Thanks for pointing me to DefMemPerCPU. This is the obvious solution, I
somehow overlooked that.

In our configuration we have DefMemPerCPU=1024 as part of the partition

I don't know the answer to your question if that is expected behavior,
but it would keep you from having to do something with a plugin.

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