Report an issue
- Please report issues to the technical support team.
- The status page at http://status.computecanada.ca/ is not updated automatically yet, so may lag in showing current status.
Scheduler issues
- The CC Slurm configuration encourages whole-node jobs. When appropriate, users should request whole-node rather than per-core resources. See Job Scheduling - Whole Node Scheduling.
- By default, the job receives environment settings from the submitting shell. This can lead to irreproducible results if it's not what you expect. To force the job to run with a fresh-like login environment, you can submit with --export=none or add #SBATCH --export=NONE to your job script.
Quota and filesystem problems
Quota errors on /project filesystem
- This topic has been moved to Frequently Asked Questions.
Nearline
- Nearline capabilities are not yet available; see https://docs.computecanada.ca/wiki/National_Data_Cyberinfrastructure for a brief description of the intended functionality.
- July 17 update: still not working. If you need your nearline RAC2017 quota, contact technical support.
Missing symbolic links to project folders
- Upon login to the new clusters, symbolic links are not always created in the user's account, as described in Project layout. If this is the case, please verify that your access to the cluster is enabled on this page https://ccdb.computecanada.ca/services/resources.
Cedar only
Nothing to report at this time.
Graham only
- /home is on an NFS appliance that does not support ACLs, so setfacl/getfacl doesn't work there.
- Workaround: use the /project or /scratch filesystems instead.
- Might be resolved by an update or reconfiguration.
- diskusage_report (and alias 'quota') do not report on Graham /home (FIXED as of 2017-11-27)
- Compute nodes cannot access Internet
- Solution: Contact technical support to request exceptions to be made; describe what you need to access and why.
- Crontab is not offered on Graham.
Other issues
- Modules don't work for shells other than bash(sh) and tcsh.
- Workaround: (this appears to work but not tested extensively)
- source $LMOD_PKG/init/zsh
- source $LMOD_PKG/init/ksh
