Cray unveiled its Cascade supercomputer architecture, one of the first to support Intel's upcoming Xeon Phi accelerators.
While the system has been officially launched only now, Cray has been selling these systems as early as 2010 and claims to have to have six Cascade supercomputers under contract valued at more than $100 million already.
Next to IBM's BlueGene/Q design, Cascade is the second major architecture that is claimed to scale to about 100 petaflops. The system, which carries the commercial name XC30, will run Intel's Xeon E5-2600 series processors and can, in theory, support more than 1 million cores, Cray said. Future versions of the XC architecture will also be available with Intel Xeon Phi coprocessors and Nvidia Tesla GPUs to enhance the system's floating point horsepower.
According to Cray, the XC30 can ship with up to 384 Xeon E5-2600 processors per cabinet, representing up to 3,072 cores and an initial peak performance of 66 TFlops per cabinet. There can be 32 to 128 GB of memory per node, and a memory bandwidth of up to 117 GB/s. A single fully equipped (liquid cooled) cabinet will weigh 3,450 lbs and require power supply of about 88 KW, Cray said.
