[slurm-users] Increasing the OpenFile under SLURM ....

[Marcus Wagner]

Hi Matthias,

the jobs are always children of slurmd, so they inherit slurmds 
settings. So you have to modify the systemd-unit, e.g. like the following:


[Service]
LimitNOFILE=51200
LimitMEMLOCK=infinity
LimitSTACK=infinity
LimitCORE=8388608:infinity


Best
Marcus
