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.

       -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 <hostname>
              Run the daemon with the given hostname. 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     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.
