec, medium speed: 19.2kbits/sec, high-speed: 56kbits/sec, very high-speed: 1.5mbits/sec

monday morning on wall of conference room on the other side of pacific, there were these definitions:
low-speed: <20mbits/sec, medium speed: 100mbits/sec, high-speed: 200mbits-300mbits/sec, very high-speed: >600mbits/sec

The communication group also prepared a report for corporate executive committee why customers wouldn't be needing T1 until well into the 90s. They had done analysis of customer 37x5 "fat pipes" (multiple parallel 56kbit links treated as single logical link), showing number of customer 2, 3, 4, 5, etc, 56kbit link "fat pipes" ... dropping to zero by 6or7 links. What they didn't know (or didn't want to tell the executive committee) was typical telco tariff for T1 was about the same as 6 or 7 56kbit links. When customers got to 300kbit or so aggregate ... they just switched to full T1 (1.5mbits) with non-IBM controllers. At the time, did trivial survey that found 200 customers with full T1 and non-IBM controllers.

Finally communication group forced to come out with full (terrestrial) T1 support, the "3737" which had a whole boatload of motorola 68k processors and memory with a mini-VTAM that simulated CTCA link to host VTAM. The problem was that host VTAM had an embedded "window pacing" algorithm that would hit limit of outstanding RUs well before returning ACKs started arriving back (even short-haul terrestrial T1), suspending transmission. The pseudo CTCA/VTAM (in 68k processors) would immediately signal "ACK" to the host processor (even before transmitting to remote 3737) ... trying to force host VTAM to continue transmitting. Even with all the memory and processors, the 3737 peaked out around 2mbits/secs (US T1 full-duplex was 3mbits/sec aggregate, EU T1 full-duplex was 4mbits/sec aggregate). It was obvious that 3737 wasn't able to handle long-haul terrestrial T1 (with longer round-trip latency) ... and no chance at all of handling satellite T1 ... single hop round-trip 88,000 miles or at least .47secs and double hop was at least .94secs (double hop was also problem even at 56kbits, STL once tried to double hop satellite with Hursley ... VM370/RSCS worked fine but MVS/JES2 couldn't hack it).

XTP, OSI & LAN/MAC

From: Lynn Wheeler <lynn@garlic.com>
Subject: XTP, OSI & LAN/MAC
Date: 17 Feb, 2023
Blog: Facebook
LAN/MAC trivia: there were some number of gov/military types involved with XTP and some gov. agencies were directing elimination of Internet and move to (OSI) GOSIP. So (for them) XTP was taken to ISO chartered ANSI group responsible for OSI level 3&4 (network&transport) standards (X3S3.3) as "HSP". Eventually they said they couldn't do it because there was ISO directive that they could only standardize protocols that conformed to the OSI model. XTP didn't conform to OSI model because 1) it supported internetworking protocol (non-existent between level 3&4), 2) went directly to LAN MAC interface (non-existent somewhere in middle of OSI level 3) and 3) skipped the level 3/4 interface (directly from transport to LAN MAC).

Middle 80s, (IBM) communication group had been fighting off release of mainframe TCP/IP. When they lost, they changed their tactic and said that because they had corporate strategic ownership for everything that crossed datacenter walls, TCP/IP product had to be released through them. What shipped got aggregate 44kbytes/sec using nearly whole 3090 processor. I did the changes for RFC1044 and in some tuning tests at Cray Research between Cray and 4341, got sustained channel throughput using only modest amount of 4341 processor (something like 500 times improvement in bytes moved per instruction executed). The communication group also strongly opposed me being on (Chesson's) XTP technical advisory board.

