For details on software for research, see Software Licences for Research (from within RIKEN only).

Related systems

The HOKUSAI shared-use computers consist of the supercomputer HOKUSAI BigWaterfall2 (HBW2) and the data science platform HOKUSAI SailingShip (HSS).
For those wishing to use GPUs for AI-related research, see also RAIDEN, a large computer for deep learning analysis (only from within RIKEN) owned by the Research Centre for Innovative Intelligence and Integration.

2. HBW2 Use Categories

The total computing resources of MPC for FY2024 are as follows

MPC 301,916 Kilo-core hours
1. RIKEN Project
  • Available only to those within RIKEN
  • A free allocation is available for each project (1% of MPC’s total annual computation time).
    • If you start in the middle of the fiscal year, the amount is proportional to the remaining time.
  • Additional core hours can be added for a usage fee.
  • If core hours are used up, the project will be given a lower priority, but can be executed free of charge.
  • HBW2 Subsystem (Large memory/GPU/FPGA servers) are available.
2. HPCI Project
  • Available to people inside and outside RIKEN
  • Apply once a year via the HPCI application system (application period is around September-October of the previous year)
  • Free of charge and available on a large scale
  • For HPCI project, see About HPCI Project.
Storage use
  • Home area (/home)
    • 4 TB per HBW2 account free of charge and cannot be increased
  • Data area (/data)
    • Available per project, apply for RIKEN projects via the HBW2 portal
Usage fees

HBW2 is available free of charge to RIKEN researchers to a certain degree.
For more information on the usage fees, see Usage Fee of HOKUSAI HBW2.

4.Application for use of RIKEN Project

HBW2 Portal

Various applications and confirmations can be made via the HBW2 Portal.

Types of account etc. in HBW2
  • HBW2 Portal users
    • Required to become an project member of HBW2
    • Created by entering user information when logging in to the HBW2 Portal for the first time
    • You can apply for new projects, and can make various applications and information related to your projects
  • HBW2 account
    • Linux account required to use HBW2 computing resources.
    • Created when you become an project member for the first time.
    • Log in to the HBW2 front-end server by registering your ssh public key at the HBW2 Portal.
Flow of use for RIKEN project
  1. All project members log in to the HBW2 Portal and register the HBW2 Portal users.
  2. Apply for a new project on the HBW2 Portal
    • If there are non-residents, a security export control review is required as soon as they are ready.
    • Notification of creating a new project and HBW2 accounts within a few days if there are no problems.
  3. Each project member registers their ssh public key on the HBW2 Portal.
  4. Login to the HBW2 front-end server using ssh
Log in to the HBW2 portal
  • Log in using the Integrated Authentication infrastructure (Shibboleth authentication)
    • Available to all RIKEN members, including Visiting Scientists.
  • If you do not know your password for the Integrated Authentication Infrastructure (Shibboleth authentication), you can change the password according to the “How to reset Okta” in Okta/Shibboleth (Single Sign-On/MFA)
HBW data
  • Access to backup data in the home area (/home) and data area (/data) of HBW is available until the trial operation.
  • Access to hierarchical storage (/arc) is scheduled until FY2024.
    • Future operation of the tape device is under consideration.

5. User responsibility

Security Export Control

If there are non-residents or specific categories of non-residents in the RIKEN project members, a review form must be drafted and approved by the Research Integrity and Economic Security Division.
When you submit a new RIKEN project application, please have it reviewed at that time.
If you have already used an HBW2 trial project and have not had your review form approved, please have it reviewed at this time.

If you have any questions about the review process, please contact the Security Export Control Officer (anzenhosyo [at] riken.jp) of the Research Integrity and Economic Security Division.
Please note that if you are not familiar with security export control, please consult with your laboratory assistant or someone else who is familiar with the subject.
The web page of the Research Integrity and Economic Security Division on security export control(from within RIKEN only).
