Saturday September 02, 2006 ClearSpeed Breaks GFLOP per Watt Barrier
ClearSpeed, a producer coprocessor acceleration technology and Sun partner in HPC deals including Tokyo Tech, today announced Linpack benchmark results that set new standards for energy efficient computation for high performance computing (HPC) clusters.ClearSpeed Advance accelerator boards rated at only 25 Watts power consumption per board added 28.5 GigaFLOPS (GFLOPS) each to a cluster of Hewlett Packard Proliant DL380 G5 servers running the high performance Linpack benchmark. With two Advance accelerator boards in each of the four servers, the cluster performance was increased to over 364 GFLOPS while adding only 200 Watts to the overall power levels. Without ClearSpeed acceleration, the four node cluster delivered 136 GFLOPS from its 8 Intel(R) Xeon(R) 5160 (Woodcrest) dual core processors while consuming 1,940 Watts of power. A similarly configured single node delivered 90 GFLOPS compared with 34 GFLOPS for the non-accelerated system.
The ClearSpeed accelerated cluster completed the Linpack benchmark run in just 18.4 minutes while using only 40% of the energy required by the non-accelerated cluster which took 48.4 minutes to finish.
