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.
