Official Operation Start Date and Time
Tuesday, July 1st, 2025, 14:00
Important Notes
Supercomputer and Application Server
– Public keys have not been transferred from the previous supercomputer system, so initial registration is required. However, users who registered during the trial operation period do not need to re-register.
– If the actual usage of storage exceeds the applied amount, new data cannot be written. In that case, please apply for additional services or delete unnecessary files as needed.
– The job scheduler has changed from the previous supercomputer, resulting in significant changes to job submission commands and job script formats. Please refer to the user guide available on the user portal for details on how to use the system.
Research Cloud
– Initial configuration of two-factor authentication is required. Please refer to the manual available on the user portal for details.
Other Information
Information regarding new user applications and additional service requests is summarized on this page.
If you wish to use the system or have not yet applied for additional services, please refer to the above and complete the necessary procedures.
2025.07.23Nextcloud introduced two-factor authentication (July 23 ~)
The cloud storage service (Nextcloud) introduced two-factor authentication (TOTP) of login for security enhancement after periodic maintenance on Wednesday, July 23, 2025.
The login process and the configuration of client applications have been modified from the previous methods due to the implementation of two-factor authentication. Please take note.
One-time password (authentication code) by Authenticator is required when logging in to Nextcloud
When you enter your ID/password at the first login, you will be required to register the Authenticator app, so please prepare the Authenticator app for your smartphone in advance.
* After logging in, please create backup codes and store them in a safe place in case the Authenticator becomes unavailable. You can generate the backup codes by clicking the “Generate backup codes” button in the security menu of the settings after logging in to Nextcloud.
Authentication with “App Password” is necessary for apps that are linked to Nextcloud
When you work with a client app or GakuNin RDM, you need to authenticate with an app password created by Nextcloud.
You can create the app password by clicking the “Create new app password” button in the security menu of the settings after logging in to Nextcloud.
* You can create multiple app passwords, and you can disable them individually from Nextcloud. If you share the same app password with multiple devices, you will need to reconfigure all of them in case of loss, theft, etc., therefore it is recommended to create and set it individually for each device.
2025.06.11New supercomputer system is ranked in TOP500
The new supercomputer system “Grand Chariot 2”, introduced in April 2025 and scheduled to begin full operation in July 2025, has been ranked 264th (27th in Japan) on the TOP500 list, which ranks the sites operating the 500 most powerful computer systems worldwide. The ranking was announced on June 10 (local time) during the “ISC High Performance 2025” conference held in Hamburg, Germany.
The performance result listed on the TOP500 was measured using only the GPU nodes of the system.
However, the system also includes the 480 CPU nodes, which support a wide range of applications, including those that were run on the previous system, “Grand Chariot”.
Together, the GPU and CPU nodes provide powerful and comprehensive computational resources.
For more information about Grand Chariot 2, please visit this page.
Applications for the use of Grand Chariot 2 are currently open.
If you are interested in using the system, please refer to here for details and consider applying.
