View Full Version : Cray supercomputer is world's fastest (that we're allowed to know about)

Seattle-based Cray has been wowing us with massive, ridiculously fast supercomputers since the '70s, establishing a position for its machines high on every geek's most wanted list -- despite never publishing a Doom benchmark. In recent years the title of "world's fastest" supercomputer had been lost by the company, ping-ponging from Wako, Japan (http://www.engadget.com/2006/07/31/japanese-supercomputer-breaks-the-petaflop-barrier/) to Armonk, NY (http://www.engadget.com/2008/06/09/worlds-fastest-ibms-roadrunner-supercomputer-breaks-petaflop/), but is now back in Cray's hands with the implementation of the XT Jaguar. It's comprised of over 45,000 quad-core Opteron (http://www.engadget.com/tag/opteron) processors, 362GBTB of memory, and has a 10PB (petabyte) storage array, able to perform calculations at a massive 1.64 petaflops. That's over one and a half quadrillion operations per second and more than 50 percent faster than IBM's previous heavyweight. Mind you, Cray is quick to point out that this is the fastest machine being used for non-classified research, a caveat that just makes us even more curious about what's keeping the Pentagon's server rooms warm and loud... and apparently orange.

Amazing! I'm still trying to get a good deal on a 1TB hard drive! ;)

WOW :eek::eek::eek:

Yea thats some heavy duty power there. I wonder what they use it for.

While titles like "world's fastest" and "world's largest" are fleeting at best, it's rare that we see such things taken down this quickly. Last week Cray delivered a big dish of braggadocio, talking up its 1.64 petaflop XT Jaguar supercomputer (http://www.engadget.com/2008/11/12/cray-supercomputer-is-worlds-fastest-that-were-allowed-to-kno/) as the fastest (non-classified) machine in the world. Now, like some rocket skate-wearing coyote who's run out of thrust, it's been stymied by IBM's Roadrunner, deployed at Los Alamos (http://www.engadget.com/tag/LosAlamosNationalLaboratory/). TOP500 (http://www.engadget.com/tag/Top500/) is the authority on these matters and that list's latest rankings place Roadrunner in first place with a speed of 1.105 petaflops; Cray's Jag comes in second with a paltry 1.059. What about that 1.64 figure from last week? That was the hypothetical limit, and while it did deliver real-world performance of 1.3 petaflops for the folks at Oak Ridge (http://www.engadget.com/tag/Oak+Ridge+National+Laboratory/), TOP500 relies on the Linpack benchmark for its ratings and apparently the Jag just couldn't deliver the goods there. Perhaps, Cray, it's time to make another call to ACME -- or AMD as it were.
