the Case-Shiller index now shows that home prices have dropped 7.7% over the last year. OFHEO shows a smaller decline (for a different set of houses). even the NAR today admitted that prices would drop a little this year. Merrill Lynch sees 20% more. Other observers are calling 30%.

easy (irrational?) credit would have added significantly to home price inflation ... one scenario is transition to more restrictive (rational) credit policies, the boom in real estate valuation would have to experience adjustment (deflation) ... back to some level that would correspond to what would have happened if there hadn't been so much easy credit and bad loans.

in the past, when the fed lowered prime, there would be economic stimulus with increased borrowing/loans because of an increase on the demand side (borrowers finding lower rates more attractive).

in the current scenario, there has been so much easy/bad credit ... there is now quite a bit of downward adjustment on the supply side (compared to what it had been; the prime rate previously having represented little or no barrier on either the supply or demand side). it would be very hard for prime rate incentives for the demand side to compensate for the downside adjustment on the supply side (lending institutions adjusting to more rational loan policies).

some of this could also be attributed to individuals on the loan side ... having had significant compensation in the past for their brilliant judgments ... which now has been shown to be significantly flawed ... now there is some amount of decision paralysis ... having made so many thoroughly bad loans, they may be quite gun shy going forward, making new loan decisions; over adjustment for significant amount of past mistakes. recent decision paralysis post:

I just noticed this thread today. I see there is a lot of speculation and incorrect statements, so let me try to clarify.

First, from a processor implementation point of view, there is no problem with the old-style MVCL/CLCL interruptible instructions. At appropriate points based on pending interrupts and potential page crossings leading to an access exception, the millicode exits from their execution and sets the GRs and PSW appropriately to continue later. There is no risk of checkstops and it is perfectly well architected to handle a page fault in the middle, as some have speculated.

The reason for the new CC3-style interruptible instructions is very simple. It was requested by software developers (both internal and external to IBM). It allows more flexibility in handling other system activity that is not interrupt driven. So for example, software can go off and perform some housekeeping while a long running MVCLE is executing. Note that POPS requires the processor to exit with a CC3 every (approximately) 4KB processed. So for a multi-page move, the overhead of starting and stopping can actually slow down the throughput of the move very slightly.

I would expect that all future interruptible ops be of the CC3-style. That said, there will be at least one new interruptible version of an existing instruction announced soon, however, it is an instruction never used by the vast majority of software developers.


re:
https://www.garlic.com/~lynn/2008c.html#67 What happened to resumable instructions?

long storage-to-storage operations with lots of accesses back to real storage ... is costing ever increasing number of processor cycles (as mismatch between processor speed and memory speed increases) ... recent reference
https://www.garlic.com/~lynn/2008c.html#92 CPU time differences for the same job

one could claim that nearly the same effective results (cc3-style) could be achieved for old-style interruptable instructions under program control ... but requiring a few more registers for loop control ... i.e. actual length is kept in other registers and the lengths used for mvcl/clcl instructions being limited (to 4096).

there are other thruput issues associated with long storage-to-storage operations; even back to working on original mainframe tcp/ip product implementation.

at the time, some of the competitive tcp/ip implementations were looking at 5k pathlength and five buffer copies ... and there was comparison with something like 150k instruction pathlength and 16 buffer copies for lu6.2. at that time, assuming 8kbyte NFS size buffer ... the processor overhead for the 16 (LU6.2) 8kbyte storage-to-storage buffer copy operations exceeded the processor time for the rest of the pathlength.

the other factor that some processors provided was cache-bypass, storage-to-storage instructions. Large number of significant sized storage-to-storage operations ... not only has ever increasing significant overhead in terms of processor cycles ... but can have an extremely detrimental effect on cache occupancy (the actual data in most of the buffers has little probability of ever being needed in the cache, but replacing data that would be needed).

Spammers' bot cracks Microsoft's CAPTCHA; Bot beats Windows Live Mail's registration test 30% to 35% of the time, says Websense
http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9061558

from above:
The bot, said Hubbard, grabs the CAPTCHA -- which is not plain text but actually an image -- and sends it back to the spammer's server, where the image is somehow "read" and a clear text match is generated. The text is then sent back to Live Mail, where it's plugged into the box where users normally type the CAPTCHA characters.

Consumers Favor PINs Over Banks' Debit Payment Needles; Contact-less and signature-based authorizations are not preferred because consumers believe the methods favored by banks are less secure, a Gartner survey found.
http://www.informationweek.com/consumers-favor-pins-over-banks-debit-payments/d/d-id/1064365

from above:
According to a survey of 4,500 online U.S. adults, the marketing push has failed to steer most consumers away from the use of PINs, Gartner said. Consumers refuse to change because they believe the methods favored by banks are less secure.

Consumers prefer entering a PIN when using a debit card over all types of signature-based card payments, whether credit or debit, Gartner found. Banks promote signature-based debit payments because they earn more fee revenue from card-accepting merchants.

Banks charge more on the premise that signature-based payments are riskier and more prone to theft.


... snip ...

one of the issues discussed in this thread is certain kind of vulnerabilities with debit transactions when signature debit was introduced ... even when it might involve a card that had never been used.

another debit card vulnerability that crops up with signature debit ... can involve debit cards that are enabled for both signature debit and pin-debit. even if the card is only used in pin-debit mode ... it would still be possible for a crook to skim the magstripe, create a counterfeit card ... and use the card in signature debit mode .... w/o ever knowing the pin.

this is somewhat analogous to part of the x9.59 standard
https://www.garlic.com/~lynn/x959.html#x959

referenced in this post
https://www.garlic.com/~lynn/2008c.html#89 Toyota Sales for 2007 May Surpass GM

about account numbers used for x9.59 transaction can not be used in any other kinds of transactions.

it usually involves special request now, but it is possible to obtain a debit card that can only be used in pin-debit mode.

note that past studies have found signature debit has 15 times the fraud of pin debit ... misc. past references:
https://www.garlic.com/~lynn/2006e.html#21 Debit Cards HACKED now

https://www.garlic.com/~lynn/2007k.html#12 IBM Unionization

... for other topic drift ... in the same time frame as the x9a10 financial standard working group effort on the x9.59 financial standard for retail payments ... there were a number of other efforts that attempted to come up with specifications for small pieces of the overall problems.

some of the other work was doing internet specific specification, but wasn't applicable to point-of-sale and involved enormous payload and processing bloat
https://www.garlic.com/~lynn/subpubkey.html#bloat

other work in the period was for chipcards that could only be used at point-of-sale ... but specification wasn't usable for internet (card-not-present, cardholder-not-present, MOTO) transactions ... and had other deficiencies
https://www.garlic.com/~lynn/subintegrity.html#yescard

a problem with using PIN-debit in internet environment is that the PIN is a shared-secret ... and is to be kept confidential and never divulged (which is difficult to achieve in an internet environment)
https://www.garlic.com/~lynn/subintegrity.html#secrets

there were various attempts in the early part of this decade to introduce various debit-based products for the internet environment (even some that had specification very similar to x9.59 protocol). however, there was large disconnect between the merchants and the financial institutions which has never been resolved. As per the referenced article, the merchants have gotten use to the justification that (significantly higher) interchange fees are proportional to products' vulnerability to fraud. For a product that eliminated nearly all of the existing fraud ... it follows that there would be much lower interchange fees. The counter offer was that since such products eliminated nearly all the fraud, the interchange fees should carry a premium over and above the products that were vulnerable to lots of fraud.

the x9a10 financial standard working group there was work on making the resulting (x9.59) standard (light weight and) applicable to all possible environments (including being able to meet iso 14443 contactless power profile within transit gate timing constraints) ... w/o sacrificing any security.

from above:
The loss of a CD by HM Revenue & Customs in November 2007 containing personal and financial details of over 7 million families claiming child benefit was swiftly followed by assurances that such a mistake would never happen again. Then in February, an agency of the Department for Health* admitted that over 4,000 NHS smartcards (UK cards providing access to an individual's health records), giving potential computer access to patient records, had been lost or stolen - and nearly a third of these in the last year alone.

https://www.garlic.com/~lynn/x959.html#x959

didn't do anything about trying to protect the information ... however, it did include countermeasure making the information useless by crooks for fraudulent transactions.

it is similar ... but different to the idea behind one-time account nubmers ... recent post

insider problems can be divided into two scenarios.

1) systems that are vulnerable because they have dual-use secret based operation. the secret ... like an account number ... is required for both authentication ... aka something you know authentication, from 3-factor authentication paradigm
https://www.garlic.com/~lynn/subintegrity.html#3factor
... and also for standard business process. all sorts of processes are put in place to keep the secret information confidential and never divulged ... but at the same time, the dual-use nature requires that it has to be exposed to large number of individuals (ala insiders) performing their duties. the core systemic flaw is the dual-use characteristic, insiders still can harvest the information and leak it for "imposter" attacks. one approach (ala x9.59 financial standard) is to eliminate the dual-use vulnerability of the information.

