Chinese supercomputer to surpass Titan

Chinese supercomputer Tianhe-2 could be much faster it was prediceted. According to recent measurements in the standard Linpack benchmark, Tianhe-2 achieves 74 percent greater performance than current number 1 on the Top 500 list, American Titan.

Tianhe-2 in the 5-hour Linpack test achieved peak performance of 30.65 petaflops (Titan achieved 17.59) with slightly lower efficiency compared to U.S. rival - 1,935 versus 2,143 gigaflops per watt. Chinese supercomputer performance could be even greater given that the system achieved a result of working at 90 percent capacity, using 14,336 of the total 16,000 available computing nodes.

Tianhe-2 is still in development at the Chinese National University of Defense Technology (NUDT), and the final version of supercomputers will be placed in a computer center in Guangzhou. This hybrid supercomputer has 32,000 Intel Xeon processors (Ivy Bridge generation) and 48,000 Xeon Phi accelerator for a total of 3.12 million computing cores with 1.4 petabytes of RAM and 12.4 petabytes of storage. All of this is runing on Kylin Linux, while the theoretical peak performance is estimated at 54.9 petaflops. Announcement of the new list of the top 500 fastest supercomputers in the world is scheduled for 17th of this month.
