IBM Kingston supposedly had the responsibility for doing new supercomputer ... also was providing to Chen's endevor (responsible for both xmp & ymp) https://en.wikipedia.org/wiki/Steve_Chen_%28computer_engineer%29 we were doing cluster scaleup as part of HA/CMP ... past posts http://www.garlic.com/~lynn/subtopic.html#hacmp then end of Oct91, the senior executive backing Kingston effort retires and there is audit of all his projects. After that they start scouring the company looking for high performance technology. Jan1992 meeting in ellison's conference room about (commerical) cluster HA/CMP scaleup http://www.garlic.com/~lynn/95.html#13 mainframe DB2 complaining if we were allowed to go ahead, it would be years ahead of them. Then cluster scaleup is transferred, announced as supercomputer (for technical & scientific *ONLY*) and we were told that we can't work on anything with more than four processors (which motivates us to leave). Somewhat no brainer operations ... it takes care of the DB2 complaints and also gets them their supercomputer ... old email about working on technical and scientific with national labs and others (up until the transfer) http://www.garlic.com/~lynn/lhwemail.html#medusa 17Feb1992 press, scientific and technical *ONLY* http://www.garlic.com/~lynn/2001n.html#6000clusters1 05May1992 press, total surprise about national lab interest http://www.garlic.com/~lynn/2001n.html#6000clusters2 I would claim that (national lab) scientific & technical activity traces back to at least getting roped into doing LLNL benchmark looking at getting 70 4341s for computer farm and RDBMS/commercial dates back to BofA getting 60 4341s for branch office distributed System/R (original relational/sql implementation). Note that IBM's RDBMS were mainframe only and so RS/6000 had to work with other RDBMS for their platform. It turns out that a couple of those vendors had same source base for both VMS cluster as well as open systems. Part of simplifying the HA/CMP cluster scaleup was providing interface that supported VMS cluster semantics. These RDBMS vendors also had some very strong feeling about some of the VMS cluster implementation that could be done much better (which I was able to take advantage of besides my experience doing mainframe tightly-coupled and loosely-coupled implementations). Later in the 90s, Chen is CTO at Sequent and we do some consulting work for him (before IBM buys Sequent and shuts it down). -- 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
