Hi Vlad

If you are using the systemd services, then you can change the value in the file /usr/lib/systemd/system/slurmd.service, e.g.:


See https://www.baeldung.com/linux/ulimit-limits-systemd-units for the list of possibilities...

-- Kind regards

Hello everyone,

I am having the following issue, on the compute nodes "POSIX message queues" is set to unlimited for soft and hard limits.
However, when I do "srun -w node01 --pty bash -I" and then once I am in the node I do "cat /proc/SLURMPID/limits" it shows that "Max msgqueue size" is set to 819200 for both soft and hard limits.
Where is it being set and how do I change it?

Thank you,
