Job Charge
The charge of core hours for a batch job depends on the number of nodes, the wallclock time used by the job, and the charge rate for the partition used. For a batch job with

A job on 48 cores on partition large96:shared (96 cores per node, 144 core hour) has a reservation for num = 48/96 = 0.5 nodes. Assuming a wallclock time of 3 hours yields a job charge of 216 core hour. |

Batch jobs and project accounts
Running batch jobs with a User Account, the user can access two different accounts in general. The NHR centers distinguish between
...
Project Account
A compute project holds a bank account for the project. This project account contains a compute capacity in core hours. At the beginning of each quarter the account is granted by the number of core hours following the funding decision for the given compute project. A project account holds at least 4x300 k core hours per year. Unused core hours are transferred to the subsequent quarter, but only one time.
