Subject: [CONFIG] Add smpi/plugin/lb/migration-frequency option
X-Git-Tag: v3_21~559^2~1

[CONFIG] Add smpi/plugin/lb/migration-frequency option

This needs to be moved to the plugin file, but unfortunately, when the
smpirun command is parsed, the plugin is not yet initialized and hence
an error is thrown (since this option is not yet known).
