trivia: confluence of 23Jun1969 unbundling and Future System; company
managed to make case that kernel software should still be free. then
this mentions that major motivation for Future System project was
countermeasure to clone controllers
https://www.ecole.org/en/session/49-the-rise-and-fall-of-ibm
make FS systems so complex that clone controller makers wouldn't be
able to keep up. Note that during FS ... since FS was completely
different than 370 and was going to completely replace 370
... internal politics was shutting down 370 efforts. Then from the law
of unintended consequences ... the lack of new 370 is credited with
giving clone 370 makers their market foothold (FS was suppose to be
countermeasure to clone controllers, but then responsible for clone
370 market foothold). Of course, FS was so complex even IBM wasn't
able to pull it off ... some additional info
http://www.jfsowa.com/computer/memo125.htm
note: one of the final nails in the FS coffin was study by Houston Science Center that if 370/195 applications were redone for FS machine made out of the fastest available hardware ... it would have throughput of 370/145 (about 30 times slowdown).
with the failure of FS, there was then mad rush to get stuff back into the 370 product pipelines ... including kicking off the quick&dirty 3033&3081 projects in parallel. Also the rise of clone 370 systems seemed to reverse the decision not charging for kernel software ... and some of my enhanced production operating systems stuff (I had started doing after joining IBM) for internal datacenters was selected to be the initial guinea pig for charge-for kernel software

Onward, Christian fascists. Trump's legacy will be the empowerment of
Christian totalitarians
https://www.salon.com/2020/01/03/onward-christian-fascists_partner/
Trump has filled his own ideological void with Christian fascism. He
has elevated members of the Christian right to prominent positions,
including Mike Pence to the vice presidency, Mike Pompeo to secretary
of state, Betsy DeVos to secretary of education, Ben Carson to
secretary of housing and urban development, William Barr to attorney
general, Neil Gorsuch and Brett Kavanaugh to the Supreme Court and the
televangelist Paula White to his Faith and Opportunities
Initiative. More importantly, Trump has handed the Christian right
veto and appointment power over key positions in government,
especially in the federal courts. He has installed 133 district court
judges out of 677 total, 50 appeals court judges out of 179 total, and
two U.S. Supreme Court justices out of nine. Almost all of these
judges were, in effect, selected by the Federalist Society and the
Christian right.
... snip ...
In the 1880s, Supreme Court were scammed (by the railroads) to give
corporations "person rights" under the 14th amendment.
https://www.amazon.com/We-Corporations-American-Businesses-Rights-ebook/dp/B01M64LRDJ/
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.
... snip ...
... testimony falsely claiming authors of 14th amendment intended to
include corporations. 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.

From: Lynn Wheeler <lynn@garlic.com> Subject: Computer Server Market Date: 04 May 2022 Blog: Facebook..... from post this morning in another fora. This corresponds to EC12 era analysis that turn of century, mainframes had been few percent of IBM revenue and dropping, then EC12 period was couple percent (and still dropping) ... but mainframe group was 25% of revenue (nearly all software and services) and 40% of profit:
... other posts in same thread, total "server" market is more like
$100B ($23.6B/quarter):
Intel Data Center Division alone reported revenue of $25.8
billion. And that just Intel, which during this period was losing
market share to AMD, and mostly, while not only, sells CPUs which
constitute, may be, 1/3rd to 1/5th of the total server price.
IBM (Power+z+infrastructure) tends to be 5 to 6% of visible part of
server market by value. So, probably 4% by value if we add invisible
part.
But it does not mean that 4% of server cores are z+POWER, not even
close.
#cores per dollar is far from equal for different vendors.
ARM cores* deliver max. # of cores per dollar, followed by AMD,
followed by Intel, followed by IBM POWER sold with Linux, followed by
IBM POWER sold with IBM OSes, followed, with very big gap, by IBM z.

• z16, 200 processors, ???BIPS (???MIPS/proc),
...
I86 used to be at significant throughput disadvantage to RISC processors ... but around the turn of the century, they started doing chips with hardware layer that translated instructions into RISC micro-ops for execution ... largely negating the difference.
Note writeups had over half the per processor throughput improvement from z10->z196 ... was starting to add cache miss (memory latency) compensation features (that have been in other platforms, in some cases for decades) .... out of order execution, branch prediction, speculative exeecution, etc. Issue were claims that memory latency measured in count of processor cycles is similar to 60s disk latency when measured in 60s processor cycles (being able to do other stuff, aka higher throughput because of reduced idle time while something was waiting for memory)
max-configured z196 went for $30M ... or $600,000/BIPS ... in z196 era, common cloud megadatacenter (with half million or more) systems were E5-2600 blade with (industry standard, compared to 158 iterations) benchmark of 500BIPS (ten times max configured z196). IBM base list e5/2600 blade price was $1815 or $3.63/BIPS (IBM sold off the server business not long after chip makers were claiming that they were shipping half the product directly to cloud megadatacenters). Cloud megadatacenters have also been claiming they assemble their own systems at 1/3rd the cost of brand name systems ($1.21/BIPS ... compared to $600,000/BIPS mainframe).
Since cloud megadatacenters have so drastically reduced cost/system and cost/BIPS (z196 cost/BIPS was nearly 600,000 times that of E5-2600) ... power and cooling has increasingly became major expense ... resulting in them investigating moving to ARM RISC chips .... because they are significantly more processing power efficient (BIPS/core may not be as powerful, but BIPS per power/cooling and BIPS/$$$ is better). Also they have invested heavily in megadatacenter automation ... with staff of 80-120 people for megadatacenter with more than half million systems, avg upwards of 10,000 systems per person).
There was also "peak I/O" benchmark published for z196 ... getting 2M IOPS using 104 FICONS (running over 104 FCS). About the same time there was a FCS announced for e5-2600 that claimed over million IOPS (two such FCS have higher throughput than 104 FICONS running over 104 FCS).

FCS/FICON trivia: 1980, STL (since renamed SVL) was bursting at the seams and were moving 300 from the IMS group to offsite bldg, with dataprocessing service back to STL datacenter. They had tried remote "3270" but found the human factors totally unacceptable. I then get con'ed until doing channel-extender support, placing channel attached 3270 controllers at offsite bldg ... and no perceptible difference for offsite and onsite (STL) 3270 human factors. The hardware vendor then tries to get IBM to release my support ... but there is group in POK playing with some serial stuff and are afraid if my stuff was in the market, it would make it harder to justify releasing their stuff ... and get it veto'd.
Later in 1988, the branch asks if I can help LLNL (national lab) get some serial stuff they are playing with, standardized. It quickly becomes FCS (including some stuff I had done in 1980), starting at 1gbit full-duplex, 2gbit/sec aggregate, i.e. 200mbyte/sec. Then in 1990, the POK people get their stuff released wtih ES/9000 as ESCON (when it is already obsolete, 17mbytes/sec).
Later some POK engineers become involved in FCS and define a heavy-weight protocol (that drastically reduces the standard throughput), which eventually ships as FICON ... z196 2M IOPS needing 104 FICONS compared to two native FCS having over 2M IOPS. Other trivia: mainframe CKD DASD haven't been made for decades, being simulated on industry standard fixed-block disks ... aka, mainframe IOPS benchmarks not only the FICON overhead, but also CKD simulation overhead.

CICS trivia: after taking 2 credit hr to intro computers/fortran, I was hired to rewrite 1401 MPIO for 360/30. The univ was sold 360/67 for tss/360 to replace 709/1401. They got 360/30 replacing 1401 (which could run 1401 emulation) pending the arrival of 360/67. Then within year of taking intro class, was hired fulltime responsible for the mainframe system (tss/360 never came to production fruition, so ran as 360/65 with os/360). Then library gets ONR grant to implement library catalog ... and use part of the money to get 2321 datacell. It was also selected as betatest for original CICS product and debugging CICS was added to my tasks. First "bug" was CICS had some undocumented, hardcoded BDAM options and library had created BDAM datasets with different options and CICS wouldn't start.

The univ. shutdown datacenter from sat 8am to mon 8am ... and for re-implementing 1401 MPIO on 360/30, they let me have the datacenter all to myself for 48hrs straight (although 48hrs w/o sleep could make monday morning classes difficult). They gave me a bunch of manuals and I got to design and implement my own monitor, device drivers, interrupt handlers. error recovery, dispatching, storage management, etc. Within a few weeks, I had 2000 card assembler program.
Note: student fortran jobs ran less then second on 709 ibsys tape->tape. Initially on os/360 (360/67 as 360/65) they ran over a minute. I installed HASP and that cut it in half. I then started doing highly optimized SYSGENs, tear stage2 apart & reorder to optimize datasets (for arm seek) and optimize PDS members (for arm seek and PDS directory multi-track search) that cut it by another 2/3rds to 12.9 seconds. Never got it to better than 709 until installation of UofWaterloo WATFOR (single step monitor).
Before I graduate, I'm hired fulltime into a small group in Boeing CFO's 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, couple hundred million in computers, 360/65s arriving faster than they could be installed, boxes constantly staged in the hallways around the machine room (must have been former aircraft assembly line). Lots of politics between renton datacenter manager and CFO ... who only had a 360/30 up at boeing field for payroll ... although they enlarged it to install a 360/67 for me to play with virtual machine cp67/cms (when I wasn't doing other stuff).

trivia: I had gotten involved with an effort to do a 16-processor 370 and we had con'ed the 3033 processor engineers to work on it in their spare time (a lot more interesting than remapping 168 logic to 20% faster chips). It was going great guns, everybody thought it was great, until somebody told the head of POK that it could be decades before the POK favorite son operating system (MVS) had (effective) 16-way support. Then the head of POK invited some of us to never visit POK again, and directed the 3033 processor engineers to stop being distracted. Once 3033 is out the door, the engineers start on trout/3090. Note IBM doesn't ship 16-way machine until z900 at turn of century (over 20yrs later).
I had transferred out to SJR in silicon valley ... and get to wander around IBM and non-IBM locations ... including bldg14 (disk engineering) and bldg15 (disk product test) across the street. Bldg14 was running 7x24, prescheduled stand-alone mainframe disk testing ... they mentioned they had recently tried MVS, but it had 15min mean-time-between-failure (requiring manual re-ipl) in that environment. I offer to rewrite I/O supervisor making it bullet proof and never fail so they can do any amount of on-demand concurrent testing, greatly improving productivity. I then write up research report and happen to mention the MVS 15min MTBF, bringing down the wrath of the MVS group on my head (even trying to have me separated from the company). I then start delivering "SJR/VM" (in place of CSC/VM), including the I/O rewrite. Later when 3380s were about to ship, FE had 57 simulated regression tests that they felt were likely to occur ... MVS was still failing in all 57 cases (requiring manual re-ipl) ... and in 2/3rds no indication of what caused the failure (given how they treated me, I didn't feel sorry).
bldg15 also gets 3rd or 4th 3033 engineering machine for doing disk channel testing ... which only takes a percent or two of the processor ... we scrounge up 3830 disk controller and a couple 3330 strings and put up our own online service ... and run 3270 coax under the street to 3270 switch box in my office. There was also somebody running air bearing simulation (for floating head design, initially used with 3370 FBA) on SJR MVT 370/195 ... but even with priority designation was only getting couple turn arounds a month. We get him setup on the bldg15 3033 and he gets multiple turn arounds a day (even tho 3033 is only about half the processing power of 195).

195 trivia: shortly after joining IBM ... the 195 group wanted me to help with 370/195 multithreading ... 64 instruction pipeline, out-of-order execution, but w/o speculative execution and/or branch prediction so conditional branches drained the pipeline. 195 was capable of 10mips, but most codes ran at half that (because of pipeline drain). Two simulated instruction streams (@5MIPS) would keep the system busy. However, once 370 virtual memory decision was made ... decided it wasn't worth trying to retrofit virtual memory to 370/195 (even doing it for 370/165 was difficult, little infighting where 165 asked for lots of the architecture be dropped ... or otherwise schedule would have to slip at least six months, they won and all the other machines with the full architecture and software using the full architecture had to be redone).
multithreading trivia: this has reference to killing acs/360
... executives were afraid that it would advance state-of-the-art too
fast and IBM would loose control of the market ... Amdahl leaves IBM
afterwards. Towards bottom references the multithreading patent
... also at bottom ACS/360 features showing up more than 20yrs later
with ES/9000.

1990, there was the "C4 taskforce" in the auto industry to look at significantly remaking themselves (finally; i.e, in the 70s, congress had put import quotas on foreign makers, supposedly to cut competition to give US industry enormous profits that would be used to completely remake themselves, but they just pocketed the money and continued business as usual). C4 taskforce was planning on heavily leveraging IT technology as part of the remake and invited major IT vendors to send representatives to participate; I was selected as one of the reps from IBM. The taskforce could accurately describe what the foreign makers were doing (well) and how US needed to change to compete. Offline, I would chide the reps from IBM POK mainframe, how did they figure on contributing, since they suffered from many of the same (auto industry) problems described by the taskforce.

Note, this claims A10s were so very effective killing tanks (mentions
Iraqi crews felt their tanks were such "sitting duck" targets, that
they were walking away), vehicles, targets with million 30mm shells,

Desert Storm, only the last 100hrs was "land" conflict/war.
https://en.wikipedia.org/wiki/Gulf_War
Note, the stories about fierce tank battles with coalition forces taking no damage, don't mention if the Iraqi tanks had anybody home. Burton talked about getting the cost for the shells reduced from nearly $100 to $13 ($13M compared to the A10 5000 Maverick missiles @$144K, $72M). Burton also talked about proposing a mini-A10 ... with 5-barrel gun, simple enough to be forward deployed ... however, these days it would be a drone. Claims are that the Iraqis learned from Desert Storm to minimize/avoid being targets for US air power (learning to fight with things like IEDs).
Boyd is credited with the "left hook" strategy ... and all sorts of
explanations why the Abram M1s weren't in position to cut off the
retreating Republican Guard ... another possibility is Boyd didn't
realize the disparity between the M1 rated speed and their effective
speed (over distance) being so tightly tethered to supply &
maintenance.

In the meantime, Secretary of Defense Dick Cheney consulted one of his
favorite military strategists, retired Air Force Colonel John
Boyd. During the run up to Desert Storm, Cheney regularly met with
Boyd, where Boyd developed "a version of the von Schlieffen plan"
[5]. Boyd was intimately familiar with the Battle of Cannae, the
Schlieffen plan, as well as the concept of strategic envelopment; he
used his vast knowledge of history to inform his strategic advice to
the DOD

The One Type of Game That Kills Creativity and Innovation. There are
two types of games. One kills creativity and the other is for kids...

virtualization experience starting Jan1968, online at home since Mar1970
From: Lynn Wheeler <lynn@garlic.com> Subject: Computer Server Market Date: 06 May 2022 Blog: Facebookre:
Some of the CTSS people
https://en.wikipedia.org/wiki/Compatible_Time-Sharing_System
went to the 5th flr, project mac, and MULTICS.
https://en.wikipedia.org/wiki/Multics
Others went to the 4th flr, IBM Cambridge Science Center, did virtual
machine CP40/CMS (on 360/40 with hardware mods for virtual memory,
morphs into CP67/C MS when 360/67 standard with virtual memory becomes
available), online and performance apps, CTSS RUNOFF redid for CMS as
SCRIPT, GML invented at science center in 1969 (and GML tag processing
added to SCRIPT, a decade later GML morphs into ISO SGML and after
another decade morphs into HTML at CERN), networking, etc.
https://en.wikipedia.org/wiki/CP/CMS
https://en.wikipedia.org/wiki/Conversational_Monitor_System
CSC thot they would have the official online, time-sharing mission
... but it (& 360/67) officially went to the TSS/360 group ... which
never really came to production fruition ... at one point there was
1200 people involved in TSS/360 when CSC had 12 people doing CP67/CMS
(included secretary). Melinda has a lot more about that history with
some amount of the internal politics.

