slurmdSection: Slurm Daemon (8)
Updated: Slurm Daemon
- Report node rebooted when daemon restarted. Used for testing purposes.
- Clear system locks as needed. This may be required if slurmd terminated
- 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.
- 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.
- 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.
- Print Generic RESource (GRES) configuration (based upon slurm.conf GRES merged with gres.conf contents for this node) and exit.
- Help; print a brief summary of command options.
- -L <file>
- Write log messages to the specified file.
- 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.
- 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.
- Verbose operation. Multiple -v's increase verbosity.
- -V, --version
- Print version information and exit.
- The location of the Slurm configuration file. This is overridden by
explicitly naming a configuration file on the command line.
- SIGTERM SIGINT
- slurmd will shutdown cleanly, waiting for in-progress rollups to finish.
- Reloads the slurm configuration files, similar to 'scontrol reconfigure'.
- Reread the log level from the configs, and then reopen the log file. This should be used when setting up logrotate(8).
- This signal is explicitly ignored.
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.
