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

Hello together,
I have a special question regarding to set up the limit of max. open
files under Linux.
It is in case of this about the value of the soft - files, not about the
value for the hard files (see: ulimit-Sn)
Some users of the HPC use a large number of files for the processing in
your application.
These applications break off " too many files open " with the error message.
The attitude of the parameters does not have any effects here since no
"LOGIN" is carried out via SLURM via " etc/security/limits.conf ".
Who has already had to do with this subject and perhaps who can help me
here?
*Best regards….*