A decade ago, I was asked to see if I could track down decision to
make all 370s "virtual memory" ... basically it turned out that MVT
storage management was so bad, that regions had to be defined four
times larger than normally used ... a typical 1mbyte 370/165 would
only have four regions ... not sufficient to really keep the machine
busy and justified. Going to virtual memory would allow number of
regions to be increased by four times with little or no paging. Old
archive post with pieces of that email exchange.
http://www.garlic.com/~lynn/2011d.html#73
The decision then was to do VM370 and the resulting effort greatly simplified and/or dropped a lot of stuff from CP67/CMS ... including a lot of CP67/CMS rewrite I had done as undergraduate ... when I graduated, instead of staying at Boeing, I joined IBM at the science center ... and one of my hobbies was enhanced production operating systems for internal datacenters.
Then there was the rise of the "Future System" project (in large part
motivated as countermeasure to clone controllers ... so complex
that it would be nearly impossible to reverse engineer to make clone)
... which was completely different from 370 and was going to
completely replace 370 ... also internal politics during FS was
shutting down 370 efforts (and the lack of new 370 products during the
period is credited with giving clone 370 system makers their market
foothold). When FS finally implodes (too complex even for IBM), there
was mad rush to get stuff back into 370 product pipeline, kicking off
quick&dirty 3033&3081 in parallel. I continue to work on
360/370 stuff all during FS period ... even periodically ridiculing FS
activities ... which wasn't exactly career enhancing activity. more on

370 virtual memory trivia: For 370 virtual memory there were special CP67 modifications that simulated 370 virtual machines ("CP67H", in addition to 360/67 virtual machines), then there was CP67 modifications, "CP67I" that would run on 370 virtual memory architecture (rather than 360/67 virtual memory). CP67I was in general use (in 370 virtual machines running on 360/67 real machines) a year before 370 virtual memory hardware was operations ... and was used to validate the early hardware implementations. CP67I was used in production on large percentage of early 370 virtual memory machines ... even after 370 virtual memory started shipping to customers. Then for various reason internal datacenters started shifting to the official "product" and the number of my internal customer started dropping off ,,, and it was time to start redoing a lot of VM370.
For CP67, had done an automated benchmarking system that could ran
hundreds of benchmarks with different kinds of workload and stress
testing, etc. ... which were the earliest things moved to
VM370. However, VM370 would frequently crash during the benchmarks
... so the next set of changes were the CP67 integrity and kernel
serialization which eliminated the VM370 zombie users cases and system
crashes. Then it was time to start on the performance and function
enhancements. Some old email about having enhanced production "CSC/VM"
available for internal datacenters.

In his book, Data Processing Technology and Economics, Montgomery
Phister, Jr., reports that as of 1968:
Of the 26,000 IBM computer systems in use, 16,000 were S/360 models
(that is, over 60%). [Fig. 1.311.2]
Of the general-purpose systems having the largest fraction of total
installed value, the IBM S/360 Model 30 was ranked first with 12%
(rising to 17% in 1969). The S/360 Model 40 was ranked second with 11%
(rising to almost 15% in 1970). [Figs. 2.10.4 and 2.10.5]
Of the number of operations per second in use, the IBM S/360 Model 65
ranked first with 23%. The Univac 1108 ranked second with slightly
over 14%, and the CDC 6600 ranked third with 10%. [Figs. 2.10.6 and
2.10.7]

https://people.cs.clemson.edu/~mark/acs_legacy.html
trivia: I had taken 2 credit hour intro to fortran/computers ... at the end of semester got a student programming job to rewrite 1401 MPIO for 360/30. The univ had been sold 360/67 for TSS/360 to replace 709/1401 (709 tape->tape w/1401 front end doing tape<->unit record).
Pending delivery of 360/67, the 1401 was temporarily replaced by 360/30 (that had 1401 simulation mode). Univ. shutdown datacenter from sat8am until mon 8am and I would have the whole place to myself (although 48hrs w/o sleep could have trouble with Mon. morning classes). They gave me a bunch of manuals and I got to design and implement my own monitor, device drivers, interrupt handlers, error recovery, storage management, etc. and within a few weeks had 2000 card assembler program.
Within a year of taking intro class, I was hired fulltime responsible for OS/360 (TSS/360 never came to production fruition and 360/67 was used as 360/65 w/OS360). Then before I graduate I was 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, 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 be installed, boxes constantly staged in hallways around machine room. Lots of politics between Renton datacenter director and CFO ... who just had a 360/30 up at Boeing field for payroll ... although they enlarged the room to install 360/67 for me to play with CP67/CMS ... when I wasn't busy with other stuff.

Note that student fortran jobs ran less than second on 709 (tape->tape). Initially on OS/360 (360/67 as 360/65), they ran over a minute. One of my 1st tasks responsible for os/360 was installing HASP ... which cut time in half. Then I started doing highly customized OS/360 sysgens ... I would take the STAGE2 deck apart and reorganize the statements of careful placement of datasets and members within PDS datasets to optimize arm seek and (PDS directory multi-trask search lookup). The cut another 2/3rds to 12.9secs/job ... never got less than 709 until installing UofWaterloo WATFOR. Issue was OS/360 services were extremely disk intensive ... like each file open/close involved the loading of a long sequence of 2kbyte SVCLIB members.
This shows up with later decision to add "virtual memory" to all
370s. A decade ago I was asked if I could track down that decision. It
turns out that OS/360 MVT storage management was so horrible that
(application program) "regions" had to be specified four times larger
than normally used ... as a result a typical 1mbyte, 370/165 could
only have four regions (because of intensive disk activity, not
sufficient concurrently executing regions overlapping with enormous
disk access latency, to keep 165 busy and justifying the
machine). Going to virtual memory would allow increasing number of
regions by a factor of four times with little or no resulting paging
(increasing 370/165 busy, throughput and justifying machine). Pieces
of the email exchange in this old archived post
http://www.garlic.com/~lynn/2011d.html#73
Later 370/168 memory increased to 4mbytes that is nearly five times faster (reducing cache miss, memory access latency). Note that the 16x machines were horizontal microcode ... that allowed some overlap in processing. The 370/165 microcode completing a 370 instruction on the avg. of one per 2.1 machine cycles. That microcode was improved for 370/168 and it was completing a 370 instruction on avg of one every 1.6 machine cycles.
While all this was going on in the early 70s, IBM was doing the Future
System project, completely different than 370 and was going to
completely replace all 370s (major motivation was countermeasure to
clone controllers and so complex that would be very difficult to
reverse engineer and clone), and internal politics was shutting down
370 efforts ... the lack of new 370 products during this period is
credited with giving the clone 370 processor makers (like Amdahl)
their market foothold. Turns out it was so complex that even IBM
couldn't do it ... and when FS "imploded" there was mad rush to get
stuff back into the 370 product pipelines ... kicking off the
quick&dirty 3033&3081 efforts in parallel. some more information
http://www.jfsowa.com/computer/memo125.htm
3033 started out mapping 168 logic to 20% faster chips ... they also were able to further optimize the horizontal microcode so that 370 instruction was completing on the avg of one every machine cycle.

trivia: science center came out to install CP67/CMS at the univ (3rd
after CSC itself and MIT Lincoln Labs) ... and I could play with it on
the weekends. I rewrite lots of the code pathlengths, new algorithms,
disk ordered seek queuing, drum page request chaining (multiple
transfers per revolution, improved 2301 from 80/sec to 270/sec),
etc. Initially installed it had 1052 & 2741 support with automagic
terminal identification and switching terminal controller port scanner
type. Univ. had some TTY ASCII terminals and I added ASCII terminal
support (extending automagic terminal id and switching port scanning
type ... trivia, when ascii port scanner for terminal controller
arrived for install, it came in RadioShack box). I then wanted to have
a single dialup number for all terminal
https://en.wikipedia.org/wiki/Line_hunting
didn't quite work since while could switch port scanner type ... they
took short cut and hardwired line speed. This was major Univ
motivation to start clone controller effort ... build a channel
interface board for Interdata/3 programmed to emulate 360 terminal
controller ... with the addition of being able to do dynamic line
speed. Later it is expanded to Interdata/4 for the channel interface
and cluster of Interdata/3s for port scanner. Interdata (and later
Perkin Elmer)
https://en.wikipedia.org/wiki/Interdata
https://en.wikipedia.org/wiki/Perkin-Elmer
start selling it as a clone controller and four of us get written up as responsible for (some portion of) clone controller business.
IBM's FS effort then is supposedly countermeasure for the clone controller business ... but then is responsible for (lack of new IBM 370 products) for clone 370 systems gaining market foothold.
After joining IBM ... one of my hobbies is enhanced production operating system for internal datacenters ... but also allowed to attend user group meetings and visiting customers. The director of one of the largest financial datacenters liked me to come by and talk technology. At some point the IBM branch manager horribly offends the customer ... and retaliation they order an Amdahl system ... lonely Amdahl in large sea of IBM systems (up until then Amdahl had been selling into technical/scientific and univ. market, but had yet to break into the true blue commercial IBM market ... and this would be the 1st). I was then asked to go spend a year on-site at the customer (to help obfuscate reason for ordering the Amdahl). I talk it over with the customer and then declined the offer. I was then told the branch manager is good sailing buddy of IBM CEO ... and if I don't do this, I can forget having a career, promotions, raises, etc.

After graduating, leaving Boeing and joining IBM science center ... the IBM 370/195 group cons me into helping them hyper/multithreading the machine (see patent in the end of acs/360 url/reference) ... 370/195 had 64 instruction pipeline, out-of-order execution ... but conditional branches drained the pipeline ... so many codes ran at only half the 10MIPS throughput. Two instruction streams at 5MIPs each would keep the execution units busy. However, with the decision to make all 370s virtual memory ... it was determined it wasn't worth the effort to try and retrofit virtual memory to 195 ... and all further 195 work was stopped.
In the mid-70s, I started pontificating about the increasing mismatch between processor speed and disk access latency. In the early 80s, I was writing that the disk relative system throughput had declined by an order of magnitude since the s/360s were announced ... i.e. systems got 40-50 times faster but disks only got 3-5 times faster. A disk division executive took exception and assigned the dividion performance group to refute the claim. After a few weeks, they came back and said I had slightly understated the issue. The analysis was then respun and turned into presentation at user group meetings on how to configure disks to improve system throughput (16Aug1984, SHARE 63, B874).
Roll forward to the current century and there are claims that memory is the new disk ... current memory latency when measured in count of current processor cycles is comparable to 60s disk access latency when measured in count of 60s processor cycles. As a result, concurrent execution, multithreading, out-of-order execution, branch prediction, speculative execution, etc ... are comparable to 60s concurrent MVT regions and multitasking for system throughput.

nope, didn't spend a year onsite at customer datacenter ... and it wasn't the first time I would be told I didn't have a career, promotions or raises. In the late 70s and early 80s I would be blamed for online computer conferencing on the internal network (larger than arpanet/internet from just about beginning until sometime mid/late 80s). It really took off spring of 1981 when I distributed trip report of visit to Jim Gray at Tandem ... only about 300 active, but claims upwards of 25,000 reading ... we printed six copies, approx. 300 pages from conferencing along with executive summary and summary of summary packaged in six tandem 3-ring binders and mailed to the executive committee (claim was 5of6 wanted to fire me); from summary of the summary:
• The perception of many technical people in IBM is that the company is rapidly heading for disaster. Furthermore, people fear that this movement will not be appreciated until it begins more directly to affect revenue, at which point recovery may be impossible
• Many technical people are extremely frustrated with their management and with the way things are going in IBM. To an increasing extent, people are reacting to this by leaving IBM Most of the contributors to the present discussion would prefer to stay with IBM and see the problems rectified. However, there is increasing skepticism that correction is possible or likely, given the apparent lack of commitment by management to take action
• There is a widespread perception that IBM management has failed to understand how to manage technical people and high-technology development in an extremely competitive environment.
... took another decade (1981-1992) ... 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.

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 getting started, the board brings in a new CEO and reverses the breakup).

https://history.computer.org/pioneers/bemer.html
Bemer is the inventor of the words "Cobol," and "CODASYL," six ASCII
characters, and the concepts of registry and escape sequences in
character codes. He also invented the term and defined the nature of
the "software factory." At IBM he developed the first load-and-go
system (PRINT I) and also was responsible for the implementation of
the programming system FORTRANSIT, which provided a quick first
compiler for the IBM 650 computer, and was the first programming
language to run both decimal (IBM 650) and binary (IBM 704)
computers. For the support of commercial programming Bemer developed
PRINT I; in the late 1950s he developed XTRAN, a step towards Algol,
and "Commercial Translator," which became a significant input to
Cobol. His major Cobol innovations were the IDENTIFICATION and
ENVIRONMENT divisions, and the PICTURE clause.

88 ACM SIGCOMM had analysis on why window based congestion control was non-stable in bursty, multi-hop internet environment (returning ACKs frequently bunched up and then all arrived in burst, opening transmission for multiple back-to-back packets). Van Jacobson presented slow-start at 88 IETF.

I started HSDT project in early 80s (T1 and faster computer links,
both terrestrial and satellite), was also working with NSF director
and was supposed to get $20M to interconnect the NSF supercomputer
centers. Then congress cuts the budget, some other things happen, and
finally an RFP is release. Preliminary announce (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 ...
... internal IBM politics prevent us from bidding on the RFP. the NSF
director tries to help by writing the company a letter (with support
from other agencies), but that just makes the internal politics worse
(as did claims that what we already had running 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/
A very early HSDT T1 link was between the IBM Los Gatos lab and
Clementi's
https://en.wikipedia.org/wiki/Enrico_Clementi
E&S lab in Kingston ... T1 channel on T3 Collins digital radio from
LSG to roof of bldg 12 on main plant sie, bldg 12 to the San Jose T3
C-band satellite earth station to Kingston, from Kingston T3 earth
station to Clementi's lab, which eventually had a whole boatload of
Floating Point Systems boxes.
https://en.wikipedia.org/wiki/Floating_Point_Systems
In part because of satellite round trip latency ... from nearly the
first, did dynamic adaptive rate-based pacing as part of congestion
control. In the 2nd half of the 80s, was on the XTP (Greg Chesson at
SGI) technical advisory board and wrote rate-based into the XTP
specification.
one of the harder HSDT problems was all internal corporate links had to be encrypted (also lots of gov. politics, especially when links cross national boundaries) ... I really hated what I had to pay for T1 link encryptors and faster encryptors were very hard to find. I got involved in doing link encryptors that could handle at least 3mbyte/sec (not mbits) and cost less than $100 to build. At first corporate crypto group claimed it couldn't be used because it seriously weakened crypto standard. Took me 3months to figure out how to explain to them what was going on ... it was hollow victory ... they then said there was only one organization in the world that could use such crypto ... I could make as many as I wanted, but they all had to be delivered to that organization. It was when I realized that there were three kinds of crypto in the world, 1) the kind they don't care about, 2) the kind you can't do, and 3) the kind you can only do for them.

agency trivia at 7:11 has two 360/65, two 360/67.
three people came out to install CP67 (3rd after CSC & MIT Lincoln
Labs), never replaced OS/360 ... but I got to play with it a lot on my
48hr weekend time. Initially I rewrote a lot of the pathlengths trying
to improve OS/360 in virtual machine. Part of SHARE presentation
detailing some of the CP67 (also references some of the OS/360 work)
http://www.garlic.com/~lynn/94.html#18
OS/360 run on bare machine 322sec, originally under CP67 856sec
(534sec CP67 cpu overhead). A few months playing with CP67 and
rewriting code, OS/360 under CP67 435 secs ... CP67 CPU overhead
113secs ... CP67 processing reduced from 534secs to 113secs.
Local IBM would also suggest changes I might work on, in retrospect some of the suggestions may have originated from gov. agencies ... although I didn't know about it until after graduating and joining IBM. Other work during the period was making multiple CMS running faster, new scheduling and paging algorithms, disk ordered seek queuing to improve disk throughput, page I/O request chaining (from single requests FIFO to chained requests optimized for transfers per revolution, improved 2301 fixed head drum page transfer throughput from 80/sec to around 270/sec under heavy load), etc.
After I graduate and join science center, told about gov. agencies ... in part because they want me to come down and teach (computer & security) classes. One extended class (full large class room in the basement), middle of the afternoon, half the class quietly gets up and walks out. I look quizzically and guy in front row says I can look at it one of two ways, 1) half the class got up to go hear the VP talk in the auditorium or 2) half the class stayed to listen to me (offline he also bragged that they knew where I was every day of my life back to birth, even challenged me to name any date ... strange since I never work for the gov. or had clearance ... I guess they justified because they ran so much of my code ... and it was before the Church Commission). Recently I was reading some books about Lansdale and for some reason there was reference to the VP going across the river to give a talk in the agency auditorium.

about decade later ... first half 80s ... I was asked to help with problem they were having. Agency had large VM3081 systems and was having significant performance problems. The latest VM/SP had exteme unnatural modifications to the multiprocessor support to improve ACP/TPF throughput running on VM/3081 (TPF didn't have multiprocessor support, originally 3081 was going to be multiprocessor only and IBM was afraid that the whole TPF market would migrate to Amdahl ... the latest Amdahl single processor had about same processing as two processor 3081K, eventually IBM ships 3083 for the ACP/TPF market, a 3081 with one of the processors removed) ... but changes for ACP/TPF had degraded throughput for almost all other VM/SP customers running multiprocessor systems. As part of trying to mask the degradation for multiprocessor customers they had fiddled the 3270 terminal support ... which didn't help this customer, since all their terminals were fast glass ascii/teletypes.
Note in the morph of CP67->VM370, a lot of CP67 function/features were dropped and/or greatly simplified. I had spent several years getting CP67 stuff integrated into vm370 (hobby was enhanced production operating systems for internal datacenters). So one of my tweaks was to CMS to chain (simulated 3215) terminal writes in single I/O ... gave about the same results as the 3270 fiddle, but for all kinds of terminals. The other was a "bug" introduced in the CP67->VM370 change. CP67 (& VM37) would make certain scheduling decisions based on device I/O operations (slow speed versus high speed). In CP67 this was based on real device type. In the VM370 morph they changed it to the "virtual" device type. Things were not too bad (as long virtual==real) until 3270 terminals, where the virtual device type was still 3215 simulated on real device type 3270 (and they had significantly different I/O characteristics).

