BlueGene/L Breaks Another Speed Record

David Needle writes on internetnews.com:

The Department of Energy's National Nuclear Security Administration (NNSA) and IBM today announced the world's fastest supercomputer has outdone itself. In its latest testing, IBM said its BlueGene/L (BG/L) achieved a sustained performance of 207.3 trillion floating-point operations per second (teraFLOPS), a new record for floating-point performance.

IBM said its software researchers were able to improve performance with new mathematical libraries that take better advantage of the dual-core architecture of the floating point unit of the PowerPC 440 processor used in Blue-Gene/L. A year ago, BG/L's floating point performance was less than 100 teraFLOPS.
