B Installing Standard LSF on a Subset of Nodes
This document provides instructions for installing standard LSF on a subset of nodes in the HP
XC system; another subset of nodes runs LSF-HPC with SLURM.
This situation is useful for an HP XC system that is comprised of two different types of nodes,
for example, a set of large SMP nodes (“fat” nodes) running LSF-HPC with SLURM and a set of
“thin” nodes running Standard LSF, as Figure B-1 shows.
Figure B-1 Installing Standard LSF on Node Subset
This approach prevents jobs from running across both thin and fat nodes, but does offer full
Standard LSF support for these large SMP systems, particularly job scheduling based on the size
and load of memory, cpu, or both.
The HP XC cluster_config program allows you to decide which nodes have a compute role
and which nodes have a resource management role. The compute nodes become SLURM
compute nodes. The SLURM master and backup daemons reside on the resource management
nodes; one of them is selected to run the LSF-HPC with SLURM daemons. The existing technology
in HP XC allows you to "configure out" a subset of HP XC nodes that will not run LSF-HPC with
SLURM with SLURM.
Before running the cluster_config command to adjust the role assignments, you need to
install Standard LSF and perform some additional configuration to support Standard LSF within
the HP XC system.
Installing Standard LSF on HP XC is straightforward. It just involves a few extra adjustments to
work with the HP XC file system management. The following procedures cover all the necessary
adjustments:
B.1 Requirements
• The Standard LSF version must be the latest version, 6.2 or later (with schmod_slurm
module)
• You must be familiar with Standard LSF installation and administration procedures
• You must be familiar with the procedures for installing and configuring LSF-HPC with
SLURM for SLURM on the HP XC system
• The HP XC head node cannot be configured to run Standard LSF. There is an unresolved
issue in the LSF failover and setup mechanism on the HP XC system that will be corrected
in a future release.
