The awards were announced on Nov 15 at SC11, the International Conference for High Performance Computing, Networking, Storage and Analysis taking place in Seattle.

The first-place rankings in the HPC Challenge Awards were received in the following four benchmarks used for evaluating the all-around performance of a supercomputer: 1) Global HPL; 2) Global RandomAccess; 3) EP STREAM (Triad) per system; and 4) Global FFT.

RIKEN said the HPC Challenge Awards demonstrate that, in addition to achieving successive top-place rankings on the June and November 2011 editions of the TOP500 list measuring LINPACK computational speed, the K computer is evaluated very highly in all-around performance as a general-purpose supercomputer.

The K computer is currently under joint development by RIKEN and Fujitsu.
