How to use QOS parameters
QoS (Quality of Service)
We have implemented Quality of Service (QoS) for MonARCH.
The QoS can be added to each job that is submitted to Slurm. The quality of service associated with a job will affect the job in three ways:
- Job Scheduling Priority
- Job Preemption
- Job Limits

All users currently have a default QOS assigned to them. There is no need to specify it in normal usage. Users may be asked to add a QOS field for specific reason, i.e. they belong to a partner share.
To view the current list of all QOSs and their current values, run the following command. It also lists the values of QOS that you have access to.
mon_qos
How to use the QOS value
To add a QOS place this in your SBATCH script, you add a line like this in your Slurm submission script.
#SBATCH --qos=normal
An example Slurm job script
#!/bin/bash
#SBATCH --job-name=MyJob
#SBATCH --qos=partner
#SBATCH --ntasks=2
