slurmctld - The central management daemon of Slurm.
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.
Read configuration from the specified file. See NOTES below.
Help; print a brief summary of command options.
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.)
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.
CORE FILE LOCATION
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
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.
