Sandia’s Red Storm Is First Computer to Exceed 1 Terabyte per Second

`Global supercomputer leader Cray has announced that the “Red Storm” supercomputer installed at Sandia National Laboratories in New Mexico is the first computer to surpass the 1 terabyte-per-second (1 TB/sec) performance mark on a widely used test that measures communications among processors in high-performance computing (HPC) systems and provides a key indication of the total communication capacity of the network.

Red Storm posted 1.8 TB/sec (1.8 trillion bytes per second) on the PTRANS interconnect bandwidth test that is part of the High Performance Computing Challenge (HPCC) test suite. By comparison, this figure represents 40 times more communications power per teraflop (trillion floating point operations per second) than the PTRANS result posted by an IBM Blue Gene system that has more than 10 times as many processors.’
