Subject: ASPIRE 1 Scheduled System Maintenance from 7 June 2019, 3pm to 12 June 2019, 12pm due to Building Power Shutdown

Dear ASPIRE 1 Users,

The building owners, JTC, have planned the annual power shutdown of the Fusionopolis building on 7 June 2019. As such the ASPIRE 1 system will be affected and will be shut down from 7 June 2019 (Friday), 3:00pm to 12 June 2019 (Wednesday), 12:00pm.

We are also taking this opportunity to extend the shutdown period to carry out critical works to the data centre and to ASPIRE 1 itself. Please note that this shutdown exercise is longer than usual. Details of the shutdown maintenance can be found below.

IMPORTANT

In preparation for the power shutdown, please take note of the following dates and times:

1. 2 June 2019 (Sunday), 3pm:

  • All long queues will stop dispatching jobs from the above date and time till the end of the shutdown. This is to ensure jobs do not get terminated during the shutdown period.
  • Jobs which can be completed before the shutdown may still be dispatched manually, subject to the availability of resources.

2. 6 June 2019 (Thursday), 3pm:

  • Normal queues will stop dispatching jobs.
  • Jobs which can be completed before the shutdown may still be dispatched manually, subject to the availability of resources.

3. 7 June 2019 (Friday), 3pm:

  • All users will be logged out of the system.
  • All remaining running jobs will be allowed to terminate gracefully before the system shuts down.

4. 10 June 2019 (Monday), 9am:

  • โ€‹We will also be upgrading AMS (i.e Allocation Management System). However with this upgrade all jobs that have not been dispatched may be lost. Please check your jobs and resubmit them if required.

5. 12 June 2019 (Wednesday), 12pm:

  • ASPIRE 1 system will be brought back online and made available to users.

Shutdown and Maintenance Details –

The following activities will be carried out during the shutdown period from 7 June (Friday), 3pm to 12 June (Wednesday), 12pm:
1. JTC will be carrying out annual maintenance works to the electrical supply of the entire Fusionopolis building as mandated by law
2. NSCC will be replacing all the circuit breakers in the data centre. This is an added safety measure to reduce the likelihood of short circuits in the data centre.
3. NSCC will be upgrading Lustre (i.e the scratch file system) from version 2.07 to version 2.10. The new version of Lustre will address any potential compatibility issues.
4. NSCC will be upgrading the allocation management system (AMS) component of PBS. With this upgrade the occasional qstat or qsub timeout issues encountered should be mitigated. However, all jobs which have not been dispatched may be lost.
