[slurm-users] What's the best way to suppress core dump files from jobs?

[Patrick Goetz]

Or even better, don't think about it.  If you type

   sudo systemctl edit slurmd

this will open an editor.  Type your changes into this and save it and 
systemd will set up the snippet file for you automatically (in 
etc/systemd/system/slurmd.service.d/).
