<h2>Using the Consumable Resource Node Allocation Plugin: <b>select/cons_res</b></h2>
<ol start=1 type=1>
<li><b>SLURM v0.5 and up to SLURM v1.1: <u>ONLY</u> CPUs as a consumable resource</b></li>
<ul>
<li>Managing <b>CPUs</b> as a consumable resource means that SLURM will
not overallocate CPUs. In this implementation it is possible to oversubscribe
memory if co-located jobs are using more memory than is available on the node.
See features for SLURM 1.2 (below) for memory as a consumable resource.</li>
<li>The consumable resource plugin is enabled via SelectType in the
slurm.conf (e.g. <i>SelectType=select/cons_res</i>).</li>
<pre>
#
# "SelectType" : node selection logic for scheduling.
# "select/bluegene" : the default on BlueGene systems, aware of
# system topology, manages bglblocks, etc.
# "select/cons_res" : allocate individual consumable resources
# (i.e. processors, memory, etc.)
# "select/linear" : the default on non-BlueGene systems,
# no topology awareness, oriented toward
# allocating nodes to jobs rather than
# resources within a node (e.g. CPUs)
#
# SelectType=select/linear
SelectType=select/cons_res
</pre>
<li>The <b>select/cons_res</b> plug-in requires SHARED=No at the
partition level.</li>
<li>Using the <i>--overcommit</i> or <i>-O</i> switch in the
<b>select/cons_res</b> environment is only possible when users
request dedicated nodes using <i>--exclusive</i>.</li>
Overcommiting CPUs in a non-dedicated environment would impact
jobs that are co-located on the nodes which is not a desirable
feature. This feature is available in SLURM 1.2 (see below).</li>
</ul>
<li><b>SLURM 1.2 and newer versions of SLURM</b></li>
<li><b>SLURM version 1.2 and newer</b></li>
<ul>
<li>Consumable resources has been enhanced with several new resources
--namely CPU (same as in previous version), Socket, Core, Memory
