If you make any changes, be sure to run the scontrol reconfigure command to update
SLURM with these new settings.
15.2.5 Configuring SLURM Features
A standard element of SLURM is the ability to configure and subsequently use a feature. You can
use features to assign characteristics to nodes to manage multiple node types.
SLURM features are specified in the slurm.conf file. After SLURM is updated with the new
configuration, a user can specify the --constraint option so that a job employs those features.
“Using a SLURM Feature to Manage Multiple Node Types” (page 176) shows how to configure
SLURM feature to differentiate node types, update the configuration, and launch a sample
command. The following provides background information on this example.
The HP XC system, xmp, contains 98 nodes:
xmp[1-64]
Two single-core processors per nodeCompute nodes
xmp[65-96]
Two dual-core processors per nodeCompute nodes
xmp[97,98]
Two dual-core processors per nodeService nodes
These nodes were initially configured as follows in the slurm.conf file:
NodeName=xmp[1-64] Procs=2
NodeName=xmp[65-98] Procs=4
Example 15-1 configures the compute nodes into two separate groups: single and dual. The
two service nodes are configured into their own group.
