re:
http://lnkd.in/Uz6-ck

I remember in the late 90s, some number of NASA (& other gov. labs) turning off mainframes when the last system support programmer retired ... and the labs. couldn't backfill the positions. Part of the issue, it was a time with extra huge strain on available dataprocessing resources between simultaneous legacy Y2K remediation ... and the internet bubble.

there was an ibm internal online conference discussion started in the early 80s about the looming y2k problem ... one of the people at NASA/houston posted the following contribution:
https://www.garlic.com/~lynn/2000.html#email841207

zEnterprise 196 can execute 50BIPs/second
http://www.foxnews.com/tech/2010/09/01/ibm-unveils-worlds-fastest-microprocessor/

Intel Core i7 at 177,730 MIPs/sec (nearly 178BIPS ... more than 3times 80processor 50BIP z196)
https://en.wikipedia.org/wiki/Instructions_per_second

some amount of cloud computing evolved from gov. labs. GRID computing .... in parallel with the large processor clusters at the internet service processors (that were evolving into the mega-datacenters)

this estimate is that there are 10,000 installed mainframes in the world
http://articles.economictimes.indiatimes.com/2010-08-10/news/27620495_1_mainframe-ibm-big-challenge

if you assume all of them have been upgraded to max'ed out 80processor, 50BIP z196 ... then the aggregate mainframe mips would be 500TIPS.

This is an article that Amazon cloud carved out an on-demand supercomputer of 240TIPS ... which would rank as 42nd largest supercomputer in the world.
http://news.cnet.com/8301-13846_3-57349321-62/amazon-takes-supercomputing-to-the-cloud

and half of aggregate total installed mainframe processing power ... assuming every installed mainframe was maximum configured 80 processor, 50BIP z196

total aside ... the news has the reason for the Microsoft "cloud" being down on the 29th ... was because of some software that couldn't handle leap-year. Note in the above referenced NASA/Houston story ... there is something similar from the early age of mainframe

some recent posts in other mainframe threads estimating that some number of the mega-datacenters, individually contain more aggregate processing power than all currently installed mainframes in the world

Why Didn't the Internet Take Off In 1983?
http://tech.slashdot.org/story/12/03/02/0059249/why-didnt-the-internet-take-off-in-1983

The internal network passed 1,000 nodes in 1983 ... something like 4times that of the internet ... but the internet was catching up rapidly ... passing the internal network late 85 or early 86. at the same time there was the univ. bitnet (earn in europe) using similar technology to that used in the internal network

1000 nodes, 1983:
https://www.garlic.com/~lynn/vnet1000.jpg

1000 vnet nodes

bitnet:
https://en.wikipedia.org/wiki/BITNET

old email from person setting up EARN (bitnet in europe):
https://www.garlic.com/~lynn/2001h.html#email840320

NSFNET backbone was the operational basis for the modern internet, old email related to run-up to NSFNET backbone
https://www.garlic.com/~lynn/lhwemail.html#nsfnet

virtual machine was some of the original cloud ... a number of operations started offering online cp67 internally in the 60s and was also the basis of commercial online service bureau operations ... most moving to vm370. one on the west coast was TYMSHARE
https://en.wikipedia.org/wiki/Tymshare
which also had TYMNET for its own POPs
https://en.wikipedia.org/wiki/Tymnet

in aug1976, TYMSHARE started offering its vm370/cms online computer conferencing (free) to (ibm user group) SHARE as vmshare ... archived here:
http://vm.marist.edu/~vmshare
sometimes(?) "404" ... but also at wayback machine
http://vm.marist.edu/~vmshare/

I got blamed for online computer conferencing on the internal network in the late 70s & early 80s. I would also make various other things available internally. One of the issues with making copy of vmshare available internally was arguing with the lawyers about employees being contaminated with exposure to external information ... some old vmshare related email
https://www.garlic.com/~lynn/lhwemail.html#vmshare

as in other references ... I've had home online access since mar1970 starting with 2741 and audio coupler.

One of the issues with internet passing internal network (late '85 or early '86) is that the corporation restricted PCs & workstations connectivity to terminal emulation .... where they were starting to appear as peer-network nodes on the internet.

arpanet had specially constructed IMPs under central maintenance and administrative control. At the big switch-over to internetworking protocol on 1Jan1983, there were possibly 100 IMP network nodes and 250 connected hosts. The 1Jan1983 switchover to internetworking protocol provided for gateway to interconnect different infrastructures ... removing major growth inhibitor. The internal network that had been larger than arpanet/internet from just about the beginning basically had a form of gateway layer in every node ... providing for a lot more local independence and autonomy

the internal network was still not SNA ... which was becoming more&more an embarrassment to the communication group. Eventually there was concerted internal political effort (including some amount of mis-information) ... discussed in some detail in this recent post (along with several other issues):

They didn't triage the S&L either. They "doaged" it a bit, but ultimately it was soft loans for fat cats.

old long-winded post from last century mentioning S&L crisis
https://www.garlic.com/~lynn/aepay3.htm#riskm

it mentions that Citi had been the largest player in the mortgage market during the period, then realized that their ARM mortgage portfolio could take down the institution, sold off the portfolio, got out of the business and required a (private) bailout to stay in business.

later leading up to middle of the last decade, somebody mentioned that some of the same investment bankers that had been into the S&L crisis were also behind much of the internet bubble IPO bubble (i.e. formula invest in company, take it to IPO and get out, preferrably companies then fails, leaving the landscape open for the next round of IPOs) ... and were getting into mortgage back securities.

note that a lot of the investment banking motivation was individual rewards skimming off on the transactions ... leaving the risk consequences to their institutions (economy and/or country).

In the citi case, it would appear that all the institutional knowledge about dangers of ARM portfolio disappears by the time of the recent real-estate bubble ... of the four large too-big-to-fail holding $5.2T in triple-A rated toxic CDOs at the 2008 ... Citi was holding more than the other three.

http://www.bloomberg.com/apps/news?pid=newsarchive&sid=akv_p6LBNIdw&refer=home

of course the triple-A rated toxic CDOs were being held "off-book" ... on the investment banking side ... courtesy of GLBA, repeal of Glass-Steagall and the safety&soundness of regulated depository institutions being able to have unregulated, risk investment banking arms. Citi had recently been taken over and the new CEO was instrumental in GLBA repeal of Glass-Steagall:

somewhat family affair:

Gramm and the 'Enron Loophole'
http://www.nytimes.com/2008/11/17/business/17grammside.html
from above:
Enron was a major contributor to Mr. Gramm's political campaigns, and Mr. Gramm's wife, Wendy, served on the Enron board, which she joined after stepping down as chairwoman of the Commodity Futures Trading Commission.

... snip ...

and an older article: Phil Gramm's Enron Favor
https://web.archive.org/web/20080711114839/http://www.villagevoice.com/2002-01-15/news/phil-gramm-s-enron-favor/

from above:
A few days after she got the ball rolling on the exemption, Wendy Gramm resigned from the commission. Enron soon appointed her to its board of directors, where she served on the audit committee, which oversees the inner financial workings of the corporation. For this, the company paid her between $915,000 and $1.85 million in stocks and dividends, as much as $50,000 in annual salary, and $176,000 in attendance fees,

and more #3 responsible, Greenspan Slept as Off-Books Debt Escaped Scrutiny
http://www.bloomberg.com/apps/news?pid=20601109&refer=home&sid=aYJZOB_gZi0I

from above:
That same year Greenspan, Treasury Secretary Robert Rubin and SEC Chairman Arthur Levitt opposed an attempt by Brooksley Born, head of the Commodity Futures Trading Commission, to study regulating over-the-counter derivatives. In 2000, Congress passed a law keeping them unregulated.

... snip ...

Brooksley was fairly quickly replaced by Wendy Gramm as head of Commodity Futures Trading Commission, before Wendy then resigned to join Enron's board.

and #4 responsible, head of SEC:
http://www.time.com/time/specials/packages/article/0,28804,1877351_1877350_1877323,00.html

Congress passed Sarbanes-Oxley in the wake of Enron/Worldcom, in theory to prevent such activity in the future. However, it required some enforcement by SEC. Possibly because GAO didn't think that SEC was doing anything they started doing reports of fraudulent public company financial filings ... show uptic even after Sarbanes-Oxley.

A leading edge of both the exploding distributed computing tsunami as well as cluster computing were the 43xx machines.

The follow-on to the 370/168 was 3033 ... which was effectively the 168 design remapped to faster chips ... 370/168 was approx. 3mips processor and the 3033 was approx. 50% faster at 4.5mips (compared to I7 at 177,730mips). A cluster of 4341s was more aggregate processing power than 3033, cost less than 3033, and had smaller environmental footprint. Some of the internal politics with 4341 threat to 3033 was at one point the high-end division managed to have allocation of critical 4341 manufacturing component cut in half.

The small 43xx environmental footprint also resulted in the emerging wave of distributed computing ... with large corporations ordering hundreds of 43xx machines at a time and putting them out into departmental areas. Internally it contributed to scarcity of conference rooms as they were being converted to 43xx.

old email mentioning 43xx machines
https://www.garlic.com/~lynn/lhwemail.html#43xx

43xx machines also contributed to big increase in size of internal network ... recent google+ post

Past posts mentioning doing the corporate HA/CMP product
https://www.garlic.com/~lynn/subtopic.html#hacmp

I had coined the terms "disaster survivable" and "geographic survivable" out doing HA/CMP marketing and at one point was asked to do contribution to the corporate continuous availability strategy document. However, both Rochester and POK complained that (at the time) they couldn't meet the objectives and had the part pulled. misc. past posts mentioning continuous availability

This is reference to Jan92 meeting in Ellison conference room discussing cluster scale-up

the mainframe DB2 group complained that if I was allowed to continue, it would be at least five years ahead of them.

the last email in above:
https://www.garlic.com/~lynn/2006x.html#email920129

was possibly only hrs before the effort was transferred and we were told we couldn't work on anything with more than four processors. A couple weeks later it was announced as supercomputer for numerical intensive market only ... press item
https://www.garlic.com/~lynn/2001n.html#6000clusters1 17Feb1992
and scientific and technical only
https://www.garlic.com/~lynn/2001n.html#6000clusters2 11May1992

Now long ago and far away, my wife had been con'ed into going to POK to be responsible for loosely-coupled architecture ... where she created Peer-Coupled Shared Data architecture ... some past posts
https://www.garlic.com/~lynn/submain.html#shareddata

however, between ongoing skirmishes with communication group about being forced to use SNA for loosely-coupled operation and low uptake (except for IMS hot-standby ... really didn't start seeing for mainframe until sysplex), she didn't stay long.

In more recent years, in discussions with the guy that runs FEDWIRE ... he would comment that major contribution to FEDWIRE's 100% availability was IMS hot-standby (triple replicated at geographic distances):
https://en.wikipedia.org/wiki/IBM_Information_Management_System

the 43xx sold into the same mid-range market as vax ... 43xx sold about same numbers as vax in the single or small orders. big difference for 43xx was the large corporate orders for hundreds at a time. SHARE had report that vm370/4341 somewhat suffered compared to vax/cms ... with vm370/4341 requiring more support effort & skills than vax/vms (note mvs wasn't even a consideration since its support effort & skills was enormously larger)

In the mid-70s, I got called into customer trying to run vm370 on 256kbyte 370/125 (skyscrapper in manhatten) ... which wasn't announced on/or supported. It could run a generated system ... but performance was slow. CP67 would run much better on 256kbyte 360/67 ... but in the morph to vm370 and somewhat adding features adhoc ... the vm370 fixed storage requirements were becoming bloated. I did rework of various pieces of vm370 bloatware getting fixed storage requirements back closer to cp67.

Also shot a microcode bug in 370/125 being able to do native build of vm370. Turns out vm370 initial build process used MVCL with length of 16mbytes to clear storage and determine real machine size at the same time. all 360/370 instructions would first check start and ending storage location before executing instructions. 370 introduced change for "long" instructions which were to execute incrementally a byte at a time. Unfortunately 125 microcode bug would do the precheck and fail the instruction (and vm370 build processes effectively believe it was running on zero storage machine and abort).

Trivia from my undergraduate days. The univ. library had gotten ONR grant to do online library catalog ... some of the money was used to get a 2321 datacell. The project was also selected to be betatest for original CICS product ... and I got tasked to do the CICS support & debug. CICS had originally been developed at customer account and one of the early "bugs" in CICS showed with library using different BDAM options than what the original customer had been using. some CICS/BDAM posts

Back in 1967/8, a colourful customer on the patch to which I belonged was running PCP on a 64K machine and it may have been a 360/40. Our ace young salesman had been responsible for this! IIRC this was considered the opposite of the leading edge but it seemed to work for a while!

While we did have a customer - a university - genuinely at the leading edge with a 360/67, I worked at the crowded lower end among the 360/30s running DOS/360. My first responsibility was assisting a customer with the "free" time converting from a 1400 system to a 360/30 with DOS/360.


the univ. had 709 running tape-to-tape ibsys with 1401 front-end for unit-record (reader->tape, tape->printer/punch, tapes manually transferred between 1401 drive and 709 driver). student jobs ran in under second elapsed time.

univ. was sold a 360/67 for tss/360 to replace 709/1401 combo. As part of the transition, the 1401 was replaced with 64kbyte 360/30 ... which could run 1401 emulation and the front-end unit record 1401 MPIO application.

I got a student job re-implementing MPIO on 360/30 (possibly as part of univ. preparation moving to 360) and got to design my own monitor, my own device drivers, interrupt handlers, scheduling, storage handling, etc. I eventually had a 2000 card (box of cards) assemble program ... with assembly option to either run stand-alone or under OS/360 PCP with five DCBs. The stand-alone version took approx. 30mins elapsed time to assemble (early os/360 PCP) while the OS/360 version took approx. an hour to assemble (each DCB macro assembly processing taking over five minutes elapsed time).

I would get the datacenter all to myself on the weekend from 8am sat until 8am monday ... 48hrs w/o sleep made it little hard going to monday classes.

The 709&360/30 was eventually replaced with 360/67 and since tss/360 wasn't yet ready, it ran as 360/65 with os/360 ... initially the "same" student fortran jobs taking over a minute elapsed time. This was cut approx. in half with move to HASP and MFT. I was given responsibilty for the operating system ... and starting with OS/360 release 11 doing highly customized STAGE2 sysgens under the production operating system. I would carefully rework output of STAGE1 sysgen ... so it could run in the production operating system ... and that the allocation and move/copy steps carefully organized to optimize disk arm seek operation (location of datasets on disk as well as location of members within PDS). This gave me approx. three times additional speedup in 3step fortgclg for student jobs ... but still 13secs elapsed time (mostly job scheduler overhead)

This is old post with some results that I presented at fall68 SHARE meeting in Atlantic City (univ. had also gotten copy of cp67 in Jan68 and let me play with it on the weekends, I rewrote large pieces cp67 during the spring and summer ... which is also included as part of the presentation)
https://www.garlic.com/~lynn/94.html#18

later univ. got waterloo's watfor (for student jobs), big speedup was eliminating job scheduler overhead for tray of batched student jobs ... the job scheduler overhead to start single-step watfor was still longer than the time it took watfor to process a whole tray of student jobs (typically around 2500 cards, 50-100 student jobs) ... but finally the 360/67 throughput was more than the 709.

Time to pull the PIN!

Blog: Financial Crime Risk, Fraud and Security
Time to pull the PIN!
http://www.finextra.com/community/fullblog.aspx?blogID=6299

Static data and skimming/evesdropping/harvesting as long been known to be problem.

One of the assumptions stronger secruity with multi-factor authentication ... is that the different factors have independent compromises/failure-modes. PINs represented a countermeasure to lost/stolen magstripe cards (although one study found 1/3rd of magstripe cards had the PIN written on them).
https://www.garlic.com/~lynn/subintegrity.html#3factor

In the case of skimming exploits (possibly from at least late 80s) ... all forms of static data, magstripe & (shared-secret) PIN ... could be skimmed at the same time ... invalidating the assumption about different factors having independent compromise/failure-modes (note there is operation difference between share-secret PIN and a PIN that is never shared)

We had been called in to consult with small client/server startup that wanted to do payment transactions on their server, they had also invented "SSL" they wanted to use; the result is now frequently called "electronic commerce". Somewhat as a result, in the mid-90s we were invited to participate in the X9A10 financial standard working group which had been given the requirement to preserve the integrity of the financial infrastructure for *ALL* retail payments. As part of the effort, we looked at detailed, end-to-end threats and vulnerabilities of different payment mechanisms to come up with the X9.59 payment standard. reference
https://www.garlic.com/~lynn/x959.html#x959

Part of the X9.59 was eliminating static data and also slightly tweaking the payment paradigm eliminating the threat from traditional evesdropping/skimming/harvesting data breaches (it didn't eliminate the activity ... just made the information useless to the crooks in performing fraudulent financial transactions).

