Schedule

Currently, we are scheduled to replace a current supercomputer system according to the schedule shown in the following table. We had been working hard to provide the trial environment around mid-December, however it has become difficult to start the trial operation in advance and we are forced to revise the schedule as below. We sincerely apologize for any inconvenience this may cause. We are preparing to provide the cloud system from mid to late November.

Trial Operation and Cloud System

• The trial operation and the cloud system will be available for users who used the system from April to July in 2022 with no additional usage fees.
• The number of nodes will be increased step by step through the trial operation to start the new system at the earliest.
• The cloud system will be configured to be used in the same way as the new system B/C.
  • The new system and the cloud system will use the same job scheduler.
  • File reference with NFS will be available for the new storage.
  • We are working to provide approximately 50 nodes.
  • We will announce the details later.

【Important Notice and Request】

• As a result of the procurement of the new system, the system will be delivered in two stages: the first configuration and the last configuration. It is difficult to provide a definite date for the system operation at this time, since the manufacturing schedule and the delivery date of the equipment have been delayed due to the global shortage of semiconductors. We are working hard to provide stable operation but we will operate the system with priority placed on the stable operation during the trial operation period from January to March 2023. We expect to install the last configuration, system A in June 2023 or later.
• Since the situation will result in lower computing performance than the current system until the new system A is installed, we would like to ask you to consider the use of supercomputers operated by other centers if necessary.
• Data migration has been completed, and data access will be resumed when we are ready to provide in early November. File access will be limited to read-only for the time being.

Call for application of the new system

The service will be provided with no additional application or usage fees during the trial operation period from January to March 2023 for users who used the system from April to July 2022 and have a valid supercomputer user number.

System Configurations

The new system is expected to consist of three types of systems based on the concept of a current system (System A, B and C), a new system equipped with an accelerator (System G), and a storage system.The CPU in systems A, B, and C are all Intel Xeon of the same generation, however there are differences in memory speed and capacity.System A is a configuration that emphasizes memory speed, System B is a configuration with a good balance between capacity and performance, and System C is a configuration that emphasizes memory capacity.

Camphor 3 (New System A, Successor to the Current System A) Scheduled to be released between around June and August, 2023

Laurel 3 (New System B, Successor to the Current System B) Scheduled to be released around January, 2023

Cinnamon 3(New System C, Successor to the Current System C) Scheduled to be released around January, 2023

Gardenia (New System G, a new system equipped with an accelerator) Scheduled to be released around January, 2023

Cloud System Scheduled to be released in late-November, 2022

Storage System Scheduled to be released in FY2022.

Flash Storage System Scheduled to be released in FY2023.

Software

New software stack is shown in the following table and basically offers equivalent compiler and libraries to the previous ones. We are sorry to inform you that we will no longer offer SAS due to difficulties in continuing to provide it.
