The fastest computer in 2013....it done by chinese

China builds fastest supercomputer in the world

The Tianhe-2 supercomputer from China is slated to become the fastest in the world.
China appears to have once again taken the lead from the United States in the burgeoning supercomputing wars, developing a supercomputer that is twice as fast as anything America has to offer.

The new Tianhe-2 supercomputer, nicknamed the Milkyway-2, was unveiled by China's National University of Defense Technology (NUDT) during a conference held in late May. University of Tennessee professor Jack Dongarra confirmed this week that the Milkyway-2 operates as fast as 30.7 petaflops -- quadrillions of calculations -- per second.
