A64FX: 52-Core Processor Designed for the 442PetaFLOPS Supercomputer Fugaku

Abstract

In supercomputing, high-performance computing (HPC) applications require large amounts of parallel-processing capability and high memory bandwidth. Recently, artificial intelligence (AI) applications, which have characteristics similar to HPC applications, have played an important role in supercomputers. The supercomputer Fugaku [1] has a large number of general-purpose processors for a high-performance, high-density, and high-reliability implementation, as well as low power consumption to realize a massively parallel system for multiple applications targeting HPC and AI.
