Preemption Job

Preemption job is available in general using a new QOS: preemptible.

Jobs that request this QOS will be eligible to be run on reserved condo nodes. However, if other jobs with the appropriate QOS are waiting on those same resources, the preemptible jobs are killed to allow the higher QOS jobs start. Preemption will be done with a minimum runtime before preemption of 15 minutes. Preemptible jobs will be charged at the same rate.

The preemptable job will be treated as the regular job considering the ‘Job Size Policy’ (# of jobs and # of cores)
