The SLURM Workload Manager is an open source, fault-tolerant and highly scalable cluster management and job scheduling system[1] used on the DEAC cluster. Formerly known as Simple Linux Utility for Resource Management (aka SLURM)[2], it provides three key functions:
Allocates exclusive and/or non-exclusive access to resources (compute nodes) to users for X period of time
Provides a framework for starting, executing, and monitoring work on allocated nodes
Arbitrates contention for resources by managing a queue of pending jobs
