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.
