If you have a systemd capable OS: ----------------------------------------------- /usr/lib/systemd/system/slurmd.service --> Start slurmd client, so exec it in compute nodes /usr/lib/systemd/system/slurmdbd.service --> Slurm db script, if you use accounting through a database (most cases), on accounting node (maybe same than head node) /usr/lib/systemd/system/slurmctld.service --> Slurm controller, exec it in head nodes
Maybe you will have to tune systemd scripts accordingly to slurm.conf file depending on your OS. If you still use an OS with rc scripts: ------------------------------------------------ /etc/rc.d/init.d/slurmdbd -->Slurm db script, if you use accounting through a database (most cases), on accounting node (maybe same than head node) /etc/rc.d/init.d/slurm --> Detects if you are compute or head node and starts slurmd or both slurmd and slurmctld daemons.
