Intro

Shared issues

  1. Quotas on /project are all 1 TB. The Storage National team is working on a project/RAC based schema. Fortunately Lustre have announced group-based quotas but that will need installation. (Patrick Mann (talk) 20:12, 17 July 2017 (UTC))
  2. SLURM epilog does not fully clean up processes from ended jobs, especially if the job did not exit normally. (Greg Newby) Fri Jul 14 19:32:48 UTC 2017)
  3. Email from graham and cedar is still undergoing configuration. Therefore email job notifications from Slurm are failing. (Patrick Mann (talk) 17:17, 26 June 2017 (UTC))
    • Cedar email is working now (Patrick Mann (talk) 16:11, 6 July 2017 (UTC))
    • Graham email is working
  4. The SLURM 'sinfo' command yields different resource-type detail on graham and cedar. (Greg Newby) 16:05, 23 June 2017 (UTC))
  5. Local scratch on compute nodes has inconsistent naming. Cedar has /local and Graham has /localscratch.
  6. The status page at http://status.computecanada.ca/ is not updated automatically yet, so does not necessarily show correct, current status.
  7. "Nearline" capabilities are not yet available (see https://docs.computecanada.ca/wiki/National_Data_Cyberinfrastructure for a brief description of the intended functionality)
    • Update July 17: still not working. If you need your nearline RAC2017 quota then please ask CC support.

Cedar only

  • Environment variables such as $SCRATCH and $PROJECT are not yet set, although the filesystem are available. (Greg Newby) 16:10, 21 June 2017 (UTC))

Graham only

  • big memory nodes need to be added to the scheduler
  • no network topology information in the scheduler
