| .SH "NAME" |
| slurmd \- The compute node daemon for SLURM. |
| |
| .SH "SYNOPSIS" |
| \fBslurmd\fR [\fIOPTIONS\fR...] |
| |
| .SH "DESCRIPTION" |
| \fBslurmd\fR is the compute node daemon of Slurm. It monitors all tasks |
| running on the compute node , accepts work (tasks), launches tasks, and kills |
| running tasks upon request. |
| .TP |
| OPTIONS |
| .TP |
| \fB\-c\fR |
| Clear system locks as needed. This may be required if \fBslurmd\fR terminated |
| abnormally. |
| .TP |
| \fB\-d <file>\fR |
| Specify the fully qualified pathname to the \fBslurmstepd\fR program to be used |
| for sheperding user job steps. This can be useful for testing purposes. |
| .TP |
| \fB\-D\fR |
| Run slurmd in the foreground. Error and debug messages will be copied to stderr. |
| .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\-M\fR |
| Lock slurmd pages into system memory using mlockall(2) to disable |
| paging of the slurmd process. This may help in cases where nodes are |
| marked DOWN during periods of heavy swap activity. If the mlockall(2) |
| system call is not available, an error will be printed to the log |
| and slurmd will continue as normal. |
| .TP |
| \fB\-v\fR |
| Verbose operation. Multiple \-v'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 slurmd. |
| .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 \fBslurmd\fR specific |
| configuration parameters using a distinct configuration file |
| (e.g. timeouts). However, this special configuration file will not be |
| used by the \fBslurmctld\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. |