2) insiders just performing their day to day operations. countermeasures are multi-party operations, partitioned duties and authority. attacks on these systems involve either an insider exceeding their authority by impersonating other individuals (in the multi-party operatons), collusion where multiple parties are involved, and/or lax controls enforcing the multi-party operations.

first kind of insider scenario could be copying master account database and making it available for others to perform fraudulent transactions, impersonating the individual account owners. this frequently gets lumped into the identity theft/fraud category

the second kind of insider scenario are things like embezzlement ... where the individual "exceeds" their authority to transfer organization funds to an outside account. more complex might be loans to ficticious individuals and/or based on non-existent collaterial. One of the loan fraud scenarios from the 80s (as well as other eras) was large mortgages on buildings at addresses that turned out to be empty lots and/or mortgages to individuals that have possibly no possible way of repaying them (and the money otherwise disappears). Countermeasures supposedly were controls requiring independent appraisals and audits. When online satellite photos systems were introduced ... there were suggestions that at least there could be controls that independently verified whether there was actually a building at the address (some of the more blantent mortgage fraud scenarios from the 80s). However, the mortgage fraud scenario can also simply be theft by outsiders, although they may be aided and abetted by incompetent "insiders" and lax processes (evolution of controls tend to try and compensate for both incompetent as well as crooked insiders)

The identity theft/fraud scenarios are more likely to show up in the popular press ... especially after the introduction of breach notification laws. The natural tendency for many of the institutions has been to sweep such incidents under the rug. Part of the issue is many of the involved institutions ... their basic "currency" is trust ... and publicity of such events tends to tarnish and devalue that "currency" (sometimes more so than the events themselves).

sometimes that is incompetent insiders ... as per previous ... and some of it is plain/normal human mistakes.

to wander back into computers and dataprocessing ... i've mentioned before we were spending some time talking with a major financial network a few years ago. they had attributed nearly a decade of 100percent availability to

ims hot-standby involved triple replicated systems in two geographic locations. this provided high availability for system failures as well as various kinds of natural disasters.

however as referenced in the past ... starting sometime in the early 80s, hardware problems stopped being the major cause of failures. as other kinds of failures were addressed ... human mistakes started becoming one of the (few) remaining sources of failures. automated operator eliminated most of the (remaining) human mistakes as a source of failures that they had previously experienced.

mainframe IMS used to dominate backend financial systems ... and is still found in large number of core backend systems (even with the apparent ascendancy of rdbms in more popular mind ... but ims continues to be a main component of major industrial dataprocessing).

for random drift ... old email reference to when jim was leaving for tandem ... and palming off on me, consulting with the IMS group ... and interfacing to outside organizations on relational (including large financial institution looking at relational)
https://www.garlic.com/~lynn/2007.html#email801006
https://www.garlic.com/~lynn/2007.html#email801016
in this post
https://www.garlic.com/~lynn/2007.html#1 The Elements of Programming Style

there was funny situation about a particular large financial institution. one of the people from the IMS organization (in STL) had gone there to head up dataprocessing. he was out hiring IMS development programmers and the "joke" was that he had managed to put together a larger IMS development team ... than the "official" IMS development group in STL. that financial institution (or at least one with the same name) continues to have very large amount of core financial dataprocessing systems using IMS.

for other drift ... i've mentioned before my wife being con'ed into going to pok to be in charge of loosely-coupled architecture (i.e. mainframe for cluster) ... where she developed peer-coupled shared data architecture
https://www.garlic.com/~lynn/submain.html#shareddata

... she left the position after short stint, because (except the IMS group for IMS hot-standby) there was very little uptake until much more recent with (mainframe) sysplex.

it might be that in a xen or a vmware n.g. .... related to current implementations ... there might be more of the attitude that there isn't anything to learn about what was done in 1968 ... but it seems odd to make that assertion that something from 1968 isn't "entirely on-point" in a computer folklore n.g.???

there has been some relatively recent threads in mainframe newsgroup about the difficulty that i/o subsystems present for virtualization ... which is along the lines of similar articles regarding the difficulty that i/o subsystems (in some of the PC-based platforms) present for virtualization (on those platforms). the difficulty of i/o subsystem virtualization dates back to at least the early efforts in the mid-60s.

actually software back then was free (and source readily available) and lots of univ. and other organizations actively worked on the software. it was mostly gov. litigation that led to the "unbundling" announcement on 23jun69 (starting to charge for software) ... misc. past posts mentioning unbundling
https://www.garlic.com/~lynn/submain.html#unbundle

however, the corporation was able to make the case with the gov. that kernel software still should be free ... which pretty much continued for nearly another decade ... before the pressure & transition to charge for all (including kernel) software.

a lot of the work came out of the corporations science center on the 4th flr of 545 tech sq:
https://www.garlic.com/~lynn/subtopic.html#545tech

and was somewhat a small, lean operation. it was only about 30-40 people at the time ... and was responsible for creating all the virtual machine stuff, as well as lots of timesharing work
https://www.garlic.com/~lynn/submain.html#timeshare

and other interactive, online technology. It was also responsible for the technology that was the basis of the internal network (the internal network was larger than the arpanet/internet from just about the beginning until possibly summer 85)
https://www.garlic.com/~lynn/subnetwork.html#internalnet

and also univ. bitnet/earn network
https://www.garlic.com/~lynn/subnetwork.html#bitnet

it was also where gml was invented in 1969 ... precursor to sgml, html, xml, etc
https://www.garlic.com/~lynn/submain.html#sgml

there were some number of commercial timesharing service bureaus startups that spun out of the science center and/or were cp67 and/or vm370 based ... recent reference in D&B and NCSS thread:

The cloning experiment was not, from Apple's point of view, working; on the contrary, it meant increased expense (developing reference motherboards) and reduced income (customers choosing clones rather than Apple machines).

lots of cloning scenarios down thru the ages have relied on fundamental (viable) eco-system and then leverage it into additional niches.

sometimes there can be mutual parasitic relationship between the clones and the large infrastructure. lots of clones dramatically increased the market size. the increase in market size justified spending on fabs that run to billions of dollars each ... in order to get further economies of scale. in some cases the fab costs are justified for specific chip ... but the same fab/process can also be leveraged for other chips (relying on economies of scale of large operation to succeed in their nich markets).

the internet growth is somewhat similar ... combination of massive scale of personal computers and massive telecommunication infrastructure (also requiring billions of dollars in investment).

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

quote from the above (i.e. response to clone controllers):
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 ...

in addition to stuff done as undergraduate in the later half of the 60s on various system and software stuff (including a lot of work on virtual machine system) ... i had also gotten involved with a project at the university on creating a (mainframe) clone controller.
https://www.garlic.com/~lynn/submain.html#360pcm

this got written up later as four of us being responsible for some amount of the clone market.

later with the appearance of clone processors, the focus on the future system effort ... and letting the 370 product pipeline dry up ... contributed to letting the clone processors get a foothold in the market place.

the success of the clone processors contributed to the decision to start charging for kernel software. the gov. litigation was big motivation behind the 23jun69 "unbundling" announcement
https://www.garlic.com/~lynn/submain.html#unbundle

and starting to charge for application software. however, the corporation was manage to make the case that kernel software should still be free ... which lasted for nearly another decade.

i got to have some discussions like this with some of the mac developers (before initial mac announcement). my brother was regional marketing rep for apple (claimed to have the largest physical region in conus). he would periodically come to town and we'd go out to dinner ... with other people from apple (including some mac developers).

my assertion was that a significant contributing factor to achieving market size and breaking out of the computer hobbyiests market segment was terminal emulation. business could buy a pc for about the same price as 3270 terminal and in single desktop footprint ... get both existing terminal operation and some local computing capability. individual businesses might have tens of thousands of such terminals ... so it was enormous market ... ready-made to be taken over by PCs. It was relatively no-brainer business decision, money would have already been budgeted for the terminals ... so no really new financial case and/or major justification was required for the purchases.

once some market size threashold had been past ... it started attracting large number of application developers and the clone makers ... creating snowball effect ... increasing number of new applications, increased the perceived value ... while at the same time, the clone makers were driving down the price ... which fueled increased purchases.

from above:
A survey of 705 U.S.-based IT decision-makers at mid-sized to large enterprises found the most established alternative to thick-client systems, Terminal Services (a.k.a. thin client computing), scored highest in awareness of the compute model (96 per cent); familiarity with the technology (84 per cent); deployment in any capacity, including test installations (64 per cent); and high-volume production installations (31 per cent).

for businesses, thin client (current flavor of terminal emulation) addresses a lot of the compromises and vulnerabilities of PCs ... especially connected to internet with employees loading up all sorts of unimaginable stuff.

later there were issues about whether automobiles should have countermeasures for common accident results ... things like bumpers, safety glass, padded dash boards, seat belts, impact zones, brake lights, turn signals, etc. along the way, there was also stuff about the need for traffic rules, right of way, traffic lights, crosswalks, etc.

in many respects computers are still undergoing the transitional period from professional use ... to general public appliance.

there is still a lot of automobile use by people that have no business using them. random past reference:

Euroclear establishes third back-up data centre
http://www.finextra.com/fullpr.asp?id=19855

from above:
The Euroclear group's two primary data centres, located outside metropolitan areas, use real-time data replication and load-balancing features to ensure full synchronisation of data and transaction-processing capabilities between the two facilities. This allows either of the two primary data centres to take over technical operations within one hour of a local disaster affecting the other centre. Production data is also streamed asynchronously to the newly opened third data centre, located hundreds of kilometres away from the primary sites. The third data centre is designed to take over the group's (including Euroclear UK & Ireland targeted for 2010) critical transaction-processing and data-storage operations within three hours of a regional or metropolitan disaster that renders both primary data centres out of action. In extreme cases, a period of reconciliation may be required before full processing resumes using the third data centre.

although the above states "IBM research" filed importantant patents like the first for RAID in 1978.

however

references wiki page
https://en.wikipedia.org/wiki/Redundant_array_of_independent_disk
https://en.wikipedia.org/wiki/RAID

and patent 4,092,732 awarded in 1978. The inventor was in the disk division, not in the research division.

Some folklore regarding driving factor behind shipping first raid implementation was that the filesystem infrastructure treated all available disks as common subpool resulting in pieces of files scatter allocated across all available devices. Single failures affected complete system and could require restore of complete system across all devices.

Javascript disabled in Firefox

Interesting observation about Firefox users - folks a bit more knowledgeable. Also interesting is that the risks of using IE are borne by the end user, not the company. Perhaps we need to give these companies some incentives to support Firefox to counter the pressure from MS.

before firefox, i was using mozilla with tab support ... i had folder that i could click on and fetch 100 or so different websites in different tabs (while i went out for coffee) ... this was somewhat to compensate for having a dial line ... and objected to the latency with standard web browsing.

the initial folder had lots of news sites ... and interesting links, I would click for loading asynchronous in the background (into yet another new tab). by the time, i had finished the first 100 tabs ... i might have yet another 400-800 (or sometimes more) to look at. all of these default to javascript off.

at the time, mozilla would start to noticeably bog down with more than 300-400 open tabs. Enabling javascript execution would really aggravate the situation ... to the point that mozilla would frequently hang saying that some script was not responding (and required clicking on a popup).

firefox appeared and pushed as significantly more lightweight ... so i switched (but still kept javascript disabled).

along the way, i found that it was possible to signal firefox externally for loading URL into new tab. I moved the initial folder URLs to an external process that used WGET to retrieve the initial URLs, and (having saved the previous retrieval) check for new URLs on the pages. Then the external process would remove any duplicates and cross-check "new" URLs against the browser history information ... before signalling firefox to load each URL into new tab (sort of analogous to very targeted search engine process ... with background asynchronously fetching of "new" web pages into new tabs).

recent post describing some of the process
https://www.garlic.com/~lynn/2008b.html#32 Tap and faucet and spellcheckers
https://www.garlic.com/~lynn/2008b.html#35 Tap and faucet and spellcheckers

firefox has since moved its history (and other) information into relational respository ... so looking at the history information requires some sql queries.

