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 its uptime.

       --conf-server <host>[:<port>]
              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.

       -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.

       -F[feature]
              Start  this  node as a Dynamic Future node. It will try to match a node definition with a state of
              FUTURE, optionally using the specified feature to match the node definition.

       -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.

              It is suggested to set LaunchParameters=slurmstepd_memlock in slurm.conf(5) when setting -M.

       -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.

       -s     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.

       -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.

SIGNALS

       SIGTERM SIGINT
              slurmd will shutdown cleanly, waiting for in-progress rollups to finish.

       SIGHUP Reloads the slurm configuration files, similar to 'scontrol reconfigure'.

       SIGUSR2
              Reread the log level from the configs, and then reopen the log file.  This  should  be  used  when
              setting up logrotate(8).

       SIGPIPE
              This signal is explicitly ignored.

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.

       If  you  are using configless mode with a login node that runs a lot of client commands, you may consider
       running slurmd on that machine so it can manage a cached version of the configuration  files.  Otherwise,
       each  client  command  will  use  the  DNS  record  to  contact  the controller and get the configuration
       information, which could place additional load on the controller.
