    .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.

    .SH "OPTIONS"

    .TP
    \fB\--authinfo\fR
    Used with configless to set an alternate AuthInfo parameter to be used to
    establish communication with slurmctld before the configuration file has been
    retrieved. (E.g., to specify an alternate MUNGE socket location.)
    .IP

    .TP
    \fB\-b\fR
    Report node rebooted when daemon restarted. Used for testing purposes.
    .IP

    .TP
    \fB\-c\fR
    Clear system locks as needed. This may be required if \fBslurmd\fR terminated
    abnormally.
    .IP

    .TP
    \fB\-C\fR
    Print the actual hardware configuration (not the configuration from the
    slurm.conf file) and exit.
    The format of output is the same as used in \fBslurm.conf\fR to describe a node's
    configuration plus its uptime.
    .IP

    .TP
    \fB\-\-conf <node parameters>\fR
    Used in conjunction with the \fB\-Z\fR option. Used to override or define
    additional parameters of a dynamic node using the same syntax and parameters
    used to define nodes in the slurm.conf. Specifying any of \fBCPUs\fR,
    \fBBoards\fR, \fBSocketsPerBoard\fR, \fBCoresPerSocket\fR or
    \fBThreadsPerCore\fR will override the defaults defined by the \fB\-C\fR
    option. \fBNodeName\fR and \fBPort\fR are not supported.

    .br
    For example if \fIslurmd \-C\fR reports
    .nf
    NodeName=node1 CPUs=16 Boards=1 SocketsPerBoard=1 CoresPerSocket=8 ThreadsPerCore=2 RealMemory=31848
    .fi

    the following --conf specifications will generate the corresponding node definitions:
    .nf
    \-\-conf "Gres=gpu:2"
    \-\-conf "CPUs=16 RealMemory=30000 Gres=gpu:2"
    NodeName=node1 CPUs=16 RealMemory=30000 Gres=gpu:2"
    .fi
    .IP

    .TP
    \fB\-\-conf\-server <host>[:<port>]\fR
    Comma\-separated list of controllers, the first being the primary slurmctld. A
    port can (optionally) be specified for each controller. These hosts are where
    the slurmd will fetch the configuration from when running in "configless" mode.
    .IP

    .TP
    \fB\-d <file>\fR
    Specify the fully qualified pathname to the \fBslurmstepd\fR program to be used
    for shepherding user job steps. This can be useful for testing purposes.
    .IP

    .TP
    \fB\-D\fR
    Run slurmd in the foreground. Error and debug messages will be copied to stderr.
    .IP

    .TP
    \fB\-\-extra <arbitrary string>\fR
    Set "extra" data on node startup. If this is a json string and
    \fBSchedulerParameters=extra_constraints\fR is set in slurm.conf, then jobs may
    use the \-\-extra option to filter based on this "extra" data.
    .IP

    .TP
    \fB\-f <file>\fR
    Read configuration from the specified file. See \fBNOTES\fR below.
    .IP

    .TP
    \fB\-F[feature]\fR
    Start this node as a Dynamic Future node. It will try to match a node
    definition with a state of \fBFUTURE\fR, optionally using the specified
    feature to match the node definition.
    .IP

    .TP
    \fB\-G\fR
    Print Generic RESource (GRES) configuration (based upon slurm.conf GRES merged
    with gres.conf contents for this node) and exit.
    .IP

    .TP
    \fB\-h\fR
    Help; print a brief summary of command options.
    .IP
    .IP

    .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.

    It is suggested to set \fBLaunchParameters=slurmstepd_memlock\fR in
    \fBslurm.conf\fR(5) when setting \fB\-M\fR.
    .IP

    .TP
    \fB\-n <value>\fR
    Set the daemon's nice value to the specified value, typically a negative number.
    Also note the \fBPropagatePrioProcess\fR configuration parameter.
    .IP

    .TP
    \fB\-N <nodename>\fR
    Run the daemon with the given nodename. Used to emulate a larger system
    with more than one slurmd daemon per node. Requires that Slurm be built using
    the \-\-enable\-multiple\-slurmd configure option.
    .IP

    .TP
    \fB\-s\fR
    Change working directory of slurmd to SlurmdLogFile path if possible, or to
    SlurmdSpoolDir otherwise. If both of them fail it will fallback to /var/tmp.
    .IP

    .TP
    \fB\-\-systemd\fR
    Use when starting the daemon with systemd. This will allow slurmd to notify
    systemd of the new PID when using 'scontrol reconfigure'.
    .IP

    .TP
    \fB\-v\fR
    Verbose operation. Multiple \-v's increase verbosity.
    .IP

    .TP
    \fB\-V\fR, \fB\-\-version\fR
    Print version information and exit.
    .IP

    .TP
    \fB\-Z\fR
    Start this node as a Dynamic Normal node. If no \fB\-\-conf\fR is specified,
    .TP
    \fBSLURM_DEBUG_FLAGS\fR
    Specify debug flags for slurmd to use. See DebugFlags in the
    \fBslurm.conf\fR(5) man page for a full list of flags. The environment
    variable takes precedence over the setting in the slurm.conf.
    .IP

    .SH "SIGNALS"

    .TP
    \fBSIGTERM SIGINT\fR
    \fBslurmd\fR will shutdown cleanly, waiting for in\-progress rollups to finish.
    .IP

    .TP
    \fBSIGHUP\fR
    Reloads the slurm configuration files, similar to 'scontrol reconfigure'.
    .IP

    .TP
    \fBSIGUSR2\fR
    Reread the log level from the configs, and then reopen the log file.  This
    should be used when setting up \fBlogrotate\fR(8).
    .IP

    .TP
    \fBSIGPIPE\fR
    This signal is explicitly ignored.
    .IP

    .SH "CORE FILE LOCATION"
    If slurmd is started with the \fB\-D\fR option then the core file will be
    written to the current working directory.
    Otherwise if \fBSlurmdLogFile\fR 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 \fBSlurmdSpoolDir\fR directory, or "/var/tmp/" as a last resort. If
    none of the above directories can be written, no core file will be
    produced.

    .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.

    If you are using configless mode with a login node that runs a lot of client
    commands, you may consider running \fBslurmd\fR on that machine so it can
