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. |
Select the account in your batch job
Batch jobs are submitted by a user account to the compute system.

To charge the account myaccount
add the following line to the job script.
#SBATCH --account=myaccount
