Cray XT Jaguar: 45,000 QC Opterons
Cray is no stranger to the supercomputing world — it’s practically the pioneer in the field. This week, the department of energy (DOE) announced that it has completed the setup of a new Cray XT Jaguar supercomputer that breaks all world records, claiming to be the fastest supercomputer on Earth.
The monstrous machine is made up of 45,000 quad-core AMD Opteron processors. As a frame of reference, that’s a mind boggling 180,000 cores. And here I am getting excited over my dual quad-core machine. In terms of memory, the XT Jaguar is outfitted with 362 terabytes (TB) of memory or 362,000 gigabytes of memory ; enough to load just about anything.
Storage is handled by traditional hard drives instead of SSDs, but don’t boo. The XT Jaguar has 10 petabytes of storage. What’s 10 petabytes ?—ten million gigabytes. At this point, people would usually say that that’s more than enough for anything, but even savvy computer users these days can figure out ways to utilize that kind of capacity.
The XT Jaguar has so much bandwidth and so much computing power that it can process a quadrillion mathematical calculations per second. Sustained memory bandwidth tops out at 578 terabytes per second and I/O bandwidth squeezes in 284 gigabytes per second.

The big question is, "Can it play Crysis?"
the answer being "no"
It still can't beat me at Toc-tac-toe
but its no WOPR, give me Joshua any day...lol
its nice to read the spec of the machine that will be used to spy on every phonecall and email sent.
"Can it play Crisis?"
It told me it doesn't feel like it wants to.......
Hmm..wonder what those people who persistantly bash AMD, have to say abou this.
Can it tell me just how someone like Obama managed to win the race for the Whitehouse? I'll put the kettle on..lol.
why did they choose AMD processors, does it have better price/perfomance ratio or better performance per watt
I believe the answer is yes.
Specifically, AMD processors are popular with server and super-computer operations because they offer low inter-core and memory latency, which are crucial to efficient operation within this field. On-die hardware and dedicated, high-speed interconnects make for a powerful, less complex and more energy-efficient solution overall when compared to the competition.
AMD has also just released the 'Shangha' core Opterons, which further refine performance and power efficiency and, best of all, are drop-in replacements hence minimal downtime.
As we all know it's different when dealing with desktop solution, where Intel's core 2 refinements are offering better overall performance, but this is a case where the shortcomings of those refinements are clear.
