Chinese Exascale Sunway Supercomputer has Over 40 Million Cores, 5 ExaFLOPS Mixed-Precision Performance
The Exascale supercomputer arms race is making everyone invest their resources into trying to achieve the number one spot. Some countries, like China, actively participate in the race with little proof of their work, leaving the high-performance computing (HPC) community wondering about Chinese efforts on exascale systems. Today, we have some information regarding the next-generation Sunway system, which is supposed to be China's first exascale supercomputer. Replacing the Sunway TaihuLight, the next-generation Sunway will reportedly boast over 40 million cores in its system. The information comes from an upcoming presentation for Supercomputing 2023 show in Denver, happening from November 12 to November 17.
The presentation talks about 5 ExaFLOPS in the HPL-MxP benchmark with linear scalability on the 40-million-core Sunway supercomputer. The HPL-MxP benchmark is a mixed precision HPC benchmark made to test the system's capability in regular HPC workloads that require 64-bit precision and AI workloads that require 32-bit precision. Supposedly, the next-generation Sunway system can output 5 ExaFLOPS with linear scaling on its 40-million-core system. What are those cores? We are not sure. The last-generation Sunway TaihuLight used SW26010 manycore 64-bit RISC processors based on the Sunway architecture, each with 260 cores. There were 40,960 SW26010 CPUs in the system for a total of 10,649,600 cores, which means that the next-generation Sunway system is more than four times more powerful from a core-count perspective. We expect some uArch and semiconductor node improvements as well.
