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:
Linpack performance (Rmax): 33,862.7 TFlop/s
Theoretical peak (Rpeak): 54,902.4 TFlop/s
Operating system: Kylin Linux

Cray built the Titan Cray XK7, which lost its title of fastest supercomputer and now resides in second place. It currently lives at the Oak Ridge National Laboratory.
Linpack performance (Rmax): 17,590.0 TFlop/s
Theoretical peak (Rpeak): 27,112.5 TFlop/s
Operating system: Cray Linux Environment

IBM built Sequoia, a BlueGene/Q supercomputer, which is operated by the US government at Livermore, California. Sequoia, another former leader, is now the third-fastest supercomputer.
Linpack performance (Rmax): 17,173.2 TFlop/s
Theoretical peak (Rpeak): 20,132.7 TFlop/s
Operating system: Linux
