 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 
-conflicting requests for resources by managing a queue of pending work.

 <h3>Configuration</h3>
 
-The SLURM configuration file includes a wide variety of parameters. 
-A full description of the parameters is included in the <i>slurm.conf</i> 
-man page. 
-Rather than duplicate that information, a sample configuration file 
-is shown below.
-Any text following a "#" is considered a comment.
-The keywords in the file are not case sensitive, 
-although the argument typically is (e.g. "SlurmUser=slurm" 
-might be specified as "slurmuser=slurm").
-The control machine, like all other machine specifications can 
-include both the host name and the name used for communications. 
-In this case, the host's name is "mcri" and the name "emcri" is 
-used for communications. The "e" prefix identifies this as an 
-ethernet address at this site. 
-Port numbers to be used for communications are specified as 
-well as various timer values. 
-On DPCS systems set FirstJobId to 65536 or higher. 
-This will permit DPCS to specify a SLURM job id to match its own job id 
-without conflicts from jobs submitted to SLURM by other means.
-<p>
-A description of the nodes and their grouping into non-overlapping 
-partitions is required.
-Partition and node specifications use node range expressions to 
-identify nodes in a concise fashion. 
-This configuration file defines a 1154 node cluster for SLURM, but 
-might be used for a much larger cluster by just changing a 
-few node range expressions.