Note that the preoccupation with multi-factor authentication as countermeasure to lost/stolen card ... shows up in (other) new solutions from decade ago, that were still quite vulnerable to any kind of skimming/harvesting/evesdropping ... where it is found to trivially counterfeit card from harvested information (reference to presentation on yes card at cartes 2002 ... gone 404 but lives on at wayback machine):
https://web.archive.org/web/20030417083810/http://www.smartcard.co.uk/resources/articles/cartes2002.html

when the details of yes card exploits were presented to the ATM Security task force in 2003 .... it prompted somebody in the audience to proclaim that they managed to spend billions of dollars to prove that chips are less secure than magstripes. past posts
https://www.garlic.com/~lynn/subintegrity.html#yescard

Another generation of static data evesdropping/skimming/harvesting is discussed here:

Mythbusters Banned From Discussing RFID By Visa And Mastercard
http://www.disinfo.com/2012/02/mythbusters-banned-from-discussing-rfid-by-visa-and-mastercard

previously mentioned in the past:
https://www.garlic.com/~lynn/2012b.html#55 Mythbusters Banned From Discussing RFID By Visa And Mastercard

There are actually two aspects ... one is the static data characteristics ... which is shared by (at least) both PINs and passwords ... but there is the other aspect that they are shared-secret authentication. The issue for shared-secret authentication ... is that it requires a unique value for every security domain (as countermeasure to cross-domain exploits)... which has led to the explosion in PINs and passwords. Further aggravating the situation for shared-secret authentication is frequent requirement that they be impossible to guess ... which then results in them being impossible to remember ... necessitating that they all be written down (creating its own vulnerability)

Foreclosure settlement a failure of law, a triumph for bank attorneys
http://www.washingtonpost.com/foreclosure-settlement-a-failure-of-law-a-triumph-for-bank-attorneys/2012/02/23/gIQAe7feaR_story.html

from above:
Before the settlement, we learned that nearly every aspect of the robosigned documents was false. None of the details were ever reviewed. The signatures attesting to the review of the documents were fabricated -- made by someone other than the person whose name was on the document. Neither person -- the supposed signatory to the document nor the hired forger -- ever validated the facts of each case. All of the safeguards put in place to make sure foreclosures were done correctly and legally were bypassed. Even the notary stamps were bogus -- they were not real, and not signed by a notary to validate that the signer and the signature matched.

from above:
The mortgage settlement by State attorneys general marks a new low for America. A massive criminal conspiracy -- the Mortgage Electronic Registration Systems (MERs, see Wikipedia), plus large-scale perjury ("robo-signing" foreclosure papers) and fraud before our courts. All settled with a slap on the wrist to the banks. It teaches large corporations thay they lie beyond the law, a large step beyond the traditional lax enforcement of laws against big businesses.

The Foreclosure-to-Rental Boondoggle

from above:
The reason that housing prices have dipped only 33.6 percent in the United States instead of 60 percent as they have in Ireland, is because the big banks have been keeping inventory off the market. If the millions of homes -- that are presently headed for foreclosure -- were suddenly dumped onto the market, prices would plunge and the biggest banks in the country would be declared insolvent

One year ago, the largest financial institutions on Wall Street were desperate to show off their strength by paying out, or raising, dividends for the first time since the Great Recession. After conducting a secretive test of the banks' health, the Federal Reserve granted most of their requests in March 2011 -- over loud objections from economic luminaries in Washington and across the country. Now, for the first time, we tell the story of why the Federal Reserve caved, and how Wall Street still owns the place.

Bankruptcy would be the best option, except that our system would then sell it to some other huge bank so they could get even bigger. Break it up into geographic pieces and sell the pieces separately.

NationsBank

In 1998, it acquired BankAmerica Corporation of San Francisco in what was the largest bank merger in American history at the time. NationsBank was the nominal survivor, and the merged bank was (and still is) headquartered in Charlotte. However, the enlarged bank took the Bank of America name, and operates under BankAmerica's charter.

a couple miles from SLAC, east on Page Mill, towards El Camino and then one block north was vm370-based HONE system that provided world-wide sales&marketing support for IBM (or east on Sand Hill, south on El Camino to California)

and a couple miles from both was TYMSHARE which had online commercial vm370 timesharing service. It had offered its vm370/cms based online computer conferencing (free) to SHARE starting in Aug1976 as vmshare ... archived here:

VM TCP/IP stack was written in vs/pascal but had some performance issues getting about 44kbyte/sec using 3090 processor. I did the changes to support RFC1044 and in some performance tuning at Cray Research got 1mbyte/sec (channel media) thruput between 4341 and Cray using only modest amount of 4341 (possibly 500 times improvement in bytes moved per instruction executed). some past posts

later vm tcp/ip was ported to MVS (and released as standard MVS product) by providing emulation for necessary VM functions in MVS environment.

I've mentioned before that I was blamed for online computer conferencing on the internal network (folklore was that when the executive committee was told about online computer conferencing on the internal network, 5of6 wanted to fire me).

This is recent post about making VMSHARE (SHARE online discussion groups) available on the internal network ... and big argument with lawyers about whether exposing employees to external information would contaminate them:
https://www.garlic.com/~lynn/2012d.html#3

computer conferencing reference was late 70s and early 80s ... from ibm jargon (references name given to part of the activity):

Tandem Memos - n. Something constructive but hard to control; a fresh of breath air (sic). That's another Tandem Memos. A phrase to worry middle management. It refers to the computer-based conference (widely distributed in 1981) in which many technical personnel expressed dissatisfaction with the tools available to them at that time, and also constructively criticized the way products were [are] developed. The memos are required reading for anyone with a serious interest in quality products. If you have not seen the memos, try reading the November 1981 Datamation summary.

... snip ...

There are at least as many cases where innovation and new technology create a paradigm change threatening enormous/big money of entrenched vested interests.

Heading into the middle of the last decade ... somebody related that many of the investment bankers that were instrumental in causing the S&L crisis were then in the internet bubble IPOs ... having a formula process of investing, IPO ... and preferring that the companies then fail, leaving field open for the next round of IPOs .... and were then were in the process of moving into mortgage back securities.

Innovation takes hold much easier where there are no entrenched vested interests ... this happens in completely empty/new technology areas ... as well as developing countries where there aren't already established solutions.

For instance OSI has frequently been characterized as more oriented towards entrenched proprietary telecommunication offerings. Internet was viewed as commodity competition. In the late 80s and early 90s, vested interest were backing elimination of internet and the Federal gov. had even issued mandate that internet would be eliminated and everything transition to GOSIP (G-OSI-P).

The above reference meeting of the DC chapter of the internet society had three talks related to community networks ... which is somewhat in opposition to the large corporations that are trying to improve their monetizing the internet

there was article that a lot of US companies were taking gov. stimulus to create jobs ... but disguising the fact that the jobs were overseas (might show specific new jobs in the US but have net loss of jobs for the year ... one of the reasons many companies stopped publishing numbers).

There was also article that ratio of US executive compensation to US worker compensation had recently exploded to 400:1 after having been 20:1 for a long time and 10:1 in much of the rest of the world.

#4 in time's list of those responsible for the economic mess:
http://www.time.com/time/specials/packages/article/0,28804,1877351_1877350_1877323,00.html

for the last decade, SEC has a long litany of doing little or nothing (in cases where there might have been fines, it was mostly for show, being trivial percent of the amounts actually involved). In congressional hearings into Madoff, there was person that had tried unsuccessfully for a decade to get SEC to do something about Madoff. SEC also didn't catch Enron&Worldcom. In theory, as a result congress passed Sarbanes-Oxley ... but apparently because GAO didn't think that SEC was still doing anything ... they started doing reports of public company fraudulent financial filings ... showing uptic even after SOX:
https://www.gao.gov/products/gao-06-1079sp

The explanation was that the fraudulent financial filings boosted executive compensation and even if the filings were later adjusted ... the compensation wasn't corrected (all under the facade of shareholder value).

And with regard to acts like Sarbanes-Oxley and more recent Dodd-Frank ... there are periodic articles referring to Congress as Kabuki Theater ... the legislation might sound good but the reality is frequently quite different.

CCDN 2; ZZZZZ has a virtual machine hooked up to an CCDN - ITIPS cable simulating a remote printer. Virtual machine will receive incoming ITIPS and spool the contents in a file to the appropriate person (must have names/userid correspondence table and some facility for handling names without userids)

"CCDN" was an internal corporate terminal network ... separate from internal computer network.

Then in addition to receive incoming ITIPS as email ... added feature to be able to originate email to ITIPS gateway that is then deliever as ITIPS (although might be email, ITIPS lingered on at locations where either the originator and/or sender had ITIPS access but not email access).

IPSASM is the main module of the IPS package (encryption). VMSG now has mods. to support various security/encrypting options by calling IPSASM. A CRDR will be coming out shortly which will read encrypted files. Also VMSG has new option to support sending ITIPS

VMSG was email client developed in the 70s ... PROFS picked up source for a very early VMSG version for its email function. When author of VMSG offered them a much more enhanced version, they attempted to get the VMSG author fired (group having clamed they had done everything).

...and many shops (mine included) either rewrote parts of IPLTXT (the bootstrap loader for OS/360) to split the nucleus into fast and slow memory, putting the less-used parts in slow memory to free up the hideously expensive "fast" (by that day's standards) memory. That mod turned out to be relatively trivial but AFAIK IBM never picked it up, even (or especially) in LSCS.

I was brought into Boeing in 1969 to set up online cp67 timesharing service ... sort of as part of forming core of Boeing Computer Services ... which was destined to pick up most of the dataprocessing services in the corporation (i was one of the first dozen or so BCS employees ... although the boeing website claims that officially BCS wasn't formed until the following year).

Not LCS ... but re-orged cp67 memory resident fixed kernel into fast & slow ... but the "slow" part was made "pageable"

CP67 had about 80kbyte fixed kernel (plus dataareas required for each virtual machine). I did a "split" of the CP67 into fixed and "pageable" ... aka portions of kernel features that could be paged out when not be used ... and modification of the internal kernel call mechanism that would handle all the page fetch operations.

All internal kernel call&return were via supervisor calls. I ordered the kernel with "below the line" and "above the line" routines ... and a psuedo pageable for the original kernel image. In the call routine ... any address for "above the line" was assumed to be pageable and it would run through translate mechanism, fixed the page in storage and increment the "lock count" ... entering the routine in non-translate mode with the real paged-in address. The return ... if the address was above the line, it would decrement the corresponding "lock count" ... when it went to zero, the page was available for page-out.

The standard cp67 kernel build process started out real card deck (output of all the assemblies of individual modules) fronted by a slightly modified version of BPS loader. The deck would be "IPL'ed", the BPS loader loader would do all its gorp and then enter the loaded image of the kernel. This routine would write the loaded memory to disk ... setup so that when the disk was IPL'ed it would reverse the disk operation and read (instead of write). The BPS loader would also pass a pointer to the loader symbol table (all module entry points) ... so I also added code to copy the loader symbol table to the end of the pageable kernel.

As part of the pageable function, I had to carefully make sure that none of the pageable routines crossed a page boundry ... the major problem was the "console" (cp67 commands) routine was single large routine ... which had to be broken up into smaller chunks no larger than 4kbytes. This required adding additional external symbols ... since the internal command handling was no longer in single routine. This caused the number of cp67 kernel entry symbols to go over 255 ... which was the limit that could be processed by BPS loader. It first took me awhile to diagnose what the problem was (i.e. exceeding the BPS loader limit) and then real gludge to carefully limit the number of external symbols to 255.

I also identified very high use routines ... that were in the "below the line" ... that were straight library in&out calls ... that didn't need the overhead of the function implemented by supervisor call routine (which included a dynamically allocated savearea), I changed to BALR call (and the routines used single fixed savearea in "page0" ... which worked in multiprocessor mode since there was unique page0 per processor).

The BALR changes later made it out in cp67 ... since it was a significant kernel pathlength reduction (performance improvement). The pageable kernel wasn't released for cp67 ... but was picked up as part of the cp67 morph into vm370 (however, w/o the loader table hack). Did find a copy of the source for BPS loader (the only piece of cp67 that wasn't distributed in source) ... and modified the BPS loader source to increase the loader entry table size passed 255 (for the vm370 version).

above thread includes definition from ibm jargon:

bad response - n. A delay in the response time to a trivial request of a computer that is longer than two tenths of one second. In the 1970s, IBM 3277 display terminals attached to quite small System/360 machines could service up to 19 interruptions every second from a user I measured it myself. Today, this kind of response time is considered impossible or unachievable, even though work by Doherty, Thadhani, and others has shown that human productivity and satisfaction are almost linearly inversely proportional to computer response time. It is hoped (but not expected) that the definition of Bad Response will drop below one tenth of a second by 1990.

... snip ...

part of the discussion was the horrible TSO response and significant performance degradation going from 3277/3272 combo to 3278/3274 (although TSO response was so bad that none recognized how much worse the 3274 controller was compared to 3272).

I did vm370/cms that got .11 trivial interactive response (next nearest system with similar load and configuration was more like quarter second) ... and the 3272 controller added .086 seconds ... resulting in .196 response seen by end-user. longer discussion in this post:

When Santa Teresa lab (now silicon valley lab) was bursting at the seams in 1980 ... they were remoting 300 people from the IMS group to offsite building. They had looked at "remote" 3270 for interactive development ... and the IMS group users found it horrible and unacceptable compared to the vm370/cms service they were getting with channel-attached 3270 controllers in the building.

I got roped into doing the channel-extender support for putting remote channel attached 3270 controllers at the remote site (resulting in them not seeing any difference between local and remote site) Recent discussion touch on some of the topic:

OTOH a millisecond glitch on your connection is nothing for e-mail and almost nothing for Web browsing, but can be a disaster for 3270 over VPN. The new and improved TSO reconnect is a HUGE help.

now for internet, it frequently it isn't so much the amount of data ... but the latency for round-trips. HTTP started out as connectionless protocol built on top of tcp reliable session ... with tcp session setup/teardown for every session.

in the mid-90s as webservers started to ramp up ... there was massive scale-up problem. majority of the tcp/ip stack implementations did a linear search of the FINWAIT list (time-out of closed sessions to catch dangling packets) ... originally implemented under assumption that session setup/teardown was relatively infrequent. However the (mis-)use by HTTP (& HTTPS) was resulting in thousands on the FINWAIT list and large webserver processors spending 95% of CPU running the FINWAIT list.

This could be seen in the rapidly increasing number of servers at NETSCAPE ... this was before DNS & router load-balancing ... so needed users to manually select different servers. This continued until NETSCAPE switched to a Sequent server (Sequent claimed it had been doing large commercial unix with 20,000 concurrent telnet/tcp sessions and so had already encountered & fixed the FINWAIT list problem). Eventually the other webserver platform vendors also started to deploy FINWAIT fixes.

The issue in TCP is it requires a minimum of seven packet exchange for session setup/teardown ... and it was effectively being mis-used by the connectionless oriented HTTP(S) protocol. Later versions of HTTP & browsers have attempted to map multiple HTTP connectionless operations over longer-lived TCP session.

