# Job Priority

Note: This document describes features added to SLURM version 2.0.

By default, SLURM assigns job priority on a First In, First Out (FIFO) basis. FIFO scheduling should be configured when SLURM is controlled by an external scheduler.

The PriorityType parameter in the slurm.conf file selects the priority plugin. The default value for this variable is "priority/basic" which enables simple FIFO scheduling.

SLURM version 2.0 includes the Multi-factor Job Priority plugin. This plugin provides a very versatile facility for ordering the queue of jobs waiting to be scheduled. For details and configuration information, see the Multi-factor Job Priority plugin page.
