# The CC slurm configuration preferentially encourages whole-node jobs. Users should if possible request whole-nodes rather than per-core resources. ([[User:Pjmann|Patrick Mann]] ([[User talk:Pjmann|talk]]) 20:15, 17 July 2017 (UTC))
Problems that affect many users and are being investigated, such as a cluster-wide malfunction or outage, are on [https://status.alliancecan.ca/ the Alliance Status page]. This "Known issues" page describes problems that affect many users but that may take some time to repair, or are not planned for repair at this time. Problems that only affect a specific software package are described on the wiki page for that software package.  
# Quotas on <code>/project</code> 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. ([[User:Pjmann|Patrick Mann]] ([[User talk:Pjmann|talk]]) 20:12, 17 July 2017 (UTC))
