Jobs on OLCF clusters are scheduled in full node increments; a node’s cores cannot be allocated to multiple jobs. Because the OLCF charges based on what a job makes unavailable to other users, a job is charged for an entire node even if it uses only one core on a node. To simplify the process, users are given a multiples of entire nodes through PBS.
Note: Users are given a multiples of entire nodes through PBS, and associated allocations are reduced by the number of cores per node, regardless of actual CPU utilization.
