Slurm is the batch system available. Any script can be submitted as a job with no changes, but you might want to see Writing SLURM jobs to customise it.
To submit a script as a serial job with default options enter the command:
sbatch yourscript.sh
You may query the queues to see the jobs currently running or pending with:
squeue
And cancel a job with
scancel <jobid>
See the Slurm documentation for more details on the different commands available to submit, query or cancel jobs.

Checking QoS setup
If you want to get all the details of a particular QoS on the system, you may run, for example:
sacctmgr list qos names=nf
Work in progress
Different limits on the different QoSs may be introduced or changed as the system evolves to its final configuration.