You know, I never liked the term "roles". It's a "hot" term in the theoretical world, but I guess I never see a practical use of it when we get down to actually assigning rights to people. To me the easier concept is ACL - that's something that just naturally fits into the sort of access control decisions we want to make. The examples I've seen where they show "role" assignment always seem contrived, and somehow we never end up doing things like that.

part of NIST/RBAC from a decade ago was to provide some support for separation of duties. this is somewhat trying to get back to (at least) the early 80s when multiple party operations was being used as countermeasure to insider fraud. the internet somewhat distracted attention from insider fraud ... even tho during the period, it has continued to be as much as 70percent of the problem.

fine-grain permissions would be separated into roles with a view to supporting separation of duties ... as part of multi-party operations as countermeasure to insider fraud.

the problem in the real word ... was that the separation of permissions might not completely account for real business processes. Since some amount of the institutional knowledge may have evaporated with regard to all the work that went into exactly which permissions needed to maintain separated ... and the sometimes mismatch between the aggregate defined roles not matching real-world roles ... the same individual might be assigned multiple roles ... undermining the objective of mandating multi-party operations and separation of permissions (as insider fraud countermeasure).

because of the typical roll-up of permissions into roles and the way the related hierarchical information was being maintained ... it frequently was not possible to easily evaluate consequences of assigning the same individual multiple roles ... aka would the aggregate set of permissions violate multi-party mandates and negate the insider fraud countermeasures ... or exactly what are all the possible combinations of fine grain permissions that will create insider fraud opportunities (and undermine separation of duties)

part of the issue getting back to the early 80s state-of-the-art is maintaining the separation of duties and permissions and then having to deal with multi-party collusion as a vulnerability ... and then working on developing collusion countermeasures.

some of it is a lot of systems with split between real-time/frontend authorization and settlement in (mostly) overnight batch windows ... it starts to become more of a problem if there are successful conversions to straight-through processing ... putting more and more stress on real-time availability.

a little topic drift mentioning "stand-in":
https://www.garlic.com/~lynn/aadsm28.htm#17 Lack of fraud reporting paths considered harmful
https://www.garlic.com/~lynn/aadsm28.htm#18 Lack of fraud reporting paths considered harmful

the above was reference to institution doing upfront fraud analysis and denying transactions ... and looking for processing message type (indicating the denial) that would make it back to their acquiring processor and all the way back to the issuing processor (as a way of automatically indicating to the issuer possible fraudulent transactions against the account).

that discusses real-time authorization (which includes possibility of "stand-in") and batch settlement processes ... that frequently occur in overnight batch window.

previous posting mentioning zNextGen program:
https://www.garlic.com/~lynn/2008c.html#45 Young mainframers' group gaims momentum

can you say HONE? (Hands-On Network Environment) ... misc. past posts
https://www.garlic.com/~lynn/subtopic.html#hone

before the 23jun69 unbundling announcements ... novice system engineers would get hands-on experience in customer accounts ... as part of larger team of SEs (with a variety of experience) ... sort of apprentice type program.

after the 23jun69 unbundling announcements ... besides starting to charge for software ... SEs time at customer accounts were also charged for. The situation at the time couldn't come up with having apparentice SEs learning on the customer nickle.
https://www.garlic.com/~lynn/submain.html#unbundle

the initial solution was to put in some number of cp67 virtual machine systems ... and provide remote login access to SEs from branch offices.

the science center had pioneered virtual machines systems in the mid-60s ... starting with cp40 (on specially modified 360/40 supporting virtual memory) which morphed into cp67 (when standard 360/67 machines with standard virtual memory support become available)
https://www.garlic.com/~lynn/subtopic.html#545tech

the science center had also ported apl\360 to cms\apl. apl\360 installations had typically been limited to 16kbyte or 32kbyte workspaces. the cms\apl port opened up workspace size to full virtual memory (although parts of apl had to be reworked for virtual memory operation).

The dramatically increased workspace size and some other features (added to cms\apl) ... allowed a lot more real-world applications to be done in apl. One instance was that corporate hdqtrs people loaded the most sensitive coporate information on to the cambridge system and ran remote business modeling applications from armonk. This required a very high level of security since the cambridge system also had various non-employees from the area universities and colleges using the same system.

a little topic drift regarding the security issue:
https://web.archive.org/web/20090117083033/http://www.nsa.gov/research/selinux/list-archive/0409/8362.shtml

another use of cms\apl was to deploy sales and marketing applications on the HONE systems, supporting branch office (other than SEs). Eventually these sales and marketing applications came to dominate all HONE activity ... to the exclusion of SE "hands-on" use. Before long, it was not even possible for customer machine orders to be submitted unless they had been preprocessed by some HONE application.

for slightly other topic drift:
https://www.garlic.com/~lynn/2008d.html#17 more on (the new 40+ yr old) virtualization
https://www.garlic.com/~lynn/2008d.html#23 more on (the new 40+ yr old) virtualization

for other folklore topic drift ... starting in the late 70s, there was constant series of efforts to move HONE (sales & marketing apl applications) off of vm370 and on to MVS. The cycle was approx. two years, a new executive would come in, discover to their horror that the corporation didn't actually run on MVS ... and mandate HONE be moved to a MVS platform. All work would stop for 6-9 months while everybody worked on attempting to move things over ... which would eventually fail miserably ... and then things would be back to almost normal for a short period until the next executive replacement. At one point in one of cycles in the early 80s, one of the POK executives admonished the HONE organization that a MVS port would easily be possible if they would just rewrite all the APL applications in assembler.

How much time was spent doing garbage collection in the APL workspace given all of arrays that would get created as intermediate results in a single statement? I could imagine that garbage collection might be even be required one or more times during the execution of a single statement in a function. A description of how APL managed storage in workspaces might make interesting reading.

re:
https://www.garlic.com/~lynn/2008d.html#32 Interesting Mainframe Article: 5 Myths Exposed

on assignment, apl would always allocate a new storage location ... until it exhausted storage and then perform garbage collection and compact all variables. storage utilization was based on number of assignments ... somewhat independent of amount of in-use variables. this was developed for 16k real workspace that was swapped in&out (as single unit)

this was initially quite tramatic moving to large virtual memory, paged environment (apl application guaranteed to repeatedly touch all available virtual memory)

one of the was things developed at the science center
https://www.garlic.com/~lynn/subtopic.html#545tech

(used to look at performance and execution characteristics) was the precursor to vs/repack (release as product by the science center in the mid-70s) ... basically instruction address and data store&fetch addresses. initial version would create plots out on 1403 ... used was greenbar fanfold paper loaded backwards ... so printing was on whiteside. standard setup was to print every storage references ... storage addresses scaled to about 6' of printed output (vertical) and equivalent to 2000 instructions for every print position (horizontal) ... i.e. equivalent of 264,000 instructions acrossed a page. These printouts were taped to the walls of science center hall ... so instruction execution progressed as you walked down the hall ... showing storage & instruction location use from low storage (near the floor) to high storage (near the ceiling).

initial apl storage use had very sharp sawtooth pattern ... references progressing quickly from low storage (near the floor) to high storage (near the ceiling) ... and then sharp vertical line when garbage collection was performed. apl would quickly & repeatedly touch every available page in virtual memory ... regardless of actual program size. so one of the things that was done before cms\apl shipped (originally on cp67/cms) as a product was to redo garbage collection so that its storage use was much more virtual memory and paging friendly.

later palo alto science center did significant apl enhancements ... as well as implementing the 370/145 apl microcode assist ... which was released as apl/cms (on vm370/cms).

recent posts mentioning vs/repack ... which would do program execution and storage utilization analysis and perform semi-automatic program reorganization (for optimizing real storage use in virtual memory environment)

from above:
A new report has labeled Knowledge Process Outsourcing (KPO) as a recognized and mainstream outsourcing option, particularly in the financial services sector.
...
To better explain KPO, Hayward cites the hypothetical example of a Wall St equities research firm which is faced with spending $250,000 to cover a specific stock when the most it can hope to achieve in revenues from that research is $200,000.

However, if that research can be outsourced to a KPO provider at a cost of $100,000, the operation suddenly returns to profitability

however, it may also be explained by increase in demand for knowledge workers ... and decline in number/quality of new college graduates.

it is all relative ... and/or return-on-investment

aka whether overall lower net costs of COTS w/modifications or a wholly developed RYO (roll-your-own) implementation.

also there are business opportunity costs ... aka whether the business can better spend the same amount of money someplace else (ROI).

for extreme scenario ... a large datacenter (billion or two in mainframe hardware) paid all the engineering and development for a new, significantly better PDU (power distribution unit) ... and then turned it over to a PDU vendor. the business easily justified having a much better PDU ... but couldn't justify actually getting into the PDU business. That PDU is now a staple in large number datacenters.

another such example was a large financial institution hired several experts in complex pattern algorithms and created a sophisticated new fraud detection tool ... and then turned it over to a vendor of fraud detection applications. Again, the business easily justified having much better fraud detection ... but didn't actually justify ongoing development and support ... any competitive business advantage was more than offset by having ongoing support&development amortized across a large number of customers (and because of competitive business issues they wouldn't have been able to easily directly vend the product to other institutions)

from long ago and far away, the following was posted yesterday to the z/VM mailing list .... it refers to somebody trying to track down old contributions to the vm share "waterloo" tapes. This period was just the leading edge before starting to charge for system software and several years before the OCO-wars (i.e. object-code-only, stop shipping full source code and shipping source code maintenance)

x-over from z/VM mailing list:
Does anyone have a copy of the old Waterloo tapes "CIA Mods" tape referen= ced in this entry in the ABSTRACT ABSTRACT of the Waterloo tape for VM/370

M1086V00CIA MODS-- Our local mods that have been contributed to the Waterloo VM Library now consume more than a reel of tape. Since our local facilities tend to be of interest to a relatively small number of installations, we will merely place a notice of availability for mods that have been updated to the current level of VM/370. RELEASE6 MEMO describes our contributions and current level of VM/370. They include: 1) Batch Monitor Facility - A disconnected virtual machine that monitors and controls jobs submitted for processing on remote batch systems. Formerly M0081V00 on Release 5. 2) PROC Structure Macros and Library - The PROC system is a set of several hundred assembly language macros that perform a variety of functions, including subroutine linkage and storage allocation. Formerly M1112V00 on Release 5. 3) SEDIT - An editor that is more powerful than EDIT yet less than XEDIT. Formerly M1113V00 on Release 5. 4) TAPEMON - A disconnected service virtual machine that processes user requests for tape drives and volumes. 5) CLASSIFY - A printed output classification facility that allows users to specify protective markings to be 'rubber stamped' at the top and bottom of spool files directed to the real printer. This mod is M1085V00 on this Release 6 Library.--David Farnham, Central Intelligence Agency, ODP/SPD, Washington, D.C. 20505, (703) 351-6078, August 27, 1980.

and some related old email
https://www.garlic.com/~lynn/lhwemail.html#nsfnet

we had been working with univ and nsf ... starting before the mid-80s about being able to have T1 being deployed ... rather than the 56kbit that was commingly being deployed ... since we had done an operational backbone internally ... misc. past posts mentioning internal network that was larger than arpanet/internet from just about the beginning to sometime summer of '85. Part of the reason that the internal net was so much larger than the arpanet ... was the incremental costs for link on the internal network was orders of magnitude smaller than the incremental cost for arpanet link:
https://www.garlic.com/~lynn/subnetwork.html#internalnet

our backbone was T1 (and higher speeds) that we had done out of a project that i had named HSDT (high-speed data transport)
https://www.garlic.com/~lynn/subnetwork.html#hsdt

somewhere along the way, we were not allowed to continue in the effort and univ/nsf meetings that we had already scheduled were being canceled ... some of this is detailed in the old email references. Attempting to help us, the director of NSF had an audit of what we already had running ... that concluded that it was at least five years ahead of all NSFNET bid submissions (to build something new) ... and wrote a letter (to the effect) copying the ceo ... which actually aggravated the internal corporate politics. however, we do believe that we contributed significantly that the NSFNET-1 RFP called for T1 links.

As it happened, the winning bid wasn't able to deploy T1 links ... they were only 440kbits; however, possibly to meet the letter of the contract, the did install T1 trunks with telco multiplexing equipment to run multiple 440kbits links over the T1 trunks.

As it turned out ... this was in a period that the telcos and others had significant amounts of extra transmission capacity (lot of it in the form of dark fiber). They were faced with a significant chicken and egg situation ... they had pretty high fixed run rate that was in large part covered by transmission charges. They needed new bandwidth hungry applications to utilize all the bandwidth ... however it wasn't very likely that these applications would appear without dropping trasmission charges by order of magnitude. If they did that, it would take several yrs for the new applications to appear and catch on ... during a period where the transmission-based charging paradigm wouldn't be able to cover their fixed infrastructure run rate.

the mechanism was to significantly enhance the resources availble to the NSFNET backbone. conservative estimate was that these resources were 4-5 times what gov. actually paid for in the contract. however, along the way, it was in the interests of the commercial operations (contributing the resources) ... to not allow them to be used for commercial purposes (i.e. not siphon off commercial revenue) ... have them purely dedicated for the incubator purpose, encouraging the evoluation of a whole generation of new bandwidth hungry applications.

on the other hand ... there was separate "csnet" with 56kbits links leading up to nsfnet ... old email references
https://www.garlic.com/~lynn/98.html#email821022
in this post:
https://www.garlic.com/~lynn/98.html#59

and in that same time, there was bitnet ... which was a separate educational network using "mainframes" (effectively the same technology used in the internal network). however a lot of these mainframes were large numbers of 43xx machines (sold into the same market segment as vax machines ... although there were more 43xx machines sold than vax machines)
https://www.garlic.com/~lynn/subnetwork.html#bitnet

and a little later, EARN was being formed in europe ... using the same bitnet technology ... and earn/bitnet was interconnected. old email from person charged with putting together earn ... and asking if i could help
https://www.garlic.com/~lynn/2001h.html#email840320

https://www.garlic.com/~lynn/2001h.html#65

both BITNET and EARN were largely a corporate funded operations ... not government. as in the case of the internal network ... most of the network connected machines were running the virtual machine operating system.

lots of universities offered online accounts to these virtual machine systems ... so there were large number of people with access to virtual machine facilities ... and it was possible to run other operating systems in these virtual machines ... including another copy of the virtual machine operating system.

this is alluded to for internal sales support technical employees in this recent post regarding 23jun69 unbundling announcement (i.e. starting to charge for software) and creation of the HONE "system":
https://www.garlic.com/~lynn/2008d.html#32 Interesting Mainframe Article: 5 Myths Exposed

the above makes reference to corporate program offering additional virtual machine mainframe resources to students. also reference in this previous post

participants were universities and students. some of this can be seen in the vmshare postings ... an online conference system provided by tymshare to the SHARE organization starting in aug76 ... on their vm370 based commercial timesharing system ... the archive can be accessed here:

there were fanctions in the gov. starting around 1980 (including guy who coined the term) starting to push COTS ... i.e. being able to amortize (frequently technology) costs over a much larger commercial base. The issue was where to target funding to aid things along a little bit and/or provide an incubator environment ... on the way to COTS. NSFNET backbone was (pretty much) plain service agreement ... although encouraging the evoluation of T1 and faster speed usage .... although the HSDT project somewhat got shanghied along the way and not allowed to directly participate, install and/or run the operation ....

somewhat as seen in this old email reference
https://www.garlic.com/~lynn/2006w.html#email870109

some of the factions responsible for blocking our nsfnet participation were also pontificating inside the corporation that corporate proprietary communication implementations could be used for nsf.

there was big upswing of vax & 43xx class machines in the early 80s ... especially in educational institutions ... providing increased computers exposure.

old post giving detailed vax sales, sliced & diced, by year, model, us, non-us, etc:
https://www.garlic.com/~lynn/2002f.html#0 Computers in Science Fiction

43xx machines saw similar uptake. the big difference is that there were large institutions placing orders for multiple hundreds of 43xx machines (which wasn't really seen in the vax sales) ... and as a result ... totally number of machines shipped was greater. This old email refers to customer with a large mainframe installation (from a different vendor) starting to look at 4341 machines ... initially 20 such machines (each approx. as powerful as their old "glasshouse" mainframe) ... the order quickly become 210 machines (instead of 20)

other old email on various subjects related to 43xx machines and their starting to change perception of computing
https://www.garlic.com/~lynn/lhwemail.html#43xx

this contributed to conference room crisis in the early 80s for some organizations. they were getting so many of these machines for departmental usage ... and having them installed out in the individual departments ... frequently in a room that previously had been designated a conference room.

(Very simplistic, M0 is the physical cash, M1 also includes mature cheques and similar bills, M2 includes everything you can issue a debit card on, and M3 includes everything in bank, broker and credit card accounts; account credits included. The latter figure is usually close to 100 times the first (zeroth?) one.)

and now for something different, decoupled debit card:

Decoupled Relationships: The Evolution of Debit
http://www.americanbanker.com/usb_article.html?id=2008012594PXFM5M

from above:
Here's how it works: An intermediate service provider, such as Capital One, issues a consumer a new "debit" card. When the consumer makes a purchase, the transaction is performed and settled between the merchant and the intermediary online, over the branded payment networks. Then, the funds are then deducted from the consumer's checking account and paid to the intermediary using the offline ACH network. The "decoupling" of the debit transaction from the bank at which the consumer maintains a checking account allows the intermediate service provider to capture the interchange income from the card transactions which would normally go to the bank that holds the checking account, Mercator says. That allows the consumer to capture points he might not otherwise.

... snip ...

in effect the processing is little different than needed for a gift/stored-value card ... but the consumer registers their ach routing code for the card. the processor for the card then takes the incoming transactions and eventually schedules it for the ACH network. i would guess that anybody that has processing setup for doing gift/stored-value cards ... could add the additional processing and be able to execute the ACH transaction (and the card they issue to do both debits and as well as credits via ACH transactions) ... just need the ability to register the consumer's bank (ACH) routing code.

Prior to the 3031, did those "standalone" channel boxes (e.g., 2860, 2870, 2880) use execution units similar to the 360 processors, or were they designed from the ground up to be a channel?

re:
https://www.garlic.com/~lynn/2008d.html#39 Throwaway cores

the 360 processors didn't (necessarily) use execution units that were in any way to similar to 360 instructions.

the execution unit in the 370/158 was horizontal microcode engine ... it had one set of (horizontal) microcode for the integrated channel program and another set of (horizontal) microcode that implemented 370 instructions.

the native microcode engines that were used didn't have a lot of relationship to each other or to 360.

the low-end and mid-range machines tended to be vertical microcode machines ... the high end tended to be horizontal microcode engines.

the corporation eventually had a very large variety of different microprocessor.

a semi-close scenario would be project i got involved with as undergraduate ... i was trying to get the standard corporate telecommunication controller to do something that it couldn't do. somewhat as a result, the university had a project to build a clone controller ... but using an interdata/3 ... which had a somewhat 360 instruction set. the channel interface was reverse engineered and a channel interface board was built for the interdata/3, and interdata/3 software was implemented to emulate the standard mainframe communication controller ... interfacing to channel. this got written up blaming us for some amount of the mainframe clone controller business
https://www.garlic.com/~lynn/submain.html#360pcm

the implementation evolved into a cluster of interdata/4 and interdata/3s .... with the interdata/4 managing the channel interface, and the interdata/3s dedicated to linescanner functions.

for other drift, later generation of interdata (decade later) was one of the first (non-pdp) unix ports.

another example was 3830 disk controller ... which was also a (high performance) horizontal microcode processor. there was a decision to implement the 3880 (3830 follow-on) using (jib-prime) vertical microcode processor. part of the issue was that there was going to be significant more function put into the 3880 controller ... and programming state-of-the-art for vertical microcode was significantly better than for vertical microcode. the jib-prime was significantly slower than the processor used in the 3830 ... even tho there was requirement for 3880 to handle twice the max. transfer rate (3mbytes vis-a-vis 1.5mbytes). The implementation compromise involved custom hardware data paths for transfers ... so that the jib-prime only needed to handle control function (a lot less effort). Even with data transfer offloaded to custom circuits ... the jib-prime (in the 3880) handled many functions signficantly slower than the 3830 horizontal microcode engine.

around 1980, there was big push to replace the large variety of internal corporate microprocessors with 801 risc processors (some number of Iliad chips). some of these floundered. the 4341 follow-on machine (4381) was nominally going to be a 801/risc processor (which got killed and different processor chip was used) ... although some subsequent low-end 370 processors did use 801/risc chip (i.e. significantly reduce the software development that had to be done each time for every new unique microprocessor)

the as/400 (s/38 follow-on) started out going to be a 801/risc Iliad ... but ran into troubles and eventually switched to a custom cisc chip. somewhat a decade later ... as/400 was moved to a 801/risc power/pc flavored platform.

some amount of folklore is that 801/risc chips are extensively used in various channel functions for current generation of mainframes.

