NAME
     Slurm - Slurm Workload Manager overview.

DESCRIPTION
     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 ac-
     cess  to  resources  (compute  nodes) to users for some duration of time so
     they can perform work. Second, it provides a framework for  starting,  exe-
     cuting,  and  monitoring work (normally a parallel job) on the set of allo-
     cated nodes.  Finally, it arbitrates contention for resources by managing a
     queue of pending work.  Optional plugins can be used  for	accounting,  ad-
     vanced reservation, gang scheduling (time sharing for parallel jobs), back-
     fill scheduling, resource limits by user or account, and sophisticated mul-
     tifactor job prioritization algorithms.

     Slurm  has a centralized manager, slurmctld, to monitor resources and work.
     There may also be a backup manager to assume those responsibilities 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, executes that work, re-
     turns 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 scontrol available  to
     monitor  and/or modify configuration and state information. APIs are avail-
     able 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 internet
     at <https://slurm.schedmd.com/>.
