A Chinese Supercomputer Was Ranked The World’s Fastest Machine

A Chinese supercomputer was ranked the world’s
fastest machine in the TOP500 list officially issued Tuesday by U.S. and
European researchers, highlighting China’s rapid progress in the field.

The Tianhe-1A system at the National Supercomputer Center in Tianjin,
is capable of sustaining computation at 2.57 petaflop/s, which equates
to a mind-numbing 2.57 quadrillions of calculations per second.

As a result, the former number one system — the U.S. Department of
Energy’s (DOE) Jaguar in Oak Ridge, Tennessee, that achieved 1.75
petaflop/s — is now ranked in second place, according to the 36th
edition of the TOP500 list.

The list is compiled by Hans Meuer of the University of Mannheim,
Germany, Erich Strohmaier and Horst Simon of National Energy Research
Scientific Computing Center (NERSC)/Lawrence Berkeley National
Laboratory, and Jack Dongarra of the University of Tennessee, Knoxville.

“A Chinese university made Tianhe based on China’s own technology,”
Dongarra said at a ceremony to honor the top 500 supercomputers Tuesday.
“Its interconnects are very interesting.”

Tianhe is a demonstration of how “a country can achieve if they put
their money on their ambitions,” said Strohmaier at the same ceremony.
“Making progress like that is only possible by supporting your research
community and your manufactures for extended period of time like five to
10 years.”

Liu Guangming, director of the National Supercomputer Center in
Tianjin, said Tianhe is a supercomputer system developed by the National
University of Defense Technology. It works as a backbone node of
Chinese National Grid.
