BlueGene/L Breaks Another Speed Record

David Needle writes on

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.
