The CC slurm configuration preferentially encourages whole-node jobs. Users should if possible request whole-nodes rather than per-core resources. (Patrick Mann (talk) 20:15, 17 July 2017 (UTC))
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))
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)
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
The SLURM 'sinfo' command yields different resource-type detail on graham and cedar. (Greg Newby) 16:05, 23 June 2017 (UTC))
Local scratch on compute nodes has inconsistent naming. Cedar has /local and Graham has /localscratch.
The status page at http://status.computecanada.ca/ is not updated automatically yet, so does not necessarily show correct, current status.
"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.

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 scheduling is not properly running small jobs. Working on the problem. (Patrick Mann (talk) 20:14, 17 July 2017 (UTC))
big memory nodes need to be added to the scheduler
no network topology information in the scheduler
