| .SH "NAME" |
| slurmctld \- The central management daemon of Slurm. |
| .SH "SYNOPSIS" |
| \fBslurmctld\fR [\fIOPTIONS\fR...] |
| .SH "DESCRIPTION" |
| \fBslurmctld\fR 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 \fBslurmctld\fR, |
| there may be a backup server to assume these functions in the event that |
| the primary server fails. |
| .TP |
| OPTIONS |
| .TP |
| \fB\-c\fR |
| Clear all previous \fBslurmctld\fR 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. |
| .TP |
| \fB\-D\fR |
| Debug mode. Execute \fBslurmctld\fR in the foreground with logging to stdout. |
| .TP |
| \fB\-f <file>\fR |
| Read configuration from the specified file. See \fBNOTES\fR below. |
| .TP |
| \fB\-h\fR |
| Help; print a brief summary of command options. |
| .TP |
| \fB\-L <file>\fR |
| Write log messages to the specified file. |
| .TP |
| \fB\-v\fR |
| Verbose operation. Multiple \fB\-v\fR's increase verbosity. |
| .TP |
| \fB\-V\fR |
| Print version information and exit. |
| |
| .SH "ENVIRONMENT VARIABLES" |
| The following environment variables can be used to override settings |
| compiled into slurmctld. |
| .TP 20 |
| \fBSLURM_CONF\fR |
| The location of the SLURM configuration file. This is overridden by |
| explicitly naming a configuration file on the command line. |
| |
| .SH "NOTES" |
| It may be useful to experiment with different \fBslurmctld\fR specific |
| configuration parameters using a distinct configuration file |
| (e.g. timeouts). However, this special configuration file will not be |
| used by the \fBslurmd\fR 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, \fBslurm.conf\fR. |