IBM Builds An AI Supercomputer On The Cheap In Its Cloud
https://www.nextplatform.com/2023/02/17/ibm-builds-an-ai-supercomputer-on-the-cheap-in-its-cloud/
You could build a Vela machine of your own by shopping for second-hand servers, CPUs and GPUs, and switches out on eBay, and IBM says in a blog unveiling the machine that the components of the machine were chosen precisely do IBM Cloud could deploy clones of this system in any one of its dozens of datacenters around the world. And we would add, do so without having to worry about export controls given the relative vintage of the CPUs, GPUs, and switching involved.

https://smallbiztrends.com/2022/08/the-man-that-helped-change-ibm.html
This week I celebrated my 700th episode of The Small Business Radio Show with Nicholas (Nick) Donofrio who began his career in 1964 at IBM. Ironically, I started at IBM in 1981 for the first 9 years of my career. Nick lasted a lot longer and remained there for 44 years. His leadership positions included division president for advanced workshops, general manager of the large-scale computing division, and executive vice president of innovation and technology. He has a new book about his career at IBM called "If Nothing Changes, Nothing Changes: The Nick Donofrio Story".

... I was in all-hands Austin meeting where it was said that Austin had told IBM CEO that it was doing RS/6000 project for NYTimes to move their newspaper system (ATEX) off VAXCluster ... but it would be dire consequences for anybody to let it leak that it wasn't being done.

One day Nick stopped in Austin and all the local executives were out of town. My wife put together hand drawn charts and estimates for doing the NYTimes project for Nick ... and he approved it. Possibly contributed to offending so many people in Austin that suggested that we do the project in San Jose.

It started out as HA/6000, but I rename it HA/CMP (High Availability Cluster Multi-Processing) after starting doing technical/scientific cluster scale-up with national labs and commercial cluster scale-up with RDBMS vendors (who had VAXCluster support in the same source base with Unix support ... providing some APIs with VAXCluster semantics made it easier for port to HA/CMP). Within a couple weeks after Jan1992 cluster scale-up meeting with Oracle CEO (16way mid92, 128way ye92), cluster scale-up is transferred (to be announced as IBM supercomputer for technical/scientific *ONLY*) and we are told we can't work on anything with more than four processors. A few months later, we leave IBM.

Bernie Sanders: 'Oligarchs run Russia. But guess what? They run the US as well'. The veteran senator is now part of Joe Biden's inner circle, and is still fighting his country's vast inequalities
https://www.theguardian.com/us-news/2023/feb/19/bernie-sanders-oligarchs-ok-angry-about-capitalism-interview
"Well, the fact is the Wall Street Journal is shocked - flabbergasted! - that an American president would have the courage to mention in his speech, say, that the oil industry made $200bn in profit, while jacking up prices for everyone; they are shocked to hear that a president wants to take on the greed of the pharmaceutical industry; shocked to hear a president talk about the need to raise teacher salaries. Joe Biden is far more conservative than I am. But to his credit, I think he has seen what the progressive movement is doing in this country. And he feels comfortable with some of our ideas - and I appreciate that."

Rail Unions Warned Us: Greed is Dangerous
https://www.counterpunch.org/2023/02/21/rail-unions-warned-us-greed-is-dangerous/
In contract negotiations last year, they denounced a business model known as "precision scheduled railroading," which aims to boost profits by running bigger and faster trains with smaller crews. The practice has even earned a nickname among rail workers: "positive shareholder reaction." Combined with a lack of guaranteed sick pay, this created dangerous conditions for overworked rail employees.

... but didn't mention the track maintenance issue ... which has been around for at least decades ... and then going back to mid-1800s

Years Before East Palestine Disaster, Congressional Allies of the Rail Industry Intervened to Block Safety Regulations. Records show an all-out push to delay and repeal train safety regulations.

In 2015 alone, Norfolk Southern retained 47 federal lobbyists and focused on fighting against ECP regulation. The company disclosed that it "opposed additional speed limitations and requiring ECP brakes." Other rail giants, including BNSF and CSX, deployed lobbyists on the regulations as well, records show.

The Bunker: Tarnished Silver Bullets. This week in The Bunker: the Pentagon's preoccupation with fools-gold-plated warplanes means we end up with costly weapons that can't fly as often; Navy recruiting woes; a grim invasion anniversary; and more.

