Shared issues

• 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)

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))
