       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 <http://slurm.schedmd.com/>.