You are full of it. Linux is written in C, not COBOL or Assembler. Also, there is not a different version of Linux for mainframes, the vast majority of the code is the same on all platforms. What is difference is memory management and of course I/O. This is done mostly through IFDEF statements in the Linux kernel C code. And the System z "changes" are integrated into the mainstream Linux code, not something kept separate by IBM.

Also, Linux is the NUMBER TWO operating system in the world now in terms of units (more than all other UNIX variants combined). It is the fastest growing operating system and will continue to grow.


as an aside ... as per various previous posts ... most of the mainframe unix ports in the 80s were products deployed under vm370 (uts, aix/370) ... in large part because field engineering and service people had requirement for mainframe EREP and RAS. the issue was that adding mainframe EREP and RAS to unix was a project several times larger effort than the port itself (i.e for those unix functions that existed ... porting/adapting as necessary to mainframe dependencies ... however, mainframe EREP and RAS were functions that didn't already exist). running under vm370, they could rely on vm370 to provide the mainframe EREP and RAS.

the primary exception was the special project for internal AT&T use ... which was adapting unix functions to sit ontop a stripped down tss/370 kernel.

some systems keep stuff in memory and didn't provide transaction acid semantics with what was on disk ... and so sacrificed integrity.

cms filesystem (dating back to mid-60s) kept stuff in memory, but always wrote control information to new location and then in case of failure ... recovery check whether to use the old (consistant) copy or a new (consistant) copy ... but never had a problem with their being an inconsistant copy.

relational implementations had multi-level index structure ... which was managed & updated with transaction semantics (always consistant). however, with the increase in real storage sizes ... increasing amounts/levels of the indexes could be kept in real storage (alliviating the multiple physical reads that had been required to find a specific disk location). however, any changes to these indexes (as well as the records themselves) conformed to transaction semantics and maintained consistency (both on disk and in real storage).

these relational implementations used "cache" for both indexes and actual data records ... managed somewhat analagous to how paging algorithms manage virtual memory in real storage ... or how processor caches operate ... but provide transaction semantics to guarantee consistency during any recover scenario.

unix started out using real-memory to cache filesystem control information ... but didn't guarantee any consistency about how changes done in real-memory got reflected back to disk. there are numerous folklore down thru the ages about momental unix filesystem disasters when glitches occurred at inopportune time. in fact, for a long time, unix rdbms implementations were done to "raw devices" ... totally bypassing any filesystem involvement.

the "in-core" dbms systems

would implement relational & transaction semantics ... but have default location of record in memory (as opposed to default location on disk) ... while still guaranteeing disk consistency for recovery ... and at the same time achieving ten times the thruput of equivalent DBMS relational database (running on same exact hardware) that used paradigm of default location on disk (aka via a different processes ... but somewhat the cms filesystem had been doing since the mid-60s for its control information). In fact, some people that i had worked with in research in the early 80s ... at least exposed to both the mechanics of the cms filesystem as well as the original relational/sql implementation

re:
https://www.garlic.com/~lynn/2008d.html#46 Throwaway cores

misc. past 801/risc posts
https://www.garlic.com/~lynn/subtopic.html#801

3830 supported dual channel interfaces ... and they were able to add ACP RPQ ... with logical locks (instead of just device reserve/release) ... with 512 "symbolic" lock fields. Both data and control paths went thru 3830.

3880 could have dual jib primes with 4channel interfaces each and handshaking/hand-off between the two processors. 3880 only had control paths thru jib-prime ... with data path flowing separately.

recent post with discussion
https://www.garlic.com/~lynn/2007i.html#33 Internal DASD Pathing

the above has discussion of subsequent (hardware) enhancement called "dynamic pathing" (also some corporate site URLs for 3380s).

one of the problems was that the jib primes handled control functions so much slower ... that operations took longer on the 3880 than the 3830 (even with jib-prime only handling control operations and data transfer being offloaded to custom hardware). one of the acceptance test for 3880 was that it performed within five perecent of 3830 ... which it initially failed. one of the gimicks to get 3880 within specs ... was to signal operation complete to the channel ... before jib-prime had completed some operation cleanup functions.

this resulted in flurry of problem for me. bldg 14 (disk engineering lab) and bldg 15 (disk product test lab) had been running "stand-alone" "testcell" testing. They had done some experiments with MVS with single "testcell" and experienced 15 mins MVS MTBF. So I had undertaken to build a system with absolutely bullet-proof input/output supervisor that wouldn't fail ... even when concurrently operating multiple testcells. misc. past posts getting to play disk engineer in bldgs. 14 & 15
https://www.garlic.com/~lynn/subtopic.html#disk

This worked out so well ... that they also started doing internal timesharing service (for engineers) on the same machines. At one point, bldg. 15 had gotten (one of the very first engineering) 3033s and scavenged 16 3330 drives & 3830 controller for internal timesharing service.

one monday morning i got a call from bldg. 15 asking what i had done to their system over the weekend. they claimed that timesharing response and thruput had severely degraded (and they had made no changes). Well after some investigation, they had swapped the 3830 with a 3880. more investigation was that the gimick/hack to signal completion was causing the problem. Nominally they figured that the 3880 could signal operation complete interrupt ... and the 3880 could complete clean-up overlapped with the operating system processing the interrupt ... and there would be no-foul. In large timesharing operation with multiple concurrent operations across multiple drives ... there could be queued requests for the controller. As soon as controller signaled complete, the operating system would redrive the controller with queued request ... which was hitting the 3880 while it was still busy. The 3880 then would have to reflect SM+BUSY (controller busy) ... the operating system requeues the operation and waits for the required CUE (control unit end) interrupt (required after having signaled controller busy). All of this additional back&forth plus the additional processing required in the 3880 ... severely degraded aggregate disk i/o to get through the 3880. As a result, they had to quickly generate a new hack/fix to make 3880 look like it was within 5percent of 3830 (at least from the standpoint of external single operation elapsed time measurement) . Fortunately all of this occurred six months before scheduled first customer ship for 3880.

This slower processing also significantly impacted the 3090. Besides the problem with operations taking longer elapsed time ... the jib-prime spent much longer connected to the channel (per operation). The 3090 was manufactured with a small number of TCMs ... and overall system thruput performance was modeled with a specific number of channels. When the severity of the 3880 increased channel busy became known, they realized that they would have to increase the default number of channels ... which necessitated adding an additional TCM ... which was a significant hit on increased manufacturing costs. There was some joke that the additional TCM costs per 3090 should be reflected against the disk division bottome line ... not the processor division.

As part of the input/output supervisor rewrite ... in addition to eliminating crashing and hangs ... i had also simplified the code and shortened the pathlength (part of it was the existing implementation had somewhat evolved spaghetti code implementation over nearly a decade). At the same time, I had greatly improved channel load balancing support ... for situation where there were multiple channel paths (from same processor) to common 3880 controllers and common disk pool (from earlier implementation where there was default primary path and some number of alternate paths used in case of failure or problems). It turns out that part of 3880 optimization was keeping information about channel path that disk i/o had previously occurred. On channel path changes, the 3880 was forced to do a huge amount of additional house keeping ... on the order of milliseconds ... that completely negated any possible benefits of any channel load balancing (i.e. thruput was actually greater with primary/alternate scheduling policy than with path load balancing strategy).

With reference to earlier reference to "dynamic pathing" (later models of 3880 having much faster processor and being able to switch paths much more efficiently) ... one of the issues that it was suppose to address was RPS-miss.

Recent post with regards to old claims I had made about disks having an order of magnitude reduction in relative system thruput over a period of more than decade (disks got faster ... but rest of the system got more than ten times faster than disks did)
https://www.garlic.com/~lynn/2008c.html#88 CPU time differences for the same job

the disk performance group got tasked with refuting my claims ... and eventually came back that i had slightly understated the problems ... specifically with respect to RPS-miss scenarios. old post mentioning dynamic path
https://www.garlic.com/~lynn/2001.html#18 Disk caching and file systems. Disk history...people forget

another (new) 3880 function, above also mentions 3880 disk caches ... i.e. initially 8mbytes, 3880-11 was 4k page record cache and 3880-13 was fulltrack cache. later there was upgrade from 8mbytes to 32mbytes, 3880-11 to 3880-21 and 3880-13 to 3880-23.

https://www.garlic.com/~lynn/2003e.html#65 801 (was Re: Reviving Multics

including (old) email asking if i was going to join in (risc) defections to other vendors

other reference in the above old email ... with respect to dedicated cores was a project called VAMPS that I got dragged into early '75 ... aka company was starting to recover from the disastrous forey into FS
https://www.garlic.com/~lynn/submain.html#futuresys

this was a 370 machine that had been designed with 9-position memory bus for microprocessors ... effectively all the same. Original design only called for single processor with microcode for 370 instruction execution ... the other processors would have custom microcode for various other dedicated functions (channel, control units, etc). however, most shipped machines were configured with only 4-5 memory bus positions occupied (with microprocessors)

project i got dragged into would have up to five of the memory bus positions populated with microprocessors with microcode loaded for 370 instruction execution ... aka 5-way 370 smp operation.
https://www.garlic.com/~lynn/submain.html#bounce

unfortunately, the product never shipped, however as part of the work (besides doing the multiprocessor kernel design) ... i took advantage of microcode availability to get fancy. I designed a queued multiprocessor dispatching interface aka queued interface that kernel software placed work on ... and the underlying microcode took work off of for execution (sort of reminiscent of later work for i432). I also did a queued i/o interface ... instead of strictly synchronous initiate/interrupt i/o paradigm ... somewhat akin to queued i/o that shows up later in 811 (started to ship in 370-xa).

