Resource Allocations on the Frontenac Cluster
This Wiki entry is meant to explain how resources are shared on the CAC Frontenac cluster. This includes default allocations in terms of Compute time as well as extended resources that were allocated by Compute Canada or that come from contributed systems. We also point out differences between the current Frontenac allocation scheme and the older scheme that was used on the now decommissioned SW/CAC clusters.
Our job scheduler on Frontenac is [SLURM https://slurm.schedmd.com/]. All resource allocations and limitations are applied through this scheduler. For a basic intro on how to use it, please see our scheduler help file.
Every user on our systems has at least one SLURM account, the default account. Users with access to extended resources have additional accounts corresponding to these allocations. These SLURM accounts have intrinsic restrictions and allow scheduling of jobs up to these limits.