The other performance component of more complex webpages ... isn't necessarily the aggregate amount of data involved (although inclusion of multiple jpeg images can be mbyte or more) ... it is that they are multiple different data elements ... each tending to require sequential end-to-end handshake latency. There is continuing work on trying to overlap as many of these operations concurrent to minimize the elapsed time (but taking advantage of higher peak transmission rates).

disclaimer ...

in the 80s, I was on the XTP technical advisery board where a reliable transport protocol was worked out that required minimum of only 3 packet exchange (compared to 7 for tcp). some past posts
https://www.garlic.com/~lynn/subnetwork.html#xtphsp

and

had done the rfc1044 support for mainframe tcp/ip product. Original code was on vm370 (written in pascal/vs) that got about 44kbytes/sec thruput using 3090 processor. In some tuning tests at cray research, I got 1mbyte/sec sustained (channel speed) between cray and 4341, using only modest amount of 4341 processor (possibly 500 times improvement in bytes transferred per instruction executed). This product was later made available on MVS ... by providing emulation for some of the vm370 function. misc. past posts

two of the people mentioned in above meeting later leave and join small silicon valley startup.

After the cluster scale-up work is transferred and we were told we couldn't work on anything with more than four processors, we decide to depart also.

Those two people become responsible for something called the "commerce server" at the startup ... and we get brought in as consultants because they want to do payment transactions on their server; the startup had also invented this technology they called "SSL" they want to use. We spend some amount of time working on what is now called "electronic commerce" ... including something called a "payment gateway" that transfers transactions back&forth between commerce servers on the internet and the payment networks.

Back then WU tried a variety of things to drum up offpeak business, like social greetings. Presumably they were sent at the night letter rate, making use of otherwise idle facilities.

I forgot the details, but some of the promotions they tried in the 1960s seemed a little silly for a large communications company--they were more like what a small neighborhood appliance store would do.

I remain amazed at the number of local town or neighborhood offices they opened in the 1950s. A number of WU operated offices were still around circa 1980, but most were replaced by contracted agents, and almost all retail business was money transfers; which is what the successor company (using the name) focuses on today.

I recall in the 1970s if one was late applying to take the SATs there were instructions in the booklet on filing a request by telegram. [sarc] I'm sure parents appreciated getting the bill for that request; $10+ back then was nothing to sneeze at.

Hardware for linked lists

Bjarne Stroustrup made a similar argument in the last issue of IEEE Computer magazine that crossed my desk. He explained that while linked lists are nominally O(1) for some sorts of variable-length update tasks, modern hardware can make the constant scale factor quite large, compared to using explicit arrays to do the same thing. His example pitted a doubly-linked list against an array for a random insertion and deletion task on integers (yes, dumb), and found that the linked list only got faster for problems larger than 500000 elements (on his laptop.) Not a terribly convincing argument, but there is definitely value in picking the right structure for the job.

many 360/67s had search-list (SLT) instruction RPQ ... courtesy of Lincoln Labs. It was used by cp67 kernel storage management to search link list for matching storage size (link list is ordered via real storage address). lots of data showed search depth be on the order of 500 elements (or greater) and SLT saved on instruction fetch&decode overhead (non-pipeline, non-cache machine) ... but still had to do at least two storage fetches per list element.

even with SLT instruction ... storage management was starting to push 30% or more of total cp67 kernel pathlength (after lots of other kernel instruction paths had been highly optimized).

then a switch was made to cp67 kernel storage management with subpools for most common storage sizes managed with push/pop management strategy. For majority of storage management routine calls ... pathlength droped to 14 instructions and percent of kernel overhead dropped to 2-3%.

both IBM 43xx and vax sold into the mid-range market about equivalent numbers in the orders involving small numbers. the big difference for 43xx were the corporate orders involving large number of machines ... several cases hundreds at a time. This was the leading edge of distributed computing tsunami. Then starting in the mid-80s, the large PC & workstations started to take over the mid-range market and also put a dent in the high-end market. The 4361/4381 were expected to see comparable explosion in sales as 4331/4341 ... but didn't happen. This is old post with a decade of vax numbers, sliced&diced by year, model, us/non-us ... that starts to show the change in the mid-80s (something similar seen by 4361/4381)
https://www.garlic.com/~lynn/2002f.html#0
past email mentioning 43xx
https://www.garlic.com/~lynn/lhwemail.html#43xx

DEC was even more affected by this than IBM ... with IBM going into the red in the early 90s ... but IBM had high-end mainframes that wasn't as badly affected by the decimating of the mid-range ... that took out DEC. The DEC numbers show DEC trying to re-act with micro-vax going head-to-head with PCs ... that had short burst but couldn't compete long term either.

IBM had contributing factor ... in the late 80s, a senior disk engineer got a talk scheduled at the annual, world-wide, internal communication group conference ... and opened the talk that the communication group was going to responsible for the demise of the disk division (which has since come to pass). The issue was that the communication group had stranglehold on the datacenter and disk division was starting to see drop-off in sales with data fleeing the datacenter to more distributed computing friendly platforms (larger PCs and workstations that had taken over mid-range & server). The disk division had come up with several products to address the problem, but they were vetoed by the communication group that had strategic ownership of everything that crossed the datacenter walls. related past posts

The combination had severe downside on IBM in the early 90s going into the red ... and required Gerstner to come in and clean house to "resurrect" ibm.

Apple didn't do chips ... they were part of the leading wave of packaging single chip processors into PCs. My brother was regional marketing rep for Apple and in the early 80s he would come into town and I would get to attend some of the business dinners and argue with the guys responsible for MAC about the design (before the MAC had been announced). At the time, Apple was run on System/38 and my brother had worked out how to dial into the System/38 and track manufacturing and delivery schedules.

There was recent item about when Jobs was called back in to resurrect Apple when it was on the verge of going under ... that Jobs twisted Gates arm into emergency investment into Apple to keep it afloat (comment that m'soft was in apple patent violation to the tune of billions, apple would go under but the patent litigation would drag on for ages ... however, a couple hundred million could avoid all that).

Apple later got somewhat into hardware with its participation in AIM (apple, Ibm, and motorola) and Somerset ... with redoing 801/risc RIOS chipset into 60x single-chip 801/risc processors and power/pc. Note that the power/pc was not only used by Apple but also by the AS/400 that was the follow-on to the S/38 ... that Apple had been using to run the company more than decade earlier. misc. past posts related to 801, risc, romp, rios, power, somerset, etc

cp67 had messaging between users on same machine. Pisa science center modified cp67 to allow software to intercept messages going to user terminal (this also allowed for application to application messaging). This was ported to vm370 internally ... and I included it in my spring 1975 csc/vm distribution that went out to large number of internal datacenters.

slight correction since I obviously got earlier version than 12Aug1975 for my spring 1975 csc/vm distribution

this post includes portion of old SPM document
https://www.garlic.com/~lynn/2006w.html#16 intersection between autolog command and cmsback (more history)

RSCS was able to use SPM (intercept messages going to terminal) and forward them over the network to users on different machines.

some past posts mentioning internal network
https://www.garlic.com/~lynn/subnetwork.html#internalnet
bitnet univ. network used similar technology to internal network, some past posts
https://www.garlic.com/~lynn/subnetwork.html#bitnet
bitnet wiki
https://en.wikipedia.org/wiki/BITNET

The author of REXX used it to implement a multi-user spacewar game ... where it was used to communicate between spacewar clients and the spacewar server ... it was able to leverage the RSCS support to provide for spacewar clients both on the same machine and/or different machines on the internal network. The original spacewar client started out as application that displayed all user status on 3270 screen and took commands from keyboard. Fairly early there were automated players written (sort of early version of automnomous drones) that would beat human players. The spaceware server was then modified to increase user energy use non-linearly as interval between commands dropped below human expected threshold ... attempt to somewhat level the playing field.

Note that the "first" multi-user game mentioned in the BITNET wiki was years after the internal multi-user spacewar game.

I also included my "autolog" command in the spring 75 csc/vm ... I had originally developed for automated benchmarking ... being able to start synthetic workload scripts to do large different kinds of loads. This was quickly adopted for also automated bringup of service virtual machines (original version of whats currently called virtual appliance) ... complementing service virtual machines to "accept" commands & control via SPM.

I had also been blamed for online computer conferencing on the internal network in the late 70s and early 80s (folklore is that when the executive committee was informed of online computer conferencing and the internal network ... 5of6 wanted to fire me). Somewhat as a result, a researcher was paid to sit in my office for nine months and take notes on how I communicated (they also went with me to meetings). They also got copies of all my incoming and outgoing email and logs of all instant messages. The result was research report, a Stanford PHD thesis (joint between language and computer AI), and material for some number of papers and books. misc. past posts mentioning computer mediated conversation

There was comment that decade ago ... the various investment banking players looked at the situation and figured that could skim off enormous amounts and be long gone from the position by the time there was any reckoning (becoming an institution and coutry problem and they have just walked away).

another example/analogy was regulators encouraging banks to go for racetrack speed record (reckless behavior & heavy leverage) as fast as possible on the straight-a-way ... and even tho they've always crashed going into the curve ... not to worry since the US taxpayer will always make them whole.

Can SSL Certificate Checking System Be Saved?
http://www.informationweek.com/news/security/vulnerabilities/231300216?cid=RSSfeed_IWK_security

from above:
Google says Web certificate revocation checking system is broken, joins other browser vendors at RSA to discuss solutions.

... snip ...

at annual acm (database) sigmod meeting in san jose (circa 1992), in main session, somebody in the audience asked what was all this x.5-hundred stuff was about ... and one of the people on the stage characterized it as a bunch of network engineers attempting to re-invent 1960s DBMS technology.

disclaimer: in the early 90s, we were brought in as consults to small client/server startup that wanted to payment transactions on their server; they had also invented this technology they called "SSL" they wanted to use; the result is now frequently called "electronic commerce". During the audit and review of "SSL" as well as the CA business players ... we come up with a number of deployment requirements ... that were almost immediately violated. That was about the time I originated the term comfort certificates to try and differentiate sense of comfort from real security. misc. past posts on the subject
https://www.garlic.com/~lynn/subpubkey.html#sslcert

somewhat as a result of the work on "electronic commerce", in the mid-90s we were asked to participate in the x9a10 financial standard working group that was given the requirement to preserve the integrity of the financial infrastructure for ALL retail payments. X9A10 activity included looking at end-to-end threat & vulnerabilities of broad range of different kinds of retail payments (point-of-sale, face-to-face, unattended, internet, etc) and came up with X9.59 ... some references:
https://www.garlic.com/~lynn/x959.html#x959

which allows for strong public key authentication w/o requiring digital certificates. Part of x9.59 was slightly tweaking the payment paradigm to eliminate any need to "hide" transaction information in order to provide security (transaction information in transmission and in databases can be fully divulged w/o risk of leading to fraudulent transactions). As side-effect, it eliminated the major use of SSL in the world today.

A contributing factor to certificate-less x9.59 transaction was that appending digital certificate on every payment transactions ... besides being redundant and superfluous ... also would increase the typical payment transaction payload size by 100 times (for no useful purpose) ... some past posts

Note that part of IBM issue was that native processors were pretty much unique to each 360 & 370 model ... so that was huge proliferation of different, incompatible processors ... each requiring their own infrastructure. Something similar was embedded processors ... 3830 disk controller was horizontal microcode engine (much more difficult to program ... also tended to be found in high-end 370 processors) ... but move to much slower vertical microcode (JIB-prime) for 3880 controller. some old posts about being let to play disk engineer in bldgs 14&15

I've periodically mentioned that long ago and far away, my wife was con'ed into going to POK to be in charge of loosely-couple architecture ... where she developed Peer-Coupled Shared Data architecture ... some past posts
https://www.garlic.com/~lynn/submain.html#shareddata

however there was a combination of little uptake (except for IMS hotstandby until sysplex) and ongoing skirmishes with communication group over trying to force her to use SNA for loosely-coupled operation ... she didn't stay long.

Later when we were doing HA/CMP ... we were looking for apps to move to cluster operation (i.e. non-mainframe for loosely-coupled) and there were numerous non-mainframe RDBMS that had done VAX Cluster support. We spent some amount of time with these vendors about migrating their VAX Cluster support to our HA/CMP platform. Based on loosely-coupled and mainframe database experience we had a distributed lock manager ... but to ease porting RDBMS vax cluster support ... needed to add vax cluster compatible API. However, several of the vendors had their top-ten list of how vax cluster had done it wrong (and could be done much better ... especially from the standpoint of RDBMS operation). Having started from scratch ... I didn't have to worry about lots of legacy issues and could work from clean sheet. some past posts:

We had also been participating in the Fiber-Channel Standard (FCS) activity since late 80s ... then in the 92 timeframe started to see participation from POK channel engineers attempting to do extremely unnatural things to FCS in order to create FICON.

ESCON had actually been knocking around POK for quite some time before it was released. One of the rs6000 engineers took specification ... improved bandwidth by about ten percent and used different driver technology that significantly reduced the cost ... and allowed it to be full-duplex ... more than doubling aggregate thruput (before escon was released) ... but incompatible with escon and anything else on the market. He then wanted to do an 800mbit version ... but we convinced him instead to work on FCS ... as interoperable industry standard. misc. past posts mentioning 801, risc, iliad romp, pc/rt, rios, rs/6000, power/pc, etc

the spacewar client and server were writtin in (mainframe) pli ... I have some version of the client MFF2 PLI (but not the assembler subroutines and/or the server), i can email? ... contact Mike to see if he has more

Note that the MFF client attempted to use the 3270 in full-duplex mode ... updating screen and accepting keystrokes asynchronously ... however the 3270 was actually a half-duplex device ... having a bad habit of locking the keyboard, if you hit any key at the moment the screen was being updated ... and then have to stop and hit the keyboard reset key.

The 3272-controller/3277-terminal pair had much of the electronics in the terminal ... and it was possible to do local hacks. One was a small fifo box ... unplug the keyboard from the head, plug in the fifo box and plug the keyboard into fifo box (some amount of physical engineering since the space inside the terminal was cramped). The fifo box would sense if the screen was being updated and queue any keystrokes ... avoiding the keyboard lock and somewhat simulating full-duplex operation.

The 3274-controller and later 327x terminals moved a lot of the terminal electronics back into the shared controller ... eliminating the terminal hacks ... and also degrading terminal response and performance. recent posts mentioning the issue:

One of the issues that I observed was that the "certificate" model has businesses (certification authorities) making money off the certificates ... most of the other, more efficient model ... lack a champion that sees revenue stream and significant profit. At one point in the late 90s, the CA industry was circulating business plans on wall street showing $20B/annum revenue; $100/person/year.

We had been brought in to help wordsmith the cal. electronic signature legislation ... and the CA industry was heavily lobbying that the legislation mandate digital certificates ... which never happened. some past posts

Lords of Finance: The Bankers Who Broke the World
https://www.amazon.com/Lords-Finance-Bankers-Broke-ebook/dp/B001QIGZEK/
pg.323 (refering to Federal Reserve):
It did in fact succeed in curbing the amount of money going into brokers' loans from banks—between early 1928, when the Board first declared war on brokers' loans, and October 1929, banks cut their loans to brokers from $2.6 billion to $1.9 billion. Meanwhile, other sources of credit—U.S. corporations with excess cash, British stockbrokers, European bankers flush with liquidity, even some Oriental potentates—more than made up for the decline by increasing their funding of brokers' loans from $1.8 billion to $6.6 billion.

Evil Wall Street Exports Boomed With 'Fools' Born to Buy Debt
https://www.bloomberg.com/news/articles/2008-10-27/evil-wall-street-exports-boomed-with-fools-born-to-buy-debt

I've in the past mentioned being asked to HTML'ize Percora Hearings along with href/links between last time and this time .... CDOs this time being equivalent to Brokers' Loans the last time ... and Federal Reserve interest rate controls having similar lack of influence ... because of influx of monery from other sources. And the money from the triple-A rated toxic CDOs being used to fuel the real-estate mortgage market speculation (instead of the stock market).

from Percora Hearings:

BROKERS' LOANS AND INDUSTRIAL DEPRESSION

For the purpose of making it perfectly clear that the present industrial depression was due to the inflation of credit on brokers' loans, as obtained from the Bureau of Research of the Federal Reserve Board, the figures show that the inflation of credit for speculative purposes on stock exchanges were responsible directly for a rise in the average of quotations of the stocks from sixty in 1922 to 225 in 1929 to 35 in 1932 and that the change in the value of such Stocks listed on the New York Stock Exchange went through the same identical changes in almost identical percentages.

We used to run MFT and everyday we changed the partition sizes without an IPL. Now if you are saying to change from MFT to MVT then indeed an IPL was needed, as well PCP to MFT (or for that matter MVT)?

