Slurm job based user access

To ensure security while running jobs on the cluster, users can be assigned permissions to access compute nodes only while their jobs are running. To enable the feature:

cd scheduler
ansible-playbook job_based_user_access.yml -i inventory

Note

• The inventory queried in the above command is to be created by the user prior to running omnia.yml as scheduler.yml is invoked by omnia.yml

• Only users added to the ‘slurm’ group can execute slurm jobs. To add users to the group, use the command: usermod -a -G slurm <username>.
