Japan’s "K Computer" remained on top of the world’s top 500 list of supercomputers, although the top ten remained unchanged from June.
Instead, the notable element of the "K" computer was the fact that it reached 10 petaflops, or ten quadrillion floating-point operations per second – the first time the 10 Pflop mark had been broken.
The K Computer is installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan. It achieved an impressive 10.51 Petaflop/s on the Linpack benchmark using 705,024 SPARC64 processing cores. Aside from performance increases by the individual machines, however, the rankings remained the same.