Customers were starting rapid increase in computer uses ... requiring periodic upgrades to more powerful computers ... big inhibitor was having to redo software for each upgrade. For whatever reason, IBM executives were the only ones that managed to force all the different plant managers to toe the compatibility requirement.

... note: 360/65 Multiprocessor was less effective ... not so much because memory bus contention ... but much more because of global kernel locks which serialized much of the operating system execution. Now the 360/67 single processor was basically 360/65 with associative array for virtual memory addressing. However the 360/67 multiprocessor had multi-ported memory so there could possibly have the processors and channel controller accessing memory simultaneously. Also the channel controller allowed all processors to access all channels. The 360/65 (and 370) multiprocessors required each processor to have its own set of channels ... and it somewhat simulated multprocessor I/O with controllers being connected to multiple channels.
... as an aside, Charlie invented the compare&swap instruction ("CAS" mnemonic chosen for Charlie's initials) when he was working on fine grain multiprocessor locking for CP/67 at the science center. Then the initial attempt to get it added to 370 was rebuffed ... the 370 architecture owners (Padegs & Smith) say that the POK favorite son operating system people (OS/360) claimed that the 360 test&set was sufficient for multiprocessor operation (global operating system lock). Advice was to get "CAS" justified for 370, additional uses (other than multiprocessor operation) were needed. Thus was born use for multithreaded applications (like large DBMS implementation) regardless of whether running single processor or multiprocesor (that still appear in principles of operation appendix).
SMP, multiprocessor, tightly-coupled and/or compare&swap posts
http://www.garlic.com/~lynn/subtopic.html#smp
"Usually, the computers were leased not bought, so price comparison is
hard. But a very large System/360 Model 195 was quite fast, could
multiprocess, and had a whopping 4 MB of memory. The cost? Somewhere
between $7 and $25 million in 1971 dollars!"
... snip ...
... 360/195 was single processor only machine ... there weren't 195
multiprocessor, tightly-coupled systems (although 195 MVT supported
multiprogramming). I've periodically mentioned that not long after
joining IBM (at IBM Science Center), the 195 wanted me to help them
"hyper/multi-threading" the 370/195 (aka a 360/195 that added a few of
the new 370 instructions). The end of ACS/360 (IBM executives were
afraid it would advance the state of the art too fast, and IBM would
loose control of the market, Amdahl leaves shortly after ACS/360 was
killed)
https://people.cs.clemson.edu/~mark/acs_end.html
has reference to dual i-stream patents (aka "Sidebar: Multithreading"). At the end of the article also has ACS/360 features that show up more than 20yrs later with ES/9000. The 195 had 64 instruction pipeline and supported out-of-order execution ... but no branch prediction or speculative execution ... as a result conditional branches drained the pipeline and most codes ran at only half 195 rated processing ... going to hyperthreading with two i-streams simulating two processor machine ... each running at half processor rate might keep machine fully utilized (ignoring the fact that 360/65MP MVT was rarely able to run at twice throughput because of the operating system serialized locking, frequently only 1.2 times throughput, NOT two times).
... note that after deciding to add virtual memory to all 370s, it was decided to stop any new work on 195 ... since it would be too hard to retrofit virtual memory to 195 (halting 195 multithreaded work)
trivia: a decade ago, I was asked to try and track down the justification for adding virtual memory to all 370s. Turns out that (basically) MVT storage management was so bad that MVT (concurrently executing) regions had to be specified four times larger than typically used. As a result a normal 1mbyte 370/165 would only have four regions ... not enough to keep 165 processor sufficiently utilized to be justified. Going to virtual memory would allow increasing number of regions by a factor of four times with little or no paging.

Good part of my career was spent being told I didn't have a career, promotions, or raises. After joining IBM, I continued to talk to customers and attend user group meetings ... mid-70s, director of one of the largest financial datacenters (vast sea of true blue computers) liked me to stop by and talk technology. Then the branch manager did something to horribly offended the customer and in retaliation they ordered an Amdahl computer (lonely Amdahl in the vast sea of blue). This was back when Amdahl was selling into technical/scientific/univ. market, but had yet to break into the IBM true-blue commercial market ... and this would be the first. I was then asked to go onsite at the customer for a year (to help obfuscate why they were ordering Amdahl). I talk it over with the customer and then decline the offer. I was then told that the branch manager was good sailing buddy of IBM CEO and if I didn't do this, I could forget having a career, promotion, or raises (wasn't the first, also wasn't the 1st time I would be reminded that in IBM, "business ethics" were an oxymoron).
This was towards the end of the "Future System" effort, from Ferguson
& Morris, "Computer Wars: The Post-IBM World", Time Books, 1993
http://www.amazon.com/Computer-Wars-The-Post-IBM-World/dp/1587981394
.... reference to the "Future System" ...
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.

In the early 80s, I submitted speakup that I was vastly under paid with various supporting documentation. I got a written reply from the head of HR saying after careful review of my complete career, I was being paid just what I was suppose to. I then resubmitted the original, the reply from head of HR, and pointed out I was asked to interview new univ. graduates for a new group that would be working under my technical direction and they were being offered 30% more than I was currently making. I never got a reply, but within a few weeks got a 30% raise, putting me on level with the new hires I was interviewing. Co-workers again reminded me that in IBM, "business ethics" was oxymoron.
I then submitted addition to the "Business Conduct Guidelines" that would upgrade the ethics, but it wasn't accepted. About the same time I was asked to interview for TA to the president of US marketing subsidiary handling clone 370s made on the other side of the pacific. I figured it wouldn't hurt to interview (especially having no career, promotions, or raises at IBM). During the interview there was veiled reference made to documents ("811" nov1978 publication date, had a whole filing cabinet drawer under double lock & key, highest IBM classification, candy stripe, "registered confidential") for next generation 370 (xa/370, 3081). I respond with a reference to my recent submitting ethics upgrade to the IBM "Business Conduct Guidelines" ... and that was the end of the interview. However that wasn't the end of it. A couple years later, the US gov. was suing the parent company for industrial espionage and since I was on the visitor list, I had a 3hr interview with FBI agent. I replayed the interchange ... and suggested somebody in plant site security might have been providing names to recruiter (since security had list of all employees with registered documents for periodic audits).
... also reference to the increasing prevalence of "careerists" and
"bureaucrats" among IBM management:
Management Briefing
Number 1-72: January 18,1972
ZZ04-1312
TO ALL IBM MANAGERS:
Once again, I'm writing you a Management Briefing on the subject of
bureaucracy. Evidently the earlier ones haven't worked. So this time
I'm taking a further step: I'm going directly to the individual
employees in the company. You will be reading this poster and my
comment on it in the forthcoming issue of THINK magazine. But I wanted
each one of you to have an advance copy because rooting out
bureaucracy rests principally with the way each of us runs his own
shop.
We've got to make a dent in this problem. By the time the THINK piece
comes out, I want the correction process already to have begun. And
that job starts with you and with me.

... other trivia: also in the early 80s, I was introduced to John Boyd and would sponsor his briefings at IBM. First time, I tried to do it through plant site employee education ... at first they agreed, but as I provided more information including about prevailing in competitive situations, they changed their mind. They said that IBM spends a large amount of money training managers on how to handle employees ... and exposing regular employees to John Boyd wouldn't be in the best interest of IBM. I should restrict the audience to senior members of competitive analysis departments. First briefing was in bldg28 auditorium open to all (also learned that conference refreshments left for breaks, required guards, because bldg occupants would make them disappear, signs about for conference attendees *ONLY* were ignored).
About the same time I was blamed for the "Tandem Memo" online computer conferencing, six copies of about 300 pages along with "executive summary" and "summary of the summary" were printed and packaged in Tandem 3ring binders and mailed to the IBM executive committee (folklore is 5of6 wanted to fire me). Prominent in the "summary of the summary" were reference to the careerists and bureaucrats were taking down the company.
Note: in 89/90 the commandant of the Marine Corps leverages Boyd for a
"make-over" of the corps ... at a time when IBM was desperately in
need of make-over. It took another decade ("Tandem Memos" to 1992)

up the company (gone behind paywall, mostly free at wayback machine)

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.

from "Tandem Memos" "Summary of the Summary":
• The perception of many technical people in IBM is that the
company is rapidly heading for disaster. Furthermore, people fear that
this movement will not be appreciated until it begins more directly to
affect revenue, at which point recovery may be impossible
• Many technical people are extremely frustrated with their
management and with the way things are going in IBM. To an increasing
extent, people are reacting to this by leaving. IBM Most of the
contributors to the present discussion would prefer to stay with IBM
and see the problems rectified. However, there is increasing
skepticism that correction is possible or likely, given the apparent
lack of commitment by management to take action
• There is a widespread perception that IBM management has failed
to understand how to manage technical people and high-technology
development in an extremely competitive environment.

From: Lynn Wheeler <lynn@garlic.com> Subject: The Supreme Court's History of Protecting the Powerful Date: 17 May 2022 Blog: FacebookThe Supreme Court's History of Protecting the Powerful. Laurence Tribe discusses the leaked Alito draft, the inherent politics of the judicial branch, and how to behave on Twitter.
The Supreme Court Has Never Been Apolitical. Many today fear the court
is becoming just another partisan institution. But, in the past,
justices sought elective office and counseled partisan allies. Some
even coveted the White House themselves.
https://www.politico.com/news/magazine/2022/04/03/the-supreme-court-has-never-been-apolitical-00022482
But maybe that's not a bad thing. You can't address a problem until
you acknowledge it exists. We have pretended over the past 50 years
that the Supreme Court is an apolitical institution. It never really
was, and it isn't today.
In the 1880s, Supreme Court were scammed (by the railroads) to give
corporations "person rights" under the 14th amendment.
https://www.amazon.com/We-Corporations-American-Businesses-Rights-ebook/dp/B01M64LRDJ/
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.
... testimony falsely claiming authors of 14th amendment intended to
include corporations 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.

From: Lynn Wheeler <lynn@garlic.com> Subject: AMEX, First Data, & IBM Date: 18 May 2022 Blog: Facebookrelated recent thread
Trivia: In 1992, AMEX spins off much of its (mainframe) dataprocessing and financial outsourcing (mostly credit card, half of all credit cards in the US, embossing plastic, statements, POS transactions, call centers, as they said "soup to nuts") in the largest IPO up until that time (many of the execs had reported to Gerstner when he was president of AMEX) as "First Data" (after leaving IBM, I do stint as FDC "Chief Scientist"). After the spinoff they acquire significant additional outsourcing (some claim that the spinoff was because some financial institutions viewed AMEX ownership as unfair competition). In 2000, just one datacenter had over 40 max-configured IBM mainframes, constantly being upgraded as new models became available.
15 yrs after being spun off in the largest IPO, KKR does a LBO, reverse IPO of First Data (in the largest LBO up until that time) ... since then KKR sold off First Data to Fiserv.
Trivia: AMEX and KKR were in competition for LBO, reverse IPO of RJR
and KKR wins, KKR ran into problems and hires away AMEX president to
help. Then in 1992, IBM has one of the largest losses in US corporate
history and was being re-org'ed into 13 "baby blues" in preparation
for breaking up the company.

RJR ... gone 404 but lives on at wayback machine

Private equity (PE) firms pervade all aspects of our modern
lives. Unlike other corporations, which generally manufacture
products or provide services, they leverage considerable debt and
other people's money to buy and sell businesses with the sole aim of
earning supersized profits in the shortest time possible. With a
voracious appetite and trillions of dollars at its disposal, the
private equity industry is now buying everything from your opioid

After taking two credit hour intro to fortran/computers, univ. hires me to re-implemented 1401 MPIO on 360/30, I got to design & implement my own monitor, device drivers, interrupt handlers, error recovery, dispatching, storage management, etc. Univ. shutdown datacenter from sat8am to mon8am and I would have the place all to myself for 48hrs straight (although 48hrs w/o sleep made mon morning classes difficult). The univ. had been sold 360/67 for tss/360 to replace 709/1401 (709 tape->tape and 1401 handling tape<->unit record for 709). 360/30 temporarily replaces 1401 ... pending arrival of 360/67. Within year of taking intro class, univ hires me fulltime responsible of os/360 running on 360/67 (tss/360 never came to production fruition and 360/67 was run as 360/65 with os/360).
Three people then from IBM science center to install cp67/cms (3rd
installation after cambridge itself and Lincoln Labs). I get to play
with it in my 48hr weekend dedicated window. I initially rewrite a lot
of pathlengths for OS/360 running in CP67 virtual machine. Part
of presentation I made at share after a few months of rewriting CP67
http://www.garlic.com/~lynn/94.html#18
OS/360 (benchmark) run on bare machine 322sec, originally under CP67
856sec (534sec CP67 cpu overhead). A few months playing with CP67 and
rewriting code, OS/360 under CP67 435 secs ... CP67 CPU overhead
113secs ... CP67 processing reduced from 534secs to 113secs.
I then start doing dynamic adaptive resource management, (global LRU) page replacement algorithms, page I/O optimization, dynamic working set, ordered arm seek queuing, etc. This was about the same time there were some academic papers in the ACM on "local lru" page replacement algorithm and working set page thrashing controls.
IBM (cambridge science center) picks most of my stuff and ships in CP67. Later in the early 70s, the IBM Grenoble Science Center implements the ACM academic "local LRU" and working set stuff in CP67. Cambridge at the time was running 80 CMS users on 768kbyte (104 pageable pages after fixed memory requirements). Grenoble was running 35 CMS users on 1mbyte (156 pagealbe pages after fixed memory requirements). The two systems had similar CMS workloads, throughput and response ... but my implementation was doing it with twice the users and 2/3rds paging space.
At 14-16Dec81 ACM SIGOPS ... Jim Gray asks me if I can help a co-worker of his at Tandem with his Stanford PHD ... involving global LRU page replacement algorithms. The "local LRU" forces from the 60s were heavily lobbying Stanford to not award a PHD in global LRU ... and Jim knew of my work in the 60s and I had apples-to-apples comparisons with Cambridge CP67 (running global LRU) and Grenoble CP67 (running local LRU). I pull out the information, but when I go to send it, IBM management says that I can't (even though it involved work I had done before joining IBM). It takes almost a year (19Oct1982) before I'm allowed to send the information.
Note in the late 70s & early 80s, I had been blamed for online computer communication on the internal network ... and spring of 1981, it really took off after I distributed a trip report visiting Jim at Tandem ... only about 300 participated, but claims that upwards of 25,000 were reading (folklore is when corporate executive committee was told, 5of6 wanted to fire me). In any case, I hoped that IBM management figuring that they it was part of punishing me for online stuff ... and not taking part in the academic global/local dispute and Stanford awarding a global LRU PHD.

... I also accumulated several papers ready for publication ... but IBM management was constantly saying that they weren't ready to be sent off (analogous to not being send off description of work I had done as undergraduate before joining IBM, couldn't be sent to stanford in the global/local LRU dispute). The senior local plant site tech editor attempted to tweak them to IBM management satisfaction ... but never happened. Several years later when he was about to retire and cleaning out his files, he forwarded his copies to me with note about having never encountered such IBM management behavior
... other trivia: also in the early 80s, we had done a system modification that could efficiently capture the record number for every disk I/O (paging, file, etc) and used it for a number of different systems doing wide variety of different computing work. One of the things it was used for was a I/O cache simulator ... which I claimed validated global LRU beating local LRU. Given a fixed amount of electronic memory ... a global system cache always beat splitting the electronic memory into channel level caches, disk controller level caches, and/or disk level caches (the caveat was where technology restricted the total amount of memory that could be addressed ... so that the total amount of memory in disk level caches could greatly exceed the amount of memory in a global system cache).
... in the 60s, IBM had 2301 & 2303 fixed head (per track) "drums" that could be used for paging &/or files ... so that there was no head movement access, just rotational delay. The followon was 2305 in the 70s, which was fixed head "disk" ... again no head movement delay, just rotational delay. By 1980, there was no followon product. IBM then contracted with vendor for what they called "1655", electronic disks that would emulate a 2305 ... but had no rotational delay. One of the issue was that while IBM had fixed-block disks, the company favorite son batch operating system never supported anything other than CKD DASD ... so for their use it had to simulate an existing CKD 2305 running over 1.5mbyte I/O channels. However for other IBM systems that supported FBA ... 1655s could be configured as fixed-block disk running on 3mbyte/sec I/O channels ... similar to SSD ... but had standard electronic memory that wasn't persistent w/o power.

