K Computer High Performance Computing Challenge Award

Here is an interesting article

RIKEN, the University of Tsukuba and Fujitsu today announced that they received top ranks in two of the four benchmarks at the 2014 HPC Challenge Class 1 Awards, which evaluate the overall performance of supercomputers, for the performance of the K computer. The first-place rankings were received in two benchmarks: (1) Global HPL, which measures the floating point rate of execution for solving a linear system of equations; and (2) EP STREAM (Triad) per system, which measures sustainable memory bandwidth and the corresponding computation rate for simple vector kernels. This marks the fourth consecutive year, from 2011 to 2014, that the K computer has ranked first in the HPC Challenge Class 1 Awards.
