NASA Scales SGI Pleiades InfiniBand Cluster to 25,000 Intel Xeon Processor Cores
 

SGI, the trusted leader in technical computing, announced today that with over 60 miles of InfiniBand cabling in place at the NASA Advanced Supercomputing (NAS) Division at NASA Ames Research Center at Moffett Field, Calif., a scientist was able to utilize 25,000 SGI ICE Intel Xeon processor cores on Pleiades to run a space weather simulation.

One particular area of study is magnetic reconnection, a physical process in highly conducting plasmas such as those that occur in the Earth's magnetosphere, in which the magnetic topology is rearranged and magnetic energy converted to kinetic or thermal energy. This field of research is critical, as these disturbances can disable wide scale power grids, affect satellite transmissions and disrupt airline communications.
