China's Tianhe-2 Heads Static List of 10 Fastest Supercomputers

In the current world of supercomputers, the more things change, the more they stay the same. For the fifth consecutive time, China's massive Tianhe-2 (also known as Milky Way-2) system topped the Top500 list of the world's fastest supercomputers, essentially doubling the performance capabilities of Titan, a U.S.-based system that came in second. In fact, the roster of the top 10 fastest systems looks familiar, with only one new system—Shaheen II, at the King Abdullah University of Science and Technology in Saudi Arabia—breaking into the ranks since the twice-yearly list was last released in November 2014. The organizers of the Top500 list—released July 13 at the International Supercomputing Conference in Germany—noted several trends within the high-performance computing space. While the total combined performance of all 500 systems on the list grew from 309 petaflops in November to 361 petaflops, it was a slowdown from the growth seen in previous long-term trends. In addition, outside of Shaheen II, the other systems in the top 10 were installed in either 2011 or 2012, continuing a slowing trend in turnover among the top systems that began in 2008, organizers said.
