'''Simple Linux Utility for Resource Management''' (or simply '''SLURM''') is an [[opensource]] software that performs [[job scheduler|job]] schedulingfor many of the world's [[supercomputer]]s and computer clusters. 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 is the batch system of the world's fastest [[TOP500]] supercomputer, China's [[Tianhe-I]]. It is designed to handle thousands of nodes and can sustain throughput of 120,000 jobs per hour. While complex configuration options are available, simple configurations can be established in a few minutes.
