China running first >100-PFlop supercomputer

The Sunway TaihuLight supercomputer is the first system in the world that has a peak performance of more than 100 PFlops. Developed entirely in China, it is operated by the National Supercomputing Center in Wuxi (NSCC-Wuxi). As the world’s fastest supercomputer, it contributes to research fields such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation.

Three of the applications have managed to scale to the full system, and have been nominated as the finalists for the Gordon Bell award of 2016—the highest honor in the domain of high performance computing applications.

The peak performance of the Sunway TaihuLight is 125 Pflops, the Linpack performance is 93 PFlops, and the performance per Watt is 6.05 GFlops/W.

One major technology innovation of the Sunway TaihuLight supercomputer is the homegrown SW26010 many-core processor, which includes 4 management processing elements (MPEs) and 256 computing processing elements (CPEs), and provides a peak performance over 3.06 TFlops.

The Sunway TaihuLight has already provided computational support to research universities and institutes in China, such as Tsinghua University, Beijing Normal University, Chinese Academy of Sciences, and the First Institute of Oceanography.
