China's Tianhe-2 or MilkyWay-2 supercomputer surpassed the power of the US Titan to take over the top spot on
Top500.org's semi-annual list. Below is the top 10.
Milky Way
The Tianhe-2, also known as the MilkyWay-2, was named the "World's Fastest Supercomputer" by Top500.org, which updates its list biannually. The results are based on Linpack benchmarks, which measure supercomputers by the quadrillions of calculations per second.
China's National University of Defense Technology built the Tianhe-2, and also built the 10th-fastest supercomputer today, the Tianhe-1. That machine topped the world's fastest list in November 2010.
Milky Way-2 will be deployed at the National Supercomputer Center in Guangzhou, China, by the end of the year.
Here are the vital statistics from the Top500.org list of the fastest supercomputers:
