two people from the Los Gatos VLSI lab originally did mainframe pascal for VLSI chip tools ... this goes on eventually to become the vs/pascal product. Amoung other things it was used to implement the original mainframe TCP/IP support. It originally had some performance issues ... getting around 44kbytes/sec throughput using 3090 processor. However, I did the RFC1044 changes and in some tuning tests at Cray Research got sustained channel media throughput between Cray and 4341 using only modest amount of the 4341 processor (possibly 500 times improvement in bytes moved per instruction executed). past posts mentioning doing rfc 1044 support http://www.garlic.com/~lynn/subnetwork.html#1044 One of the issues is the (pascal) implementation had none of the exploits that have been epidemic in c-language implementions ... observation it is about as hard for a programmer to *NOT* have such exploits in c-language as it is for a pascal programmer to have such problems. past posts mentioning c-language exploits http://www.garlic.com/~lynn/subintegrity.html#buffer in the period that IBM had gone into the red and was re-organized into the 13 "baby blues" in preparation for breaking up the company (until the board brought in Gerstner who reversed the breakup and resurrect the company) ... there was big move for business operations to get off of proprietary tools & platforms. Part of this was to transfer proprietary tools to standard industry tool vendors and get them running on industry standar platforms. I had to do one such pascal 50,000+ lines of code vlsi application. Problem was that pascal on some of these other platforms appeared to have been used for little else than introduction to programming classes (one such platform was in the local area, but they had outsourced their pascal support to someplace 12 time zones away, located near a space launch center). -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
