Simple Linux Utility for Resource Management (or simply SLURM) is the name of computer software that performs 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.
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.
