NAME

       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-con-
       tained.	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,  exe-
       cuting,	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 responsibili-
       ties 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 pur-
       poses 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 infor-
       mation. 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 documenation is also available  on  the
       internet at <http://www.schedmd.com/slurmdocs/>.