From: Lynn Wheeler <lynn@garlic.com> Subject: 360&370 I/O Channels Date: 21 May 2022 Blog: Facebookup through m50, 360s had integrated channels ... i.e. processor unit had (at least) two sets of microcode ... one that implemented 360 instruction set and the other implemented channels. 360/60 & 360/70 originally announced with 1mic memory ... replaced with 360/65 and 360/75 than had 750ns memory. Also had 2860 (selector) and 2670 (multiplexor) external channels. 2880 block mux channels came along with "set sector" channel command ... 3330 & 2305 dasd could specify disconnect from channel until disks rotated around to specified position (to request channel reconnect, that would involve data transfer).
370 up through 158 also had integrated channels ... i.e. 158-3 processor unit had two sets of microcode ... while 370/165 & 370/168 had external channels.
In the 1st half of the 70s, IBM had the "Future System" project that
was going to completely replace 370 (and completely different)
... during FS, internal politics was shutting down 370 efforts (lack
of new 370 during FS is credited with giving clone 370 makers their
market foothold). FS was suppose to be so complex as a countermeasure
to clone controller makers ... they wouldn't be able to keep up
... but turns out it was also too complex for IBM to do (one of the
last nails in FS coffin was study by the IBM Houston Science Center
that 370/195 applications redone for FS machine made out of the
fastest available hardware, would have throughput of 370/145 ... about
30 times slowdown). All during FS, I continued to work on 360&370 and
would periodically ridicule what they were doing (which was exactly
career enhancing activity). After FS implodes, there was mad rush to
get stuff back into the 370 product pipelines, including kicking off
quick&dirty 303x and 3081 in parallel. some FS details
http://www.jfsowa.com/computer/memo125.htm
3033 started out remapping 168-3 logic to 20% faster chips. For the external channels (303x "channel director"), they took an 158-3 engine with just the integrated channel microcode. A 3031 was a 158-3 engine with just the 370 instruction microcode and a 2nd 158-3 engine with just the integrated channel microcode (for 303x "channel director"). A 3032 was a 168-3 redone to use 303x "channel director" (158-3 engines with just the integrated channel microcode).
When I first transferred from IBM cambridge science center to IBM San Jose Research, I got to wander around local IBM and customer datacenters including bldg14 (disk engineering) and bldg15 (disk product test) across the street. They were doing preschedule, around the clock, stand-alone mainframe testing. They said they had recently tried to use MVS, but it had 15min mean-time-between-failure (requiring manual re-ipl) in that environment. I offered to rewrite I/O supervisor to make it bullet-proof and never fail so that they could do any amount of on-demand, concurrent testing ... greatly improving productivity.
Bldg15 tended to get very early engineering processing models for DASD testing ... including 3033 (with three channel directors, i.e. 158-3 integrated channel microcode supported up to six channels, so needed three for 16 channels) and 4341. The DASD testing only used a percent or two of 3033 processing ... so we found spare 3830 controller an couple strings of 3330s and put up our own online service (including running 3270 coax under the street to my bldg28 office). The 303x channel directors were still having some teething problems ... and would periodically require opening the doors and restarting the box. However, we discovered if you executed HCH (halt channel) for all six channels ... the box would automagically re-IMPL (w/o requiring somebody to manually do it). Later when we got some early 3274 controllers (which had similar problems requiring manual restart) ... we found if we quickly executed HDV/CLRIO instruction sequence for every 3274 subchannel address, it would also automagically re-IMPL.
Not without downsides; engineers would kneejerk complain that I was responsible for problems and I would have to spend increasing amount of time playing disk engineer and diagnosing hardware problems ... including getting into arguments that some of the stuff they were trying to do with development 3880 controllers were violating channel architecture (after escalating to conference call with POK channel engineers, disk engineers were demanding that I participate on future meetings and conference calls involve channel architecture). Another problem was I wrote internal IBM paper on the work ... and happened to mention the MVS 15min MTBF ... which brings down the wrath of the MVS group on my head (including claims of unsuccessful effort to separate me from IBM).

trivia: in the mid-70s, I started pontificating that DASD throughput wasn't keeping up with system performance. In the early 80s, wrote a tome that relative DASD throughput had declined by order of magnitude since the start of 360s (disks got 3-5 times faster, systems got 40-50 times faster). Some disk division executive took exception to my claims and assigned the division performance group to refute the claims. After a few weeks, they came back and said that I had slightly understated the problem. The performance group then respun the analysis for a (customer user group) SHARE presentation (16Aug1984, SHARE 63, B874) about configuring DASD for improved system throughput.
more trivia: 1980, STL (since renamed SVL) was bursting at the seams and were moving 300 from the IMS group to offsite bldg, with dataprocessing service back to STL datacenter. They had tried remote "3270" but found the human factors totally unacceptable. I then get con'ed until doing channel-extender support, placing channel attached 3270 controllers at offsite bldg ... and no perceptible difference for offsite and onsite (STL) 3270 human factors. The hardware vendor then tries to get IBM to release my support ... but there is group in POK playing with some serial stuff and are afraid if my stuff was in the market, it would make it harder to justify releasing their stuff ... and get it veto'd. Later in 1988, the branch asks if I can help LLNL (national lab) get some serial stuff they are playing with, standardized. It quickly becomes FCS (including some stuff I had done in 1980), starting at 1gbit full-duplex, 2gbit/sec aggregate, i.e. 200mbyte/sec. Then in 1990, the POK people get their stuff released wtih ES/9000 as ESCON (when it is already obsolete, 17mbytes/sec). Later some POK engineers become involved in FCS and define a heavy-weight protocol (that drastically reduces the standard throughput), which eventually ships as FICON.
Most recent published benchmark I can find, z196 "peak I/O" getting 2M IOPS needing 104 FICONS (running over 104 FCS). About the same time FCS announced for E5-2600 blades claiming over million IOPS (two such FCS having higher throughput than 104 FICONS running over 104 FCS). Other trivia: mainframe CKD DASD haven't been made for decades, being simulated on industry standard fixed-block disks ... aka, mainframe IOPS benchmarks not only the FICON overhead, but also CKD simulation overhead.

affect revenue, at which point recovery may be impossible
• Many technical people are extremely frustrated with their management

people are reacting to this by leaving IBM Most of the contributors
to the present discussion would prefer to stay with IBM and see the

"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."

trivia: I continued to work on 360&370 stuff all during FS (was
completely different from 370 and was suppose to completely replace
370; during FS, internal politics was shutting down 370 activity,
which was credited with giving the clone 370 makers their market
foothold) and would periodically ridicule what they were doing (which
wasn't particularly career enhancing activity). I was also blamed for
online computer conferencing (precursor to modern social media) in the
late 70s and early 80s ... it really took off spring of 1981 after I
distributed trip report of visit to Jim Gray at Tandem. Only about 300
participated, but claims of upwards of 25,000 were reading. Eventually
printed six copies of 300 conference pages along with executive
summary and summary of the summary, packaged in Tandem 3-ring binders
and set to the corporate executive committee (folklore is 5of6 wanted
to fire me). From summary of the summary:
• The perception of many technical people in IBM is that the company is
rapidly heading for disaster. Furthermore, people fear that this
movement will not be appreciated until it begins more directly to
affect revenue, at which point recovery may be impossible
• Many technical people are extremely frustrated with their management
and with the way things are going in IBM. To an increasing extent,
people are reacting to this by leaving IBM Most of the contributors to
the present discussion would prefer to stay with IBM and see the
problems rectified. However, there is increasing skepticism that
correction is possible or likely, given the apparent lack of
commitment by management to take action
• There is a widespread perception that IBM management has failed to
understand how to manage technical people and high-technology
development in an extremely competitive environment.

if 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

CEO and reverses the breakup ... new CEO also used some of the same

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.

... some more on careerists and bureaucrats (from my comments
upthread) ... I had been introduced to John Boyd in the early 80s and
would sponsor his briefings at IBM. In one of his briefings, he noted
that former military officers were starting to destroy US corporate
culture with their ingrained, rigid, top-down, command&control
(theoretically only those at the very top were qualified to make
decisions). However, that was about the same time that articles were
starting to appear that MBAs were destroying US corporations with
their myopic focus on quarterly results (some amount of that was
discussed in "Tandem Memos" ... part of the internal online computer
conferencing that I was blamed for in the late 70s and early 80s). The

barriers to competition -- including barriers to entry -- that help

In 89/90, the commandant of the marine corps leverages Boyd for a make-over of the corps (at a time when IBM was desperately in need of a make-over ... as mentioned upthread, in 92, IBM has one of the largest losses in US corporate history and was being reorganized into the 13 "baby blues" in preparation for breakup of the company). We had already left IBM, but were contacted from the bowels of Armonk about helping with the breakup of the company (new CEO was brought in and reversed the breakup before we got started). Along the way we were getting email from former IBM colleagues about top executives weren't running the business but myopically focused on moving expenses from the following year to the current year. We ask our contact from the bowels of Armonk about it. He says that the current year was in the red and they won't get a bonus ... but if they could move sufficient expenses from the following year into the current year, even nudging it slightly into the black ... the way the executive bonus plan was written, they would get a bonus more than twice as large as any previous bonus (aka effectively reward for taking the company into the red).
... another contributing factor that I periodically mention is IBM mainframe hardware use to be the mainstay of IBM revenue ... but that was quickly dropping with the death grip stranglehold that the communication group had on mainframe datacenters with their corporate strategic ownership of everything that crossed datacenter walls ... and fiercely fighting off client/server and distributed computing (trying to preserve their dumb terminal paradigm). Late 80s a GPD/Adstar senior disk engineer got a talk scheduled at internal, annual, world-wide, communication group conference ... supposedly on 3174 performance, but opens the talk with statement that the communication group was going to be responsible for the demise of the disk division. They were seeing a drop in disk sales with customer data fleeing datacenters to more distributed computing friendly platforms. They had come up with number of solutions ... but they were constantly being vetoed by the communication group (with their corporate strategic ownership of everything that crossed datacenter walls). Trying to work around the corporate politics, the senior GPD/Adstar executive of software is investing in distributed computing startups that would use IBM disks ... he also asks us to visit his investments and provide any help we could.

During Future System in the 1st part of 70s (was completely different than 370 and was going to completely replace 370) internal politics during the period was shutting down 370 efforts, and the lack of new 370 is credited with giving 370 clone makers their market foothold. When FS implodes there was a mad rush to get stuff back into the 370 product pipeline ... including kicking off quick&dirty 3033&3081 in parrallel. some more info

The head of POK was also convinced corporate to kill vm370 product, shutdown the development group and transfer all the people to POK (for MVS/XA) or otherwise (claimed that) MVS/XA wouldn't be able to ship on time. Part of the shutdown was trashing ongoing new vm370 stuff ... including significantly extensions to CMS OS/simulation. Endicott eventually managed to acquire the VM370 product mission, but had to reconstitute development group from scratch.
A decade ago, a customer asked me if I could track down why all 370s
were made virtual memory. I eventually found somebody that worked for
the executive. Basically MVT storage management was so bad that
regions had to be four times larger than normally used ... so a
typical 1mbyte 370/165 would only have four regions ... insufficient
workload throughput to justify 165. Going to virtual memory allowed to
increase the number of MVT regions by a factor of four ... with little
or no paging. Old archive post with some of the email exchange:
http://www.garlic.com/~lynn/2011d.html#73
includes mentioning dropping in on Ludlow doing the original VS2 prototype (aka VS2/SVS) on 360/67 ... very analogous to running MVT in a CP67 16mbyte virtual machine ... except a little code was moved into MVT that built 16mbyte virtual address space tables and some simple paging. Biggest code was EXCP/SVC0 taking channel programs from applications and executing them. Now all (application) channel programs had virtual address and channels required real addresses. Basically CP67 CCWTRANS (that created copy/shadow channel programs with real addresses, for execution) crafted into EXCP/SVC0.

Later for VS2/MVS, each "region" was given its own 16mbyte address space, however because OS/360 was heavily pointer-passing API, an 8mbyte image of the MVS kernel was mapped into each address space (so each MVS image could directly access calling application's adresses) ... reducing application space to 8mbyte. However, OS/360 subsystems were also put in their own 16mbyte address space. To allow subsystems to address calling application addresses, the 1mbyte "common segment" was created in every address space for application to pass parameters (reducing application available space by another mebyte to 7mbytes). However that requirement was somewhat proportional to number of subsystems and concurrently executing application ... by 3033 it had become "CSA" (common system area) and was typically 5-6mbytes (leaving only 2-3mbytes available for applications) and threatening to becomes 8mbytes (leaving zero bytes for applications).
IBM Burlington had a major chip design program implemented in Fortran that was 7mbytes .... which was run on several carefully crafted dedicated MVS systems that only had a single mbyte CSA ... and they were also constrantly fighting the 7mbyte limit any time changes and/or enhancements were made. About the same time there were an explosion in internal VM/4341s being installed out in departmental area (so many departmental conference rooms were being used for 4341, that conference rooms were becoming scarce resource).
At the same time many machine rooms had reached physical capacity and lots of IBM was looking at how to move applications off the big mainframe to the departmental machines. Los Gatos VLSI lab found that many applications on the main plant site required MVS features not supported by CMS. They did some work and found that 12k bytes of additional OS Simulation ... they were able to move most major applications. Then OS Simulation enhancements was even offered to IBM Burlington, that they could move all the large dedicated mainframe off MVS to VM370/CMS and eliminate their 7mbyte limit problem for the major chip design program (that with a few additional tweaks, CMS OS simulation was doing everything they needed from MVS ... and CMS would only take a couple hundred k-bytes, rather than 9mbytes).

trivia: POK was planning on not telling the VM370 group until the very last minute, that VM370 was being killed and they were all being moved to POK (to minimize the number that might escape). However, the information managed to leak early and numerous managed to escape (DEC VMS was in its infancy and there was joke that head of POK was major contributor to VAX/VMS). There was then a witch hunt to track down the leak ... fortunately nobody gave me up.

a little topic drift ... Endicott (may1975) had con'ed into working
with them on ECPS microcode assist (for virgil/tully aka 138/148)
... including the initial analysis of what would be dropped into
microcode. I was told that 370->microcode would drop in on about
byte-for-byte basis and there was 6kbytes available ... and I needed
to identify the 6kbytes highest executed VM370 code. Old archived post
with initial analysis (6kbytes vm370 kernel accounted for 79.55% of
vm370 kernel cpu and would run ten times faster in microcode)
http://www.garlic.com/~lynn/94.html#21
Endicott then tried to get corporate approval to ship vm370 in every 138/148 made (sort of like later PR/SM-LPARS) ... but since POK was in the process of convincing corporate to kill vm370 product ... they couldn't get approval.
Early 80s, I get approval to give presentation on how ECPS was done, at local monthly BAYBUNCH user group meetings. After meetings, we usually adjorned to local silicon valley watering holes ... and the Amdahl people grilled me for more on ECPS. They said that they were in process of implementing HYPERVISOR in Amdahl "MACROCODE" ... a 370-like instruction set that ran in microcode mode. MACROCODE was originally developed to greatly simplify and cut the time to respond to the plethora of trivial microcode changes that IBM had started doing for 3033 (which were required by IBM operating systems). For high-end machines, microcode was "horizontal" which was very complex and time-consuming to program. While Amdahl was able to ship "HYPERVISOR" in the early 80s ... it took until 1988 for IBM to respond with PR/SM & LPAR for 3090.
Other trivia: comment mentioned upthread, POK had killed the VM370 development group and moved the people to POK ... there was an "internal only" virtual machine facility (VMTOOL) done supporting MVS/XA development with SIE microcode assist (similar to ECPS) ... it was never intended for performance and/or production use. Later when customers weren't converting to MVS/XA as planned ... and Amdahl customers were enjoying HYPERVISOR being able to run both MVS and MVS/XA as converstion aid ... SIE microcode and VMTOOL (as VM/MA & VM/SF) were made available on 3081. One of the SIE performance issues (never intended for production use) was 3081 didn't have the microcode space ... and SIE microcode had to be "paged" in and out.
Old archived email from trout (ie. 3090) processor engineer ... was
that they were at least doing 3090 SIE for production performance (and
didn't have to be paged in&out).

