Cray Takes Supercomputing Lead

Cray has taken the supercomputing lead by beating IBM's Roadrunner with it's XT Jaguar. The Jaguar, which came in fifth worldwide in the last set of TOP500 supercomputer rankings, is expected to top the chart when the new rankings are announced on November 17th.

Here are the official specs.

Jaguar uses over 45,000 of the latest quad-core Opteron processors from AMD and features 362 terabytes of memory and a 10-petabyte file system. The machine has 578 terabytes per second of memory bandwidth and unprecedented input/output (I/O) bandwidth of 284 gigabytes per second to tackle the biggest bottleneck in leading-edge systems—moving data into and out of processors. The upgraded Jaguar will undergo rigorous acceptance testing in late December before transitioning to production in early 2009.
