The Shared Use Computers HOKUSAI consists of the Supercomputer HOKUSAI BigWaterfall (HBW) and the Data Science Infrastructure HOKUSAI SailingShip (HSS).
HBW provide high performance and highly parallel computing environment/shared storage/network.

1. Supercomputer HOKUSAI BigWaterfall(HBW) system

Introduction

RIKEN is Japan’s largest comprehensive research institution renowned for high-quality research in a diverse range of scientific disciplines. The purpose of the supercomputer system is to contribute to scientific and technological research consistent with RIKEN’s mission.

RIKEN do not charge fees for basic usage the RIKEN Supercomputer System. This is because we want to provide computation environment as free and comfortable as possible to RIKEN researchers and help them obtain better research results. From October 2020, however, a usage fee has been introduced for some special use of supercomputers

You are strongly requested to read the Supercomputer System Usage Policy and Supercomputer Systems Operation Procedure before you make applications.

System Overview

Here is a HOKUSAI System Overview(Updated: June. 4, 2020), which is a overview of hardware and software of HOKUASI BigWaterfall(HBW).
See more here about the software for research.

If you are interested in using a GPU for AI-related research, please refer to RAIDEN, a large-scale computer for deep learning analysis (only from within RIKEN) owned by the the RIKEN Center for Advanced Intelligence Project.
