Hi all;

I'm testing slurm preempt with PreemptType=preempt/qos and PreemptMode=suspend,gang in slurm.conf. But job with high-qos not preempt the job with low-qos.

My configuration followed:

slurm version: 23.11.4

test node : 8 CPUS and 8GB RAM

QoS Configuration: 

Partition Configuration: 

Job Submission: I submitted test jobs, one with --qos=low-qos and--partition=low , resources 4 CPUs, 4GB memory, and later, a  job  with --qos=high-qos and  --partition=g1 requesting more resources( 5 CPUs, 5GB memory).

​

Did anyone else encounter this issue or any additional steps I might need to take to correctly enable QoS-based preemption in our SLURM setup.

Best regards,

Liyar
