Now the Fastest

The Tianhe-2 at China's National University of Defense Technology currently leads the Top500 list of the world's fastest supercomputers, the Associated Press reports. On the Linpack benchmark, the Tianhe-2 had a performance of 33.86 petaflops per second. It is comprised of 16,000 nodes, each of which includes two Intel Xeon IvyBridge processors and three Xeon Phi processors, a press release from Top500 adds.

Just behind the Tianhe-2 on the list, which comes out twice a year, is Titan at US Department of Energy's Oak Ridge National Laboratory and Sequoia at the DOE's Lawrence Livermore National Laboratory. Previously, Titan was ranked first, followed by Sequoia.