and as before ... various past posts mentioning 801, fort knox, iliad, romp, rios, power, power/pc, etc.
https://www.garlic.com/~lynn/subtopic.html#801

for other drift, the same time as I got dragged into doing the VAMPS, 5-way smp 370 ... endicott also dragged me into doing ecps ... this predated the 4341 ... it was 370/145 follow-on; the 370/148. It had spare microcode capability and ecps was going to be virtual machine performance assist ... i.e. top 6kbyte instruction pathlengths in vm370 kernel moved into 148 microcode ... old post with early analysis details selected instruction paths to be moved to microcode

https://www.garlic.com/~lynn/94.html#27 370 ECPS VM microcode assist
https://www.garlic.com/~lynn/94.html#28 370 ECPS VM microcode assist

the issue in this scenario (for vertical microcode microprocessor) ... was that the typical microcode 360 & 370 emulation required 10:1 instruction execution ... avg of 10 microcode instructions for every 360/370 instruction (i.e. for 1mip 370, required 10mip microprocessor). As it turns out typical supervisor kernel 370 instructions would map nearly 1:1 to equivalent microprocessor instructions ... achieving a 10:1 performance improvement.

this is somewhat 30yrs gone ...

some number of this has all been encountered before ... recent thread in comp.arch mentioning 360/370 vertical microcode microprocessors having 10:1 execution ... i.e. avg. of 10 microcode instructions executed for every 360/370 instructions. this gave rise to "ECPS" on 138/148 & 43xx machines ... moving kernel code into microcode getting 10:1 performance improvement:

https://www.garlic.com/~lynn/2008d.html#54 Throwaway cores
https://www.garlic.com/~lynn/2008d.html#56 Throwaway cores

however, this was the low-end and mid-range 370s ... using vertical microcode microprocessors ... and wasn't true for the high-end machines using horizontal microcode microprocessors.

as also mentioned in the comp.arch thread ... the wide proliferation of different (vertical microcode) microprocessors (systems, controllers, channels, etc) resulted in projects circa 1980 to move corporation to single 801/risc microprocessor architecture (iliad chips). However, for various reasons this effort floundered. As mentioned, the 4341-follow-on (4381) started out being one of these 801/risc processors ... and I contributed to the writeups killing that strategy. the issue was that chips were getting complex enuf that it was starting to be possible to implement the 370 instructions directly in circuits ... rather than having intermediate microcode level.

now, the high-end product line was using horizontal microcode microprocessors ... this required extremely complex programming ... since different fields in the same instruction controlled different functions ... like starting a data move from one unit to another unit ... overlapped with variety of other functions. the programmer then had to manually count machine cycles (instructions) before the data could be expected to have finished the moved. because of the overlap complexity, these machines measured performance in the avg. machine cycles per 370 instruction (rather than avg. number of microcode instructions executed per 370 instruction). 370/165 was measured in an avg. of 2.1 machine cycles per 370 instruciton. this was optimized for 370/168 for an avg. of 1.6 machine cycles per 370 instruction. For 3033 it was approx. one machine cycle per 370 instruction.

this resulted in various problems .... ECPS virtual machine microcode assist on 148 & 4341 (i.e. moving part of the kernel instructions into microcode) got a 10:1 performance improvement. However, an attempt to do something similar on 3033 actually resulted in slight performance degradation (there was no gain doing a one-for-one translation from 370 instruction to 3033 native).

as in the discussion regarding virtual machine microcode assist:
https://www.garlic.com/~lynn/94.html#21 370 ECPS VM microcode assist
https://www.garlic.com/~lynn/94.html#27 370 ECPS VM microcode assist
https://www.garlic.com/~lynn/94.html#28 370 ECPS VM microcode assist

there was one set of (ECPS) things that just did a 1:1 kernel 370 instruction into microcode (for 10:1 performance improvement). there were another set of things that directly executed privilege instruction (but according to virtual machine rules) w/o interrupting into kernel. This later set of things showed performance improvements across all hardware implementations ... since it eliminated interrupts into the kernel, state change overhead, register save/restore overhead, etc (aka eliminated virtual machine kernel execution at all ... as opposed to trying to make the kernel execution run faster). this shows up in Amdahl hypervisor, 3090 pr/sm and current day LPARs.

in this day & age, the place where ECPS approach might be useful would be the intel platform 370 simulators (ala hercules implementation) ... where there is (again) the equivalent of vertical microcode implementing 370 instructions.

the slight caveat in all this is 370 architecture allowing self-modifying instructions ... supposedly half the cycles in many (earlier) hardware implementations, involved double checking whether the previous instruction has modified the current instruction (impacting instruction execution thruput).

current generations of chip technologies (not just mainframe chips) have significantly more complex implementations and enormous amounts of spare circuits. general chip technologies have implemented pipelined speculative execution ... associated with pipelining and not being able to tell for sure which branch path might be taken. speculative execution includes being able to undo instruction execution path (branch actually went the other way) ... something similar to speculative execution can be used to pipeline execution and then undo the operation if there has been self-modifying code.

recent post referencing pipelining and speculative execution for compensating for memory latencies &/or cache misses:
https://www.garlic.com/~lynn/2008c.html#92 CPU time differences for the same job

but hypothetically, technology could also be used as mechanism for dealing with self-modifying instruction streams.

up through 1999, (c-language related) buffer overflow exploits accounted for the majority of all internet related vulnerabilities.

the majority of these buffer overflow exploits wouldn't happen in PLI and PASCAL. They also wouldn't occur in 360 assembler conforming to standard system services (because os/360 system services avoided buffer length shortcoming convention that was part of common C language programming convention).

in the early part of this decade ... there was a big increase in internet-related exploits involving the greater use in some platforms and/or associated (personal) applications, which would automatically execute scripts arriving over the network. this increased until automagic script execution exploits were about equal to buffer length related exploits.

a couple past posts related to doing frequency analysis on the CVE vulnerability database ... and having difficulty categorizing exploits ... and lobbying the CVE interests to improve the strucuture/nature of CVE reports.

some amount of the problem was that common personal computer platforms had started out on stand-alone environment with possible terminal emulation connection
https://www.garlic.com/~lynn/subnetwork.html#emulation

and then LAN connections were introduced for local departmental networking. The automatic scripting grewup (as purely content enrichment enhancement) in a purely non-hostile environment.

The problem was treating the LAN connections, in a purely non-hostile departmental networking environment, as the same as LAN connections in the extremely hostile internet networking environment ... and not having evolved the appropriate countermeasures for the wide variety of possibly attacks.

actually many of the real clone vendors had gotten creamed when intel did the 386sx

far east clone vendors had built up huge inventory of 286 PCs over the summer ... anticipating an extremely rewarding xmas season ... which was undermined when intel announced/priced 368sx ... and a lot of last minute machines were produced with the 368sx. the huge 286 inventory eventually was unloaded at firesale prices.

most of the clone vendors were selling on cheaper price ... this dates back to mainframe clone controller vendors ... lots of past posts about getting blameed for the mainframe clone controller market after having participating in building one as an undergraduate
https://www.garlic.com/~lynn/submain.html#360pcm

and then later there were the mainframe processor clone vendors.

compaq wasn't so much selling into a "cheaper" clone price market segment ... they were selling into the business "portable" market segment ... and the cost of the (386dx) chip wasn't particularly an issue.

lots of companies were looking at selling 286-based PCs into the price sensitive market ... when Intel (effectively) blew them out of the market with the introduction of the 386sx (the 286 chips had already been sold ... so the 386sx was all brand new business).

part of the issue was that one of the executives from the mainframe division had been brought down to boca to head up the PS2 operation ... pure aside ... it was the same individual that had earlier con'ed my wife into doing a stint in POK in charge of (mainframe) loosely-coupled architecture
https://www.garlic.com/~lynn/submain.html#shareddata

one of the things the new PS2 executive did was contract with Dataquest (west coast technical marketing organization since bought by Gartner) for detailed study of where the PC market was going over the next 5-10 yrs. Part of the study was several hr (video tapes and transcribed) round-table discussion with 10-12 experts from silicon valley.

Dataquest contacted me to be one of the experts. The problem was that i had been heckling boca (internally) for years about where the market was at and where it was going ... and they simply ignored me. Since I was in the same corporation, but a different division ... I did get executive approval (from my division) to participate in the videotape dataquest roundtable ... so long as dataquest garbled my identity ... so the PS2 division executives wouldn't easily recognize who i was.

Why do graphics belong on the server anyway? I don't want a Windows server to do the pretty graphics either. Put the pretty stuff on the client side, and put the data on the server side.

this was a battle that the disk division had with the communication division. in the late 80s at an internal world-wide communication division conference ... a senior technical person from the disk division started their talk by saying that the head of the communication division was going to be responsible for the demise of the disk division (and would everybody in the audience please call the ceo to voice their concern).

the problem was that communication division had helped with the rapid uptake of PCs with terminal emulation. however, by the late 80s, the terminal emulation paradigm was starting to represent a severe bottleneck. the disk division had numerous products in the works to eliminate most of the problems ... however the products were all being block by the communication division protecting their terminal emulation install base.
https://www.garlic.com/~lynn/subnetwork.html#emulation

the frustration with the communication division blocking all of these products contributed to the subterfuge behind the presentation ... and the opening remarks.

the issue was, as work-around to the enormous impedence represented by the terminal emaulation paradigm, ... data was leaking out of the glass house in almost every way possible ... being replicated on local PCs and servers (outside the glass house).

in this period ... the communication division had also come up with SAA ... which could be construed as an alternative to client/server paradigm ... and attempting to preserve the terminal emulation install base.

in the same period ... we had come up with 3-tier networking architecture and were out making customer executive presentations (and taking all sort of barbs and arrows from the SAA forces).
https://www.garlic.com/~lynn/subnetwork.html#3tier

one of the battles that the senior tech guy (that gave the talk about the demise of the disk division) fought and lost was over the channel interface box for mainframe tcp/ip product. The product that shipped got 44kbytes/sec consuming a 3090 processor. I added rfc 1044 support to the product (for different vendor box), and in some tuning tests at cray research between 4341-clone and cray got 1mbyte/sec (4341 channel speed) using only modest about of the 4341 (around three orders magnitude improvement in bytes transferred per instruction executed).
https://www.garlic.com/~lynn/subnetwork.html#1044

another example was the 8-way vm/4341 cluster support done by research. internally it used a custom protocol over 3088/trotter (8-arm channel-to-channel). For product ship they were required to convert to sna. An example was the internal implementation would perform the cluster synchronization function in under a second elapsed time. The sna flavor took over 30seconds elapsed time to perform the same operation.

