China trounces US in TOP500 supercomputer race |
June 17, 2013
The supercomputing arms race is heating up again between the United States and China, as China retakes the top spot in the 41st Top500 listing of the world's most powerful supercomputers with Tianhe-2, an updated system that was able to execute 33.86 petaflops, or 33.86 thousand trillion floating point operations per second.Tianhe-2 churned out almost twice as many petaflops as the second computer on the list, Titan, a Cray XK7 system installed at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory. The top system in the previous Top500 competition, compiled in November, Titan clocked 17.59 petaflops on the Linpack benchmark for this round of the Top500.The appearance of Tianhe-2 came as something of a surprise, even as word about its immense capabilities leaked out on the Internet earlier this month. The system was not expected to be operational for another two years.China's National University of Defense Technology built Tianhe-2, or Milky Way-2, with 16,000 nodes. Each node runs two Intel Xeon IvyBridge processors and three Xeon Phi processors, for a combined total of 3.12 million computing cores. The system, located at the National Supercomputer Center in Guangzho, China, will be fully operational by the end of the year.To read this article in full or to leave a comment, please click here