The OS is the "key" issue and indeed VM you can "ipl" an OS and it probably does not require an IPL(machine wise) a virtual machine needs to be brought in .

Maybe I am missing some distinction here.


recent post about vm370 handshaking being done at univ. for MVT
https://www.garlic.com/~lynn/2012c.html#16 5 Byte Device Addresses?

vm370 has function to save an virtual memory image from virtual machine and then restore it using IPL command (using ipl-by-name function) .... sort like checkpoint/restart ... but for system. they identified place in MVT where everything was quiesced and could jump back in ... provided for hot-restart significantly cutting MVT IPL elapsed time startup.

note that one of the customers that had been sold 360/67 was boeing huntsville to run tss/360 ... tss/360 was never fully realize ... and many customers ran machine as 360/65 with os/360. boeing huntsville had 360/67 two-processor multiprocessor configurated to run as two independent single processor processors ... with MVT supporting several 2250M1s and long-running graphic applications. The problem was that MVT had a horrible storage fragmentation with long running applications. As a result, Boeing Hunstsville had modified release 13 MVT to run in virtual memory mode but w/o paging. The virtual memory hardware was used to re-order storage addresses as compensation for significant MVT storage fragmentation associated with long running applications.

This is similar ... but different to the justification for adding virtual memory as standard to all 370s ... and move from MVT to SVS ... discussed in this past post:
https://www.garlic.com/~lynn/2011d.html#73 Multiple Virtual Mmeory

.... part of quote in above:
Evans around. For reasons unknown to me, the TSO group had the flip charts and wallboard zzzzz used. The clincher was the ability to run 16 initiators simultaneously on a 1 megabyte system, taking advantage of the fact that MVT normally used only 25% of the memory in a partition. The resulting throughput gain (compared to real hardware) was substantial enough to convince Bob. It helped that Tom Simpson and Bob Crabtree had hosted an MFT II system TSS-Style and shown similar performance gains. Of course, since CP67 was a pickup group they weren't considered and we had the OS/VS adventure instead.

... snip ...

Simpson and Crabtree had done HASP ... and then Simpson went on to do modified MFT-II implementation using TSS-Style paged-mapped filesystem paradigm called RASP (significant performance advantage over the approach taken by SVS&MVS preseving the OS/360 disk paradigm).

This wasn't picked up and Simpson left for Amdahl where he there was "clean-room" do-over. There was legal action about theft of code (even tho there was no intention of ever using RASP) ... and the resulting court audits only found a couple accidental incidents examples of identical code. a couple old email mentioning RASP do-over:

I have several posts in similar thread (NASA unplugs their last mainframe) in MainframeZone ...
http://lnkd.in/Uz6-ck
... that have a lot of other URLs.

fully configured 80 processor z196 is $28M and rated at 50BIPS (configurations range from $1m-$28m)
http://www.foxnews.com/tech/2010/09/01/ibm-unveils-worlds-fastest-microprocessor/

by comparison this rated intel i7 3690x @3.3ghz at 178BIPS ... the equivalent $103M worth of z196.
https://en.wikipedia.org/wiki/Instructions_per_second

references this for 3690x ... which also includes benchmark of 3690x overclocked to 4.8ghz
http://hardocp.com/article/2011/11/14/intel_core_i73960x_sandy_bridge_e_processor_review/4

i've claimed that numerous of the mega-datacenters, individually have more processing power than the aggregate of all currently installed mainframes in the world.

many of the mega-datacenters are doing white-box blades ... basically their own assembly line for massive compute processing ... close to cost of the components. Some of the early activity along this line was started in the 90s at some gov. datacenters ... including nasa locations.

intel i7 3690x chip goes for $1000
http://ark.intel.com/products/63696/Intel-Core-i7-3960X-Processor-Extreme-Edition-%2815M-Cache-3_30-GHz%29

say <$3k per blade for compute processing of $100m worth of z196? ... even if the blades were $10k ... that would still be 10,000 times the z196 price/performance for numerical intensive.

part of the issue in the MainframeZone thread is NASA needing lots of numerical intensive work

IBM cuts more than 1,000 U.S. Workers

https://www.garlic.com/~lynn/2012d.html#23 IBM cuts more than 1,000 U.S. Workers

Early 80s, the corporation included 3270 terminals as part of annual budget process ... being treated as scarce resource ... and many parts of the business restricting them to terminal rooms (and requiring VP signoff for person to have 3270 on their desk). Then there was period where there was rapid spreading rumor that a certain senior executive was doing email ... which had domino effect that other senior executives had to do email ... propagating down into upper reaches of middle management. This had effect of the executives and middle-management preempting the 3270 terminal allocation for their desks ... however for majority of the cases ... the 3270 terminal on executive desk was purely for show ... with some assistant actually handling the email. This eventually led to jokes about PROFS menu burned into screen of executives trying to demonstrate they did email ... i.e. logon in the morning and the 3270 sat the whole day doing nothing but the PROFS menu being solidly burned into the screen.

I did a business case showing that 3year amortized monthly 3270 cost was less than the cost of business phone that sat on every employee's desk as matter of course ... and why was vp sign-off required on such a trivial cost item.

This could be seen later ... where managers would preempt brand-new 486 PS2-80 with "large" 8514 screens ... needed for departmental projects ... for their desk ornament ... still being only used for burning PROFS menu into the screen.

from IBM Jargon:

PROFS - profs n. Professional Office System. A menu-based system that provides support for office personnel such as White House staff, using IBM mainframes. Acclaimed for its diary mechanisms, and accepted as one way to introduce computers to those who don't know any better. Not acclaimed for its flexibility. PROFS featured in the international news in 1987, and revealed a subtle class distinction within the ranks of the Republican Administration in the USA. It seems that Hall, the secretary interviewed at length during the Iran-Contra hearings, called certain shredded documents PROFS notes as do IBMers who use the system. However, North, MacFarlane, and other professional staff used the term PROF notes. v. To send a piece of electronic mail, using PROFS. PROFS me a one-liner on that. A PROFS one-liner has up to one line of content, and from seven to seventeen lines of boiler plate. VNET

cp67 had messaging between users on same machine. Pisa science center modified cp67 to allow software to messages going to user terminal (this also allowed for application to application messaging). This was ported to vm370 internally ... and I included it in my spring 1975 csc/vm distribution that went out to large number of internal datacenters.
https://www.garlic.com/~lynn/2006w.html#email750430

this later email has more detailed discussion of SPM (including being superset of various generations & combinations of VMCF & IUCV)
https://www.garlic.com/~lynn/2006k.html#email851017

slight correction since I obviously got earlier version than 12Aug1975 for my spring 1975 csc/vm distribution

this post includes portion of old SPM document
https://www.garlic.com/~lynn/2006w.html#16 intersection between autolog command and cmsback (more history)

RSCS was able to use SPM (intercept messages going to terminal) and forward them over the network to users on different machines.

some past posts mentioning internal network
https://www.garlic.com/~lynn/subnetwork.html#internalnet
bitnet univ. network used similar technology to internal network, some past posts
https://www.garlic.com/~lynn/subnetwork.html#bitnet
bitnet wiki
https://en.wikipedia.org/wiki/BITNET

The author of REXX used it to implement a multi-user spacewar game ... where it was used to communicate between spacewar clients and the spacewar server ... it was able to leverage the RSCS support to provide for spacewar clients both on the same machine and/or different machines on the internal network. The original spacewar client started out as application that displayed all user status on 3270 screen and took commands from keyboard. Fairly early there were automated players written (sort of early version of automnomous drones) that would beat human players. The spaceware server was then modified to increase user energy use non-linearly as interval between commands dropped below human expected threshold ... attempt to somewhat level the playing field.

Note that the "first" multi-user game mentioned in the BITNET wiki was years after the internal multi-user spacewar game.

I also included my "autolog" command in the spring 75 csc/vm ... I had originally developed for automated benchmarking ... being able to start synthetic workload scripts to do large different kinds of loads.
https://www.garlic.com/~lynn/submain.html#benchmark

This was quickly adopted for also automated bringup of service virtual machines (original version of whats currently called virtual appliance) ... complementing service virtual machines to "accept" commands & control via SPM.

I had also been blamed for online computer conferencing on the internal network in the late 70s and early 80s (folklore is that when the executive committee was informed of online computer conferencing and the internal network ... 5of6 wanted to fire me). Somewhat as a result, a researcher was paid to sit in my office for nine months and take notes on how I communicated (they also went with me to meetings). They also got copies of all my incoming and outgoing email and logs of all instant messages. The result was research report, a Stanford PHD thesis (joint between language and computer AI), and material for some number of papers and books. misc. past posts mentioning computer mediated conversation
https://www.garlic.com/~lynn/subnetwork.html#cmc

another (spacewar) old/past post
https://www.garlic.com/~lynn/2010d.html#74

another snippet from MFF PLI:

DCL LINE23 CHAR(80) STATIC INIT ( 'PF7=DOCK/UNDOCK, PF9=FIRE, PF10=WARP, PF11=SHIELD, PF12=HYPERSPACE, PA2=COMMAND.');

the spacewar client and server were writtin in (mainframe) pli ... I have some version of the client MFF2 PLI (but not the assembler subroutines and/or the server), i can email? ... contact Mike to see if he has more

Note that the MFF client attempted to use the 3270 in full-duplex mode ... updating screen and accepting keystrokes asynchronously ... however the 3270 was actually a half-duplex device ... having a bad habit of locking the keyboard, if you hit any key at the moment the screen was being updated ... and then have to stop and hit the keyboard reset key.

The 3272-controller/3277-terminal pair had much of the electronics in the terminal ... and it was possible to do local hacks. One was a small fifo box ... unplug the keyboard from the head, plug in the fifo box and plug the keyboard into fifo box (some amount of physical engineering since the space inside the terminal was cramped). The fifo box would sense if the screen was being updated and queue any keystrokes ... avoiding the keyboard lock and somewhat simulating full-duplex operation.

The 3274-controller and later 327x terminals moved a lot of the terminal electronics back into the shared controller ... eliminating the terminal hacks ... and also degrading terminal response and performance. recent posts mentioning the issue:
https://www.garlic.com/~lynn/2012d.html#19
reference old comparisons in this post
https://www.garlic.com/~lynn/2001m.html#19

I also don't have any of the autonomous players that were done. ...

not apl, there was adventure
https://en.wikipedia.org/wiki/Colossal_Cave_Adventure

fortran on pdp10 ... tymshare got copy at stanford and brought it over to their pdp10 and somebody at tymshare ported to their vm370. I was in the process of getting copy from tymshare when I got a copy over the internal network from location in europe.

I made executable available internal and if somebody got all points, i would send them a copy of the source.

The PDP1 space-war at MIT
https://en.wikipedia.org/wiki/Spacewar!

was completely different from the multi-user spacewar done by the author of rexx for 3270s.

The IBM Cambridge Science Center was formed 1Feb1964 at 545 tech sq
https://www.garlic.com/~lynn/subtopic.html#545tech csc/vm (&/or sjr/vm) posts
https://www.garlic.com/~lynn/submisc.html#cscvm

some of the mit CTSS people went to project mac on the 5th flr of 545 tech sq and some of the people went to the science center on the 4th flr of 545 tech sq.

The science center at 360/40 (with special virtual memory hardware) to do initial version of virtual machines ... cp40 ... reference ... presentation on cp40 done at 1982 SEAS
https://www.garlic.com/~lynn/cp40seas1982.txt

and also a 2250-M4 ... basically 2250 with 1130 computers (2250-M1 was 360 channel attached version ... a M1 and M4 were about the same cost ... M4 1130 being used instead of expensive M1 controller and channel interface).
https://en.wikipedia.org/wiki/IBM_2250
and
http://www.bitsavers.org/pdf/ibm/2250/A27-2723-0_2250mod4Descr.pdf

The PDP1 spacewar was ported to the 1130/2250 at the science center. The 2250 keyboard was split in the middle with two players using keys on their half of the keyboard to for operations.

The spacewar done by author of REXX had clients running in CMS virtual machines communicating with the server via SPM ... and could leverage RSCS forwarded SPM to different machines ... resulted in spacewar clients being able to run on different real machines than the spacewar server.

Later when 360/67 (360/65 with virtual memory hardware standard) become available the 360/40 was replaced with 360/67 and cp40 morphs into cp67.

I joined the science center in Feb. 1970 ... and would sometimes bring kids in on weekends and they would play spacewar on 1130/2250.

Note that in the early 70s, took a version of apl360 and ported it to cp67/cms for cmsapl. All the monitor & multi-tasking in apl360 could be completely eliminated and the storage management had to be redone for virtual memory environment ... aka apl360 completely swapped 16kbyte workspaces ... the apl360 strategy for constantly touching every available workspace address wasn't painful in apl360 ... but caused enormous problems with virtual machine sized workspaces running in a demand page virtual memory environment.

An API was also done for cmsapl that allowed access to CMS system services ... this caused lots of push back from APL purists as violating APL. However, the combination of really large workspace sizes and system services API ... opened APL to real world applications.

Science center would also run their CP67 for external access (students/staffs at educational locations around cambridge) as well as other corporate locations. One early big user of cmsapl was the business people in Armonk ... that loaded the most valuable of corporate assets on the cambridge system (extensive detail customer information) and used cmsapl for business modeling. It did require some amount of security to make sure non-authorized people (including non-employees and area students) had access to the most valuable IBM corporate assets. --

Creativity: Anyone Can Learn to Be More Inventive, Expert Says
http://www.sciencedaily.com/releases/2012/02/120209172603.htm

long-winded thread in Greater IBM (closed group) that started with recent layoffs, but wondered into number of areas, pieces archived here:

https://www.garlic.com/~lynn/2012d.html#23 .
https://www.garlic.com/~lynn/2012d.html#37

the most recent has description of much of IBM middle management in the 80s having chosen "To Be" (in Boyd's To Be or To Do choice) with regard to terminals as a status symbol and desk ornament (even preempting them when needed for productive work; in the period there were also references to executives, where their dominant activity was managing their careers). Other parts of the thread talks about much of the company apparently heading blindly to the early 90s & going into the red. One of the snippets from the last entry:

During HA/CMP days ... my wife would periodically remind corporate executives that I had never been wrong ... it wasn't strictly true ... but sufficiently that they were constantly motivated to want to do the exact opposite of anything that I would recommend.

... snip ...

there were several things that contributed to our taking early-out offer in 92 ... and I've commented a number of times in the executive exit interview I was told "they could have forgiven you for being wrong but they were never going to forgive you for being right".

some of the "compromise" scenarios involve situations where culture focus on single variable optimization ... and terms "compromise" & "trade-offs" becomes an attempt to describe multi-variable optimization. currently finishing up "Lords of Finance: The Bankers Who Broke the World"
https://www.amazon.com/Lords-Finance-Bankers-Broke-ebook/dp/B001QIGZEK/

covers world economy leading up to WW1 through the 30s. talks about extremes of deflation leading to high unemployment, but printing money leads to inflation and wipes out the savers.

pg.268:
It seemed as if, thanks to Moreau, France, of all the European countries, had finally hit upon the right recipe for dealing with the financial legacy of the war, avoiding the two extremes of German-style inflation and British-style deflation

... snip ...

for other drift, pg.167:
The gold standard had only worked in the late nineteenth century because new mining discoveries had fortuitously kept pace with economic growth. There was no guarantee that this accident of history would continue. Moreover, while the original rationale for a gold standard -- the commitment that paper money could be converted into something unequivocally tangible -- might have been necessary to instill confidence at some point in history, this was no longer the case.

... snip ...

Boyd characterized fighter planes with multiple dimensions ... which led to comparing different fighters as a whole, fighter pilot strategy then became operate in parts of the envelope where your fighter had the advantage and avoid areas where your fighter had the disadvantage (developing tactics oriented towards your relative advantages and disadvantages).

this evolved into being used to design fighters ... somewhat holistically ... but sometimes characterized as compromise or trade-offs. fall back to "flatlanders"
https://www.amazon.com/Flatland-romance-dimensions-Edwin-Abbott-ebook/dp/B0083ZRQR4/

where being able to only see/focus piecemeal fails to appreciate the whole.

