Sunway TaihuLight: Designing and Tuning Scientific Applications at the Scale of 10-Million Cores

Speaker: Dr Haohuan Fu is Deputy Director of the National Supercomputing Center in Wuxi, China, and leads the research and development efforts on Sunway TaihuLight, the current fastest supercomputer in the world.

Abstract:
The Sunway TaihuLight supercomputer is the world's first system with a peak performance greater than 100 PFlops, and a parallel scale of more than 10 million cores.

In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators (NVIDIA GPU or Intel MIC), the computing power of TaihuLight is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements (MPEs) and computing processing elements (CPEs) in one chip.

This talk will report our most recent progress on utilising the computing resource of more than 10 million cores for traditional scientific simulation applications, such as climate modelling, earthquake simulation, n-body, CFD, and big data analytic applications, such as remote sensing data processing, and Sunway-based deep-learning framework. Based on that, we will try to provide a picture of the major challenges as we see when mapping either new algorithms or existing softwares onto the Sunway TaihuLight supercomputer, and the major advantages brought by this machine.
