The "Jaguar" in Tennessee, USA, has been crowned the fastest computer in the world and is to be used for science.

The new champion, consisting of 284 Cray supercomputer cabinets, will be able to crunch an amazing 1.64 Petaflops – 1,640,000,000,000,000 floating point operations per second. Tested so far up to 1.3 Petaflops, the team at Oak Ridge National Lab are hoping to crank the machine up to it’s full potential soon.

Specification:

45,000 Quad Core Opterons (AMD), 362 Terabytes of RAM (that’s 370,000 Gigabytes!), 10 Petabytes of storage (or 10,485,000 Gigabytes)

Performance:

578 Terabytes per second Memory bandwidth, 284 Gigabytes per second bus bandwidth (to move data around the system)

All in all an impressive machine which will knock the current champion, Roadrunner (at 1.34 Petaflops), off the top spot when it’s up to speed. Read The Register article, and also check out the top 500 supercomputers on Wikipedia (soon to be updated I’m sure!)
