Hi, just wanted to update this thread in case someone has a similar problem.
I managed to achieve this result by: - changing SelectTypeParameters=CR_Core_Memory To SelectTypeParameters=CR_CPU_Memory - giving the low priority job a very high "nice" value, near the end of the scale With this configuration, when I submit an high priority job, slurm stop running other low priority already-queued jobs to run my new job.
