Japan : The most powerful computer in the world

Taking advantage of the conference held ISC’11 currently in Hamburg,Germany, the manufacturer and the Fujitsu Research Institute presented a Riken supercomputer they have co-developed.
With no less than 68 544 processors on board, the supercomputer known as K displays a phenomenal computing power of 8.162 petaflops, which corresponds to 8.162 million floating point operations per second.

That’s the equivalent of hooking up a million desktop computers. The Japanese machine actually uses half a million processors, said Professor Jack Dongarra of the University of Tennessee, a computer science professor who compiles the list with Hans Meuer of the University of Mannheim, Germany, and Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory.

Such clout allows it to raise Japan to first place in the TOP500, the global ranking of supercomputers. The rising sun was not reached since 2004, knowing that the classification has existed since 1993 and is updated twice a year in June and November.

“These computers help us drive innovation and industry, they help drive defense,” Dongarr said. “We’re going to be able to design better combustion engines, better reactors and we’ll be able to make more accurate predictions about the climate — every area of science today is touched by high-performance computing.”
