Overview

mrmctl allows an admin to query, list, modify, and ping the resource managers and allocation managers in Moab. mrmctl also allows for a queue (often referred to as a class) to be created for a resource manager.

By default, this command can be run by level 1 and level 2 Moab administrators (see ADMINCFG).