trivia: about same time as ECPS ... got involved in a project to do
16-processor SMP system ... and we sucked the 3033 processor engineers
into working on it in their spare time (lot more interesting that Q&D
remapping 168-3 logic to 20% faster chips). Everybody thought it was
really great until somebody told the head of POK that it could be
decades before the POK favorite son operating system (MVS) had
(effective) 16-way support. He then invites some of us to never visit
POK again and directs the 3033 processor engineers to solely focus on
the 3033 (once the 3033 is out the door, they start on trout,
i.e. 3090 ... I would periodically sneak back into POK). Pure aside,
1st 16-processor to ship is z900 after turn of the century, over 20yrs
later. also see FS about Q&D 3033&3081

trivia: I had taken 2 credit hour intro to FORTRAN/computers ... at the end of semester got a student programming job to rewrite 1401 MPIO for 360/30. The univ had been sold 360/67 for TSS/360 to replace 709/1401 (709 tape->tape w/1401 front end doing tape<->unit record). Pending delivery of 360/67, the 1401 was temporarily replaced by 360/30 (that had 1401 simulation mode). Univ. shutdown datacenter from sat8am until mon 8am and I would have the whole place to myself (although 48hrs w/o sleep could have trouble with Mon. morning classes). They gave me a bunch of manuals and I got to design and implement my own monitor, device drivers, interrupt handlers, error recovery, storage management, etc. and within a few weeks had 2000 card assembler program. 360/30 ran PCP release 6 (OS/360 assembler option generated BPS or OS/360 mode, took 30mins elapsed time to assemble BPS mode, 60mins to assemble OS/360 mode ... about 5mins/DCB macro).
Within a year of taking intro class, I was hired fulltime responsible for OS/360 (TSS/360 never came to production fruition and 360/67 was used as 360/65 w/OS360) and I continue to have my dedicated 48hr weekend time. My first 360 SYSGEN was MFT release 9.5. Student FORTRAN ran under second with 709 IBSYS tape->tape. Initially in 360/65 (mode) they ran over a minute. I install HASP cutting run time in half. Then for Release 11 SYSGEN ... I start reorder the SYSGEN cards for careful ordering of datasets and PDS members (to optimize arm seek and pds directory multi-track search). By the time I do Release 14 SYSGEN, I've gotten the elapsed time down to 12.9sec (approx three times faster than standard SYSGENed system w/HASP). My first MVT SYSGEN is release 15/16 (15 slips and released as combined 15&16) and then release 18. Note student jobs never beat 709 time until I installed Univ. of Waterloo WATFOR.

lot of the code. Tests running MFT14 student benchmark, 322sec bare
machine, 856sec in virtual machine (534sec CP67 CPU). After a few

Then before I graduate I was 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, including offering services to non-Boeing entities). I thot Renton datacenter was possibly largest in the world (couple hundred million in 360s), 360/65s were arriving faster than they could be installed, boxes constantly staged in hallways around machine room. Lots of politics between Renton datacenter director and CFO ... who just had a 360/30 up at Boeing field for payroll ... although they enlarged the room to install 360/67 for me to play with CP67/CMS ... when I wasn't busy with other stuff.

Some of the MIT/7094 CTSS people
https://en.wikipedia.org/wiki/Compatible_Time-Sharing_System
went to the 5th flr, project mac, and MULTICS.
https://en.wikipedia.org/wiki/Multics
Others went to the 4th flr, IBM Cambridge Science Center, did virtual
machine CP40/CMS (on 360/40 with hardware mods for virtual memory,
morphs into CP67/CMS when 360/67 standard with virtual memory becomes
available, precursor to vm370), online and performance apps, CTSS
RUNOFF redid for CMS as SCRIPT, GML invented at science center in 1969
(and GML tag processing added to SCRIPT, a decade later GML morphs
into ISO SGML and after another decade morphs into HTML at CERN),
networking, etc.

The science center had wanted a 360/50 to add virtual memory hardware
for their virtual machine project ... but all the spare 360/50s
were going to FAA ATC, The Brawl in IBM 1964
https://www.amazon.com/Brawl-IBM-1964-Joseph-Fox/dp/1456525514
and the science center had to settle for 360/40
http://www.leeandmelindavarian.com/Melinda#VMHist
The IBM Boston Programming Center was on the 3rd floor and had done
CPS
https://en.wikipedia.org/wiki/Conversational_Programming_System
and CPS microcode assist for 360/50 ... although lots was
subcontracted out to Allen-Babcock
http://www.bitsavers.org/pdf/allen-babcock/cps/
http://www.bitsavers.org/pdf/allen-babcock/cps/CPS_Progress_Report_may66.pdf
Some of the CP67/CMS people split off from the science center and take over IBM/BPC on the 3rd floor to do VM370 (along the way CPS is ported to CMS). When they outgrow the 3rd flr, they move out to empty IBM SBC building at burlington mall (before being shutdown and moved to POK to work on MVS/XA).

One of the first was also distributed development project between the cambridge science center (utilizing the genesis of the IBM internal network done by one of the other people at the science center) and endicott to implement 370 virtual memory architecture virtual machines running under CP67 running on 360/67. My enhanced CP67L actually ran on the real 360/67, CP67H ran in a 360/67 virtual machine and provided both 360 and 370 virtual machines. Then a modified CP67I (modified for 370 virtual memory architecture) ran in a 370 virtual machine (under CP67H). This was regularly running production a year before the first engineering 370 with virtual memory support was operational (370/145).
Note the extra level was for security because there were professors, staff and students from Boston area univ. also using the science center CP67/CMS ... and wanted to make sure there was no exposure to 370 virtual memory ... which hadn't been announced. CP67I was also used as initial test case for the first virtual memory 370(/145) in Endicott. Some engineers from San Jose then came out and added 3330 and 2305 device support to CP67I for CP67SJ ... for a long time CP67SJ was the primary operating system running internal on virtual memory 370 processors.
Part of the issue was in the morph from CP67->VM370 a lot of feature, function, and performance was dropped and/or greatly simplified. When I first started moving from CP67 to VM370, my automated benchmarking consistently would crash VM370 ... and some of the first CP67 changes migrated to VM370 was the CP67 kernel integrity and serialization (in order to get VM370 to consistently get through the benchmarks w/o crashing).

From: Lynn Wheeler <lynn@garlic.com> Subject: VM/370 Turns 50 2Aug2022 Date: 25 May 2022 Blog: FacebookOne of the early "cloud" similarities was the early work done on CP67 (precursor to VM370, by the science center and then the two commercial CP67 spin-offs from the science center). Back in the 60s, machines were leased/rented and charges were based on the "system meter" that ran whenever (any) processor and/or channel was "busy". Moving to 7x24 operation there was lots of work to allow dark room, unattended operation (including things like automatic re-ipl after any sort of problem) as well as letting the "system meter" stop whenever the system was idle. This included special terminal channel programs that would allow the channel to stop, but immediately wake up whenever characters were arriving. Trivia: everything (processors & channels) had to be quiet for at least 400ms before the "system meter" stopped.
Note: long after IBM had switched from system leased/rental to purchase, MVS still had a 400ms timer-event guaranteeing that the system meter never stopped. Also 1974, CERN presented at SHARE a report on comparison of VM370/CMS with MVS/TSO ... copies of the report was freely available at SHARE ... but inside IBM they were classified "IBM Confidential Restricted" (2nd highest security classification) available on a need to know basis only (after FS implodes and mad rush to get stuff back into 370 product pipelines, contributing to head of POK getting corporate to kill VM370 product, shutdown the development group and transfer all the people to POK to work on MVS/XA ... Endicott eventually manages to acquire the VM370 product mission, but had to reconstitute development group from scratch).
Equivalent in modern cloud megadatacenters is power&cooling costs ... in part because system and manual operating costs have so drastically been reduced. A large cloud operations will have a dozen or more megadatacenters around the world, each staffed with 80-120 people and having half million or more systems (upwards of 10,000 systems/staff member). More recent system cost comparison is max configured z196 rated at 50BIPS processing (based on industry benchmark where number of iterations compared to 370/158 assumed to be one MIPS processor) at $30M (or $600,000/BIPS). The equivalent megadatacenter system is E5-2600 blade rated at 500BIPS (same industry benchmark with no. iterations compared to 370/158) and IBM base list price of $1815 ($3.63/BIPS). However, for a couple decades large cloud operations have been claiming they assemble their own systems at 1/3rd the cost of brand name systems ($1.21/BIPS). Note: IBM unloaded their blade/server business not long after press by server chip makers were claiming they were shipping half their product directly to cloud operations.
In any case, cloud operations have increasingly pressured chip makers to improve computing power efficiency, as well as power dropping to zero when systems are idle (but immediately available ondemand).

virtual memory provided analogy fetch protect
... programs/instructions couldn't access storage they weren't
authorized for ... slight drift
http://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml
Lots of CMS was read-only code&data ... so it was possible to have "shared pages" ... i.e. a single copy of the page in real storage ... instead of a unique copy for each user virtual address space. In theory, within a virtual address space, a CMS user could do anything it wanted to ... including fiddling the storage keys. CP67 had a hack for shared/protected pages ... that prevented a CMS user for changing keys on protected pages as well (simulating virtual address space had shared protected pages), prevented from changing the PSW key protect field (they could "execute" the instructions ... but the CP67 privileged instruction simulation would restrict emulation of those operations for address spaces that had shared, protected pages). The downside of the storage protect hack was standard 360 had non-zero 1-15 unique "protected" ids and the PSW key was either zero (which provided access to everything) or a non-zero key that provided access to just storage with matching key ... so CP67 had to give all shared/protected pages a (common) non-zero key and guarantee real PSW had both a non-zero key and a non-matching key.
A decade ago, customer asked if I could track down IBM decision to
make all 370s "virtual memory" (after initially having been no virtual
memory). Basically MVT storage management was so bad, that execution
regions had to be four times larger than actually used, so a regular
1mbyte 370/165 system would only have four regions ... insufficient
multiprogramming throughput/utilization to justify the
machine. Virtual memory would allow the number of regions to be
increased by a factor of four times, with little or no paging ... old
archive post with some of the email exchange
http://www.garlic.com/~lynn/2011d.html#73
Part of the full 370 virtual memory architecture included "segment protect" (a bit in the segment table entry that wouldn't allow storage alteration for virtual pages in protected segment) ... a whole segment could be the shared in multiple address spaces ... with some allowed to alter the protected storage and others prevented from altering protected storage. However, 370/165 engineers escalated that unless they were allowed to drop parts of the full 370 virtual memory architecture (including segment protection) ... the 370 virtual memory announce would have to slip by six months. Eventually it was decided to go with the 370/165 architecture subset ... and all the other models would have to drop what they had already implemented (and any software that would use the dropped features would have to be redone). This "hurt" VM370/CMS because they couldn't use "segment protect" for CMS shared pages ... and would have to drop back to the CP67 storage key shared page hack. This eventual hurt CMS performance because the VM370 microcode assist (numerous privileged instructions directly supporting VM370 mode, couldn't be used).
For VM370 Release 3, they announced a HACK that would allow cms users to execute with the VM370 microcode assist ... where CMS address space could modify shared protected pages while executing ... but VM370 kernel would scan all protected pages for having been "changed" ... if it found any changed pages, it would regress the modified virtual page to an unmodified version on disk (before switching CMS user). The reduction in privileged instruction simulation (by using VM370 microcode assist) was greater than the overhead scanning the CMS 16 shared/protected pages for changes everytime switched the CMS user executing. The problem was was that also introduced in VM370 Release 3 ... there was a big increase in the number of CMS shared/protected pages which inverted the trade-off (the release 3 change to allow use of VM370 microcode assist not coordinated with the big increase in the number of CMS shared/protected that needed to be scanned on every task switch). Further aggravating the situation was many 370/168 customers had bought the VM370 microcode assist (based on vm370 release announce using the microcode assist) and marketing claimed that it wasn't possible to reverse to not using VM370 microcode assist (even though the benefit was inverted because of the increase in number of shared/protected pages that had to be constantly scanned). The "problem" was further aggravated in VM370 Release 4 with the introduction of multiprocessor support (one of the things dropped in the original morph of CP67->VM370). The Release 3 change to allow changing shared/protected shared pages were dependent on exclusive use by task during its execution.
With Release 4 SMP introduction there could now be two concurrently CMS users executing. In order to meet the "exclusive" requirement, there now had to be two processor-specific copies of every shared page ... not only would all (processor-specific) shared/page on task switch from a user ... but before a user (with shared/protected pages) starts executing, their address tables had to be updated to point to the processor-specific copy of shared/protected pages (huge additional overhead, further aggravating the CPU penalty being paid for just enabling CMS users to execute with VM370 microcode assist ... and couldn't reverse it because IBM had convinced some 370/168 vm370 customers to buy the VM370 microcode assist).

other trivia: one of my hobbies after joining IBM was enhanced production operating systems for internal datacenters and HONE was long time customer. HONE had originally started out after the 23Jun1969 unbundling announcement, starting to charge for (application) software, maintenance, SE services, etc. The problem was part of SE education was sort of apprentice as part of multi-SE group onsite at customers ... and they couldn't figure out how not to charge for apprentice SEs at customer site. HONE was originally created for that part of training ... allowing branch SEs to practice with guest operating systems in CP67 virtual machines. The science center had also ported APL\360 to CMS as CMS\APL (redoing storage management for large demand paged, virtual address spaces and adding system services API ... including things like file I/O) and HONE started offering CMS\APL-based sales&marketing support applications. The sales&marketing applications eventually came to dominate all HONE use (and the original HONE guest operating system purpose evaporated).
I eventually got around to upgrading VM370 with lots of my CP67 (that ran on 360/67 and CP67I&CP67SJ that ran on 370) enhancements (including lots of integrity and serialization eliminating many system crashes) for my internal "CSC/VM" (vm370 release 2) ... including upgrading HONE datacenters (that had previously started migration to VM370). I continue with CSC/VM on release 3 platform ... that used the CP/67 process for shared/protected shared pages (mostly HONE ran APL that had another couple score shared/protected pages ... which would have further grossly inflated the official release3 mechanism for shared/protected pages. US HONE datacenters had been consolidated in Palo Alto (facebook trivia: when facebook 1st moves into silicon valley, it was new bldg built next door to the former HONE datacenter).
US HONE VM systems were further enhanced to max number of 370 processors in single system image, loosely-coupled configuration (with complex-wide load-balancing and fall-over; every 3330 string w/string switch and every string switch, connected to two 3830 controllers with 4-channel interfaces ... 8 channels & systems total for every 3330). I then moved a lot of (cp67) multiprocessor support to release3-based CSC/VM ... and HONE added a 2nd processor to each system (for 16processors total, I believe at the time, the largest single-system image complex in the world).
Eventually in the 80s ... a page protect bit was added to the mainframe architecture ... allowing access but not store/changing data for all address spaces ... wasn't exactly like the original 370 architecture ... where each address space had private segment address space tables and some address spaces could be allow r/w access to all pages in a shared segment while other address spaces would be restricted to r/o access. Trivia: this was somewhat simulated in the original RDBMS/relational System/R implementation (where server/controller address space had r/w shared access but all client address spaces had r/o shared/protected access).

Jan1979, I was con'ed into doing benchmarks on engineering 4341 (I was supporting over in bldg15, disk product test; aka one of my hobbies was enhanced production systems for internal datacenters) for national lab looking at getting 70 for compute farm ... sort of the leading edge of the coming cluster supercomputing and cluster cloud tsunami.
In the 80s, some large customers were ordering hundreds of vm/4341s at a time for putting out in departmental areas, sort of the leading edge of the coming distributed computing tsunami (inside IBM, so many departmental conferencee rooms were converted to vm/4341s, that conference rooms were becoming scarce). MVS had big issues in the explosion in vm/4341 sales ... especially the departmental machines in non-datacenter areas, 1) all the CKD disks were datacenter, only non-datacenter disks were FBA & MVS didn't have FBA support ... eventually there was a CKD "3375" emulated on FBA 3370, 2) customers were looking at the number (in some cases tens) of vm/4341s per staff, while MVS still was number of staff required per MVS system.
Also it was possible to get five vm/4341s for less cost than a 3033, higher aggregate processor and I/O throughput, and requiring much less floor space and environmentals (something like current cluster cloud, except each cloud blade can have ten times the processing of max. configured mainframe, POK was trying hard to kneecap vm/4341 systems).
note: 308x originally was going to be multiprocessor only, eventually IBM comes out with 3083 (for ACP/TPF airlines market which didn't have multiprocessor support, a 3083 was 3081 with one of the processors removed, trivia: ibm mainframes from UP to MP slowed the processor rate down by 10% to help tolerate multiprocessor cross-cache syncronization protocool ... going from two processor to single processor allowed processor rate to be speeded back up).
3081 wasn't called multiprocessor but "dyadic" ... to differentiate
from prior mainframe multiprocessors that could be split into two
single processors (for various availability reasons). In any case,
Each processor in original 3081 "D" was still claimed to have higher
throughput than 3033 ... but customer benchmarks showed 3081D
processors slower than 3033 ... so IBM introduced 3081K, with twice
the cache size to try to improve each 3081K processor to have
throughput of 3033 processor (and the two 3081K processors in
aggregate, still slower than latest Amdahl single processor).

re - comparison of 4341 with 3033
To be fair, the price of the 3081 is much less than two 3033s; and the
3033 itself has come down a lot in the last few months.
3033UP, 16meg - $2,029,000 4.8 mips
3083E, 16 meg - $1,320,000 4.0 mips
3081K, 16meg - $4,320,000 10.2 mips

From: WHEELER
to be fair, Endicott has a faster 4341mp that they won't get to
announce. POK has strapped back a 3081 to create a slowdown'ed 3083
and I expect that Endicott is now under POK's thumb, they will not be
allowed to do anything more in that area ... 4341 frame was engineered
to hold two CPUs and 16meg of 32k OEM chips (in case IBM/POK tried to
screw them on deliveries of IBM 64k chips). The E7 would only be a
little slower than the 3083. Also it is not clear from some of the
high I/O benchmark reports whether or not the 3081 technology with
high I/O rates & high task switch rates (lots of cycle stealing &
lower cache hit ratios) is faster than a 3033.
... snip ... top of post, old email index
Note in the wake of the FS failure (during FS, internal politics was
shutting down 370 efforts and lack of new 370 is cvredited with giving
clone 370 makers their market foothold), there was mad rush to get
stuff back into the 370 product pipelines, including kicking off
quick&dirty 3033&3081 in parallel; more FS, 3033, & 3081
... including 3081 (3083, 3084) worst performance/circuit of any other
mainframe product
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.]

