Re: [slurm-users] How to enforce memory contrains?

[Hermann Schwärzler]

Hi Rodrigo,

a possible solution is using

VSizeFactor=100

in slurm.conf.

With this settings, programs that try to allocate more memory than requested in the job's settings will fail. Be aware that this puts a limit on *virtual* memory, not on RSS. This might or might not be what you want as a lot of programs tend to allocate (a lot) more virtual memory than they really use (RSS).

Hello Slurm Users,



I don't know what I'm missing.

Thanks for your help

slurmd -V
slurm 20.02.6

slurm.conf
TaskPlugin=task/affinity,task/cgroup
ProctrackType=proctrack/cgroup

cgroup.conf
AllowedRAMSpace=100.0
AllowedSwapSpace=0.0
ConstrainRAMSpace=yes
ConstrainSwapSpace=yes
MemorySwappiness=0
CgroupAutomount=yes
ConstrainCores=yes

I'm having a hard time configuring slurm to kill jobs when they use more memory than requested. Also, I can't make jobs use only RAM, and some of them starts to use SWAP.
