講演要旨: 詳細を見る

RIKEN R-CCS and Fujitsu are developing Post-K, successor of K computer, that will be available for early access program in Q2 of 2020 and will begin general operation in 2021. Fujitsu recently announced the specification of CPU, named A64FX, and its interconect, TofuD, for Post-K. A64FX is the first implementation of Arm 64bit HPC architecture (Scalable Vector Extension) and TofuD is an enhanced version of Tofu used in K computer. The system software developed in the post K supercomputer includes a novel operating system for general-purpose manycore architectures, low-level communication and MPI libraries, and file I/O middleware. In this presentation, after inroducing an overview of Post-K hardware and system software, future research directions will be addressed.