Online sales&marketing support HONE system originally started out in the wake of the 23Jun1969 unbundling announce (charging for application software, maintenance, SE services). Part of SE training had been sort of apprentice as part of SE group onsite at customer. With unbundling, they couldn't figure out how to NOT charge for "apprentice" SE onsite. HONE started out SEs practicing with guest operating systems running in CP67 virtual machines. Science center had also ported APL\360 to CP67/CMS as CMS\APL and had redone storage management so could go from 16kbyte workspaces to large virtual memory (up to 16mbyte) demand page workspaces ... and also had done APIs for system services ... like file I/O. HONE then started offering CMS\APL-based sales&marketing support applications ... which eventually came to dominate all HONE activity (and SE practicing with guest virtual machines evaporated).
Note eventually there was requirement that all mainframe sales orders had to be processed by HONE applications ... including verifying all the various options and features, pre-reqs and co-reqs, were consistent (for various reasons started with 370/115 & 370/125).
One of my hobbies after joining IBM was enhanced production operating systems for internal datacenters and HONE was long time customer. As HONE clones propagated around the world, I was asked to go along do some of the first installs. trivia: in the mid 70s, all the US HONE datacenters were consolidated in Palo Alto. Much later when FACEBOOK first moves into silicon valley, it was into a new bldg built next door to the (former) US HONE datacenter.

had a bunch of administrative cobol applications that had to be
converted to 360 cobol (ibsys not just 7090/7094 but also 709)

IBSYS is a "heavy duty" production operating system with numerous

Univ. had a 709/1401 ... but was sold 360/67 for tss/360 (to replace 709/1401) ... as part of transition, univ got 360/30 temporarily to replace 1401... pending 360/67. Although 360/30 had 1401 emulation ... my job was to re-implement 1401 MPIO (did the tape<->unit record frontend for 709 tape->tape) on 360/30 in 360 assembler. I was given lots of manuals and got to design and implement my own monitor, device drivers, interrupt handlers, error recovery, etc ... univ. shutdown datacenter for the weekend and I had it dedicated all to myself for 48hrs (although 48hrs w/o sleep could make monday classes a little hard). Within several weeks I had 2000 card assembler program.
The 360/67 eventually shows up and replaces the 709 (& 360/30) ... but tss/360 never comes to production fruition and runs with os/360 as 360/65 ... and I'm hired fulltime responsible for OS/360. Student fortan jobs ran less than second on 709 (ibsys tape->tape) .... initially on OS/360 ran over a minute ... I install HASP (spooling) to OS/360 release 9.5 MFT and cuts time in half. OS/360 release 11 MFT ...

Downfall contributing factor that I periodically mention is IBM mainframe hardware use to be the mainstay of IBM revenue ... but that was quickly dropping with the death grip stranglehold that the communication group had on mainframe datacenters with their corporate strategic ownership of everything that crossed datacenter walls ... and fiercely fighting off client/server and distributed computing (trying to preserve their dumb terminal paradigm).
Late 80s a GPD/Adstar senior disk engineer got a talk scheduled at internal, annual, world-wide, communication group conference ... supposedly on 3174 performance, but opens the talk with statement that the communication group was going to be responsible for the demise of the disk division. They were seeing a drop in disk sales with customer data fleeing datacenters to more distributed computing friendly platforms. They had come up with number of solutions ... but they were constantly being vetoed by the communication group (with their corporate strategic ownership of everything that crossed datacenter walls). Trying to work around the corporate politics, the senior GPD/Adstar executive of software is investing in distributed computing startups that would use IBM disks ... he also asks us to visit his investments and provide any help we could.
Report around turn of century was that mainframe hardware was only a few percent of IBM revenue and dropping (all the low-handing fruit had been moved and what was left was high-valued applications where there was very high risk of changes). An analysis in EC12 time-frame that mainframe hardware was now only a couple percent of IBM revenue (and continued dropping) but that the mainframe group was 25% of IBM revenue (and 40% of profit) ... aka almost all software and services.
... note in the 70s and early 80s, I was blamed for online computer
conferencing (precursor to social media) on the IBM internal network
(non-sna and originally developed by co-worker at the science center,
larger than arpanet/internet from just about the beginning until
mid/late 80s, technology also used in the corporate sponsored
BITNET). It really took off spring of 1981 when I distributed a trip
report of visit to Jim Gray at Tandem. There were only about 300 that
participated, but claims of upwards of 25,000 were reading. Six copies
of about 300 pages of the computer conferencing were printed and along
with executive summary and summary of the summary of the summary were
packaged in Tandem 3ring binders and sent to executive committee
(folklore was 5of6 wanted to fire me). From summary of the summary:
• The perception of many technical people in IBM is that the
company is rapidly heading for disaster. Furthermore, people fear that
this movement will not be appreciated until it begins more directly to
affect revenue, at which point recovery may be impossible
• Many technical people are extremely frustrated with their
management and with the way things are going in IBM. To an increasing
extent, people are reacting to this by leaving IBM Most of the
contributors to the present discussion would prefer to stay with IBM
and see the problems rectified. However, there is increasing
skepticism that correction is possible or likely, given the apparent
lack of commitment by management to take action
• There is a widespread perception that IBM management has failed
to understand how to manage technical people and high-technology
development in an extremely competitive environment.

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 getting started, the board brings in a new CEO and reverses the breakup.

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.

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

... internal IBM politics prevent us from bidding on the RFP. the NSF
director tries to help by writing the company a letter (with support

ahead of the winning bid), as regional networks connect in, it becomes
the NSFNET backbone, precursor to modern internet

LSG to roof of bldg 12 on main plant site, bldg 12 to the San Jose T3

one of the harder HSDT problems was all internal corporate links had to be encrypted (also lots of gov. politics, especially when links cross national boundaries) ... I really hated what I had to pay for T1 link encryptors and faster encryptors were very hard to find. I got involved in doing link encryptors that could handle at least 3mbyte/sec (not mbits) and cost less than $100 to build. At first corporate crypto group claimed it couldn't be used because it seriously weakened crypto standard. Took me 3months to figure out how to explain to them what was going on ... it was hollow victory ... they then said there was only one organization in the world that could use such crypto ... I could make as many as I wanted, but they all had to be delivered to that organization. It was when I realized that there were three kinds of crypto in the world, 1) the kind they don't care about, 2) the kind you can't do, and 3) the kind you can only do for them.

First time, I tried to do it through plant site employee education ... at first they agreed, but as I provided more information including about prevailing in competitive situations, they changed their mind. They said that IBM spends a large amount of money training managers on how to handle employees ... and exposing regular employees to John Boyd wouldn't be in the best interest of IBM and I should restrict the audience to senior members of competitive analysis departments. First briefing was in bldg28 auditorium open to all (also learned that conference refreshments left for breaks, required guards, because bldg occupants would make them disappear, signs about for conference attendees *ONLY* were ignored).

when IBM was in desperate need of a make-over (at the time, the two
organizations had approx. same number of people). A couple years later
IBM has gone into the red (one of the largest corporate loses in US

John Boyd - USAF. The Fighter Pilot Who Changed the Art of Air Warfare
http://www.aviation-history.com/airmen/boyd.htm
During the 1950s, John Boyd dominated fighter aviation in the U.S. Air
Force. His fame came on the wings of the quirky and treacherous F-100;
the infamous "Hun." Boyd was known throughout the Air Force as
"Forty-Second Boyd," because he had a standing offer to all pilots
that if they could defeat them in simulated air-to-air combat in under
40 seconds, he would pay them $40. Like any gunslinger with a name and
a reputation, he was called out many times. As an instructor at the
Fighter Weapons School (FWS) at Nellis AFB, he fought students, cadre
pilots, Marine and Navy pilots, and pilots from a dozen countries, who
were attending the FWS as part of the Mutual Defense Assistance Pact.
Boyd was equally famous in the classroom where he developed the
"Aerial Attack Study." Until Boyd came along, fighter pilots thought
that air combat was an art rather than a science; that it could never
be codified. Boyd proved them wrong when he demonstrated that for
every maneuver there is a series of counter maneuvers. And there is a
counter to every counter. Afterwards, when fighter pilots attacked (or
were attacked), they knew every option open to their adversary and how
to respond. After the study was declassified, foreign pilots passing
through Nellis took it home where it changed the way every air force
in the world flies and fights. Even today, more than 40 years later,
nothing substantial has been added to the Aerial Attack Study.
... snip ...
... asked why the 40sec (since he always managed in under 20secs), he
said that there might be somebody in the world almost as good as he
was and he might need the extra time. He then invented E/M theory and
used it to redo the original F15 design (F111 followon, cutting weight
nearly in half), and used it for YF16 & YF17 (which become the F16 &
F18). By the time he passes in 1997, the USAF had pretty much disowned
him and it was the Marines at Arlington. One of his quotes:
"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."

TO ALL IBM MANAGERS:
Once again, I'm writing you a Management Briefing on the subject of
bureaucracy. Evidently the earlier ones haven't worked. So this time
I'm taking a further step: I'm going directly to the individual
employees in the company. You will be reading this poster and my
comment on it in the forthcoming issue of THINK magazine. But I wanted
each one of you to have an advance copy because rooting out
bureaucracy rests principally with the way each of us runs his own
shop.
We've got to make a dent in this problem. By the time the THINK piece
comes out, I want the correction process already to have begun. And
that job starts with you and with me.

HA/CMP after starting technical/scientific cluster scaleup work with
national labs and commercial cluster scaleup with RDBMS vendors
(Ingres, Informix, Sybase, and Oracle, they had vax/cluster support in
same source base with unix ... lots of discussions on how to
ease/improve their cluster support to HA/CMP). Old archived post about
Jan1992 Oracle meeting in Ellison's conference room on cluster scaleup
(16-way by mid-92, 128-way by ye-92).

Within a few weeks of the Ellison meeting, cluster scaleup was transferred, announced as IBM supercomputer (for technical/scientific *ONLY*) and we were told we couldn't work on anything with more than four processors (mainframe DB2 was also complaining that if we allowed to go ahead with commercial cluster scaleup, it would be at least 5yrs ahead of them). We leave IBM a few months later.
Later was brought in as a consultant to small client/server startup. Two of the former Oracle people (from the HA/CMP Ellison meeting and involved with cluster scaleup) were there, responsible for something called a "commerce server" and they wanted to do payment transactions on the server.

supercomputing centers with 24 RT-PCs in parallel implemented by IBM as
"parallel routers". The T1 idea is so successful that proposals for T3

Early 80s, I had HSDT project doing T1 and faster computer links (both
terrestrial and satellite) and was working with the NSF director and was
supposed to get $20M to interconnect the NSF supercomputer centers; then
congress cuts the budget, some other things happen and eventually
releases an RFP (in part based on what we already had running, like
requring T1 links). Preliminary announce (Mar1986)

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.

Internal politics prevent us from bidding ... the NSF director tries to help by writing the company a letter (with support from other agencies) but that just makes the internal politics worse (as well as comments that what we already had running was at least 5yrs ahead of winning bid). Note the winning bid had (PC/RT) 440kbit links and to give it appearance of meeting the RFP, had T1 trunks with telco multiplexors running multiple 440kbit links over the T1 trunks. I would ridicule why didn't they call it a T5 network ... since possible some of the T1 trunks were possibly multiplexed in turn over T5 trunks someplace.
They did ask me to be the "red team" for the T3 response .... the "blue team" had couple dozen people from half dozen labs around the world. I presented 1st then the blue team presented. Five mins into the blue team presentation, the executive in charge, pounded on the table saying he would lay down in front of a garbage truck before he let any but the blue team proposal go forward.

Decline of America, 1970 to the Present
https://www.amazon.com/Age-Greed-Triumph-Finance-Decline-ebook/dp/B004DEPF6I/
pg187/loc3667-70:
When Welch took over GE in 1980, it was the ninth most profitable
company in the nation. Now it was first, second, or third. Shareholder
value reached $500 billion, more than any other company in
America. The stock price was Welch's personal measure of achievement,
though he later denied it. The boom of the late 1990s on balance sent
the wrong message to American managers: cut costs rather than
innovate. Despite its appeal, In Search of Excellence had little true
staying power.
... GE Capital & its securitized mortgages took down the company; then
failing to fund workers pension plan pg191/loc3754-60:
In 1977, GE Capital, as it was later called, generated $67 million in
revenue with only seven thousand employees, while appliances that year
generated $100 million and required 47,000 workers. He hired better
managers and supplied GE Credit with a lot of capital, and he had
built-in scale--meaning large size--due to GE's assets size and
triple-A credit rating. In time, GE Capital became a full-fledged
bank, financing all kinds of commercial loans, issuing mortgages and
other consumer loans, and becoming a leader in mortgage-backed
securities. By the time Welch left in 2000, GE Capital's earnings had
grown by some eighty times to well more than $5 billion, while the
number of its employees did not even double. It provided half of GE's
profits.
pg192/loc3777-79:
In a few brief sentences, Welch had defined a new age for big
business. He introduced short-run profit management to GE,
understanding that stock market investors trusted little so well as
rising profits every calendar quarter. It became the best indication
of a company's quality, making it stand out in good times and bad.
pg199/loc3909-13:
GE Capital also enabled GE to manage its quarterly earnings, engaging
in the last couple of weeks of every calendar quarter in various
trades that could push earnings up on the last day or two before the
quarter's end. It was an open secret on Wall Street that this was how
Welch consistently kept quarterly earnings rising for years at a
time. "Though earnings management is a no-no among good governance
types," wrote two CNNMoney financial editors, "the company has never
denied doing it, and GE Capital is the perfect mechanism."
pg199/loc3919-25:
Over his tenure, he cut back significantly on research and
development--by some 20 percent in the 1990s. In 1993, he told
BusinessWeek, "We feel that we can grow within a business, but we are
not interested in incubating new businesses." GE Capital itself was
built through countless acquisitions. As the CNNMoney writers put it,
"Consider first what the company really is. Its strength and curse is
that it looks a lot like the economy. Over the decades GE's well-known
manufacturing businesses--jet engines, locomotives, appliances, light
bulbs--have shrunk as a proportion of the total. Like America, GE has
long been mainly in the business of services. The most important and
profitable services it offers are financial."
pg200/loc3935-41:
He mostly stopped trying to create great new products, hence the
reduction in R&D. He took the heart out of his businesses, he did not
put it in, as he had always hoped to do. What made his strategy
possible, and fully shaped it, was the rising stock market--and the
new ideology that praised free markets even as they failed.

https://www.theatlantic.com/ideas/archive/2020/02/how-mckinsey-destroyed-middle-class/605878/
A new ideal of shareholder primacy, powerfully championed by Friedman
in a 1970 New York Times Magazine article entitled "The Social
Responsibility of Business is to Increase its Profits," gave the newly
ambitious management consultants a guiding purpose. According to this
ideal, in language eventually adopted by the Business Roundtable, "the
paramount duty of management and of boards of directors is to the
corporation's stockholders." During the 1970s, and accelerating into
the '80s and '90s, the upgraded management consultants pursued this
duty by expressly and relentlessly taking aim at the middle managers
who had dominated mid-century firms, and whose wages weighed down the
bottom line.

inequality--inequality among wage earners and the rising share of
overall income going to owners of capital rather than to workers for
their labor. However, since researchers and analysts may still be

From: Lynn Wheeler <lynn@garlic.com> Subject: Destruction Of The Middle Class Date: 05 June 2022 Blog: Facebookre:
In the 70s, congress had put import quotas on (inexpensive) foreign cars, supposedly to cut competition to give US industry enormous profits that would be used to completely remake themselves, but they just pocketed the money and continued business as usual. In the early 80s, there was articles about imposing a 100% unearned profit tax on the US auto industry.
Note restricting inexpensive foreign makers allowed the US industry to nearly double prices over a couple years. From law of unintended consequences, downside was salaries didn't keep pace, so 36month auto loans had to increase to 60-72months ... however banks wouldn't make the longer loans w/o warranty being for the life of the loan. The longer warranties were starting to eat into their enormous (unearned) profits.
1990, there was the "C4 taskforce" in the auto industry to look at significantly remaking themselves (finally). C4 taskforce was planning on heavily leveraging IT technology as part of the remake and invited major IT vendors to send representatives to participate; I was selected as one of the reps from IBM. The taskforce could accurately describe what the foreign makers were doing (well) and how US needed to change to compete. Autos were taking 7-8yrs from conception to rolling off the line (with cosmetic changes in between), with two efforts going on concurrently, offset 3-4yrs (to make it look like it wasn't taking as long).
Note: with the import quotas, foreign competition realized that they could sell that many high-end cars (as low-end) ... so they changed their products ... as part of changing the product, they cut the elapsed time to bring out new auto in half (3-4yrs) and in 1990, they were in process of cutting it in half again (18-24months) ... which met they could adapt to changing technology and/or customer preferences much faster (agile).
The US auto industry had also spun off their parts subsidiaries during the 80s and were now finding some parts in the original designs were no longer available 7-8yrs later. They then had costs&delays to go back and redo design. Their example was the Corvette which had particularly tight space tolerances (under the skin/shell).
Only slightly related: 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.

