How to limit the cpu usage of slurm?

So I am running a slurm job across 2 laptops (2 nodes), and I notice both laptop gets insanely laggy, to the point that the mouse could not even move. When I uses htop I saw the job was using 4 cores in 100% usage. I know for sure that the job does not take up that many cpu usage. How do I make slurm so that it uses only the required amount of cpu power?

Slurm does not put any additional load onto the CPUs of your node. Besides what it needs for slurmd/slurmstepd, which is not much. If your job has access to four cores and you only use one, the others will be idle.

Maybe your program does something unexpected?