As undergraduate in the 60s, i did lot of work on dynamic adaptive scheduling algorithms ... including doing implementations that were picked up and shipped in IBM products. Part of it was something I called "scheduling to the bottleneck" ... i.e. dynamic adjusting scheduling weights according to resources that represented resource throughput bottleneck (basically a different kind of multiple dimension characterizing). some past posts
https://www.garlic.com/~lynn/subtopic.html#fairsare

When prejudices become a disadvantage
http://www.physorg.com/news/2012-03-prejudices-disadvantage.html

common state-of-the-art of the period focused on single dominant resource for scheduling and resource decisions ... which became institutionalized in various sectors of the industry and would dominate for decades. the issue was that over period of decades, the dominance of different resources as bottleneck would shift as specific technology advances occurred.

15 yrs later, I would point that specific technologies had progressed by a factor of 50 ... while other technologies only advanced by less than five times ... radically shifting the relative merits of different technologies & corresponding resources (but numerous sectors of the industry still clung to single-truth that had evolved in the 60s).

Layer 8: NASA unplugs last mainframe

re:

and
https://www.garlic.com/~lynn/2012d.html#35 Layer 8: NASA unplugs last mainframe

the upthread comment was about NASA being numerical intensive oriented. The upthread reference:
https://en.wikipedia.org/wiki/Instructions_per_second

is the "dhrystone" benchmark prorated to the performance of VAX machine from the late 70s as 1MIPS ... as a measure of numerical intensive throughput (aka the measure isn't direct count of the number of instructions but the ratio of the dhrystone benchmark to 1970s VAX machine assumed to be 1MIPS).

The I7-3960x is single socket/chip 8-core (aka processor) doing the benchmark at approx. 4 times the throughput of 80 processor z196 ... or the price/performance for numerical intensive workload is approx. 10,000 times better than the z196 ... regardless of the other specific components of the respective machines and/or what the supposed target market for the components are.

One of the new E5 announcements makes references to 128 "socket" machine ... where a "socket" holds an E5 chip & at 8cores/chip, a 128 "socket" 8-core would be 1024 processor with interconnect needed between sockets/chips. The E5 is possibly only half the numerical intensive thruput of I7-3960x (but starting price at $200/chip in quantities of 1000). Recent reference to Xeon E5 with two 8core sockets/chips
http://www.tomshardware.com/reviews/xeon-e5-2687w-benchmark-review,3149.html
and comparison with i7-3960x
http://www.tomshardware.com/reviews/core-i7-3960x-x79-sandy-bridge-e,3071.html

I've mentioned that the mega-datacenters doing tens of thousands or hundreds of thousands of blades in racks have effectively taken to doing their own manufacturing lines ... producing blades for barely more than their individual component costs (claims are 1/3rd the cost of equivalent brand named blade). These are operations where processing requirements isn't in BIPS, but TIPS (thousand BIPS) and PIPS (million BIPS). One of the things these operations will do is not take the bleeding edge performance component ... but will use chips in the mid-range where overall cost/performance is much better and make it up by having more (but better overall aggregate cost/performance).

Long ago and far away ... they would let me play disk engineer ... misc posts
https://www.garlic.com/~lynn/subtopic.html#disk

The disk labs would get the 2nd or 3rd engineering machine for testing with disks. For awhile I had better access to early 4341 for benchmarking than the 4341 performance test group in endicott had ... so would do benchmarks for them. This is (late 70s) reference to doing national lab "RAIN" benchmark (precursor to dhrystone) on a number of machines. The 4341 was slightly faster than VAX.
https://www.garlic.com/~lynn/2000d.html#0

The 4341 was less expensive, much less physical & environmental requirements, and better performance than 3031. Clusters of 4341 were less expensive, much less physical & environmental requirements and better performance than 3033. At one point the internal politics had the head of POK getting corporate to cut in half the allocation of critical 4341 manufacturing component ... as a way of dealing with the perceived competition. The 4300 significant better price/performance and much reduced physical & environmental requirements also had 4300 machines being deployed out into departmental areas (large corporations ordering hundreds at a time) .. the leading tsunami wave of distributed computing.

part of recent long-winded post
https://www.garlic.com/~lynn/2012c.html#41
in "Old Geeks" group thread
http://lnkd.in/5iXpFi

that spends quite a bit of time on mainframe communication group and a project I had that I called "HSDT" (high-speed data transport) ... some past posts
https://www.garlic.com/~lynn/subnetwork.html#hsdt

and then later when we were doing HA/CMP product ... some of it had evolved from days when we working with LLNL on some serial technology that evolves into the fiber-channel standard (FCS) activity (I've mentioned before that later some of the mainframe channel engineers start participating and doing very unnatural things to the standard in order to be able to support FICON). Some past posts mentioning HA/CMP
https://www.garlic.com/~lynn/subtopic.html#hacmp

a related post regarding ha/cmp and cluster scale-up for commercial applications ... Jan92 meeting in Ellison's conference room (the mainframe DB2 people at the time complained that if it was allowed to continue, it would be a minimum of 5yrs ahead of what they were doing)
https://www.garlic.com/~lynn/95.html#13

other old email related to cluster scale-up work ... some of it turns out being called in to look at NASA requirements to handle data downlink operating at 100megabits/sec continuously and never loosing any data.
https://www.garlic.com/~lynn/lhwemail.html#medusa

within possibly hrs of the last email mentioned in the above (29Jan1992) ... the cluster-scale-up was transferred and we were told we couldn't work on anything with more than four processors. Within a couple weeks it was announced as supercomputer for scientific and numerical-intensive "ONLY" ... press item
https://www.garlic.com/~lynn/2001n.html#6000clusters1 17Feb1992
and another press item later than spring
https://www.garlic.com/~lynn/2001n.html#6000clusters2 11May1992

as an aside, one of the efforts that HSDT was involved in was TDMA communication system that included use of transponder on SBS4 ... and so got invited to the bird going up on 41D.

And recent post
https://www.garlic.com/~lynn/2012d.html#6
in MainframeZone thread on NASA unplugs their last mainframe
http://lnkd.in/Uz6-ck

that talks about some of the same items ... also discussing my wife had been con'ed into going to POK for a stint in charge of loosely-coupled architecture ... where she developed peer-coupled shared data architecture ... some past posts

https://www.garlic.com/~lynn/submain.html#shareddata

which, except for IMS hot-standby, saw little uptake until sysplex. The lack of uptake contributed to her not staying long ... that and the ongoing skirmishes with the communication group attempting to force her into using SNA for loosely-couple operation.

I periodically pontificate about KISS can initially take longer that the complexity that is frequently the result of quick&dirty. The primary difference is frequently that KISS actually requires that you really understand what you are doing.

I've claimed that taking a well-written and tested applications and turning them into a service & business-critical software ... can take 4-10 times the original effort ... and actually requires understanding what you are doing (but doesn't necessarily mean more lines-of-code)

on the other hand their baseline may be the pervasive bloat that is part of the Success of Failure culture

Banks Repaid Fed Bailout With Other Fed Money: Government Report

Banks Repaid Fed Bailout With Other Fed Money: Government Report
http://www.huffingtonpost.com/2012/03/09/bank-tarp_n_1335006.html

I've been doing long-winded posts about this for a couple years

There was interview with Bernanke where he was wringing his hands ... that he was dumping money into the too-big-to-fail for purpose of lending to mainstreet ... but they weren't and he claimed he didn't have authority to force them how to use the money. I'm finishing up reading "The Bankers Who Broke The World"
https://www.amazon.com/Lords-Finance-Bankers-Broke-ebook/dp/B001QIGZEK/
about the crash of '29 and the following depression ... and there were analogous events.

a couple other recent posts:
https://www.garlic.com/~lynn/2012d.html#32 PC industry is heading for more change
https://www.garlic.com/~lynn/2012d.html#40 Strategy subsumes culture

Bernanke shouldn't have been surprised when he pumped $16T into the too-big-to-fail for lending to mainstreet and they didn't do it (needing big stick). When Bush nominated him, one of the qualifications was expert on the Depression and the banks periodically didn't do it then.

http://www.ritholtz.com/blog/2011/12/bailout-total-29-616-trillion-dollars/

almost finished with (from before ww1 thru depression) "The Bankers Who Broke The World" pg439: ... early 1932 ... The two new measures combined -- the infusion of additional capital into the banking system and the injection of reserves -- allowed the Fed finally to pump money into the system on the scale required ... instead of lending out the money used the capital so injected to build up their own reserves. Total bank credit kept shrinking at a rate of 20 percent a year.

http://globalguerrillas.typepad.com/globalguerrillas/2012/03/you-dont-need-a-cyber-attack-to-take-down-the-north-american-power-grid.html

Much of infrastructure grew up designed for the kitchen table with no countermeasures and then internet connections were added (sort of like shoving somebody out the airlock w/o space suit). There is lack of sense of business critical computing as well as extremely large attack surfaces. In the early days, somebody decided to implement signature-based countermeasures and quarantine potential contagions. The list of signatures quickly grew to be significantly larger than the effort required to have reduced the attack surface (aka robust organism with natural defenses).

when I was undergraduate in the 60s, I did lots of operating system stuff, which was picked up and shipped by the vendor ... even getting requests from the vendor. I didn't learn of these guys until much later, but in retrospect ... some of the stuff was of the nature that could have originated from them:
https://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml

another two decades had spread to much of the rest of the gov, from IBM Jargon:

PROFS - profs n. Professional Office System. A menu-based system that provides support for office personnel such as White House staff, using IBM mainframes. Acclaimed for its diary mechanisms, and accepted as one way to introduce computers to those who don't know any better. Not acclaimed for its flexibility. PROFS featured in the international news in 1987, and revealed a subtle class distinction within the ranks of the Republican Administration in the USA. It seems that Hall, the secretary interviewed at length during the Iran-Contra hearings, called certain shredded documents PROFS notes as do IBMers who use the system. However, North, MacFarlane, and other professional staff used the term PROF notes. v. To send a piece of electronic mail, using PROFS. PROFS me a one-liner on that. A PROFS one-liner has up to one line of content, and from seven to seventeen lines of boiler plate. VNET

... snip ...

was platform for PROFS ... note that the PROFS email client had come from internal VMSG ... some old VMSG related email

Reference that worker wages have essentially been flat since the 70s
http://globalguerrillas.typepad.com/globalguerrillas/2011/10/journal-why-the-us-middle-class-is-broken.html

Besides reference to corporations stop publishing add/loss US jobs ... because they had taken stimulus funds to add US jobs ... and it didn't look good if any added US jobs were more than offset by other jobs that were sent over seas ... yesterday/Friday's business news show mentioned that recent american corporate profits are at all-time high (having spent past couple yrs aggressively cuttings costs & employees). The "problem" now is that further profit growth can only come from increasing business (they've pushed cost cutting about as far as it can go)

Also in the financial industry ... some of it is because:

Banks Repaid Fed Bailout With Other Fed Money: Government Report
http://www.huffingtonpost.com/2012/03/09/bank-tarp_n_1335006.html

year or so ago, when Bernanke was asked about the $16T he pumped into the too-big-to-fail for them to lend to mainstreet ... and when they didn't, he just wrung his hands saying he couldn't actually force them. Note that Bernanke shouldn't have been surprised ... when he was nominated, he was touted as expert in the Great Depression ... where something similar happened a number of times.

Note that "age of greed"

We were tangentially involved in the Cal. state data breach notification legislation. We had been called in to help wordsmith the cal. state electronic signature legislation. some past posts

several of the parties were heavily involved in privacy issues and had done detailed, in-depth public surveys ... and the #1 issue was identity theft ... primarily fraudulent financial transactions as the result of compromised sources of prior financial transactions (skimming, harvesting, evesdropping, data breaches, etc). The issue was that little or nothing was being done about the matter ... part of the issue was that the institutions suffering such compromises weren't the victims of the fraudulent financial transactions ... it was their customers (typical scenario is security proportional to risk ... and the institutions weren't experiencing the financial loss). It was then hoped that the publicity from the breach notifications might motivate the institutions to take corrective action.

Since then there have been numerous federal "preemption" notification bills introduced (none yet passed) about equally divided between similar notification requirements and those that effectively eliminate requirement for notifications (in part justified by industry activity like PCI efforts).

For other drift, I was co-author of financial industry x9.99 privacy standard ... part of the effort involved meetings with federal agency behind HIPAA and looking at intersection with HIPAA ... aka financial statements with items for payments to labs that specialize in specific kind of disease or other medical condition testing.

In the cal. state related privacy suveys ... the #2 issue was "denial of service" scenarios ... gov. agencies and other institutions using PII information for denying something (employment, insurance coverage, etc). Again, the institution wasn't the victim ... so it was another instance of the institution lacking any financial motivation to provide security (i.e. as in the financial fraud ... it was the individuals that were the victims, not the institution) ... this was a scenario of attempting to motivate the institutions to protect individuals from being victims by actions (or inaction) by the institutions.

We were brought in as consultants to small client/server startup that wanted to do payment transactions on their server, they had also invented this technology they wanted to use called "SSL"; the result is now frequently called "electronic commerce".

Somewhat as a result of doing work for "electronic commerce", we were asked to participate in the X9A10 financial standard working group that had been given the requirement to preserve the integrity of the financial infrastructure for *ALL* retail transactions (aka all as in face-to-face, point-of-sale, unattended, internet, etc, aka *ALL*). We did several detailed, end-to-end, threat & vulnerability studies of the different kinds of retail payments and came up with the x9.59 standard.
https://www.garlic.com/~lynn/x959.html#x959

One of the things in x9.59 was to slightly tweak the paradigm and eliminate ability to use information from previous transactions to perform fraudulent financial transactions. As a result it would also eliminate the primary use of both "SSL" and "PCI" (primarily attempting to prevent such information from falling into the hands of crooks and thereby eliminating their ability to perform fraudulent transactions; x9.59 eliminated the fraudlent transactions even if they have the information ... so eliminates majority of both "SSL" and "PCI"). some past posts related to current paradigm
https://www.garlic.com/~lynn/subintegrity.html#harvest

We have used a couple metaphors for the current paradigm 1) security proportional to risk and 2) dual-use

1) security proportional to risk metaphor; the value of the transaction information to the merchant is the profit from the transaction, possibly only a couple dollars (for transaction processor, possibly only a few cents). in the current paradigm, the value of the information to the crooks is the account balance or credit limit ... frequently several hundreds to possibly large thousands. As a result, crooks may be able to outspend by a factor of 100 times attacking the infrastructure (as the defenders can afford to spend defending the infrastructure).

2) dual-use metaphor; the same information that needs to be hidden, kept confidential and never divulged is the same information that is needed by dozens of business processes at millions of locations around the world. As a result, we've claimed that if the planet was buried under miles of information hiding encryption, it still couldn't stop information leakage.

... aka x9.59 tweaked the paradigm so it eliminates the dual-use characteristic and the need to hide the transaction information (and there is no longer a fraud threat from information being copied)

from Greater IBM:

& from Facebook
https://www.garlic.com/~lynn/2012d.html#47 You Don't Need a Cyber Attack to Take Down The North American Power Grid

from IBM Jargon:

PROFS - profs n. Professional Office System. A menu-based system that provides support for office personnel such as White House staff, using IBM mainframes. Acclaimed for its diary mechanisms, and accepted as one way to introduce computers to those who don't know any better. Not acclaimed for its flexibility. PROFS featured in the international news in 1987, and revealed a subtle class distinction within the ranks of the Republican Administration in the USA. It seems that Hall, the secretary interviewed at length during the Iran-Contra hearings, called certain shredded documents PROFS notes as do IBMers who use the system. However, North, MacFarlane, and other professional staff used the term PROF notes. v. To send a piece of electronic mail, using PROFS. PROFS me a one-liner on that. A PROFS one-liner has up to one line of content, and from seven to seventeen lines of boiler plate. VNET

expanding cloud computing

Amazon Hails Era of 'Utility Supercomputing'
http://www.pcworld.com/article/251536/amazon_hails_era_of_utility_supercomputing.html

from above:
Amazon in November launched a public beta of Cluster Compute Eight Extra Large (CC2), its most powerful cloud service yet. Every CC2 instance has two Intel Xeon E5 processors, each with eight hardware cores, as well as 60.5GB of RAM and 3.37TB of storage. It communicates with other instances - or virtual servers - in a cluster using 10 gigabit ethernet.