Jan1979 got con'ed into doing IBM vm/4341 benchmark for national lab that was looking at getting 70 for compute farm ... sort of the leading edge of the coming cluster supercomputer tsunami ... also cloud megadatacenters ... there was big tech overlap between commodity supercomputer clusters and commodity cloud clusters.
Then in the 80s, large companies had orders for hundreds of vm/4341s to place out in departmental areas ... sort of the leading edge of the coming distributed computing tsunami (see upthread reference to IBM disk division claimed that IBM communication group was going to be responsible for the demise of the disk division, communication group had stranglehold on mainframe datacenters and fiercely fighting off client/server and distributed computing)
Then starting decade later, the last product did at IBM was HA/CMP,
started out HA/6000 for the NYTimes to port their newspaper system
(ATEX) to RS/6000. I renamed it HA/CMP after starting
technical/scientific cluster scaleup work with national labs and
commercial cluster scaleup with RDBMS vendors (Ingres, Informix,
Sybase, and Oracle, they had vax/cluster support in same source base
with unix ... lots of discussions on how to ease/improve their cluster
support to HA/CMP). Old archived post about Jan1992 Oracle meeting in
Ellison's (Oracle CEO) conference room on cluster scaleup (16-way by
mid-92, 128-way by ye-92).
http://www.garlic.com/~lynn/95.html#13
Within a few weeks of the Ellison meeting, cluster scaleup was transferred, announced as IBM supercomputer (for technical/scientific *ONLY*) and we were told we couldn't work on anything with more than four processors (mainframe DB2 was also complaining that if we allowed to go ahead with commercial cluster scaleup, it would be at least 5yrs ahead of them). We leave IBM a few months later.

Watson on original sql/relational implementation ... System/R ... then
managed to do tech transfer to Endicott for SQL/DS, "under the radar"

The univ. had been running 709/1401, 709 IBSYS tape->tape and 1401 unit record front end for 709 (tapes manually move between 709 and 1401 7track drives). The univ had been sold 360/67 for tss/360 replacing the 709/1401 ... and IBM supplied 360/30 replacing 1401 pending availability of 360/67. The univ. shutdown datacenter on weekends and I had the whole place all to myself for 48hrs straight, although 48hrs w/o sleep made monday classes a little difficult. I was given whole bunch of manuals and turned loose. I got to design/implement my own monitor, interrupt handlers, device drivers, error recovery, storage management, etc. Within a few weeks I had a 2000 card assembler program (note: 360/30 had 1401 emulation, but I guess I was guinea pig learning 360).
My assembler program had conditional assembly that produced OS/360 version with get/put and DCB macros or a stand-alone version (loaded with the BPS card loader). The stand-alone version took 30mins to assemble, but the OS/360 version took a little over an hour ... each DCB macro 5-6mins elapsed (OS/360 PCP release 6). I quickly learned to read punch card holes for assembler output "12-2-9 TXT" deck (256 hex) and do card patches (simple fixes faster than re-assembling) ... fan the card deck looking for the TXT card with the hex displacement into the program (for the card to patch, dup card in 029 keypunch out to patch and then multi-punch).
trivia: card->tape and tape->punch needed to handle (709) BCD cards and "binary cards" (binary cards had two 6bit "bytes" punched in each 12 hole column). 2540 reader/punch had support for "column binary mode" ("binary" cards taking 160 360 bytes).

Corporations used to be for organizations that did things in the public interest. Almost from the start there has been efforts to allow corporations to operate in self-interest and then to give corporations "rights" (as people).
False Profits: Reviving the Corporation's Public Purpose
https://www.uclalawreview.org/false-profits-reviving-the-corporations-public-purpose/
I Origins of the Corporation. Although the corporate structure dates
back as far as the Greek and Roman Empires, characteristics of the
modern corporation began to appear in England in the mid-thirteenth
century.[4] "Merchant guilds" were loose organizations of merchants
"governed through a council somewhat akin to a board of directors,"
and organized to "achieve a common purpose"[5] that was public in
nature. Indeed, merchant guilds registered with the state and were
approved only if they were "serving national purposes."[6]

In the 1880s, Supreme Court were scammed (by the railroads) to give
corporations "person rights" under the 14th amendment.
https://www.amazon.com/We-Corporations-American-Businesses-Rights-ebook/dp/B01M64LRDJ/
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.
... testimony falsely claiming authors of 14th amendment intended to
include corporations, 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

"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."

Management Briefing
Number 1-72: January 18,1972
ZZ04-1312
TO ALL IBM MANAGERS:
Once again, I'm writing you a Management Briefing on the subject of
bureaucracy. Evidently the earlier ones haven't worked. So this time
I'm taking a further step: I'm going directly to the individual
employees in the company. You will be reading this poster and my
comment on it in the forthcoming issue of THINK magazine. But I wanted
each one of you to have an advance copy because rooting out
bureaucracy rests principally with the way each of us runs his own
shop.
We've got to make a dent in this problem. By the time the THINK piece
comes out, I want the correction process already to have begun. And
that job starts with you and with me.

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.

another Welch article:

'Trumpism'. A new book explains why he was wrong
https://www.businessinsider.com/how-neutron-jack-fired-thousands-made-trump-broke-capitalism-2022-5
Welch was obsessed with growth and spent about $130 billion on nearly
1,000 acquisitions during his time running GE, although many of them
failed. Under Welch the company's financial services division, GE
Capital, became enormous but it later needed a $139 billion bailout
from the US government following the 2008 financial crisis, as well as
a $3 billion rescue investment by Warren Buffett, Gelles says.
...
'Jack Welch rigged the game' for Trumpism
More damaging, though, was the thinking Welch inspired among other
business leaders. Gelles says his approach was embraced by Jim
McNerney, who as Boeing CEO was accused of embarking on a range of
cost-cutting measures that contributed to the Boeing 737 Max disasters
that killed 346 people five months apart.

disclaimer: after leaving IBM was brought in as consultant to small client/server company that wanted to do payment transactions on their server, they had also invented this technology called "SSL" they wanted to use, result is now frequently called "electronic commerce". As part of doing "electronic commerce", got roped into financial standards (X9) and other industry activity. Then in Jan1999 was asked to try and help stop the coming economic mess (we failed). A decade later (Jan2009) was asked to HTML'ize the Pecora Hearings (senate looking at the '29 crash, resulted in jail time and Glass-Steagall) with lots of internal hrefs and URLs comparing what happen then and what this time (comment that the new congress might have an appetite to do something). I work on it for awhile and then get a call that it won't be needed after all (comment that capital hill was completely buried under enormous mountains of wallstreet cash).

disclaimer 2: I took two credit hr intro to fortran/computers and then within a year of taking the intro class, univ. hires me fulltime to be responsible for os/360 ... 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 help monetize the investment, including offering services to non-Boeing entities). I think Renton was possibly largest datacenter in the world, 360/65s arriving faster than they could be installed, boxes constantly staged in the hallways around the machine room. Lots of politics between Renton manager and CFO, who only had a 360/30 up at Boeing field for payroll (although they enlarged the room for 360/67 for me to play with when I wasn't doing other stuff). When I graduate, I leave Boeing and join the IBM Cambridge Science Center. Much later there is lots of strife with the Boeing take-over of McDonnell-Douglas
Boeing 100th anniv article "The Boeing Century"
https://issuu.com/pnwmarketplace/docs/i20160708144953115
included long article Scrappy start forged a company built to last, has analysis of the Boeing merger with M/D ("A different Boeing") and the disastrous effects that it had on the company ... and even though many of those people are gone, it still leaves the future of the company in doubt. One was the M/D (military-industrial complex) culture of outsourcing to lots of entities in different jurisdiction as part of catering to political interests ... as opposed to focusing on producing quality products ... which shows up in the effects that it had on 787 (and later 737 MAX).
The Coming Boeing Bailout?
https://mattstoller.substack.com/p/the-coming-boeing-bailout
Unlike Boeing, McDonnell Douglas was run by financiers rather than
engineers. And though Boeing was the buyer, McDonnell Douglas
executives some how took power in what analysts started calling a
"reverse takeover." The joke in Seattle was, "McDonnell Douglas bought
Boeing with Boeing's money."

Crash Course
https://newrepublic.com/article/154944/boeing-737-max-investigation-indonesia-lion-air-ethiopian-airlines-managerial-revolution
Sorscher had spent the early aughts campaigning to preserve the
company's estimable engineering legacy. He had mountains of evidence
to support his position, mostly acquired via Boeing's 1997 acquisition
of McDonnell Douglas, a dysfunctional firm with a dilapidated aircraft
plant in Long Beach and a CEO who liked to use what he called the
Hollywood model" for dealing with engineers: Hire them for a few
months when project deadlines are nigh, fire them when you need to
make numbers. In 2000, Boeing's engineers staged a 40-day strike over
the McDonnell deal's fallout; while they won major material
concessions from management, they lost the culture war. They also
inherited a notoriously dysfunctional product line from the
corner-cutting market gurus at McDonnell.

Boeing's travails show what's wrong with modern capitalism.
Deregulation means a company once run by engineers is now in the

From: Lynn Wheeler <lynn@garlic.com> Subject: Operating System File/Dataset I/O Date: 07 June 2022 Blog: FacebookVS2 prototype started out doing "SVS" ... little different than running MVT in a 16mbyte (CP/67) virtual machine ... but the code to build a 16mbyte virtual memory table was moved inside MVT. The biggest issue was channel programs required real addresses and all the application/library built channel program passed in EXCP/SVC0 call had virtual addresses ... basically (CP67) CCWTRANS was wired into EXCP to build a copy of the channel program ... but with real addresses.
Move to MVS gave each application a 16mbyte virtual address space ... however because of the extensive use of pointer-passing APIs in OS/360 ... an 8mbyte image had to be mapped into every 16mbyte virtual address space (so the kernel code could just directly access the parameter list as if it was OS/360 running in real memory). Problem was that MVT subsystems were moved into their own 16mbyte virtual address space ... and for applications calling subsystems, they created the "common segment area" (or CSA), a 1mbyte segment mapped into every application 16mbyte virtual address space (application space now reduced to 7mbytes) where API could stash parameters when calling a subsystem. Then because API space for calling subsystems was somewhat proportional to number of concurrently executing applications and number of subsystems, common segment requirement quickly became "Common System Area also CSA" as it balloons to 5or6mbytes (leaving only 2 or 3mbytes for applications) and was threatening to explode to 8mbytes (leaving zero for applications).
other trivia; a decade ago, I got asked to track down the decision to
make all 370s "virtual memory". I eventually found somebody that was
staff to the executive. Basically, MVT storage management was so bad
that execution regions had to be four times larger than normally used
... a typical 1mbyte 370/165 could only have four regions ... not
sufficient to keep processor busy and justified. Going to virtual
memory would allow number of regions to be increased by a factor of
four times ... with little or no paging. Reference to tracking
down decision to make all 370s virtual memory

some rivalry between cp67/cms on the 4th flr and multics on 5th flr
http://www.multicians.org/thvv/360-67.html
OS/360 executables were "relocatable" in the sense that executable image contained address constants, the whole program had to be brought into memory and the addresses modified to reflect the loaded location.
CP67/CMS had adopted many of its language applications from OS/360 ... so relied on OS/360 conventions. I had devil of a time when I did paged mapped filesystem for CP67/CMS and making applications generated from OS/360 language applications using the "relocatable" address constants ... since it modified the executable image ... and I wanted to have the same (read/only, unchanged) executable image shareable concurrently in multiple address spaces at potentially different locations.
In the early 70s, future system project had adopted the TSS/360
"single-level-store" paradigm but was completely different from 370
... and was going to completely replace 370. After FS implodes,
"single-level-store" got a bad reputation ... lot more FS info
http://www.jfsowa.com/computer/memo125.htm
Even tho I claimed I had learned from tss/360 what not to do for my cp67/cms paged-mapped filesystem ... and upgraded to vm370/cms ... it was impossible to get it approved for release with the adverse bad reputation from FS, just had it running at lots of internal IBM datacenters).

virtualization experience starting Jan1968, online at home since Mar1970
From: Lynn Wheeler <lynn@garlic.com> Subject: Operating System File/Dataset I/O Date: 07 June 2022 Blog: Facebookre:
I had taken two credit hr intro to fortran/computers and at the end of the semester got student programming job to re-implement 1401 MPIO on 360/30. Univ. had been sold 360/67 for tss/360 to replace 709 (ibsys tape->tape) and 1401 (unit record front end for 709, tape<->reader/printer/punch). 360/30 replaced 1401 pending arrival of 360/67 (360/30 had 1401 emulation mode, I guess I was hired just as part of of univ. getting 360 experience). I was given a bunch of manuals and got to design/implement my own monitor, device drivers, interrupt handlers, error retry/handiing, storage management, etc. The univ. shutdown the datacenter over the weekend and I had the whole place dedicated to myself, although 48hrs w/o sleep could make monday classes a little hard ... within a few weeks I had 2000 card assembler program. Read card by card ... 709 tape files had two formats, 80byte record bcd card image and 160byte record binary card image (two 6bit bytes punched two "bytes" per 12 hole column) ... read card input, 1st read 80 char BCD, if error, tried reread in 160 byte column binary.
360/67 finally came in, but tss/360 never came to production fruition and so ran as 360/65 with os/360 and I was hired fulltime responsible for os/360 ... used for lots of administration cobol applications and student fortran jobs. Student fortran jobs had ran under second on 709 ... started out over a minutes on OS/360 on (360/67 as) 360/65. I install HASP and it cut time in half. I then start doing highly customized SYGGENs for careful placement of datasets and PDS members, for optimized arm seek and PDS directory member multi-track search ... which cut another 2/3rds to 12.9secs. Never got better than 709 until installed Univ. of Waterloo WATFOR.
Some people came out from the science center and installed CP67/CMS at the univ (3rd installation after science center and MIT lincoln labs) and I got to play with it a lot in my weekend window ... but never had support for all the administration cobol workload (most ported over from 709 cobol). IBM TSS/360 SE was still hanging around and sometime came in on weekends and I had to share my weekend window (joke was at its peak TSS/360 had 1200 people while the CP67/CMS group at science center had 12 people). We did a synthetic fortran edit, compile, and execute benchmark for both TSS/360 and CP67/CMS. CP67/CMS running 35 simulated users had much better throughput and interactive response than TSS/360 running 4 simulated users. I then started rewriting lots of CP67/CMS code trying to improve throughput of OS/360 in virtual machine. Benchmark was batch program ran 323secs on bare machine and start at 856secs under CP67 (533 secs CP67 cpu overhead). Within six months I had down to 113 CP67 cpu overhead.
Upthread I mention Van Vleck story about CP67 crashing 27 times in one
day. CP67 delivered to univ. had 1052 & 2741 terminal support with
automagic terminal type identification. Univ had some ASCI TTY33
terminals and so I added ascii/tty support ... but had some fiddling
with one byte (255char) line lengths. IBM got in habit of picking up a
lot of my changes and including in shipped CP67. Tom was supporting
MIT USL CP67/CMS located in bldg across the quad from the bldg
multics/IBM in (behind Land's 2story bldg in tech sq off main st). He
had somebody down at harvard that wanted to use some sort of ascii
device (plotter?) and tried increasing max. length to 1200chars
... but hadn't changed my fiddle with one byte length calculation
... which resulted in buffer overruns and crashing the system
http://www.multicians.org/thvv/360-67.html
Before i graduate, I'm hired 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-IBM entities). Just Renton datacenter I thought possibly largest in the world, couple hundred million in IBM 360s (1960s dollars) ... 360/65s were arriving faster than they could be installed, boxes constantly staged in the hallways around the machine room. Lots of politics between renton manager and CFO ... who just had a 360/30 for payroll up at Boeing field (although they enlarged it and install 360/67 for me to play with when I wasn't doing other stuff). When I graduate, I join the science center, instead of staying at Boeing.
One of my hobbies after joining IBM was enhanced production operating
systems for internal datacenters (and continued to work on 360/370
stuff all during FS, even periodically ridiculing them drawing analogy
with FS and a long running cult film running down at central sq
... which wasn't exactly career enhancing) ... including the online
sales&marketing support "HONE" systems ... numbers really exploded
after they started doing HONE clones all over the world. I would joke
it wasn't fair to compare number of customer IBM online systems with
number of Multics systems, or even number of internal IBM systems with
number of Multics systems, but at peak, I had more of my enhanced
systems (over hundred) than the total number of Multics systems that
ever existed.

