SLURMCTLD(8)

NAME
slurmctld - The central management daemon of Slurm.

SYNOPSIS
slurmctld [OPTIONS...]

DESCRIPTION
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.

OPTIONS

-c  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.

-D  Debug mode. Execute slurmctld in the foreground with logging to stdout.

-f <file>
    Read configuration from the specified file. See NOTES below.

-h  Help; print a brief summary of command options.

-L <file>
    Write log messages to the specified file.

-v  Verbose operation. Multiple -v's increase verbosity.

-V  Print version information and exit.

ENVIRONMENT VARIABLES
The following environment variables can be used to override settings compiled into slurmctld.

SLURM_CONF
    The location of the SLURM configuration file. This is overridden by explicitly naming a configuration file on the command line.

NOTES
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.
