       Slurm - Slurm Workload Manager overview.

       The  Slurm  Workload  Manager  is  an  open source, fault-tolerant, and
       highly scalable cluster management and job scheduling system for	 large
       and  small  Linux  clusters. Slurm requires no kernel modifications for
       its operation and is relatively self-contained. As a  cluster  resource
       manager,	 Slurm	has three key functions. First,	it allocates exclusive
       and/or non-exclusive access to resources	(compute nodes)	to  users  for
       some  duration  of time so they can perform work. Second, it provides a
       framework for starting, executing, and monitoring work (normally	a par-
       allel  job) on the set of allocated nodes.  Finally, it arbitrates con-
       tention for resources by	managing a queue of  pending  work.   Optional
       plugins can be used for accounting, advanced reservation, gang schedul-
       ing (time sharing for parallel  jobs),  backfill	 scheduling,  resource
       limits  by user or bank account,	and sophisticated multifactor job pri-
       oritization algorithms.

       Slurm has a centralized manager,	slurmctld, to  monitor	resources  and
       work.  There may	also be	a backup manager to assume those responsibili-
       ties in the event of failure. Each compute server (node)	has  a	slurmd
       daemon, which can be compared to	a remote shell:	it waits for work, ex-
       ecutes that work, returns status, and waits for more work. An  optional
       slurmdbd	 (Slurm	 DataBase  Daemon) can be used for accounting purposes
       and to maintain resource	limit information.

       Basic user tools	include	srun to	initiate jobs,	scancel	 to  terminate
       queued  or  running  jobs, sinfo	to report system status, and squeue to
       report the status of jobs. There	is also	an administrative  tool	 scon-
       trol  available to monitor and/or modify	configuration and state	infor-
       mation. APIs are	available for all functions.

       Slurm configuration is maintained in the	slurm.conf file.

       Man pages are available for all Slurm commands, daemons,	APIs, plus the
       slurm.conf  file.  Extensive documentation is also available on the in-
       ternet at <>.
