China builds world's fastest supercomputer
Beijing: Chinese scientists have once again built the world's fastest supercomputer, capable of performing 33.86 quadrillion operations per second, surpassing the U.S. Titan supercomputer.
The Tianhe-2, or Milkyway-2, has a peak performance speed of 54.9 quadrillion operations per second, according to the National University of Defense Technology (NUDT), which built the computer.
This is the second time China has made it to the first place in the Top 500 list of the world's most powerful supercomputers. Tianhe-2's predecessor, Tianhe-1A, was the world's fastest supercomputer from November 2010 to June 2011, when it was surpassed by Japan's K computer.
Matching home-grown Feiteng-1500 CPUs as well as Intel Xeon and Xeon Phi processors, Tianhe-2 was almost twice as fast as the second computer, Titan, which is capable of running at 17.6 quadrillion operations per second.
