The Sunway Taihulight (Chinese: 神威·太湖之光) is a Chinese supercomputer which, as of November 2016[update], is ranked number one in the TOP500 list as the fastest supercomputer in the world, with a LINPACK benchmark rating of 93 petaflops. This is nearly three times as fast as the previous holder of the record, the Tianhe-2, which ran at 34 petaflops. As of June 2016[update], it is also ranked as the fourth most energy-efficient supercomputer in TOP500, with an efficiency of 6,051.30 MFLOPS/W. It was designed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and is located at the National Supercomputing Center in Wuxi in the city of Wuxi, in Jiangsu province, China.
The Sunway TaihuLight uses a total of 40,960 Chinese-designed SW26010 manycore 64-bit RISC processors based on the Sunway architecture. Each processor chip contains 256 processing cores, and an additional four auxiliary cores for system management (also RISC cores, just more fully featured) for a total of 10,649,600 CPU cores across the entire system.
