Chinese supercomputer;World N:1

Chinese supercomputer Tianhe-2 rose to first place in the Top 500 world ranking, leaving far behind in fourth place, the Japanese champion "K", demotion motivates a hundredfold the Japanese to go head .Tianhe-2, of the Chinese University of Defense Technology, achieved computational performance of 33.86 petaflop / s (33.86 million billion operations per second), while the Japanese "K" (to pronounce Kei) peaked at 10.51 petaflop / s, ranked Top 500 Monday during a conference on supercomputing in Leipzig (Germany).Moreover, Tianhe-2 has reached this level two years before the target, said the agency responsible for setting the record.Behind Tianhe-2 arrived two Americans, Titan, who was first in the previous ranking, and Sequoia, which had taken the highest rank six months earlier (June 2012), while relegating "K" to second place."K" had been previously during the first year: he had taken the lead in June 2011 and was kept in the charts prepared in the following November."K" was then marked the spirits and strengthened the Japanese ego. It was indeed the first time since June 2004 that a Japanese supercomputer was the first. He had beaten flat-seams a Chinese rival (Tianhe-1A, 2.56 petaflops) and an American (Jaguar).This time it is the opposite and, hence, it tickles the Japanese, as shown in a reflection of a manager of the Japanese Ministry of Science, "it is only a performance speed", meaning there that, unlike the Chinese, Japanese, themselves, are concerned not only computing power but also of the electricity consumed, knowing that a supercomputer is a huge and very "energy" machine.The Japanese press also like to emphasize that Tianhe-2 is designed to calculate the trajectories of missiles and other military uses, while Japanese models are designed for simulations of natural disasters or development of new drugs.Still emulation that comes from regaining first place by the Chinese will push the Japanese into overdrive on future generations of supercomputers, with powers even multiplied.The TOP500 ranking, established in 1993, is updated twice a year, in June and November.
