Outage schedule

Grid Engine will not schedule any job with a run time (h_rt) that extends into the beginning of a planned outage period. This is so the job will not be terminated prematurely when the system goes down.

  • No planned outages
  • Glooscap and Placentia will no longer be operated by ACENET after 2019 March 31.


  • The issues with the A/C unit, that occurred over the holidays have been fixed and it is working as intended. The compute nodes are available again. Placentia is still scheduled to be decommissioned at the end of March.
14:03, January 7, 2019 (AST)
  • Due to an issue with an A/C unit, some compute (up to cl107) has been taken down. Repairs have completed, but at ITS request, we are leaving the nodes down until Jan 3.

  • Glooscap is back in service after a planned interruption this weekend (Sep 7-10). The metadata server component of the file system has been relocated and a full fschk has been run. We hope this will alleviate file system load problems.
