Cray Day! Make way for the PetaScale Jaguar

Where's Seymor?

It is an upgrade. But way up. How about a quadrillion mathematical calculations per second? Sounds prettier  than ‘1.64 petaflops, n’cest pa?  Yes, the folks at Oak Ridge have a hot-rod CPU. The makers call it Jaguar and mark it the world’s first petaflop system dedicated to open research. So apparently there’s more flops in the dark.

 

The upgrade at DOE’s Oak Ridge National Leadership Computing Facility represents a major milestone in a four-year project, begun in 2004 when DOE’s Office of Science launched a sustained effort to upgrade supercomputing capabilities for unclassified research at DOE’s complex of national laboratories.

Jaguar uses over 45,000 quad-core Opteron processors and features 362 terabytes of memory and a 10-petabyte file system. The machine has 578 terabytes per second of memory bandwidth and input/output (I/O) bandwidth of 284 gigabytes per second. 

Cray is on the move on other fronts as well. They have just announced  availability of NVIDIA Tesla C1060 GPU Computing processors in the new Cray CX1 line. Fits into a regular office without humongous refrigeration. Each Tesla processor has hundreds of processor cores that deliver nearly one teraflop of peak computing performance, we are told. It’s the revenge of the GPUs, one hopes.
