China has overtaken the United States with the construction of the world's fastest supercomputer. The Tianhe-2, whose name translates to "Milky Way," is almost twice as fast as the previous U.S. record holder . with speeds equivalent to more than an astonishing 338 million normal PCs.

LOS ANGELES, CA (Catholic Online) - Developed by the National University of Defense Technology in China's Changsha city. The Tianhe-2 is capable of sustained computing of 33.86 petaflops per second, the equivalent of 33,860 trillion calculations per second, with the average everyday computer performing around 100 million per second.

The most recent results were published in the TOP500 report, an official bi-annual listing of the world's faster supercomputers.

1. Tianhe-2 - China
2. Titan - U.S.
3. Sequoia - U.S.
4. K computer - Japan
5. Mira - U.S.
6. Stampede - U.S.
7. Juqueen - Germany
8. Vulcan - U.S.
9. SuperMuc - Germany
10. Tianhe-1A - China


According to this list, the U.S, dominates the top ten with computers in second, third, fifth, sixth and eighth place. Japan's K computer is in fourth spot, while Germany's Juqueen and SuperMuc are in seventh and ninth place, while Tianhe-2's predecessor, Tianhe-1A, is tenth.

The Tianhe-1A came in first in November 2010. Japan's K computer overtook in 2011.

Each computer on the list was tested against the Linpack benchmark, which is used as a "yardstick of performance" and was chosen because it is widely used across all relevant systems.

The Chinese said it intends to install the Tianhe-2 equipment at the National Supercomputer Center in Guangzhou, China where it will be used for "research and education." Supercomputers such as the Tianhe-2 are used for simulating nuclear explosions and designing jetliners.

The Tianhe-2 knocked the U.S. Department of Energy's Titan machine off the number one spot, which only achieved 17.59 petaflops per second.

The Chinese government sponsored the project and doesn't expect the computer to be fully functional until 2015.

"Most of the features of the system were developed in China, and they are only using Intel for the main compute part," TOP500 editor Jack Dongarra says.
