'''Simple Linux Utility for Resource Management''' (or simply '''SLURM''') is the name of computer software that performs [[job scheduler|job scheduling]]. It provides three key functions. First it allocates exclusive and/or non-exclusive access to resources (computer nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, executing, and monitoring work (typically a parallel job) on a set of allocated nodes. Finally, it arbitrates contention for resources by managing a queue of pending work.
SLURM's design is very modular with dozens of optional plugins. In its simplest configuration, it can be installed and configured in a couple of minutes. More sophisticated configurations provide database integration for accounting plus management of resource limits and workload prioritization. SLURM also works with several meta-schedulers such as [[Moab Cluster Suite]], [[Maui Cluster Scheduler]], and [[Platform LSF]].
==History ==
SLURM was developed as a collaborative effort primarily by [[Lawrence Livermore National Laboratory]], Linux NetworX, [[Hewlett-Packard]], and [[Groupe Bull]] as an [[Open Source]] resource manager. It has since evolved into a sophisticated batch scheduler capable of satisfying the requirements of many large computer centers. SLURM is currently used on many of the largest computers in the world.
