Abstract
This paper reports Linpack benchmark evaluation on the TSUBAME supercomputer, a large scale hybrid supercomputer equipped with graphics processing units (GPUs) and ClearSpeed SIMD accelerators. With all of about 10,000 Opteron cores, 640 Xeon cores, 648 ClearSpeed accelerators and 624 NVIDIA Tesla GPUs, we have achieved 87 TFlops. This paper also describes our design policy and tuning method that take characteristics of accelerators into account, which are essential to achieve scalability on hybrid supercomputers. The design is significantly different from that of LANL RoadRunner, a hybrid system equipped with Cell processors. We discuss the difference from the viewpoint of system architecture.
