    "SLURM is a fault-tolerant and highly scalable cluster management and job
scheduling system for large and small clusters.  It allocates access to
resources (computer nodes) to users for some duration of time, provides a
framework for starting, executing, and monitoring work (typically a parallel
job) on a set of allocated nodes, and arbitrates contention for resources
by managing a queue of pending work.")
