mpi.confSection: Slurm Configuration File (5)
Updated: Slurm Configuration File
Parameter names are case insensitive. Any text following a "#" in the configuration file is treated as a comment through the end of that line. Changes to the configuration file take effect upon restart of Slurm daemons, daemon receipt of the SIGHUP signal, or execution of the command "scontrol reconfigure" unless otherwise noted.
Settings from this configuration file can be viewed in the output of "scontrol show config". This configuration file can be included when using "configless" mode. Information from mpi.conf is read at startup or upon reconfigure by slurmctld and slurmd. Instances of slurmstepd for batch steps will receive information about the plugin requested from slurmd.
