slurm (workload manager)
Slurm is an open-source workload manager designed for Linux clusters
of all sizes. 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.
The SLURM controller (slurmctld) can run without elevated privileges,
so it is recommended that a user "slurm" be created for it before Slurm
is executed.
# groupadd -g 311 slurm
# useradd -u 311 -d /var/lib/slurm -s /bin/false -g slurm slurm
Next, a configuration file can be build using your favorite web browser
and the file /usr/doc/slurm-<VERSION>/html/configurator.html.
Optional dependencies:
HWLOC=yes|no (default: no), requires hwloc
RRDTOOL=yes|no (default: no), requires rrdtool
NUMA auto-detected, requires numactl
Warning for 32-bit users: according to slurm's developers: 32-bit
support is deprecated, and not tested regularly. Use at your own risk.