IBM 5100

From: Lynn Wheeler <lynn@garlic.com>
Subject: IBM 5100

ACIS started out in the early 80s ... I think Danbury ... originally included something like $200M to give out in grants to univ ... other projects also ... involved in corporate sponsored univ. network BITNET:
https://en.wikipedia.org/wiki/BITNET
... co-worker at the (cambridge) science center was responsible for the internal network, technology also used for bitnet.
https://en.wikipedia.org/wiki/Edson_Hendricks
https://www.linkedin.com/pulse/zvm-50th-part-3-lynn-wheeler/
science centers started in mid-60s (nearly 20yrs before) ... cambridge, houston, palo alto, los angelos, grenoble, pisa, etc. Early/mid 70s, 5100 done at palo alto science center (not los gatos science center, Los Gatos was ASDD location and then morphed into VLSI center)
https://en.wikipedia.org/wiki/IBM_5100
Palo Alto also did the APL microcode assist for 370/145, claims that it ran (some) apl as fast as 370/168

Note after unbundlining announcement, HONE was originally created for SEs to have online practice with guest operating systems running on CP/67 (precursor to vm370, done at cambridge science center). Cambridge also did port of APL\360 to CP67/CMS for CMS\APL. HONE then also started deploying CMS\APL-based online sales&marketing tools ... and the use for guest operating system just dwindled away. Early mid-70s, the US HONE datacenters were consolidated in Palo Alto across the back parking lot from Palo Alto Science Center ... which had morphed CMS\APL into APL\CMS for VM370/CMS

Google Tells Some Employees to Share Desks After Pushing Return-to-Office Plan

Google Tells Some Employees to Share Desks After Pushing Return-to-Office Plan
https://gizmodo.com/google-cloud-return-to-office-remote-work-big-tech-1850149200

I took 2 semester hr intro to fortran/computers. At the end of the semester got job redoing 1401 MPIO to 360/30 (unit record front end for 709 tape->tape) ... univ. shutdown datacenter on weekends and I had the whole place dedicated for 48hrs straight (although 48hrs w/o sleep made monday classes hard). Within year of taking intro course, I'm hired fulltime responsible for OS/360 (univ. had been sold 360/67 for TSS/360 ... which never came to production so ran as 360/65 with os/360). I get a 2741 terminal next to desk in my office. Then before I graduate, I'm hired fulltime into a small group in the Boeing CFO office to help with the formation of Boeing Computer Services (consolidate all dataprocessing into an independent business unit to better monetize the investment, including offering services to non-Boeing entities). I thot Renton datacenter was possibly largest in the world, 360/65s were arriving faster than they could installed, boxes constantly staged in hallways around machine room. Lots of politics between head of Renton datacenter and CFO ... who only had a 360/30 up at Boeing field for payroll, although they enlarge it to install 360/67 for me to play with (when I'm not doing other stuff). Then when I graduate, I join the science center in Cambridge (instead of staying at Boeing).

Late 70s, at san jose research and friday's after work, we frequently discussed how to get the (mostly) IBM computer illiterate to use computers. Then there is rapidly spreading rumor that members of the corporate executive committee were using email to communicate ... and start seeing managers rerouting 3270 terminal order to their desks (back when 3270 were part of annual budget and required VP level sign-off) ... which typically were powered on in the morning and went through the day unused, just burning PROFs menu into the screen (saw this symptom continue through the early 90s, when PS2/486 with large displays ... redirected to manager desks as a form of status symbol and implying some computer literacy). Along the way, there was business case that showed 3yr amortized 3270 was about same monthly as business phone that appeared standard on all desks.

from (silicon valley) "real programmers"
Real Programmers never work 9 to 5. If any real programmers are around at 9am, it's because they were up all night.

... snip ...

... for the 10% that do 90% of the work, they have to concentrate on complex issues and interruptions destroy that concentration (they also are proficient in programming languages, analogous to natural language proficiency, think&dream in the language w/o needing translation) ... also applies to cubicles & "open offices"

Google got it wrong. The open-office trend is destroying the workplace.
