Job Accounting
A node’s cores cannot be allocated to multiple jobs. Because the NCCS charges based on what a job makes unavailable to others, a job is charged for an entire node even if it uses only one core on a node. To simplify the process, users are required to request an entire node through PBS (4 cores on the XT4 or 12 cores on the XT5). Odd core requests are rejected upon submission.
The project utilization reports page in the general support section provides more information on how project utilization is calculated and how usage can be viewed.
