The notes
in this section apply to the Simple Linux Utility for Resource Management
(SLURM). SLURM provides commands for launching, monitoring, and controlling
jobs.
Refer to the HP XC System Software User's Guide for more information about
using SLURM.
Error in slurm.epilog.clean Script |
 |
SLURM
provides a slurm.epilog.clean script in the /opt/hptc/slurm/etc/ directory. This script is not used
in normal operation by default. However, it is provided if you want
to configure SLURM on your XC system to ensure that all processes
relating to a user's job on the compute nodes are terminated
after the job has completed.
An error has been discovered in this script where
the SLURM_BIN variable is not set. If this script
is enabled, this error causes the script to terminate all user processes
on the node, even if the user has a separate job running on the same
node.
Follow this procedure to correct the problem:
On the head node, use the
text editor of your choice to edit the following file:
/opt/hptc/slurm/etc/slurm.epilog.clean |
Add the following line to
the file:
SLURM_BIN=/opt/hptc/slurm/bin
|
Save your changes and exit
the file.
Use procedures in the HP XC System Software Administration Guide to
update the golden image and propagate the new image to all nodes.
How to Remove SLURM |
|
The HP XC system installation process offers a choice of two different
types of LSF. The default choice, LSF-HPC with SLURM, requires that
SLURM is also installed and configured. The other choice is standard
LSF, which does not require nor interact with SLURM. If standard LSF
is selected, SLURM should not be configured.
If SLURM has been installed and configured but
is not required, use the following procedures to deactivate it:
As root on the head node, shut down SLURM:
Unconfigure SLURM on the head node:
# /opt/hptc/slurm/etc/gconfig.d/slurm_gconfig.pl gunconfigure
# /opt/hptc/slurm/etc/nconfig.d/slurm_nconfig.pl nunconfigure |
Update the golden image.
Propagate the new golden image to all nodes.
