NAME

       slurmd - The compute node daemon for Slurm.

SYNOPSIS

       slurmd [OPTIONS...]

DESCRIPTION

       slurmd  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.

       OPTIONS

       -b     Report node rebooted when daemon restarted. Used for testing purposes.

       -c     Clear system locks as needed. This may be required if slurmd terminated abnormally.

       -C     Print actual hardware configuration and exit. The format of output is the  same  as
              used in slurm.conf to describe a node's configuration plus it's uptime.

       -d <file>
              Specify  the  fully  qualified  pathname  to  the slurmstepd program to be used for
              shepherding user job steps. This can be useful for testing purposes.

       -D     Run slurmd in the foreground. Error and debug messages will be copied to stderr.

       -f <file>
              Read configuration from the specified file. See NOTES below.

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

       -h     Help; print a brief summary of command options.

       -L <file>
              Write log messages to the specified file.

       -M     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.

       -n <value>
              Set the daemon's nice value to the specified value, typically  a  negative  number.
              Also note the PropagatePrioProcess configuration parameter.

       -N <nodename>
              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.

       -v     Verbose operation. Multiple -v's increase verbosity.

       -V, --version
              Print version information and exit.

ENVIRONMENT VARIABLES

       The following environment variables can be used to override settings compiled into slurmd.

       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 slurmd is started with the -D option then the core file will be written to the  current
       working  directory.   Otherwise  if SlurmdLogFile 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 SlurmSpoolDir directory, or "/var/tmp/" as
       a last resort. If none of the above directories can be  written,  no  core  file  will  be
       produced.

NOTES

       It  may  be  useful  to experiment with different slurmd specific configuration parameters
       using a distinct configuration file (e.g. timeouts).  However, this special  configuration
       file  will  not  be  used  by  the  slurmctld  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.
