Resource Limits

  1. Per node limits
  2. Per Partition Limits

Some of the resource limits we have in place are based on the hardware configuration of the compute nodes. For example, the maximum amount of memory a job can request on a compute node is just below the amount of physical RAM in that node to ensure that the operating system has enough RAM to function and not result in the node running out of memory.

Some of the resource limits we have in place (such as the walltime and job size limits) are in place to ensure that the available resources are fairly shared between users. Such limits may be reviewed and amended from time to time.
