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.
