The Sunway TaihuLight supercomputer is the world’s first system with a peak performance greater than 100 PFlops, and a parallel scale of over 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 utilizing the computing resource of over 10 million cores for traditional scientific simulation applications, as well as data analytic applications. 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.


Dr. Haohuan Fu is an associate professor in the Ministry of Education Key Laboratory for Earth System Modeling and Center of Earth System Science in Tsinghua University. He is also the associate director of the National Supercomputing Center in Wuxi. His research interests include design methodologies for highly efficient and highly scalable simulation applications that can take advantage of emerging, multi-core, many-core, and reconfigurable architectures, and make full unitlisation of current Peta-Flops and future Exa-Flops supercomputers; and intelligent data management, analysis, and data mining platforms that combine sustainable methods and machine learning technologies.
