Japan answers China’s supercomputing surge

A new supercomputer from Japan whose performance passed the 8 petaflop milestone ended China's brief period atop the list of the world's fastest supercomputers.

The Japanese system also set another all-time Top 500 record -- a 10 megawatt power rating while running the Linpack test used to determine system performance. Despite the significant power consumption, the K Computer achieved "extraordinarily high computing efficiency," said RIKEN and Fujitsu, in a statement.

The new Top 500 leader, the K Computer housed at the Riken Advanced Institute for Computational Science in Kobe, Japan, runs 68,544, eight-core Sparc chips made by Japan-based Fujitsu. The system is expected to eventually run some 80,000 of the Sparc processors. Read more...