Given how much work it was to design a processor (or channel) from scratch, I could easily imagine that the standalone channels could have been derived from the 360/50 CPU design or the like. (Or maybe even the 360/30 or 360/40, though those had narrower data paths which would have required adding extra logic to assemble and disassemble 32-bit words.)

I was undergraduate in that period. closest i came was some of the work that dealt with reverse engineering the channel interface (on 360/65 ... but didn't get into what the processor was like in the external channel box) ... as part of implementating a channel interface card for interdata/3 ... implementing a 2702 clone

No, suppose that the VM has its own memory management such that loads and stores can spill off to the filesystem just like page faults work for the host OS. For example, imagine a VM for a 64-bit processor running on a 32-bit processor. Conceivably the VM could run apps with far larger datasets than the real processor.

part i:

so imagine the original 801/risc from the mid-70s ... it has 32bit addressing ... 16 segment registers ... each one being able to select 256mbytes each. part of the design was significantly simplified hardware ... compensating by features in software. the program loader would only load code (for execution) from a valid pl.8 compiler ... and the pl.8 compiler would only generate correct code. the result was that "inlineq" code would easily change segment register values as easily as general (and/or address) registers could be change.

there was no using virtual address space to partition different applications from each other ... and/or requiring kernel calls to make modifications to virtual address space specification. there was no hardware protection and/or privilege mode ... i.e. no application execution not being able to execute certain instructions (ala changing segment register contents).

so we come up to romp in the early 80s ... joint research, office products 801/risc chip to be used as follow-on for the displaywriter. 801/risc was inverted tables ... so segment register contents were just unique identification associated with each segment (not a table pointer). romp segment registers were 12 bits. under the philosophy that segment registers could be changed by inline application code ... as easily as general/address registers ... the machine was claimed to be "40bit" virtual addressing.

addresses were actually only 32bits ... top four bits selecting one of the 16segment registers ... and 28bits selecting displacement within 256mbyte segment. since the value in a selected segment register could actually be one of 4096 segments ... the claim was it actually was a 28bit+12bit = 40bit addressing machine.

even after the displaywriter follow-on project was killed and it was decided to retarget the machine to the unix workstation market ... the claim of 40bit addressing continue to hangon. hardware privilege mode had to be added, requiring kernel calls to update segment registers ... in order to adapt it to unix paradigm ... the 40bit description still shows up in documentation. imagine it as if there was aggregate 40bit virtual address space .... effectively with 16 256mbyte "windows" that could be randomly moved around the actual space (maximum of 4gbyte concurrent at a time).

rios doubled the segment register value field to 24bits ... and even tho the machines had long been adapted to unix paradigm ... still 32bit virtual address spaces ... and some documentation still describing the machine as having 52bit address space.

re:
https://www.garlic.com/~lynn/2008d.html#68 Regarding the virtual machines.

part 2 .... a different paradigm is the mainframe access register scenario.

mainframe batch systems from the 60s have everything in (single) real storage heavily implementing pointer passing api. transition to virtual memory first simulated a single 16mbyte virtual memory (as if it were real) ... then the transition was to a single 16mbyte virtual memory per application. however, the heavy use of pointer passing api ... resulted in the kernel appearing as 8mbyte of each application 16mbyte virtual address space.

there was a remaining problem with lots of "subsystem" applications that were outside the kernel ... and had been moved into their individual virtual address spaces ... however regular applications still continue to use pointer passing apis to these subsystem operations in different address spaces. the temporary solution was something called a "common segment" that appears in all address spaces ... which an application can use to squirrel away data and then use pointer-passing api to invoke a subsystem in different address space. problem was at large installations, having common segment growing to 5mbytes or more (16 mbyte virtual address space per application, 8mbyte dedicated for kernel image, and 5mbytes or more for common segment image, leaving 3mbytes or less for application).

late '70s mainframes (with 3033), "dual-address" space was introduced ... semi-privilege subsystems had two virtual address spaces that they could access ... their primary virtual address space ... and (secondary) virtual address space of the calling applciation.

early 80s, 31bit virtual address space was added ... but still required multiple virtual address spaces that could be accessed simultaneously. along the way special hardware program call (& return) was added. rather than having to pass thru kernel call to switch address space when calling a "subsystem" ... special hardware tables were setup that defined directly callable subystems along with the rules regarding virtual address spaces required. in effect, directly calleable library routines can now reside in different virtual address spaces.

as to the original question

this concurrent virtual address space operations continues into current 64bit address machines
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dz9zr003/CCONTENTS

address spaces summary:
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dz9zr003/3.8?DT=20040504121320

from above:
At any instant when the CPU is in the primary-space mode or secondary-space mode, the CPU can translate virtual addresses belonging to two address spaces -- the primary address space and the secondary address space. At any instant when the CPU is in the access-register mode, it can translate virtual addresses of up to 16 address spaces -- the primary address space and up to 15 AR-specified address spaces. At any instant when the CPU is in the home-space mode, it can translate virtual addresses of the home address space.

re:
https://www.garlic.com/~lynn/2008d.html#64 Interesting ibm about the myths of the Mainframe

my wife had co-authored peer-to-peer networking architecture ... AWP39 ... in the time-frame of early sna. note that only in an institution where the term "network" had been usurped for communication protocols ... would be necessary to qualify networking with "peer-to-peer".

later she was con'ed into going to pok to be in charge in loosely-coupled architecture ... where she did peer-coupled shared data architecture
https://www.garlic.com/~lynn/submain.html#shareddata

which saw little uptake until sysplex, except for ims hot-standby; ... which contributed to her short tenure in the position. other factors were constant battles with the communication group. at one point, they sort of reached a temporary truce; sna would be used for anything that crossed the walls of the glasshouse ... but she could do her own thing within the boundaries of the glasshouse. as can be seen in the previous vm/4341 cluster reference ... the truce didn't last very long.

in this recent post, there is discussion of working with educational institutions and nsf
https://www.garlic.com/~lynn/2008d.html#43 more on (the new 40+ yr old) virtualization

and getting waylayed by internal politics and not being allowed to deploy the nsfnet backbone. some old email from the period
https://www.garlic.com/~lynn/lhwemail.html#nsfnet

one of the above referenced emails, was forwarded to us by one of the other AWP39 co-authors ... which showed some amount of internal pontificating about how nsfnet would be able to take advantage of sna
https://www.garlic.com/~lynn/2006w.html#email870109

the NSF director had thot that sponsoring an audit of highspeed backbone that we already had running internallly ("at least five years ahead of all nsfnet bid submissions", to build something new) and writing a letter to the company 3Apr1986, NSF Director to IBM Chief Scientist and IBM Senior VP and director of Research, copying IBM CEO), ... would help the situation. however, it just appeared to aggravate the internal politics.

to sort of position AWP39 (peer-to-peer networking architecture) .... much later, appn was AWP164. At the time they were trying to announce appn ... the person responsible for appn and I directly reported to the same executive. the communication group objected to appn announcement. after some political escalation, the appn announcement letter was carefully rewritten to avoid implying any sort of relationship between sna and appn (also delaying the announcement by approx. two months).

If someone can tell me the price of a CPU second in a larger z/OS system (we discuss currently if 0.5% CPU usage is relevant or not )

part of the issue is total annual amortized capital costs (physical facilities, computers, disks, etc ) plus total annual expenses (utilities, telecom, power, water, software, people, etc) ... purely hypothetically $20m.

old article that mentions dec2004, there were 124,478 line items of software pricing:
http://www.zjournal.com/index.cfm?section=article&aid=258

then the issue is how cost recovery is achieved ... is it solely based on processor time charges ... or are other resources, like number i/os and storage space utilization, also priced ... contributing to infrastructure cost recovery.

even if it is just based on processor time charges (no other resource consumption billable charges) ... there is issue of capture ratio ... aka what percent of processor time actually shows up in accounting records. say processor avgs 50% busy, 7x24 ... and capture ratio is 50percent ... which could result in 42 processor billable hrs per week ... hypothetically 2184 billable hrs per year.

then hypothetical break-even would be $2.55/billable-processor-second.

if there were actually ten individual processors that made up the computer (CEC) ... then the actual billable processor hrs (in hypothetical example) could be ten times larger ... and break-even would be $.26/billable-processor-second.

there was recent articles that some number of companies are putting in large datacenters around the columbia river ... some search engine results:
http://www.isedb.com/db/blogs/1740/Size-Matters---Mega-Datacenters-Being-Built-Along-Columbia-River.html

as student ... i had been brought in for the summer (as full time employee) to help get BCS going. BCS objective was to consolidate the internal datacenters ... sort of moving them from cost center to a P&L center ... at least on paper ... however, not just selling services internally ... but also enabled to sell/market services externally (some idea of showing billed revenue covering business unit costs).

So software is not the only discipline where the longer a defect stays in the process, the more expensive it is to fix. It's also not the only discipline where a "top down" design, made in ignorance of detailed bottom-up knowledge, leads to problems. There is however a difference here between design and requirements. The requirements for the engine were clear and well defined. You know, go to space and back, preferably without blowing up. Feynman is arguing not so much against Joel's functional specs, but rather against top down design such as that advocated by the UML as blueprint crowd.

