Announcement about exemption from the usage fee for the Data Science Infrastructure as a power-saving measure

Exemption from the usage fee for the Data Science Infrastructure as a power-saving measure

In order to save electricity throughout RIKEN, we promote the migration of computing resources such as computers and storage space currently in use at each laboratory to the Data Science Infrastructure HOKUSAI SailingShip (SS). To promote the migration, the SS usage fee for the migration will be exempted.

Subject
  • Servers and storage currently in use at all RIKEN sites to be migrated to SS between December 2022 and February 2023.
    • The migration period shall be the minimum necessary and in principle within one month.
  • Only those in use with the power on will be considered, not including notebook PCs.
    • Those that are turned off for power-saving measures, will be included in the scope.
Computing Resources for Exempting Usage Fees
  • From the start of the migration to the end of March 2024, the usage fees will be exempted.
  • In principle, 2 vCPU per physical core of the CPU of the computing resource to be migrated will be exempted.
    • The upper limit per laboratory is 10 SS nodes (920 vCPU).
  • The usage fee will be waived for the effective capacity of the storage space to be migrated.
    • The upper limit per laboratory is 100 TB.
Application Procedure
  1. Send an email to E-mail: with the application details shown below.
    • Receive acceptance and guidance
  2. Migration work to SS
    • Project creation at SS
    • System construction at SS
    • Data migration to SS
    • Contact us after the migration is completed
  3. Confirmation of termination of use of computing resources
    • On-site confirmation by Information Systems Division
Application Details
  1. Applicant name
  2. Payment representative
    • Must be the same as the payment representative of the SS project.
    • Permission must be obtained in advance and included in the CC of the application email.
  3. Affiliation of the payment representative
    • Center name, laboratory name, etc.
  4. Computing resources to be turned off after the migration
    • Overview of Computing Resource Usage
    • Total number of cores of servers
      • Breakdown for each computing machine, including CPU type
    • Effective capacity of storage
  5. Migration period
    • In principle, within 1 month.
    • If your system has a certain size and you are uncertain about the feasibility of the migration, please contact us.
      • Describe your system and your concerns about the transition.
Example of Application
  1. Applicant name: Taro Riken
  2. Payment representative: Jiro Wako
  3. Affiliation of the payment representative: XX center XX laboratory
  4. Computing resources to be turned off after the migration
    Overview of Computing Resource Usage: For storage and analysis of XX experimental data
    Total number of cores of servers: 360 core
    1 login node: Intel Xeon Gold 6148 (20 cores) x 2 CPUs
    8 compute nodes: Intel Xeon Gold 6148(20 cores) x 2 CPUs
    Storage effective capacity: 10 TB(NetApp EXXXX 2 nodes)

  5. Migration period: December 21 – January 20
Others
  • SS Usage Information
  • Support for PIaaS usage in SS will be available by the end of December early January 2023.
    • Combination of offering a minimum of VM images and a playbook of Ansible (IT automation tool).
    • Account management (LDAP), file server (samba, NFS), remote desktop (rdp, vnc)
    • PC cluster construction (slurm, singularity)

Notice of HOKUSAI Maintenance

Supercomputer HOKUSAI BigWaterfall(HBW) and Data Science Infrastructure(HSS) will be stopped in the schedule below due to the planned power outage in Wako campus. At that time, regular maintenance will also be performed.

Downtime(HOKUSAI BW and SS):
from 5:00 p.m. on October 7 to 6:00 p.m. on October 11

For BW, note that job execution control will be performed before the downtime: Jobs that are expected not to end until the start time of the downtime will be not started. After resuming operation, the unstarted jobs will be started.

For SS, please stop VMs (instances) before the service is stopped. Any VMs that are running when the service is stopped will be forcibly terminated. VMs will not start automatically after the service is restarted, so please start it by yourself.
