Re: [HTCondor-users] howto set ulimit -l unlimited for openmpiscript or other condor jobs on debian 9 for htcondor 8.8?

[Tim Theisen <tim@xxxxxxxxxxx>]

Hello Harald,

The /etc/init.d/condor file is not used. Distributing it was a mistake
on our part.

So, we should modify the systemd configuration.

When updating the condor service, one should not modify the system
installed service file. Instead, create a file with overrides to the
distributed configuration. Here are the steps:

1. mkdir /etc/systemd/system/condor.service.d 2. Put the following 2 lines into
/etc/systemd/system/condor.service.d/condor.conf

[Service]
LimitMEMLOCK=unlimited

3. Force a systemd reload: systemctl daemon-reload

4. Finally, restart HTCondor: systemctl restart condor
