Job Accounting

CPU-Hour Job Charges

Jobs on the Cray X1E are charged based on their wall time and the number of MSPs the job makes unavailable to other jobs. Note that this is not always the same as the number of resources the job actually uses. For example, if a job uses one SSP, it will be allocated and charged for one MSP.

The cpuhour charge for each job will be as follows:

allocated MSP(s) * walltime
