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.:
LimitNOFILE=131072 LimitMEMLOCK=infinity LimitSTACK=infinity LimitMSGQUEUE=12345678 See https://www.baeldung.com/linux/ulimit-limits-systemd-units for the list of possibilities… -- Kind regards Franky Van: slurm-users <slurm-users-boun...@lists.schedmd.com> namens Ozeryan, Vladimir <vladimir.ozer...@jhuapl.edu> Datum: donderdag, 16 november 2023 om 21:05 Aan: slurm-us...@schedmd.com <slurm-us...@schedmd.com> Onderwerp: [slurm-users] ulimits 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, Vlad Ozeryan AMDS – AB1 Linux-Support vladimir.ozer...@jhuapl.edu Ext. 23966
