The Sunway TaihuLight (Chinese: 神威·太湖之光 Shénwēi·tàihú zhī guāng) is a Chinese supercomputer which, as of November 2023[update], is ranked 11th in the TOP500 list,[1] with a LINPACK benchmark rating of 93 petaflops.[2] The name is translated as divine power, the light of Taihu Lake.[3] This is nearly three times as fast as the previous Tianhe-2, which ran at 34 petaflops. As of June 2017[update], it is ranked as the 16th most energy-efficient supercomputer in the Green500,[4] with an efficiency of 6.1 GFlops/watt. 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.[5][2]
The Sunway TaihuLight was the world's fastest supercomputer for two years, from June 2016 to June 2018, according to the TOP500 lists. The record was surpassed in June 2018 by IBM's Summit.[6][5][7]
