RIKEN is Japan's largest comprehensive research institution renowned for high-quality research in a diverse range of scientific disciplines. Founded in 1917 as a private research foundation in Tokyo, RIKEN has grown rapidly in size and scope, today encompassing a network of world-class research centers and institutes across Japan.
RIKEN has three major HPC systems: Fugaku, MDGRAPE-4, and HOKUSAI.
Fugaku is located at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan, is being developed under a national plan to design Japan’s next generation flagship supercomputer and to carry out a wide range of applications that will address high-priority social and scientific issues. It will be put to use in applications aimed at achieving the Society 5.0 plan, by running applications in areas such as drug discovery; personalized and preventive medicine; simulations of natural disasters; weather and climate forecasting; energy creation, storage, and use; development of clean energy; new material development; new design and production processes; and—as a purely scientific endeavor—elucidation of the fundamental laws and evolution of the universe. In addition, Fugaku is currently being used on an experimental basis for research on COVID-19, including on diagnostics, therapeutics, and simulations of the spread of the virus. The new supercomputer is scheduled to begin full operation in fiscal 2021 (which starts in April 2021).
MDGRAPE-4A, a special purpose computer for molecular dynamics simulations, was developed and is in operation by the laboratory for computational molecular design, RIKEN BDR in Osaka. An important application of the MDGRAPE-4A system is drug discovery study for diseases such as COVID-19, by simulating atomic interaction between viral proteins and drug molecules.
HOSKUSAI is operated by the Head Office for Information Systems and Cybersecurity (ISC). HOKUSAI consists of two systems: the supercomputer BigWaterfall (BW) and the data science platform SailingShip (SS). In BW, RIKEN researchers are able to perform highly parallel computations for a wide variety of calculations. In SS, we have just started to operate a private cloud environment with 30PB of storage to handle the data calculated in various experiments and simulations by RIKEN researchers. We also develop and operate data and meta-data management system for promoting open science.
