      A better question is why geeks would have a fetish for Crays at all these days, other than those with a historical bent. Believe it or not its not like you are going to have some transcendent experience logging in to one, unless you really get off on Fortran and vectorizing code. Obviously they have some fine massively parallel machines but so do a lot of other companies. If you have an app that you want to run that fits on a Cray then maybe its still interesting to you but thats not most people.

      OS wise they do have some good software for niches, but in general Linux is better and more broadly developed, and of course some of Cray's machines are running Linux too. CrayOS has never had the critical mass of developers you need to be polished, though again in certain niches it has some really great efforts.

      Big Iron had its place a decade ago and back. The tyranny of Carer Mead and CMOS processors has led to an age were smaller, cheaper and mass produced trumps big, expensive and custom built for most, though certainly not all, applications.

      For example its why most of us are running Nvidia and ATI GPU's and not SGI big iron graphics anymore. And of course SGI's R8000 among others carved up the low to middle end of Cray's market and ended their last incarnation as an independent company.

      Good point. Here's how to get the experience, or something close to it. First, get a Pentium III machine, maybe 800Mhz processor. Fill it up with at least a gig of memory, and a terabyte of disk space, implemented as a large array of IOMega Bernoulli drives, 40 megabytes each. Install Linux on it. No, not Redhat, I mean Slackware. Do not install the X server. Install your Fortran compiler. Oh, and I forgot to mention, you will interact with this machine through a VAX front end. You won't log into the machine directly, but will work on the VAX and submit jobs from the VAX to the simulated supercomputer. When the job is done, the results are sent back to the VAX front end computer.

      Ta Da! You've got a machine that's very comparable to a Cray I from more than 20 years ago.

      I recall studying an early (Nazi Germany era) jet engine. It had all kinds of very sophisticate systems (e.g. liquid cooled turbine blades) to get around metalurgical limitations. Some of the features actually went from nearly 50 years before they were implemented again when materials technologies were a limitation and exotic work-arounds were required.

      Yes, history may have passed these CRAY machines by, but the engineering problems once solved may be encountered again and it would be a shame to disregard that research because the "big iron" is "old iron".

      It's not about the machine, as much as the man and the philosophy behind the machine.

      Seymour Cray was one of the first true legends of computing. His mixture of sheer architectural intelligence and interesting personality quirks made him one of computing's first media stars (for small niche values of media). His architectural philosophy was to do one thing and do it well. For example, the main issue leading to his break with CDC was that they wanted the new generation of Cybers to be multi-purpose, while Seymour wanted to crunch scientific bits really, really fast.

      If you look at the processors he designed, there were almost never any architectural compromises to his goal of making the machine having the most FLOPs. If that meant memory had no parity (His quote: "Parity is for farmers.") so be it. If it meant new cooling technologies, he'd design it. If it meant a design of a new chip, he'd do it. That sort of single-minded devotion to architectural purity is pretty much unknown today, because companies aren't interested in pushing the technological envelope the way Seymour did. And that's why Cray's are legendary - something that an SGI or Intel multi-processor never will be.

      I haven't actually RTFA but the two models listed in the submission aren't actually Seymour's designs. The T90 is Seymour inspired but I don't think he was anywhere near where it was built. I don't think the T3E has anything to with him, and am not sure he would have liked it much since its kind of a commodity CMOS(DEC Alpha) based MPP and nothing like anything Seymour would have designed. Thats one of the problems with Cray's deity status, his name has been tacked on so many companies and computers at this point its diluted his "brand" and that is unfortunately what his name is today, a brand that that doesn't have anything to do with the man anymore.

      "because companies aren't interested in pushing the technological envelope the way Seymour did."

      Maybe its because after the Cray-2 and its derivatives Seymour's approach stopped working. There was only one Cray 3 built, it was at NCAR if I recall, and the Cray 4 was never finished. His need to push the envelope pushed him to GaAs and GaAs was hard to make work and very expensive, the antithesis of the commodity CMOS that won. Maybe he could have made it work if he'd had more money and lived. But the fact is commodity CMOS won for some good reasons.

      Its also worth looking at his efforts at CDC on the 6600, 7600 and 8600, while offering amazing performance for the time, and quite successful, developing them nearly bankrupted CDC. Its a lot easier to "push the envelope" if you have buckets of money, presumably from government subsidies than it is if you are trying to keep a company afloat. Not sure you've ever run a company but its not easy, and Seymour's, spare no expense approach tended to give the people trying to balance the books fits.

      He was a GREAT engineer and he made some major contributions to computer engineering. Not sure I would go so far as to deify him.

A single branching instruction usually resulted in a task switch to the next queued process, thus keeping processor usage high.
