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.
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 and a set of “thin” nodes running Standard LSF, as Figure B-1 shows.
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 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.
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:
