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.
-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
Read configuration from the specified file. See NOTES below.
-h Help; print a brief summary of command options.
Write log messages to the specified file.
-R 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.)
-v Verbose operation. Multiple -v’s increase verbosity.
-V Print version information and exit.
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.
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 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,
