Press Release: K computer No. 1 in Three HPC Challenge Award Benchmarks


RIKEN, the University of Tsukuba, and Fujitsu today received top ranks in three of the four benchmarks at the 2012 HPC Challenge Awards or the performance of the K computer. The awards were announced on November 13 in Salt Lake City at SC12, the International Conference for High Performance Computing, Networking, Storage and Analysis. The first-place rankings were received in the following three benchmarks used for evaluating the all-around performance of a supercomputer: (1) Global HPL, which measures the floating point rate of execution for solving a linear system of equations; (2) STREAM, which measures sustainable memory bandwidth and the corresponding computation rate for simple vector kernels; and (3) FFT, which measures the floating point rate of execution of double precision complex one-dimensional Discrete Fourier Transform. With this, the K computer demonstrated, for the second consecutive year, high performance as a general-purpose supercomputer.
