[slurm-users] limiting memory usage when submission doesn't specify memory requirements?

[Matthias Leopold]

Hi,

I'm testing how limiting memory resources works in Slurm.
I'm using TaskPlugin=affinity,cgroup (slurm.conf) and 
ConstrainRAMSpace=yes (cgroup.conf) and have set a MaxMemPerCPU limit on 
the partition.
To my surprise MaxMemPerCPU is enforced as long as the job submission 
requests a memory limit (like --mem-per-cpu), but isn't enforced when 
job submission doesn't request a memory limit. Is this really expected 
behaviour? How do I constrain these jobs? Force requesting memory limit 
with submission plugin?

thx
Matthias
