Cray Red Storm


Red StormRed Storm is a new Massively Parallel Processor (MPP) computer designed to scale from a single cabinet and relatively few processors to hundreds of cabinets and thousands of processors. The system uses high production volume commodity processors combined with a very high performance 3-D mesh interconnect to produce high parallel efficiency on a broad spectrum of scientific and engineering applications and has an excellent price/performance ratio.

Red Storm was developed jointly by Cray Inc., and the Department of Energy's (DOE) National Nuclear Security Administration's (NNSA) Sandia National Laboratories. It was installed at Sandia National Laboratories in Albuquerque, NM, in the winter of 2004.

The installation at Sandia operates in a dual network—classified (Red) and unclassified (Black)—configuration. The machine can be rapidly reconfigured to make all the compute nodes classified, all the compute nodes unclassified, or, in normal operation, three-quarters of the compute nodes available to either of the two networks and one-quarter of the machine available to the other network.
