RIKEN Center for Computational Science (R-CCS) Kobe, Japan
We have been carrying out the FLAGSHIP 2020 to develop the Japanese next-generation flagship supercomputer, Post-K, named “Fugaku”. In the project, we have designed a new Arm-SVE enabled processor, called A64FX, as well as the system, including interconnect, with the industry partner, Fujitsu. The processor is designed for energy-efficiency and sustained application performance. The Fugaku system was delivered, and is now partially used for early access users. In this talk, I will report on the performance results of Fugaku and the A64FX manycore processor for several benchmarks as well as its architecture overview.
