A64FX

It was recently announced that the Fugaku supercomputer, located at Riken in Japan, has scored the #1 position on the TOP500 supercomputer list, as well as #1 positions in a number of key supercomputer benchmarks. At the heart of Fugaku isn’t any standard x86 processor, but one based on Arm – specifically, the A64FX 48+4-core processor, which uses Arm’s Scalable Vector Extensions (SVE) to enable high-throughput FP64 compute. At 435 PetaFLOPs and 7.3 million cores, Fugaku beat the former #1 system by 2.8x in performance. Currently Fugaku has been used for COVID-19 related research, such as modelling tracking rates or virus in liquid droplet dispersion. The Fujitsu A64FX card is a unique piece of kit, offering 48 compute cores and 4 control cores, each with...
