Choosing RHEL-7 or RHEL-8

To target a specific OS in your job scripts, use the SBATCH options: --constraint=el7 or --constraint=el8. If neither are specified, the scheduler will not consider operating system in placing your jobs. These constraints can be entered in the “Additional SLURM Options” field of Open onDemand forms.
