Job Accounting
Cores on a socket 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 socket even if it uses only one core on a socket. To simplify the process, users are required to request an entire socket through PBS. Odd core requests are rejected upon submission.
The cpuhour charge for each job will be as follows:
cores requested * ( job's endtime - job's starttime)
The showusage utility can be used to view your usage from January 01 through midnight of the previous day. For example,
