SLURM is a reliable, efficient, open source, fault-tolerant, job and compute resource manager with features
that make it suitable for large-scale, high performance computing environments. SLURM can report on
machine status, perform partition management, job management, and job scheduling.

The

SLURM Reference Manual is available on the HP XC Documentation CD-ROM and from the following

Web site:

http://www.llnl.gov/LCdocs/slurm/

SLURM manpages are also available online on the HP XC system.

As a system resource manager, SLURM has the following key functions:

•

Allocate exclusive and/or non-exclusive access to resources (compute nodes) to users for some duration
of time so they can perform work

•

Provide a framework for starting, executing, and monitoring work (normally a parallel job) on the set
of allocated nodes

•

Arbitrate conflicting requests for resources by managing a queue of pending work

The srun command submits and controls jobs that run under SLURM management. The srun command is
used to submit interactive and batch jobs for execution, allocate resources, and initiate job steps.

The srun command handles both serial and parallel jobs.
