       slurm - SLURM system overview.

DESCRIPTION

       The  Simple  Linux  Utility for Resource Management (SLURM) 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/>.