CFTC used to require that commodity players had significant position because speculators were causing wild irrational price fluctuation (i.e. they profited by manipulating price, buy low sell high, then short sale on the way day ... including manipulating news to push price in the direction they wanted. But then CFTC sent (secret) letters to selected speculators allowing them play ... responsible for the huge oil&gas price hike summer of 2008.
Later a member of congress published the transactions for 2008 showing the speculators that were responsible for the huge price spike summer of 2008. Instead of vilifying the speculators responsible, somehow the press vilified the member of congress for violating corporation privacy (as if corporations were people, disinformation to distract from those responsible). Guess who at the top of the list???

If it IPL's then JES won't start,

$4K - MVS was the first operating system for which the IBM Salesman
got a $4000 bonus if he/she could convince their customer to install
VS 2.2 circa 1975. IBM was really pissed off that this fact became
known thru this
... snip ...
... a decade ago, I was asked if I could track down decision to make
all 370s "virtual memory" ... found somebody on the executive's staff
... basically MVT storage management was so bad that regions had to be
four times larger than used and typical 1mbyte 370/165 would only have
four regions ... insufficient throughput and utilization to justify
165. going to virtual memory would allow number of regions to be
increased by a factor of four times with little or no paging. post

trivia: in the 2nd half of the 70s, when I transferred from science center out to san jose research, i got to wander around IBM (and non-IBM) datacenters in silicon valley ... including disk engineering (bldg14) and disk product test (bldg15) across the street. Disk engineering had around the clock, pre-scheduled, stand-alone mainframe testing. They said that MVS had been tried, but in that environment, had 15min mean-time-between-failure (requiring manual re-ipl). I offered to rewrite input/output supervisor making it bullet proof and never fail ... allowing any amount of concurrent, on-demand testing (greatly improving productivity).
Downside was engineers kneejerk was to blame me for any of their problems and I had to spend increasing amount of time playing disk engineer diagnosing their problems. I then wrote up work for research report and happened to mention the MVS 15min MTBF ... bringing down the wrath of the MVS organization on my head (claims were they tried to have me separated from the company, when that didn't work they tried to make things as unpleasant as possible).
Later, just before 3380 drives were about to ship ... FE had hardware regression test of 57 simulated 3380 errors likely to occur, in all 57 cases, MVS would fail (requiring re-ipl) and in 2/3rds of the cases there was no indication of what caused the failure (I didn't feel badly at all).

On the 360 announcement day, Boeing gives the rep an order (who barely knows what a 360 is) ... on commission, he is highest paid IBM employee that year. The next year, IBM changes from commissions to quota ... by end of January the rep has made 100% quota for the year (on another Boeing order) and his quota is "adjusted" ... he leaves IBM.

... supercomputer topic drift ... Jan1979 I had been con'ed into doing vm/4341 benchmarks for a national lab looking at getting 70 for a compute farm (sort of leading edge of the coming cluster scaleup supercomputer tsunami). About the same time I was doing some work with Jim Gray and Vera Watson on the original sql/relational implementation ... System/R.
The last product we did at IBM was HA/CMP. It started out HA/6000 for the NYTimes to move their newspaper system (ATEX) off (DEC) Vaxcluster to RS/6000. However as I started doing technical/scaleup cluster scaleup with national labs and commercial cluster scaleup with RDBMS vendors (Ingres, Informix, Sybase, Oracle, all had vax/cluster support in the same source base with unix support ... lots of discussion on improving over vaxcluster and easing RDBMS port to HA/CMP). However, nearly every time we visited national labs (including LANL & LLNL) we would get hate mail from the Kingston supercomputer group (working on more traditional supercomputer design).
Oct1991 senior VP backing the Kingston group, retires and there are audits of his projects. Shortly later there is announcement of internal supercomputing conference (effectively trolling the company for technology). Early Jan1992 we have meeting in Ellison's (Oracle CEO) conference room on (commercial) cluster/scaleup, 16way by mid92, 128way by ye92. Then within a few weeks of the Ellison meeting, cluster scaleup is transferred, announced 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. Possibly contributing was mainframe DB2 group complaining that if we were allowed to continue, it would be years ahead of them.

Late 80s, senior disk engineer gets a talk scheduled annual, internal, world-wide, communication group conference, supposedly on 3174 performance ... but opens the talk with the statement that the communication group was going to be responsible for the demise of the disk division. The communication group had strangle hold on mainframe datacenters with their corporate strategic responsibility for everything that crossed datacenter wall and were fiercely fighting off client/server and distributed computing (trying to preserve their dumb terminal paradigm). The disk division was seeing data fleeing mainframe datacenters to more distributed computing friendly platforms, with drops in disk sales. They had come up with a number of solutions ... which were constantly being vetoed by the communication group.

Many years earlier, both the Boeing and IBM marketing people tell tale about prior IBM marketing rep. On the 360 announcement day, Boeing gives the rep an order (who barely knows what a 360 is) ... on commission, he is highest paid IBM employee that year. The next year, IBM changes from commissions to quota ... by end of January the rep has made 100% quota for the year (on another Boeing order) and his quota is "adjusted" ... he leaves IBM.
I take 2 credit hr intro to fortran/computers, at the end of the semester get student programming job, then within a year am hired fulltime responsible for os/360 (univ had 709/1401 but was sold 360/67 for tss/360 replacing 709/1401 ... tss/360 never came to production fruition, so ran as 360/65 with os/360).
Then before I graduate, I'm hired 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). I think just renton datacenter is possibly largest in the world (couple hundred million in 360s, 1/10th spook base??) ... 360/65s arriving faster than they could be installed, boxes constantly staged in hallways around machine room. Lots of politics between renton manager and CFO who only had 360/30 up at boeing field for payroll ... although they enlarge it for a 360/67 for me to play with when I'm not doing other stuff. When I graduate, I join IBM science center (instead of staying at Boeing).
turns out I was at Boeing about the same time he was at "spook base". another account of Boyd
John Boyd - USAF. The Fighter Pilot Who Changed the Art of Air Warfare
http://www.aviation-history.com/airmen/boyd.htm
During the 1950s, John Boyd dominated fighter aviation in the U.S. Air
Force. His fame came on the wings of the quirky and treacherous F-100;
the infamous "Hun." Boyd was known throughout the Air Force as
"Forty-Second Boyd," because he had a standing offer to all pilots
that if they could defeat them in simulated air-to-air combat in under
40 seconds, he would pay them $40. Like any gunslinger with a name and
a reputation, he was called out many times. As an instructor at the
Fighter Weapons School (FWS) at Nellis AFB, he fought students, cadre
pilots, Marine and Navy pilots, and pilots from a dozen countries, who
were attending the FWS as part of the Mutual Defense Assistance Pact.
Boyd was equally famous in the classroom where he developed the
"Aerial Attack Study." Until Boyd came along, fighter pilots thought
that air combat was an art rather than a science; that it could never
be codified. Boyd proved them wrong when he demonstrated that for
every maneuver there is a series of counter maneuvers. And there is a
counter to every counter. Afterwards, when fighter pilots attacked (or
were attacked), they knew every option open to their adversary and how
to respond. After the study was declassified, foreign pilots passing
through Nellis took it home where it changed the way every air force
in the world flies and fights. Even today, more than 40 years later,
nothing substantial has been added to the Aerial Attack Study.
... snip ...
... asked why "40 secs" when he always did it in 20 secs ... he said that there might be somebody in the world almost as good as he was and he might need the extra time

From: Lynn Wheeler <lynn@garlic.com> Subject: System Dumps & 7x24 operation Date: 11 June 2022 Blog: FacebookIn the 60s, the science center and two commercial online service bureaus (spinoffs from the science center) did a lot of CP67 work for 7x24 availability operation (including darkroom and no human present). At the time, IBM leased/rented machines with charges (even "funny money" for IBM internal datacenters) based on the processor "system meter" ... that ran whenever any processor and/or channel was busy. Special channel programs were done for online terminals ... which would go idle, but instant on for arriving characters (allowing system meter to stop when system was idle, trivia: all processors and channels had to be idle for at least 400ms before the system meter would stop, long after IBM had converted to sales, MVS still had a timer task that woke up every 400ms, guaranteeing system meter would never stop).
Other 60s 7x24 work was system dump automatically written to disk file
(instead of printer) and system would automagically re-ipl (with no
human intervention). Old account of MIT USL programmer modified CP67
which resulted in 27 crashes (automagic dump and re-ipl) in single
day.
http://www.multicians.org/thvv/360-67.html
An application was developed for processing dump file (1st cp67 and later vm370) ... although function was little different from dealing with real paper dump. With appearance of REX (before renamed REXX and release for customers), I wanted to demo that it wasn't just another pretty scripting language ... and chose to reimplement the (at the time vm370) dump application in REX with ten times the performance (compared to the assembler implementation, some slight of hand for interpreted REX) and ten times the function ... doing it in half time over three months. I finished early, so started implementation of automagic library that looked for most common failure signatures.
I thought it would be released to customers in place of the current application, but for various reason it wasn't even tho it was in use by nearly every PSR and internal datacenter. Eventually I got permission to give presentations at user group meetings on the implementation ... and within a few months, non-IBM implementations started to appear.
Trivia: old email from the 3090 service processor group (3092) about
including it as part of 3092 service processor
http://www.garlic.com/~lynn/2010e.html#email861031
http://www.garlic.com/~lynn/2010e.html#email861223
other triva: after CP67 was made available to the univ (3rd installation after science center itself and MIT Lincoln Labs) ... I wrote &/or rewrote a lot of CP67(& CMS) code that IBM would pickup and ship in product to customers. CP67 had 2741 and 1052 support, and the univ. had some ASCII TTY33 terminals ... so I added ASCII TTY33 support (which IBM shipped). For TTY33, I fiddled some length calculations using one byte (255char) values. Some MIT USL user down at Harvard got some sort of ASCII device (I think a "plotter") that needed 1200char max line length (not 255) ... the simple change for 1200 char resulted in invalid length calculations, crashing the system.

bureaucracy & syncophancy from future system failure in the 70s (quote mentioned upthread) ...
I was introduced to John Boyd in the early 80s, and use to sponsor his briefings at IBM. The first time, I tried to do it through plant site employee education. At first they agreed, but as I provided more information about how to prevail/win in competitive situations, they changed their mind. They said that IBM spends a great deal of money training managers on how to handle employees and it wouldn't be in IBM's best interest to expose general employees to Boyd, I should limit audience to senior members of competitive analysis departments. First briefing in bldg28 auditorium open to all.
... sort of the opposite ... and similar to many things in Boyd's
briefings .. from HBS article 2005 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.

From: Lynn Wheeler <lynn@garlic.com> Subject: Window Display Ground Floor Datacenters Date: 12 June 2022 Blog: FacebookI had taken two credit hr intro fortran/computers, at end of semester got student job reimplementing 1401 MPIO for 360/30 (univ. had 709/1401 with 1401 unit record front-end for 709 tape->tape and had been sold 360/67 for tss/360 ... and temporary got 360/30 pending availability of 360/67, even tho 360//30 had 1401 emulation mode ... I guess my job was just part of getting 360 experience). Within year of intro class, I was hired fulltime responsible for OS/360 (360/67 ran as 360/65, tss/360 never came to production quality).
student fortran jobs ran less than second on 709, but started out over a minute on os/360. I install hasp and cut time in half. First sysgen I did was mft release 11 ... I took apart the SYSGEN2 deck putting it back together for careful placement of datasets and PDS members (arm seek and PDS directory multi-track search optimization) ... cutting another 2/3rds to 12.9secs for student fortran. Never beat 709 until install Univ. of Waterloo WATFOR.
For MVT release 15/16, got 3rd shift time at the IBM regional office in Seattle. Datacenter was on ground floor with large glass windows.
During the day, wander around the bldg and found MVT debugging class and asked if I could attend. I lasted less than 20mins ... the instructor asked me to leave because I kept suggesting things.
Then before I graduate, I'm hired fulltime into a small group in the Boeing CFO office to help with the formation of Boeing Computing Services (consolidate all dataprocessing into 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 (a couple hundred million in computer systems), 360/65s were arriving faster than they could be installed, boxes constantly staged in the hallways around the machine room. Lots of politics between renton manager and the CFO who only had a 360/30 up at boeing field for payroll (although they enlarged the room for a 360/67 for me to play with when I wasn't doing other stuff).

... note above appears to lump Social Security Trust Fund in with the
rest of the gov collections and "spending". The SS Trust Fund was set
up for people to pay in as a pension plan ... that they would draw on
when they retired. However, with fast growing working population (in
large part the baby boomer/bubble), there have been significant
principle accumulating (more payed in each year than amount payed out)
and the government was "borrowing" the excess for other purposes
(leaving IOUs). With the baby boomers retiring that is starting to
invert and the gov. will have to start paying off those IOUs. Reagan's
"budget director" takes credit for analysis that increased SS
contributions to cover increases in life expectancy and the coming
baby boomer retirement. However, he also states that it was somewhat
of a cover story, wanting to have more SS Trust Fund money to borrow
for military-industrial complex spending ... without having to
increase standard taxe rates (also to double tax SS, contributions
come out of after taxed income, and then benefits taxed
again). However, other places Greenspan claimed credit. Some recent
political rhetoric appear to obfuscate the nature of the trust fund
and the debt it is owed ... as if they are planning on
defaulting/welshing on the debt
https://en.wikipedia.org/wiki/Social_Security_Trust_Fund
2002 congress lets the financial responsibility act lapse (spending can't exceed revenue, on its way to eliminating all federal debt).
https://www.cbpp.org/research/federal-budget/the-pay-as-you-go-budget-rule
In the late 1990s, however, Congress and the President began waiving
PAYGO in response to the booming economy and several years of budget
surpluses. In 2001 they waived PAYGO enforcement and approved very
large tax cuts without offsets -- a sharp departure from PAYGO
discipline. This set the stage for other PAYGO exceptions. In 2002
Congress allowed PAYGO to expire, facilitating the passage of
deficit-increasing tax and entitlement legislation over the next
several years, including the 2003 tax cuts and the Medicare
prescription drug bill.
... snip ...
... by 2005, comptroller general was including in speeches that nobody in congress was capable of middle school arithmetic (for how badly they were savaging the budget). 2010 CBO report 2003-2009 tax revenue cut by $6T and spending increased by $6T for $12T gap compared to fiscal responsible budget (first time taxes were cut to not pay for two wars). Sort of confluence of FEDRES and TBTF (too big to fail) needed huge federal debt, special interests wanting huge tax cut and military-industrial complex wanting huge spending increase.
CBS 60mins had expose on medicare part-d legislation ... focusing on
18 responsible for getting bill through. Just before final vote, they
insert one liner that eliminates competitive bidding and they block
distribution of CBO report that takes into account that change. 60mins
showed drugs from the VA that are 1/3rd the price of the identical
drug under Part-D. They also found that all the 18 republicans, within
6-12 months had resigned and were on drug industry payrolls. the
comptroller general was on program that medicare part-d comes to
represent $40T unfunded mandate ... totally swamping all other budget
items ... and the bill was passed shortly after congress let the
fiscal responsibility act expire.