... snip ...

more E5:
http://www.istorya.net/forums/computer-hardware-21/485176-intel-xeon-e5-2690-and-e5-2660-8-core-sandy-bridge-ep-review.html

from above ... two socket (chips) E5-2690, 8cores/chip, 16cores (processors) at 2.9Ghz ... runs 527.55 ... or about eleven and half fully configured 80processor z196 @50BIPS/z196. Then 866 "Amazon CC2" would be equivalent of all estimated installed mainframes (assuming all upgraded to max 50BIPS z196)

more "Amazon CC2"

more IBM support of Xeon E5
http://www.brightsideofnews.com/news/2012/3/7/intel-announces-e5-2600-cpu2c-new-king-of-big-iron.aspx

there is mention of coming E5-4600, four socket (aka @8cores, 32cores aggregate)

older description of Dhrystone "MIPS"
http://www.roylongbottom.org.uk/dhrystone%20results.htm

Note that the "IBM's support of Xeon E5"
http://itcandor.net/2012/03/06/ibm-x86-q112/

gives graph of IBM's server revenue by type (z, x, and power) and quarter from 2004-2011 ... z is still leader ... but presumably there is significant higher profit margin on z than x ... so significantly larger number of "x" systems have to be sold than "z"

However, even IBM's HS23 E5-2600 is only $1815 (with no disks)
http://www.theregister.co.uk/2012/03/09/ibm_xeon_e5_server_lineup/page2.html

IBM specs:
http://www-03.ibm.com/systems/bladecenter/hardware/chassis/bladeht/

Blades 12u high & 12 blades/wide

IBM racks 42u high
http://www-03.ibm.com/systems/x/options/rackandpower/index.html

Which implies could get 36 HS32 E5-2600 blades in single rack ... $65,340 base HS23 price (mega-datacenters have been claiming they mass produce their own blades for about 1/3rd the cost of brand name blades) , and aggregate of over 20TIPS processing power or approx. equivalent 415 fully configured z196 @50BIPS/z196 ... which would cost around $12B.

the other CC2 reference
http://news.techworld.com/storage/3318489/amazon-web-services-adds-supercomputing-service-to-its-cloud/

mentions Amazon is charging $2.40/hr for CC2 (E5-2600 with 60GB memory & 3.4T disk) ... or reserved instance for $4146 & $.54/hr (with one year contract) ... also 290 CC2 are less than $1000/hr ... 167TIPS approx. processing equivalent of 1/3rd of all estimated mainframes in the world (assuming all upgraded to 50BIPS z196)

refers to total size of Amazon cloud (presumably majority are older generation of chips) ... implies avg. 64blades/rack
http://huanliu.wordpress.com/2012/03/13/amazon-data-center-size/

if all 454,400 blades were upgraded to CC2 @2chips/blade = 908,800 chips, @16cores/blade = 7,270,400 cores, @527.55BIPS/blade = 262,416TIPs

with regard to upgrading all blades/racks to CC2, I would expect that they would staged roll-over ... one of the more recent is environmental & power savings from newer generation technology might accelerate roll-over trade-offs. ballpark might be $20k-$50k for the 7000 racks ... say $140M to $350M.

Compare this to upgrading estimated 10,000 mainframes in the world to max. z196 at $29M ... $290B (about 100 times as much) ... which would be approx. 500TIPS aggregate processing power ... compared to above 262,416 TIPS ... about 1/500th ... 50,000 times price/performance difference?

this has mainframe hardware sales running $4B-$6B for the past several years.
http://itcandor.net/2012/03/06/ibm-x86-q112/

with $290B for upgrading all the estimated 10,000 to max. configured z196, at $5B/year ... it would take 58years

the various virtual machine based commercial online services moved up the value chains to provide more information and facilities for them to access (a few notable from the late 60s & 70s were NCSS, IDC, and TYMSHARE). all started at the science center ... 545 tech sq

RAMIS by Mathematica was one of the offerings (by NCSS), a first 4generation language ... being able to generate reports in a few statements that might take hundreds of lines of Cobol.

then NCSS does its own, NOMAD

It was possible to do tech transfer of system/r to Endicott for sql/ds ... "under the radar" ... because the main corporate DBMS effort was all focused on doing EAGLE. Then when EAGLE imploded ... there was big push to do a port to MVS for what becomes DB2.

past posts about (virtual machine based) online services & earlier generation of "cloud computing"
https://www.garlic.com/~lynn/submain.html#timeshare

and from the NCSS Nomad software wiki entry:
NCSS and its time-sharing competitors primarily sold services to large corporations, at a time when most MIS departments were bogged down on huge COBOL implementation projects (see Brooks's famous The Mythical Man-Month for the contemporary mind-set). Because of development backlogs, outside services like NCSS became attractive. Tools like Nomad made end-users self-sufficient: If they had discretionary budgets, and could get the necessary raw data from their MIS departments, then they could solve their own information problems. Many users were content to answer seemingly simple aggregate reporting questions that baffled the MIS departments of the day -- like "rank departments by profitability." Other end-users went beyond basic reporting to build large, mission-critical applications, either by learning the necessary skills, or by hiring their own technicians who didn't report through the MIS hierarchy. NCSS developed a large support infrastructure, including training, consulting, and other services, to foster end-user independence. (Dissatisfaction with traditional MIS methods and resources would later also fuel the personal computer revolution, which in turn would displace time-sharing vendors like NCSS.)

... snip ...

The bottleneck with centralized MIS was also somewhat the rise of the large number of distributed vm/4300 (both within ibm and other corporations) ... before the transition to PCs.

The "doubling" prediction in the mid-80s was to $120B ... primarily based on massive increase in mainframe sales ... and so they had a massive internal construction program for doubling mainframe manufacturing capacities .... even when that business was starting to shift in the other direction. The current $100B is 83% software & services ... with 17% for everything else ... including all kinds of hardware.

There are discussions in a couple of the mainframe groups about NASA turning off its last mainframe. Mainframe Experts
http://lnkd.in/djmeWv
and MainframeZone
http://lnkd.in/Uz6-ck

where I've included reference to:
http://itcandor.net/2012/03/06/ibm-x86-q112/

which shows ibm mainframe sales (2003-2011) running between $4B-$6B ... a far cry from the majority of $120B predicted for the early 1990s (even less when the $120B inflation adjusted is around $250B in today's dollars) ... aka it wasn't exactly career enhancing in the mid-80s to be claiming that the mainframe business was heading in the opposite direction claimed by the executive committee

Total aside, in the early 90s, the US auto industry had C4 taskforce to completely remake themselves ... and since they were planning on heavily leveraging IT technology ... representatives from various vendors were invited to participate. They could accurately characterize the foreign competition, the US problems, and how US needed to remake themselves in order to be competitive ... however, moving forward two decades ... all the major stakeholders resisted any change (offline, I would chide the mainframe brethren about what could they contribute since they suffered from many of the same problems). For other drift ... in the early 80s, there was an article calling for 100% unearned profit tax on the US auto industry. Supposedly the import quotas was to reduce competition, giving the US auto industry enormously increased profits which they were suppose to use to completely remake themselves ... which they just pocketed, continuing business as usual.

related to "electronic commerce" work ... part of it was a "payment gateway" ... some past posts
https://www.garlic.com/~lynn/subnetwork.html#gateway

which handles payment transactions between commerce servers on the internet and the payment networks ... I've also claim was the original SOA (service oriented architecture).

The major theme from the detailed privacy studies was that the top two items (#1 leakage of information from personal financial transactions being copied and crooks doing fraudulent financial transactions and #2 leakage of PII being used by institutions for denial of service) involved copying individual related information in possession of institutions.

The traditional security motivation for an entity is to prevent threats and exploits to the entity. However in both these cases the threats and exploits were against the individual ... not the institutions that needed to secure the information. Since the institutions had nothing at risk ... they hadn't been doing anything. It was then necessary to try and come up with motivation for institutions to protect individual information ... where there wasn't any direct threat to the institution.

Server time Protocol and CICS

The original design of CICS envisaged making elegant use of the announced facilities of OS/MVT. When the time came to implement CICS 1) some of these facilities were not yet available and 2) some of them did not yet work reliably. The implementers of CICS were thus forced to take a RYO approach. They in effect gutted an MFT partition and installed their own functionally MVT-like facilities in it, calling their storage-management interfacing macros GETMAIN and FREEMAIN, etc., etc.

The result was an in many ways a superb table-driven system, one that improved significantly over the succeeding years. Its chief 'defect' was the implementation of its user interfaces as a set of assembly-language macros, which meant that applications run under it had to be written in assembly language. This was 'remedied' in various ways, some elegant and some not, and finally by introducing a 'command'---as opposed to the old 'macro'---level CICS; ultimately it became possible to write CICS APs even in RPG, although these could not be even quasi-reentrant.

The major marketing obstacles to its use by other than assembly-language programmers were thus gradually removed.

In my own doubtless elitist view CICS never fully recovered from these initiatives. They did enable ribbon clerks to write CICS APs, and opinions about whether that was beneficial differ widely.

What is not in my view open to argument is that criticism of the present state of CICS and other such subsystems that is not diachronic is all but certain to be irrelevant.

We are all, ineluctably, creatures of our experience. If you don't know the history of CICS, IMS, DB2, whatever, mug it up if you wish to discuss that subsystem; and stai zitt' until you have mastered it. (Controversy will not thus be eliminated or perhaps even much reduced; equally informed views can, do differ sharply; quaint irrelevance will be reduced).


I've more characterized that pathlengths for os/360 was so enormous that there was no way to do light-weight operations. CICS effectively batched a large percentage of os/360 operations at startup ... and then used its own lightweight versions for actual operation.

Disclaimer: Univ library got ONR grant to do online catalog and used part of the funds to get 2321 datacell. It was also selected for one of the beta test sites for CICS program product (1969) ... and I got tasked for supporting & debugging the deployment. Part of the CICS birthing experience was shooting some number of bugs related to the library choosing different BDAM options than the site where CICS was originally developed. misc. past posts mentioning CICS &/or BDAM

from above:
In the very beginning, CICS attempted to use services provided by the operating system(s) (PCP, MFT and MVT), however it quickly proved to be unacceptable because of the relatively high overhead of those services (CPU cycles and storage consumed with regard to the particular service).

A computer metaphor for systems integration.
http://lnkd.in/K_yWFm

...

Operating Systems and Programming Languages (things used to implement applications) ... try to present paradigms that ease the development of applications (faster, better quality, etc).

This is recent post in a "user-friendly" thread ... touching specifically on both the virtual machine paradigm
https://www.garlic.com/~lynn/2012d.html#51

virtual machine paradigm originated at the science center (4th flr, 545 tech sq) in the mid-60s ... some past posts mentioning science center
https://www.garlic.com/~lynn/subtopic.html#545tech

It also mentions 4th generation languages that evolved on virtual machine platforms in the 70s ... that significantly eased application development (as central corporate datacenters & MIS departments were becoming bottlenecks ... extreme friction).

At the other extreme is I've frequently pontificated that string-handling paradigm in the C programming language have been the source of major security vulnerabilities and exploits ... lots of past posts
https://www.garlic.com/~lynn/subintegrity.html#buffer

Long ago and far away, I was involved in doing a TCP/IP (aka internet) protocol stack implementation in VS/PASCAL language ... which had none of the string-related security vulnerabilities and exploits that have been characteristic of TCP/IP protocol stack implementation in C language. ... for some drift, posts about working with VS/PASCAL implementation
https://www.garlic.com/~lynn/subnetwork.html#1044

This reference to an Air Force security review of another operating system (which was done on 5th flr of 545 tech sq) ... done in PLI language ... and also not found to have any of the security vulnerabilities and exploits that are epidemic in implementations done in C language.
https://www.garlic.com/~lynn/2002l.html#42 Thirty Years Later: Lessons from the Multics Security Evaluation

reference to the 1974 study:
http://csrc.nist.gov/publications/history/karg74.pdf

Old reference to institutions with high security concerns using virtual machine platforms:
https://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml

which I didn't find out about until much later.

There was a little rivalry between the people on the 5th flr and the people on the 4th flr. This is reference to major user (AFDS) of a 5th flr system doing a visit and eventually ordering 210 virtual machine systems (I had transferred to the west coast by this time)
https://www.garlic.com/~lynn/2001m.html#email790404b
in this post
https://www.garlic.com/~lynn/2001m.html#15

In the science center ... we would periodically draw comparison with the productivity of our little group (tended to be in the 30-35 range for much of that period) against the enormous tens of thousands in the mainstream groups ... shows up in Brook's Mythical Man-month.

recent reference to evolution of GML (invented at science center in 1969) to HTML
https://www.garlic.com/~lynn/2012d.html#15

And lots of reference to the internal network ... technology created at the science center
https://www.garlic.com/~lynn/subnetwork.html#internalnet

the "other" co-creator of the "PC revolution's killer app" (aka visicalc/spreadsheets) ... and the person that did the implementation ... had been working at one of the virtual-machine based online service bureaus in the 70s ... and before that at MIT & at 545tech sq. ... and I was at a meeting with him a couple weeks ago.

there are recent observations that Eisenhower originally intended to say military-industrial-congressional complex (MICC) but shorten it to MIC. part of the issue is that MIC is significantly distorted by congressional activity. i've used the paradigm for creation of reference to Financial-Regulatory-Congressional Complex (FRCC) which was behind much of the recent financial mess.

while this refers to $1+T over baseline for the war over the past decade ... it also points out there was an additional $1T over the baseline during the last decade that can't really be explained:
http://www.cdi.org/program/document.cfm?documentid=4623

note cdi.org has moved to
http://www.pogo.org/straus/
... missing $1T is now
http://www.pogo.org/straus/issues/defense-budget/2010/what-did-the-rumsfeld-gates-pentagon-do-with-1-trillion.html

this has CBO showing aggregate $6T reduction in revenues (compared to baseline) coupled with aggregate $6T increase in spending (compared to baseline) over the last decade ... creating $12T budget gap ... really kicked off after congress let the fiscal responsibility act expire in 2002 (baseline had budget surpluses retiring all federal debt by 2010):
https://www.amazon.com/Benefit-Burden-ebook/dp/B005LJEVDM

the enormous federal debt created after the fiscal responsibility act expired in 2002 ... coupled with war draw down ... is putting significant pressure to reduce MICC spending (compared to peak, which included the extra $1T that can't seemed to be explained). Part of the MICC scenario is explained by the strategy for "perpetual conflict" in order to keep the MICC funds flowing ... discussed in "Pentagon Labyrinth"
http://www.cdi.org/program/document.cfm?DocumentID=4639

Other facets are the gold-plated beltway bandits and the spreading Success of Failure culture ... that have determined they take more money off the table with a series of failures than with success. past article:
http://www.govexec.com/management/management-matters/2007/04/the-success-of-failure/24107/

On the FRCC side there is even greater amounts of money slushing around.

another CFTC oil speculation
http://www.thenation.com/article/159078/will-congress-crack-down-oil-speculators

speculators were exlcuded prior to the 19 "secret" letters because they result in wild, irrational price swings. they operate on change & volatility ... they bet on it going up and then pump it ... and then they bet on it going down and they help deflate it.

past articles were that the worst of the oil speculation abuses would be fixed in 2012 ... but that is looking less likely. The congressional rhetoric that led to such expectations was possibly more of their Kabuki theater with little actually what it seems

Note that there have a number of articles in the UK about people are now suppose to report (financial) fraud to their banks ... and the banks will decide whether they report to the authorities. This is in apparent change to "burden of proof" ... where the individual now has to prove they weren't responsible for the transactions ... where before the institution had responsibility to prove it was the individual (as opposed to some crook).

some past Blog entries
http://www.lightbluetouchpaper.org/2007/02/08/financial-ombudsman-on-chip-pin-infallibility/ .
http://www.lightbluetouchpaper.org/2008/01/23/financial-ombudsman-losing-it/

there were some scenarios where the burden of proof was on the individual to prove it wasn't them at the ATM machine ... and needed the bank's ATM surveillance video ... but the bank said it couldn't find the video (compared to when the burden of proof is on the bank and becomes the bank's responsibility to produce the ATM surveillance video ... not the individual).

