slurmctld - The central management daemon of Slurm.


slurmctld [OPTIONS...]


slurmctld is the central management daemon of Slurm. It monitors all other Slurm daemons and resources, accepts work (jobs), and allocates resources to those jobs. Given the critical functionality of slurmctld, there may be a backup server to assume these functions in the event that the primary server fails.
Clear all previous slurmctld state from its last checkpoint. If not specified, previously running jobs will be preserved along with the state of DOWN, DRAINED and DRAINING nodes and the associated reason field for those nodes.
Debug mode. Execute slurmctld in the foreground with logging to stdout.
-f <file>
Read configuration from the specified file. See NOTES below.
Help; print a brief summary of command options.
-L <file>
Write log messages to the specified file.
Recover full state from last checkpoint. Normally the slurmctld will only recover information about job, and node information. With this option state will be recovered for partition information also. (Warning: When using this option any changes to partitions in the slurm.conf file will be ignored on next restart or reconfig.)
Verbose operation. Multiple -v's increase verbosity.
Print version information and exit.


The following environment variables can be used to override settings compiled into slurmctld.
The location of the SLURM configuration file. This is overridden by explicitly naming a configuration file on the command line.


If slurmctld is started with the -D option then the core file will be written to the current working directory. Otherwise if SlurmctldLogFile is a fully qualified path name (starting with a slash), the core file will be written to the same directory as the log file. Otherwise the core file will be written to the StateSaveLocation. The command "scontrol abort" can be used to abort the slurmctld daemon and generate a core file.


It may be useful to experiment with different slurmctld specific configuration parameters using a distinct configuration file (e.g. timeouts). However, this special configuration file will not be used by the slurmd daemon or the Slurm programs, unless you specifically tell each of them to use it. If you desire changing communication ports, the location of the temporary file system, or other parameters used by other Slurm components, change the common configuration file, slurm.conf.
