Chinese Supercomputer Named The World's Fastest

Chinese Supercomputer Named The World's Fastest 












A Chinese supercomputer "Tianhe-2" is declared as the fastest in the world, according to survey results announced by Monday, comfortably overtaking a US machine which now ranks second.

 China's National University of Defense Technology, has built the world's fastest supercomputer, almost doubling the speed of the U.S. super computer that previously claimed the top spot and underlining China's rise as a science and technology powerhouse.

Tianhe-2, a supercomputer build by a chines university, achieved processing speeds of 33.86 petaflops per second.That's the equivalent of 33,860 trillion calculations per second on a benchmarking test, overtaking the number one spot in the semiannual TOP500 listing of the world's fastest supercomputers released this Monday.

The benchmark tests show the machine is by far the fastest computer ever constructed, achieved the processing speed of 33.86 petaflops. Its main rival, the US-designed Titan, had achieved the processing speed of 17.59 petaflops per second, the survey's website said.

The Tianhe-2, which means Milky Way-2, knocks the U.S. Energy Department's Titan machine off the No. 1 spot,  which eventually be the return of title to china.The Tianhe-1 was ranked the world's fastest in November 2010, only to be overtaken by a machine from the US.

Most of the Tianhe-2's processors, parts and features of the system are developed in China..the operating system, front-end processors, software and the interconnection are mainly Chinese except for its main processors, which are designed by US firm Intel.

Supercomputers are used for complex calculations such as simulating nuclear explosions, designing jetliners and modeling weather systems.

But the US still dominates the overall supercomputer numbers and rankings, with 252 systems making the top 500. The number of European machines are 112 systems remains lower than the number of Asian machines are 119.

List of  Top 500 supercomputers is produced twice a year, are rated based on speed and the performance in a benchmark test by experts from Germany and the United States.