In one of the cases, I was contacted by email from legal representative of individual involved in such a case.

and this entry gone 404 but lives on at the wayback machine
http://www.moneyexpert.com/News/Credit-Card/18106248/New-rules-to-report-fraud-announced.aspx

from above:
New procedures to report debt will make financial institutions the first port of call for victims of credit card, cheque or online fraud offences, it has been announced.

From April 1st 2007, people in England, Wales and Northern Ireland will be required to bypass the police and go straight to the banks when claiming a fraudulent crime.

It is then up to the financial body to pass the details on to the authorities.

Fans of Threat Modelling reach for their guns ... but can they afford the bullets?
https://financialcryptography.com/mt/archives/001360.html

to throw a monkey wrench into the whole thing ... nominally institutions are doing threat modeling as part of evaluating their risks, leading to (self-interest) taking countermeasures to the risks (a variation on security proportional to risk ... specifically the risks to the institution).

this is a discussion in a linkedin mainframe group about sensitive data
http://lnkd.in/-UcQTJ
and my contributions archived here
https://www.garlic.com/~lynn/2012d.html#49 .
https://www.garlic.com/~lynn/2012d.html#55

the issue is that there is large class of threats involving copying sensitive data ... but where things get short circuited ... the risk is not to the institution ... but to individuals. aka the institutions have no risk. The challenge then was trying to come up with ways to motivate institutions to take countermeasures (where the institutions have no risk and self-interest).

The specific instances was HIPAA (to motivate institutions to protect individual PII information) and data breach notification legislation (possibly indirectly motivating institutions to protect individual financial transaction information).

For other side-track, SSL has been used to hide financial transaction information ... for point-to-point transaction transmission. However, that is trivial portion of the end-to-end transaction business process (especially taken from the standpoint of the elapsed time of the transmission compared to the total lifetime that the transaction information continues to a represent a risk).

As periodically mentioned before, we were involved in deployment of SSL for doing payment transactions on webservers ... now frequently called "electronic commerce" ... nearly 20yrs ago now ... and for almost the whole time I've pointed out that SSL is only trivial part of the end-to-end business process.

and in the theme of "can they afford the bullets" ... another facet of (often repeated over the years) Security Proportional To Risk ... with respect to financial transactions

the value of the financial transaction information to the merchant is the profit on the transactions ... possibly a couple dollars (possibly only a few cents to the transaction processor). The value of the financial transaction to the crooks is the account balance and/or credit limit ... typically hundreds to thousands of dollars. As a result, the crooks can potentially afford to out-spend by 100 times, or more, attacking the system ... as the merchants/transaction-processors can afford to spend defending the system.

this is separate from the fact that exploit risk is to the individual ... not the merchant or transaction processor.

I have a similar jaundiced view of a lot of the threat model stuff in the mid-late 90s ... Lots of parties had the solution (PKI) and they were using the facade of threat models to narrowly focus in portion of problem needing PKI as solution (they had the answer, now they needed to find the question). The industry was floating business plans on wall street $20B/annum for annual $100 digital certificates for individuals. We had been called in to help wordsmith the cal. state electronic signature legislation ... and the industry was heavily lobbying that the legislation mandate (annual, individual) digital certificates.

One of the issues regarding Mhz rate is that currently measuring the latency involved in a cache miss ... measured in number processor cycles ... is around the order of magnitude of a 360 disk access latency (measured in number of 360 processor cycles).

As a result, aggregate processor throughput is becoming more & more sensitive to being able to overlap other work while waiting for fetching data from main storage (cache miss).

RISC processors have done work in this area for going on 30yrs ... combination of things like out-of-order, branch-prediction and speculative execution as well as hyperthreading. As previously mentioned the current generation of "86" processors are all RISC with hardware layer that converts "86" instructions into RISC "micro-ops" for actual execution.

As an aside ... long ago and far away the 370/195 guys came to me to talk about supporting a hyperthreaded multiprocessor implementation. The issue at the time was that the 195 with out-of-order execution overlapped pipeline ... would have throughput of approx. 10MIPs ... but most codes ran around 5MIPs. The issue was the 195 didn't have branch-prediction and/or speculative execution ... the result was that anytime it encountered a conditional branch ... it would drain the pipeline waiting for the condition to be set that controlled the execution sequence. The idea was to simulate to processor execution with two instruction streams feading the pipeline and execution units. The two instruction streams might individual operate at 5MIPs ... because the frequency of conditional branches ... but the combination of two independent instruction streams (each operating at 5MIPs, two instruction streams simulating multiprocessor operation) would keep the pipeline full and the execution units operating at a aggregate throughput of 10MIPs.

Part of e5-2600 throughput improvement (compared to previous generation) is several improvements in all of the related areas ... large amount directed to mask the significant throughput impact of cache miss and having to wait for data to come in from main storage ... aka serialize execution.

Imagine throughput of a large DBMS if it could only perform one disk I/O at a time ... and nothing else could execute while waiting for the disk I/O to complete.

A co-worker that helped me do some internal CMSBACK releases (CMSBACK eventually morphs into customer product as workstation datasave ... which morphs into ADSM and finally now TSM) ... some old email
https://www.garlic.com/~lynn/lhwemail.html#cmsback

leaves and starts doing a lot of consulting work for a chip/vlsi house up valley (that was heavily leveraging vm/370 mainframes ... could trace back to cp67 in the late 60s). He does a port of the AT&T 370 C compiler to CMS (in early 80s AT&T had a effort with IBM to do an AT&T internal-only effort that took at stripped down TSS/370 supervisor and layered higher levels of unix on top), fixed numerous bugs and rewrote the code-optimizer ... all part of porting Berkeley unix-based c-language chip design tools to CMS. He then worked with a C language vendor on release as a product and in the mid-80s ... IBM also offers it as a 370 C language product.

The former co-worker also does work to interconnect the mainframes using ethernet to a large number of graphic workstations being used by engineers in designing chips. The local branch office rep visits one day and asks what he is doing and he explains. The local branch office rep then tells him that he should consider supporting Token-Ring (instead of Ethernet) ... or otherwise they might find that the mainframe service won't be what they have been used to. I then get a call and am forced to listen to an hour of four letter words. The next morning the company has a big press conference to tell the world that they are replacing all their IBM mainframes with SUN servers. IBM then launches a task force to investigate (only) whatever technical issues might be involved in the decision.

as previously mentioned, many of the MIPS ratings are from running dhrystone benchmark and using ratio to VAX thruput (late 70s) as one MIP.

dhrystone may be "broken" ... but it is still being used ... prevous MIPS ratings mentioned upthread:

however, dhrystone benchmark used for e5-2600 MIPS rating (and bunch of other stuff) ... and seems more relavent to the topic of NASA ... which tends to be more computational intensive workload.

FAA 9020 - S/360-65 or S/360-67?

Refed: **, - **, - **, - **, - **, - **, - **, - **
From: lynn@garlic.com (Lynn Wheeler)

Subject: FAA 9020 - S/360-65 or S/360-67?
Blog: IBM Historic Computing
the 360/67 simplex (uniprocessor) was 360/65 with the additional of virtual address translation hardware (8entry associative array) that would do perform virtual address translation ... also had control registers for pointer to segment table.

360 functional characteristics
http://www.bitsavers.org/pdf/ibm/360/functional_characteristics/

http://www.bitsavers.org/pdf/ibm/360/functional_characteristics/GA27-2719-2_360-67_funcChar.pdf

The 360/65 multiprocessor were much like two-processor 370s ... effectively two processors that shared memory ... but everything else was processor specific ... and could be separated into and run as two independent single processors.

The 360/67 multiprocessor had independent channel "controller" and configuration switches ... and was designed for up to 4-processor configuration ... but nearly all that were built were two-processors and one or two 3-processors. The channel director allowed multiprocessor configuration to split into independent single processors (like 360/65) ... but allowed multiprocessor configuration where all processors could access all memory and all channels.
http://infolab.stanford.edu/pub/voy/museum/pictures/display/FAA9020.html

Systems Journal Article ... but they have moved behind ieee paywall
http://domino.research.ibm.com/tchjr/journalindex.nsf/9fe6a820aae67ad785256547004d8af0/720f85f2446ebfc485256bfa00685a26?OpenDocument

this talks about originally a 9020 was six 360/50s .... then configuration upgraded to three 360/65s for compute elements and three 360/50s for i/o control.
http://www.glennsmuseum.com/ibm/ibm.html

my impressions was that the 9020s used 360/65s (not 360/67s) ... presumably the article behind the paywall would have more detail. Since 9020 didn't make use of virtual memory ... there would be no point in using a 360/67 "simplex" (since the only difference with 360/65 was the addition of the virtual memory) ... and the description of the 9020 multiprocessor makes it sound like a different kind of implementation than what was done for 360/67 multiprocessor and channel controller.

unrelated side note ... the original announcement had 60, 62, and 70 ... which was 8byte memory path with 1microsecond memory. There was enhancement to 750ns memory access and the machine models got renamed.

this was first i've heard that 9020 used address translation ... but I have no real information one way or another ... other than the reference to original implementation was a six 360/50 implementation for 9020 ... and upgrade was for three of the 360/50s to 360/65s.

One of the other differences between 360/67 multiprocessor and 360/65 multiprocessor was that 360/67 multiprocessor had multi-ported memory (while 360/65 single processor & multiprocessor and 360/67 single processor all had effectively same memory subsystem).

This can be seen in the increase in memory access time (over 750ns) for 360/67 multiprocessor (360/67 functional characteristic mentioned upthread, pg.30 "access time", pg37 "system data flow", avg. instruction times starting pg.50) ... even in "half-duplex" configuration ... when there is actually only single processor installed. In purely compute intensive environment with no I/O ... the simplex 360/67 should run faster than (nearly identical) half-duplex 360/67 ... however, under heavy i/o loads the reduced memory bus interference could result in half-duplex 360/67 having higher thruput than 360/67 simplex

re upthread bitsavers reference
http://www.bitsavers.org/pdf/ibm/360/functional_characteristics/GA27-2719-2_360-67_funcChar.pdf

ga27-271902_360-67_funcChar.pdf pg.37
In a Model 67-2 system, each CPU and each Channel Controller is connected, with separate bus, to each storage unit in the system. For example, a system with two CPUs and two Channel Controllers has four buses. Each bus can connect to as many as eight storage units. Conflicts that occur among the several buses connected to each storage unit are resolved at the storage unit. Channel Controller requests for storage cycles are give priority over CPU request. Each CPU has a BCU that controls the storage bus with which the CPU is associated. The Channel Controller performs two types of tasks in the Model 67-2 data transfer function: it communicates with the storage units, and it serves the requests from its channels. In a Model 67-1 system, both tasks are performed by the CPU BCU.

The channel data path provides for the transfer of data between the Channel Controller or CPU BCU and the attached channels. The path is eight bytes wide, including the associated parity bits. All data transfers between the BCU and the attached channels is accomplished over a single path; time-sharing of the path is controlled by the BCU. The definition of signals on this path (except signals required for establishing priority among channels) is the same as for signals on the storage bus


... snip ...

refer to figure 8. model 67-1 minium configuration on pg.36 (single memory bus for processor and channel), figure 9. Model 67-2 half-duplex system, minimum configuration on pg 37, and figure 10. model 67-2 duplex system, minimum configuration, pg. 38

... I have no way of knowing ... but might consider that the location of extra frame used in 360/67 for address translation, might also been the location of any extra frame used for the extra 9020 functions.

cp67's cms may have had 32kbytes of code to simulate os/360 system services that allowed various os/360 compilers and applications to execute in the cms environment.

in the morph from cp67 to vm370, some additional os/360 simulation was added as well as some simulation for (optional) dos/360 system services ... but still less than 64kbytes of code. in the mid-70s ... there was some joke that the 64kbytes of os/360 simulation was significantly more cost effective than the 8mbytes of that they used in mvs to simulate os/360 (aka mvs had separate 16mbytes virtual address space for every application ... but 8mbytes was devoted for image of the mvs kernel that occupied every virtual address space).

In this period the vm370 development group had outgrown the space on the 3rd flr of 545 tech sq and moved out to the old (vacant) SBC building in Burlington Mall (SBC had been given to CDC as part of some legal settlement). However, during much of this period was during the Future System era and lots of resources were being spent on various FS activities and lots of 370 stuff was being shutdown.

With the demise of FS ... there was mad rush (all over the corporation) to get stuff back into the 370 hardware and software product pipelines (the delays and lack of products during this period has been used to explain the mainframe clone processors being able to get market foothold). It possibly also explains decision to pickup some of the stuff I had been doing all during the FS period and release it (my periodic ridicule of FS activity also probably wasn't exactly career enhancing). misc. past posts mentioning FS
https://www.garlic.com/~lynn/submain.html#futuresys

Some old email about doing cp67 stuff and then moving to vm370 ... including making highly modified vm370 version available to large number of internal datacenters:
https://www.garlic.com/~lynn/2006v.html#email731212
https://www.garlic.com/~lynn/2006w.html#email750102
https://www.garlic.com/~lynn/2006w.html#email750430

In this period, somebody had been completely reworking the os/360 simulation making it much more complete ... including low level support for actually full access to os/360 formated disks (in addition to mapping numerous kinds of os/360 access methods into cms filesystem operation).

however, in this period, the head of POK also managed to convince corporate to kill vm370, shutdown the burlington mall development group and move all the people to POK (or otherwise he wouldn't be able to meet the mvs/xa customer ship schedule in the 80s). The strategy was to not tell the burlington mall group until the last possible minute ... as part of minimize the number of people escaping the move. Somebody managed to inform the burlington mall group early ... and from then until the shutdown there was a very bad atmosphere in the building as witch-hunt for who leaked the information (fortunately for me, nobody divulged who the source of information was). In any case, there was subsequent joke that head of pok was significant contributor to vax/vms (because so many people escaped the move and went to work for dec). This included the person that had done all the additional os/360 simulation work ... which was lost with no evidence that it every existed.

Endicott was eventually able to save the vm370 product development mission ... but had to reconstitute a development group from scratch (lots of customer comments during the period as to poor quality of vm370 work as the new development group came up to speed).

In the early 80s, there was internal explosion in vm/4341 machines and some large development shops had enormous mvs-hosted development applications ... but were being constrained by central datacenter constraints ... and wanted to migrate to the big proliferation in vm/4341s showing up in every department. One such applications that made extensive use of MVS system services ... was moved to CMS with the addition of 12kbytes of os/simulation. an old email

https://www.garlic.com/~lynn/2012d.html#65

the issue was that 9020 started out with six 360/50s and then three of the "compute" 360/50 processrs (there other three 360/50s dedicated for i/o processing) were upgrade to 360/65.

part of the question was that the 9020 360/65 had an extra "frame" apparently located where the 360/67 extra frame with the address translation hardware ... however, this frame could have instead been where the extra 9020 hardware was located.

a couple references from other posts in the thread:
http://www.ibm360.info/Misc/DATFrame.JPG
and
http://www.ibm360.info/9020%20Complex%20IBM360.JPG

the above shows 7 busses to each storage unit ... with three 360/50 "I/O" processors and four 360/65 (compute?) processors (each having dedicated bus).

another recent item on things raised in above
https://www.garlic.com/~lynn/2012d.html#52 Goldman Exec Quits In A Scathing NYT Op-Ed About How The Firm Abuses Its Clients

a lot of furor generated from the op-ed is to focus on the person writing the as part of obfuscation and misdirection from the issues. there are a couple articles that a few years ago, GS paid the largest SEC fine ever levied, effectively for its culture practices (but could be viewed as part of cost of doing business ... since it is so small compared to amounts involved) ... and supposedly there was new corporate guidelines drafted afterwards to change the culture ... but recent article calls into question whether it was just for show.

topic drift with one of my hot buttons ... KISS ... do detailed end-to-end process threat&risk analysis asking simple questions as who is at risk, what is at risk, what is its value, who are the defenders, what does defense cost, what are the attacks, what is the value/motivation for the attackers, and what are the costs to the attackers. This isn't just doing faster, this is Boyd doing detailed understanding of the factors (not just constantly iterating the loop, but also constantly looking from every possible viewpoint). One of the misuse of KISS is in simplifying OODA to just be faster ... somewhat as a formula for rote learning ... w/o requiring understanding.

