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/>.
