ASPIRE 2A+: Expect Longer Wait Times for Large Jobs from 14 Oct 2025, 6:00 PM (SGT)​

/in , /by

Dear ASPIRE 2A+ Users,

Please note that starting from 14 October 2025 (Tuesday), 6:00 PM (SGT), a project reservation will temporarily reduce the general resource pool in the ASPIRE 2A+ system.

Impact:

  • Large jobs (More than 8 GPUs): Expect longer queue wait times.
  • Small jobs (1–8 GPUs): No impact.

Tips:

  • To reduce delays, please enable checkpointing or pre-emption where possible.
  • Users are encouraged to schedule job runs between 6:00 PM to 10:00 AM to leverage off-peak hours, which may result in shorter queue times.

Thanks for your patience and cooperation. Kindly look out for updates via the MOTD or email announcement if there are any changes to the arrangement.

Should you have any questions or need assistance, please contact our Helpdesk via the Service Desk Portal or email us at [email protected].

Thank you.

Warm regards,
The NSCC Team