This is with respect to the current financial transaction paradigm ... where there are lots of stakeholders that want to preserve the current status quo. discussion from Sat. in financial cryptography blog
http://financialcryptography.com/mt/archives/001360.html
some of my archived comments in the discussion
https://www.garlic.com/~lynn/2012d.html#63

part of the issue is that the entities expected to defend are unrelated to those that are at risk ... so there is little self-interest in doing countermeasures. also any value to the defenders is possibly two orders of magnitude (factor of 100 times) less than the value to the attackers (attackers can potentially afford to outspend the defenders by ten to hundred times)

Real solution is to slightly tweak the paradigm ... but such a change can drastically change the landscape for major stakeholders. This has overlap with MICC and policy of "continuous conflict". In the financial payment sphere, risk&fraud in electronic payments justify significant surcharge payed by merchants to financial institutions (for every transaction; has averaged 40% or more of bottom line for large card issuers). Eliminating the risk&fraud, can be viewed as commoditizing electronic payments and eliminating justification for most of the charges (by at least a factor of ten times, near the actual cost of performing the service). Such a change might result in a 1/3rd hit to the bottom line of many large US financial institutions.

Walmart is notorious for removing costs from infrastructure. In the late 90s Walmart was looking at doing it for the payment infrastructure ... and the financial industry responded with lobbying congress for GLBA. Even though GLBA is now better known for repeal of Glass-Steagall, rhetoric on the floor of congress was that primary purpose of GLBA was to prevent Walmart and Microsoft from becoming banks ("if you were already a bank, you could remain a bank, if you weren't already a bank you didn't get to become a bank"). Roll-forward to the behind the scenes tens of trillions that Federal Reserve provided as its role in the financial mess bail-out; some number of the investment banks that played major role in creating the mess didn't have bank charters ... but the Federal Reserve handed them ones (so they could have access to Federal Reserve assistance) ... theoretically in violation of GLBA (repeal of Glass-Steagall allowed regulated depository institutions to add unregulated, risky investment banking units ... but the "primary" claimed purpose for GLBA would prevent unregulated, risky investment banking institutions to add bank charters).

Mainframe System 370

Mainframe System 370
http://www.forbes.com/sites/davidewalt/2012/03/19/mainframe-system-370/

May '75, Endicott came by to con me in to helping with microcode assist (ECPS) for virgil/tully (aka 138&148) ... old post with more detail
https://www.garlic.com/~lynn/94.html#21

and then the product administrator con'ed me in to running around with him on&off for nearly a year all over the world ... explaining to different country business planners & forecasters 138/148. Then vm370 release3 PLC9 ships with ECPS support at same time as 138/148 ... ann june 1976
http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP3148.html

One of the difference between US & world trade ... is regional US business forecasts had no meaning ... but WT forecasts met that the country ordered the machines ... which were shipped to the country ... and the country had responsibility (US marketing could just ignore whatever they had claimed for forecast).

One of the things that Endicott tried to do was make all 138/148 "vm370" machines ... shipped from the factory (somewhat like LPARS are today) ... but got slapped down by corporate. POK was convincing corporate to kill vm370 product and transfer all the people to POK for MVS/XA (they were planning on waiting to last minute to tell everybody in the Burlington Mall development group that they were moving to POK, the information manage to leak and there is joke that head of POK was one of the largest contributors to VAX/VMS). Endicott eventually manages to save the vm370 product mission but had to recreate a development group from scratch

oh ... there was massive witch hunt in burlington mall to try and find out who leaked the shutdown information ... fortunately for me ... nobody squeeled.

The Myth Of Over-Regulation In The US
http://www.businessinsider.com/chart-the-myth-of-over-regulation-in-the-us-2012-3

from above:
It should be immediately obvious that the U.S. (along with the U.K) is the least regulated advanced economy in the world. This seriously threatens the idea that companies are going to move themselves to a similarly stable country simply because of less business regulation. Particularly not when U.S. employees are the most productive in the developed world

... snip ...

A possible corollary is the extensive use of dark markets w/o transparency and visibility along with claims that large percentage of those currently on wallstreet are psychopaths, lack ethics (of much of the rest of the population) ... and are in significant need of adult supervison.

I'm afraid sequential pre-fetch kinda of makes your point invalid for sequential IO.

when ibm first came out with full-track cache (3880-13/sheriff) ... it advertised a 90% hit rate ... based on 3380 track, 10 records per track and sequential read, where first sequently read on track would fetch the full track ... and then the next 9 sequential reads would already be in cache.

however, if the application when to full-track buffering ... the same exact application and data would go from 90% hit ratio to zero percent hit ratio (effectively each track would be read as a whole, streamed through the 3880-13 cache right into processor memory ... and then wouldn't have any additional cache reference for the track). double "full-track" buffering would then overlap retrieval of the following track with the processing of the records in the previous track (masking disk retrieval latency, aka akin to instruction execution with prefetch &/or out-of-order execution to mask processor cache miss latency).

To look at it another way, cache exists because main storage is very slow compared to the processor speed. Without cache, the processor would not be able to execute instructions nearly as fast as it could. Cache allows data from main storage to be kept very close to the processor in extremely fast memory, allowing the processor to execute instructions as fast as possible.

there have been observations that the latency of a cache miss (elapsed to retrieve data from main storage), measured in number of "processor cycles" is on the order of the 60s disk access ... measured in number of 60s processor cycles. the effort in the 60s to improve throughput was to have multitasking and/or multithreading ... be able to switch to some other work ... while waiting for disk accesses.

a lot of work was done in this area starting in the 80s ... especially for risk processors, for out-of-order execution and speculative execution ... allowing execution of other instructions (that had their data in cache) ... while a "stalled" instruction was waiting on cache-miss. The 60s equivalent to not simply trying to make infinite sized storage, as countermeasure to serialized miss latency, but multiprogramming to be able to switch to something else while waiting.

there was work on hyperthreading ... independent instruction streams feeding common execution units ... that while one stalled instruction stream (waiting on cache miss), there could be instruction execution from other independent instruction stream ... basically simulates multiple processors ... but w/o actual double all of the hardware.

possibly one of the original hyperthreading efforts was for 370/195 ... which didn't actually ship. 370/195 was pipelined and allowed out-of-order execution ... but didn't have speculative execution and/or branch prediction ... so conditional branch stalled the processor. Peak throughput of 195 was approx. 10mips ... but most codes only got 5mips because of abundance of conditional branches. The 195 hyperthreading effort was to simulate multiprocessing with two instruction streams, PSWs, registers, etc ... but not twice the hardware (instructions in pipeline would have one flag bit indicating which instruction stream it was associated with). Two (simulated multiprocessor, independent) instruction streams ... each executing in the pipeline at 5mips (because of stall waiting for conditional branches) ... would be able to keep the execution units operating at effective throughput of 10mips.

One of the issues of current and past several generation of "86" ("CISC") chips ... are that they are actually RISC chips ... with a hardware layer translating the CISC instructions into RISC micro-ops for actual execution. This has resulted in significantly closing the MIP thruput rate of CISC vis-a-vis traditional RISC.

The current generation of chips have cache sizes larger than the 60s processor memory sizes. However, the relative performance degradation of a cache miss today is about the same as virtual memory page fault from the 60s. Some applications today are tuned to maintain their "working set" in cache (and minimize cache misses) ... in much the same way that virtual memory apps in the 60s were tuned to maintain their working sets in real storage (and minimize page faults).

The science center ... some past posts
https://www.garlic.com/~lynn/subtopic.html#545tech

besides having done a lot of virtual memory with (virtual machine) cp67 in the 60s and early 70s ... also did a lot of work with performance monitoring, performance simulated, and workload profiling (some of which then evolved into capacity planning). Science center also did a lot of paging algorithm and paging simulation work. One such was full instruction trace that was then fed into paging simulator ... that also had support for doing semi-automatic program re-organization to optimize operation in virtual memory environment. This was eventually released as a product called VS/Repack in 1976. However, even before it was released, internally a lot of products made extensive use of it to improve their operations ... including a lot of OS/360 applications, subsystems, and products making the transition to "virtual storage" environment.

Some of the high-use, performance sensitive applications do something similar today ... but from the standpoint of improved throughput in a processor cache environment (i.e. today's cache has become the 60s real storage for 60s virtual memory page fault systems)

For a total different take ... there have been some current high-throughput processors done w/o caches ... but with something like 128 "hyper-threads", aka 128 independent instruction streams (simulated multi-processors) ... that while the processor execution is stalled waiting for data from other threads ... the hardware is able to switch to some thread that has instruction with data ready for execution (think of it as hardware multiprogramming and hardware WAIT/POST and its own dispatch/scheduling)

re:

not 50s, but this old post on dual i-stream 195 keeping execution units fed:
https://www.garlic.com/~lynn/2004e.html#1 A POX on you, Dennis Ritchie!!!

in a.f.c. news group ... references the 1-bit flag in the pipeline as red/black instruction streams (as part of common pipeline keeping track of which instructions/registers were associated with which instruction stream) ... and believing it appeared in IBM's ACS project from early 60s ... but I can't find any mention at ACS reference site (IBM Advanced Computing Systems -- 1961 - 1969)
https://people.computing.clemson.edu/~mark/acs.html

however above does mention ACS and out-of-order instruction execution that appears in 360/91.

Part of the current environment is deep-pipeline, dual instruction streams, out-of-order execution, speculative execution (re: conditional branches) and decomposing into RISC micro-ops ... provides execution units with a queue of large tens of pending operations for execution ... and if some operation stalls with a cache miss (and requires latency of storage fetch) ... there are a large number of other pending operations that may be executed (helping mask cache-miss, main storage fetch delay/latency).

ACS timeline
http://www.cs.clemson.edu/~mark/acs_timeline.html

as in above timeline Amdahl resigns from IBM sept. 1970 ... supposedly as result of decision not to do ACS.

Claims have been that Amdahl was not aware of the subsequent "Future System" effort that was going to completely replace all 370 ... but at a seminar he gave at MIT in the early 70s (several of us at the science center attended), he was asked what justifications did he use with investors for his new clone company. He mentioned that customers had already invested billions of dollars in 360 software development, and even if IBM were to completely walk away from 360(/370), that software base would keep him in business until the end of the century (which could be claimed to be a veiled reference to "Future System"). misc. past posts mentioning Future System
https://www.garlic.com/~lynn/submain.html#futuresys

for more topic drift ... additional Future System details:
https://people.computing.clemson.edu/~mark/fs.html

This claims motivation for Future System effort was clone controllers:
https://www.ecole.org/en/session/49-the-rise-and-fall-of-ibm
https://www.ecole.org/en/session/49-the-rise-and-fall-of-ibm

from above:
IBM tried to react by launching a major project called the 'Future System' (FS) in the early 1970's. The idea was to get so far ahead that the competition would never be able to keep up, and to have such a high level of integration that it would be impossible for competitors to follow a compatible niche strategy. However, the project failed because the objectives were too ambitious for the available technology. Many of the ideas that were developed were nevertheless adapted for later generations. Once IBM had acknowledged this failure, it launched its 'box strategy', which called for competitiveness with all the different types of compatible sub-systems. But this proved to be difficult because of IBM's cost structure and its R&D spending, and the strategy only resulted in a partial narrowing of the price gap between IBM and its rivals.

... snip ...

Ferguson & Morris book, "Computer Wars: The Post-IBM World", Time Books, 1993, mention that distraction of Future System and killing off work on 370 products ... and then after Future System was killed with delay in getting 370 efforts restarted, allowed clone processors to gain market foothold.

some discussion of restarting 370 efforts (3033 & 3081)
http://www.jfsowa.com/computer/memo125.htm

for other topic drift ... as undergraduate in the 60s, I had extended cp67 terminal support to include tty/ascii ... and tried to do something with the 2702 terminal controller that it couldn't quite do. This was somewhat behind university effort to do a clone controller (started with an Interdata/3 minicomputer) that would (at least) support both automatic terminal type identification as well as automatic line speed identification. this is picked up as product and sold as clone controller by Interdata (later bought by Perkin-Elmer and marketed under their brand name) ... four of us at the univ. get written up as responsible for (some part of) clone controller business. misc. past posts

With HDS Arrays the sequential pre-fetch buffering is based on the stripe length of the underlying parity group and the data length of the start SSCH that triggers the sequential pre-fetch staging and monitoring.


re:
https://www.garlic.com/~lynn/2012d.html#72 megabytes per second

main difference 3880-13 and 3880-23 was increase in cache size from 8mbytes to 32mbytes ... i don't remember -23 controller recognizing sequential and prefetch ... jib-prime used in 3880 controller was relatively slow microprocessor ... and didn't implement a lot of function. sequential pre-fetch strategies have been done for host-systems for applications that are file/application specific operations ... which is not insensitive to concurrent accesses by other applications using shared device (which 3880-23 couldn't differentiate).

I found old email from 1987 about somebody doing sequential read performance test on 3880-23 ... and the data didn't seem to show that 3880-23 was doing preread. There is also a discussion does the 3880-23 wait for address/marker before starting track transfer ... or can it start as soon as head-settle and wrap-around. The discussion was about whether the 3880-23 would mask RPS-miss (which it didn't) and whether 3880-23 would start full-track data transfer into cache as soon as head settled (w/o waiting for address marker) after a seek operation ... even before processing set-sector, any search, and/or even getting to actual data-transfer channel program. Cache operation was also write "store-through" ... aka synchronous to disk ... and no indication that 3880 controller would do its own seek operation (to move to different track for pre-fetch) independent of what was explicit from some channel program.

for other drift, this mentions processor being able to do cache bypass operations .... for instance if the system is doing form of caching with main memory ... until no longer needed ... then it can be redundant when an identical copy is maintained in controller cache (especially when controller cache may be smaller to very little larger than processor cache):

https://www.garlic.com/~lynn/2012d.html#73 Execution Velocity
https://www.garlic.com/~lynn/2012d.html#74 Execution Velocity

at least by 80s, some processors were started to do "store-into" caches (rather than store-through) for additional performance ... store operation happened in cache and write could be done asynchronously at some later point without involving stalling instructions (with store operations).

Issue with disk caches (& "store-into" for later writing as opposed to "store-through") was processor cache&memory data was typically viewed as ephemeral ... i.e. in power failure, changes weren't expected to survive. However, for disk caches ... store-into had to wait until there was (typically redundant) battery-backed &/or flash memory ... since data written to "disk" was expected to survive power failure (would survive in cache until power was sufficient to eventually write to disk).

note that ibm dasd/channel operation use to have peculiar power-failure, failure mode for a long time. data to be written was in processor memory and if power failed in the middle of the write operation ... there could be sufficient power for the disk to complete the write operation ... but not enough to power processor memory and transfer of data to disk. The symptoms was that disk would propagate write with all zeros ... and then write correct error code for the partial zero record (no hardware error condition).

there were even countermeasure system designs through the 80s that all physical records were guaranteed to end in non-zero (systeme) data ... what wouldn't be seen by applications ... as a validity check for power-failure partially valid record with propagated zeros.

FBA drives developed strategy that there was sufficient power and data to always complete a write operation, once it started. Once all CKD DASD migrated to simulation on top of FBA (there hasn't been any real CKD DASD for decades) ... along with various intermediate cache memory ... there problem has been mitigated. misc. past posts mentioning CKD & FBA

However, one of the other principle people involved in ACS went on to do 801/risc (I've claimed the motivation to do an extremely simple risc design was in reaction to the extreme complexity that was part of Future System design). "IBM Advanced Computing Systems 1961-1969" reference:

However, as mentioned in the ibm-main postings as well as upthead in this discussion, recent generations of "86" chips are actually risc processors with hardware layer that translates "86" instructions into RISC micro-ops for execution ... significantly closing the throughput gap between CISC/"86" and RISC.

Part of the overall processor design infrastructure is to create a huge queue of pending executable operations to draw on as part of masking the huge throughput hit when any particular operation is stalled because of cache-miss. This continues the theme that latency for memory access (because of cache-miss), when measured in number of processor cycles ... is comparable to latency for '60s disk access, when measured in number of "60s" processor cycles. The 60s&70s approach was to implement multiprogramming and multitasking as means of increasing aggregate processor throughput (when one operation was stalled waiting for disk i/o).

for other drift ... additional posts in ibm-main ... discussing some similarities between disk cache technologies and processor cache technologies
