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.

A Japanese supercomputer has become the fastest in the world, making calculations more than three times faster than a Chinese rival, its developers said Monday.The c has achieved 8.162 quadrillion calculations per second, or 8.162 petaflops in computer jargon, according to developers Fujitsu Ltd. and the state-funded Institute of Physical and Chemical Research, known as RIKEN.In doing so K Computer overtook Chinas Tianhe-1A of the National Supercomputing Centre in Tianjin, which became the world number-one in November and is capable of operating at 2.566 petaflops.

The Tokyo Institute of Technology said Wednesday it will commence in November the full-fledged operation of Tsubame 2.0, which would become Japan’s fastest supercomputer.
The computer can calculate 2,400 trillion times per second, or 12 times faster than a supercomputer at the Japan Atomic Energy Agency, which is currently the fastest in the country.
Tsubame 2.0, however, is expected to be overtaken once Riken, a comprehensive research institute for natural sciences, starts operating a next-generation supercomputer in 2012. The Riken supercomputer project had faced suspension under a decision by the waste-cutting panel of the government led by the Democratic Party of Japan but was later allotted a budget to continue development.
