Summary

A research group of University of Tsukuba, RIKEN, and Tokyo Institute of Technology announced that the ACM Gordon Bell Prize was awarded to that group for the large scale parallel simulation using the "K computer" at SC12, the International Conference for High Performance Computing, Networking, Storage and Analysis held in Salt Lake City, on November 15 (US Pacific Standard Time). The group performed extremely large simulations with an unprecedentedly high level of efficiency.

The target of the award-winning simulation, presented at SC12, were the gravitational evolution of dark matter in the early Universe. The number of dark matter particles simulated was two trillions, which is the world's largest dark matter simulation at present. The execution performance was 5.67 Pflops on ...
