       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.


       -B     Do not recover state of BlueGene blocks when running on a bluegene system.

       -c     Clear all previous slurmctld state from its last checkpoint.  With this option, all
              jobs,  including  both  running  and  queued, and all node states, will be deleted.
              Without this option, previously running jobs will  be  preserved  along  with  node
              State of DOWN, DRAINED and DRAINING nodes and the associated Reason field for those
              nodes.  NOTE: It is rare you would ever want to use this in production as all  jobs
              will be killed.

       -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.

       -n <value>
              Set the daemon's nice value to the specified value, typically a negative number.

       -r     Recover  partial  state  from  last  checkpoint: jobs and node DOWN/DRAIN state and
              reason information state.  No partition state is recovered.  This  is  the  default

       -R     Recover  full state from last checkpoint: jobs, node, and partition state.  Without
              this option, previously running jobs will be preserved along  with  node  State  of
              DOWN,  DRAINED  and DRAINING nodes and the associated Reason field for those nodes.
              No other node or partition state will be preserved.

       -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

       SLURM_CONF          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,  provided  SlurmUser has write permission on the directory.  Otherwise the core file
       will be written to the StateSaveLocation, or "/var/tmp/" as a last resort. If none of  the
       above directories have write permission for SlurmUser, no core file will be produced.  The
       command "scontrol abort" can be used to abort the slurmctld daemon  and  generate  a  core


       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.
