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 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 parallel job)  on  the  set  of  allocated  nodes.   Finally,  it  arbitrates
       contention  for  resources  by  managing  a  queue  of  pending  work.   Optional plugins can be used for
       accounting, advanced reservation, gang scheduling (time sharing for parallel jobs), backfill  scheduling,
       resource limits by user or bank account, and sophisticated multifactor 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, 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
       scontrol  available  to monitor and/or modify configuration and state information. 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 internet at <https://slurm.schedmd.com/>.
