TaihuLight

TaihuLight, officially Sunway TaihuLight, is a Chinese supercomputer located at the National Supercomputing Center in Wuxi, Jiangsu Province. It was designed and built by the National Research Center of Parallel Computer Engineering and Technology and became operational in 2016. In the 2016 TOP500 list it was named the world's fastest, achieving a sustained performance of about 125 petaflops on the LINPACK benchmark, a figure that established a new benchmark for petascale computing. The system's peak theoretical performance is higher, but LINPACK performance is the standard measure used for rankings.

Hardware and architecture: TaihuLight employs the Sunway SW26010 many-core processors, each containing 260 computing cores. The

Impact and status: TaihuLight demonstrated the viability of extensive many-core designs for high-performance computing and signaled
