China’s Sunway TaihuLight tops world supercomputer ratings

Chinese supercomputers maintained their No. 1 ranking on the 47th edition of the TOP 500 list of the world’s top supercomputers. The new Sunway TaihuLight supercomputer operates at 93 petaflop/s (quadrillions of calculations per second) Rmax on the LINPACK benchmark — twice as fast and three times as efficient as China’s Tianhe-2 (at 33.86 petaflop/s), now in the #2 spot.

The new supercomputer was developed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi in China’s Jiangsu province. The complete system has a theoretical peak performance of 125.4 Pflop/s, with 10,649,600 cores and 1.31 PB of primary memory.
