China's supercomputer world's fastest
CHINA: A Chinese supercomputer is the fastest in the world, according
to survey results announced Monday, comfortably overtaking a US machine
which now ranks second.
Tianhe-2, a supercomputer developed by China's National University of
Defense Technology, achieved processing speeds of 33.86 petaflops (1000
trillion calculations) per second on a benchmarking test, earning it the
number one spot in the Top 500 survey of supercomputers.
The tests show the machine is by far the fastest computer ever
constructed. Its main rival, the US-designed Titan, had achieved a
performance of 17.59 petaflops per second, the survey's website said.
Five of the world's 10 fastest computers are installed in the US, the
survey said, with the two in China, two in Germany and one in Japan.
The recognition of Tianhe-2, meaning Milky Way-2, as the world's
fastest computer marks the return of the title to China after the
machine's predecessor, the Tianhe-1 was ranked the world's fastest in
November 2010, only to be overtaken by a machine from the US.
Unlike some of its Chinese predecessors, most of the Tianhe-2's parts
are developed in China, except for its main processors, which are
designed by US firm Intel.