In terms of oil, we have probably extracted around 40% of what was there originally. It is just that the very last 40% of any field are very slow and expensive to extract.

it was something like two decades ago where there was work on pumping water into oil fields to aid in extracting additional oil ... and then there was story about suspending the activity. apparently the scenario was that the water could possibly lubricate fault lines ... placing the companies at risk of legal action if there ever was earthquake damage (claims that any earthquakes were a direct result of pumping water into the ground).

Around 1990 I worked at the IBM Kingston NY facility on a "native" port of AIX to the 3030? mainframe.

My take on the project: it was IBM's "not invented here" resentment that a contractor (California's Convergent Technologies) successfully delivered AIX for the PS/2 and mainframe. They were clustered and tightly coupled using TCF (Transparent Computing Facility a/k/a Totally Confusing Facility). All machines in the cluster shared the process table, mount table, etc. so running processes could migrate to any available machine (of same CPU) without checkpoint/restart (unless that was done under the wrappers to the migrate system call). I rather doubt the project got very far due to internal politics.

The managers were too busy protecting their own interests to bother with the project.

My understanding is that an IBM group in Austin, Texas did the rs/6000 AIX port, so they were wonderfully isolated from such politics. It simply worked and sold well!


it would have been a "3090"

the palo alto science center group had been working with UCLA and had a locus port both running on some 68k machines and on series/1 in the early to mid 80s. then they also picked up effort to port (Berkeley) BSD to 370 in the mid 80s. I did some consulting with that group on c compiler and 370. at some point that group spun off and moved into a different bldg across grassy quad (from the bldg. that science center was in).

the austin group had started out using 801/risc romp chip for opd displaywriter follow-on. when that project was killed they look around and decided to retarget the machine for unix workstation market. the company that had done the pc/ix port was hired to do similar port to romp. this was announced as the pc/rt and aix. misc. posts mentioning 801, risc, romp, rios, power, power/pc, etc
https://www.garlic.com/~lynn/subtopic.html#801

the palo alto group then was redirected to take the 370 BSD port that they were working on ... and instead retarget to the pc/rt ... which was announced as "AOS". by this time, i believe the (unix related) palo alto group had been moved into the (new, academic and university) "ACIS" division.

the austin group then did a 801/risc romp follow-on chip called rios ... which was announced as pc/rt follow-on, the rs/6000. and the pc/rt aix (v2, sort of to differentiate from pc/ix on pc) ... was moved to rios and announced as aix v3.

the palo alto group then took some of the ucla locus work that they had been and did both a 370 and a 386 version ... this was sort of the SAA equivalent for the unix world. I don't remember any dealings with any outside contractors that may have been involved in the ucla locus work (other than some of the people from LA that had been involved with ucla locus).

the austin group then got heavily involved with OSF and DCE, recent references:
https://www.garlic.com/~lynn/2008b.html#20 folklore indeed
https://www.garlic.com/~lynn/2008c.html#53 Migration from Mainframe to othre platforms - the othe bell?

which involved austin's distributed file system work, but also andrew & mach work at cmu, locus work at ucla, some mit project athena work ... and other technologies from various operations.

i can see where hudson valley viewed alternative kernels for mainframes as NIH ... vis-a-vis their own favorite son offering. There was somewhat similar situation between Austin (with "AIX" which they had taken as their strategic operating system) ... vis-a-vis ACIS "AOS" offering for pc/rt (especially since ACIS had significantly upstaged Austin in doing the BSD/AOS port ... orders of magnitude less resources and elapsed time).

there was similar NIH attitude in hudson valley towards science center's virtual machine operating system (initially cp67 and then vm370 when ported to 370). an example was the internal HONE timesharing system which provided the worldwide service to sales&marketing operation.
https://www.garlic.com/~lynn/subtopic.html#hone

A lot of (internal) vm370 enhancements went into HONE in the late 70s for clustering the US HONE operation (supporting all US sales & marketing at cal. datacenter) ... which requiried load balancing across max. collection of loosely-coupled SMP machines (single system image). Then because of disaster considerations (earthquakes in cal.), in the early 80s, the operation was extended to geographic loosely-coupled ... first with replicated datacenter in Dallas and then a 3rd in Boulder.

recent tale of repeated series of (disastrous, unsuccessful) efforts to try and get HONE moved to MVS-based operation:

trivia ... the cal. hone datacenter was across the back parking lot from the complex where the science center and the acis group were located:

the displaywriter follow-on was cp.r operating system and pl.8 programming language. when the decision was made to retarget to unix workstation market ... and the company that had done the pc/ix port was hired to do unix port to romp (i.e. pc/rt, for aixv2) ... they needed something to do for all the pl.8 programmers.

something was defined called the VRM (virtual resource manager) which was sort of a abstract virtual machine layer (implemented in pl.8). the group that had done pc/ix was instructed to port to the VRM layer, not the real machine. The justification was that the resources and elapsed time to do VRM plus unix port to VRM ... was less than doing unix port directly to the real hardware.

part of the later issue with the palo alto group doing a bsd port directly to the romp 801/rsc chip for "AOS" ... was that it was done in less effort than just the unix port to the VRM interface. the VRM strategy also had other long-term implications ... like duplicate new device drivers ... one in the VRM layer and another in the unix layer.

a lot of the morph of aix v2 to aix v3 for rs/6000 was the elimination of all the VRM stuff.

'Gecko' Penetrates Building Access Systems; Black Hat researcher builds device that lets intruders steal and clone legitimate credentials from biometric and contactless card-based systems
http://www.darkreading.com/document.asp?doc_id=146718

from above:
In the Gecko demo, a Black Hat volunteer scanned a legitimate access card through the reader, and then fellow researcher Adam Laurie -- acting as the bad guy -- was able to piggyback off of her access code with his own card and gain entry. He was also able to disable her card and enable his.

Franken said Version 2 of Gecko will store multiple identities in Flash memory, and Version 3 will include a Bluetooth interface that can fake out biometric scanners that don't use proximity cards. "Version 3 is ideal for biometric devices," he said.

Version 4, meanwhile, will come with a GSM interface, Franken said, and would let an attacker open a door remotely.

• fixed hardware storage area (HSA) of 16 GB, so users won't have to sacrifice memory for HSA any longer;
• an integrated hardware decimal floating-point processor to aid with financial and enterprise resource planning applications;
• a reduction in power-on reset (POR), which could enable the ability to reassign additional logical partition (LPAR) resources without compromising application performance; and
• a feature called HiperDispatch, the details of which are unclear.

alr advertises 386/2m10 w/1meg memory for $1990. If somebody was really interested in LAN-environment workstation they should be able to eliminate some of the expansion slots and put the 2.5mbit lanstar appletalk interface on the mother board for about the same price (using LAN to access fileserver with majority of system and applications, files, etc).

problem for aix/386 is its so memory hungry. vm/386 with one of unix environment emulators would fit in bettter. Even at $100/mbyte, aix/386 would push the price up close to $2500 to configure reasonable memory.

also notice tandon advertisement for 40mbyte portable winchester hard disk (or "self-contained, portable Personal Data Pacs") for $350 (<$10/mbyte).

"New Directions" quotes Intel as '89 being the year of the 25mhz 386 and 386-based workstations for <$1000 are coming. Unfortunately in that time-frame they are likely to find 32mhz 68030s workstations.

Everex Systems has 2mb memory expansion board for ps/2 for $399 (just under $200/mbyte) using 1mbit dram chips

Maybe it would be possible to get 386 LAN-workstations with 4mbytes & 2.54mbit Appletalk Lanstar interface on the motherboard for just over $2k. But then presumably Apple could do something similar with a 32mhz 68030 ... then maybe entry-level machine with 68020, 1mbyte memory and appletalk interface on the motherboard could be had for $1k. Presumably Apple will announce its UNIX this month at their yearly meeting.

Subject: Byte-striping DASD

Saw in this week's Computerworld an article which said Micropolis had announced such a beast. Uses five 5.25 inch drives of 380Mbytes each, each drive has 1.25Mb/sec data rate and the conglomerate is rated at 4Mb/sec. It appears to the computer as a single 1.5Gb drive with a SCSI interface.

Four drives hold data, while a 5th holds parity data. Sells for $12000 to OEMs; samples will be available THIS QUARTER. This technology holds at least two potential advantages: (a) data rate can be dramatically speeded up, as can be seen above, and (b) reliablity is drastically increased. In this case, if any of the five drives goes bad it can be replaced with a new one WITH NO LOSS OF DATA AT ALL, and little/no downtime of the DASD as seen by the CPU.

Perhaps I'm just out of touch, but this is the first product of this type I've seen announced (though it's been talked about for some time). So who needs 3380s?

o MINISCRIBE, in attempt to KEEP customers FROM SWITCHING to 3.5in drives, has a "featured" 85MB 5.25in drive, described in brief 40, which will list for under $700 vs. $845, for say, Quantums 3.5in 85MB 3.5in drive.

o MAXTOR's subsidiary, Storage Dimensions, has extended its LANstor 5.25in drives as subsystems supporting Novell's NetWare Ver. 2.1; prices range from $3,095 to $22,530 (37);--introduced SpeedStor 133 to compete with PRIAM's InnerSpace, also REDUCED PRICES of 120MB SpeedStor for DOS sys- tems by $500 to $2,495 (38).

You never had any decent ISDN penetration. You still run pulse dialling on phones. There are still oodles of T1's with R-mode signalling (i.e. digital lines, but no ISDN). The Internet deployment by telcos are abysmal, only where they have competition by cable etc is there any decent service. GSM/UMTS Mobile phones have been delayed by two decades, and there is still no decent roaming. And you could have leapfrogged to UMTS, but didn't.

some of ISDN penetration was figuring out how to charge ... analogous to the nsfnet backbone discussion where the telcos couldn't figure out how to change the revenue model (chicken & egg, how to reduce tariffs significantly to encourage the bandwidth hungry applications ... w/o first having the bandwidth hungry applications consuming huge amounts of bandwidth)
https://www.garlic.com/~lynn/2008d.html#43 more on (the new 40+ yr old) virtualization

in the mid-90s, i had isdn for awhile ... 4cents/min per 56kbit channel (telco charges) to local isp (in addition to isp subscription). avg. over $500/month. that is compared to flat rate phone line $30/month for with 28kbit modem to local isp. I eventually got dsl.

later i moved and found there wasn't dsl (or cable) ... telco offered to install T1 frame-relay at $1200/month
