[MGI30-01] Post-Fugaku Feasibility Study and Computational Astrophysics and Planetary Science

*Junichiro Makino1 (1.Kobe University)

Keywords:High-Performance Computing, large-scale simulations

Supercomputer Fugaku was completed in FY2020, and has already been used for three years. While it has achieved excellent results in the area of astrophysics and planetary science, problems have become apparent. MEXT has started a two-year "Feasibility Study on Next-Generation Supercomputing Infrastructures" in FY2022. The goal of this study is to clarify the needs of science, industry, and society on the performance and functions, and to propose options for a system that can realize these needs.

Two research teams were selected to study and propose actual systems: one team with RIKEN and the other team with Kobe University. The RIKEN team will work with multiple vendors to examine various possibilities. The Kobe University team will study the system configuration with accelerators, based on the accelerator for deep learning applications that is being developed jointly with PFN.

In this presentation, I would like to introduce the advantages and disadvantages of Fugaku, especially from the viewpoint of astrophysics and planetary science, the technical boundary conditions for post-Fugaku, and the status of the post-Fugaku feasibility study, focusing on the accelerator-based system being considered by the Kobe University team.
