How to Submit Jobs in the High Priority Queues:

By default, only the Faculty/PI user account can use the high priority queue against available SU. However, access can be granted to specific user(s) under their account by using the acct-manage command. The Faculty/PI must add the user to the project account using the acct-manage script.

For using the chargeable partitions, the following options must be added in the Slurm batch script:

#SBATCH -A "FAC_projectcode"
#SBATCH -q "FAC_projectcode"

The user must specify the high-priority account using #SBATCH -A "account" and the corresponding QoS using #SBATCH -q "account" in their job submission script. If these are not specified, the job may be assigned by default to the free-priority queue.

Example: If dcd and c3d are the Faculty/PI user account and the SRIC project code respectively, then the user should use the following lines in the Slurm batch script to use the partition "medium":

#SBATCH -p medium
#SBATCH -A dcd_c3d
#SBATCH -q dcd_c3d

The High-Priority Users are advised to check the priority of their submitted jobs using the sprio command. If the QoS is not receiving a higher priority, they should resubmit their jobs with the correct account specified to ensure efficient resource allocation and notify HPC Support.

How to check SU balance:

Use the command acct-manage command and select p option in the main menu to know the project details along available balance. Also, the high priority account users can view their latest account balance using hpabalance command.
