Update From Cray World
rchatterjee writes "Cray, the only mainstream recognizeable name in supercomputing, has been busy lately. Their totally new MTA-2 supercomputer design will use a UltraSPARC-III powered Sun Fire 6800 server to just feed the data to the MTA-2's processor. They're also refocussing on Vector Supercomputers and are going to release their first new vector supercomputer since Tera Computing bought them, the SV-2 in 2002. And if that wasn't enough they have a deal with API networks to develop Alpha processor based Beowulf clusters of Linux machines that as a cluster will run the same operating system as Cray's T3E supercomputers. Seymour Cray would be proud. You can get a quick overview of all the latest Cray developments from this article on Cnet."
Okay, I'm a NEC/HNSX Supercomputers employee, on the verge of becoming a Cray employee (because of the agreement they signed), but I'm not speaking for anyone else but me here, of course. :-)
I don't know why people bother with such a news. Sun's gonna provide the I/O processor for a not-so-high-end supercomputer. And?
A few weeks ago, there was a real bombshell: Cray would drop the anti-dumping legal action, re-opening the US market to japanese supercomputers. Cray will even become the sole reseller of the NEC SX Series in North America!
If you go take a look at www.cray.com, you'll see that this agreement with Sun occupies a single line in their news listing, while the NEC agreement is a big framed box that occupies about half of my screen here.
For some time now, american supercomputer customers were petitioning to get japanese machines, because it been a long time the american machines had been up to any good. Instead, we hear about the SV2, which will barely surpass the few years old SX-5 processing power, with less memory throughput than the SX-5.
I won't deal with the "no need for big clunky vector supercomputers, we have clusters". I believe a whole lot into clusters, but they're freakin' hard to program, and some things just won't be as fast (hey, the SX-5 CPU has a 256 bytes wide memory path! that's not bits, that's bytes! what can you do with your puny gigabit ethernet cluster interconnections?).
Look at these bandwidth benchmark scores. The closest thing to a cluster, the Origin machines, are literally crushed to bits by the SX-5. And they're doing twice as good than the SV1.
As for using old big iron machines for stuff like fridges and so on, there was a cool thing at one of our customer site, at the University of Stuttgart: a Cray coffee table. :-)
Nothing beats talking about supercomputer technology while drinking some orange juice on top of a Cray machine. NOTHING.
