This appendix describes how to join an HP XC system
running LSF-HPC with SLURM (integrated with the SLURM resource manager) to
an existing standard LSF Cluster without destroying
existing LSF-HPC with SLURM configuration. After installation, the HP XC system
is treated as one host in the overall LSF cluster, that is, it becomes
a cluster within the LSF cluster. Figure A-1 depicts an HP XC node running Standard
LSF connected by one wire to the nodes in the site LSF Cluster.
An existing LSF cluster typically has a single
common LSF_TOP location, also known as the "LSF
root" or LSF "tree". Multiple versions of LSF are installed and centrally
maintained at the LSF_TOP location. Note that LSF_TOP is not an actual environment variable created by
LSF, it is just used to denote the LSF "root" in the documentation.
The procedures in this appendix installs LSF-HPC with SLURM into
the LSF_TOP location on the existing LSF cluster.
This installation retains the functionality currently
used by the existing Standard LSF cluster, while providing the SLURM
support needed by the HP XC cluster.
This appendix consists of the following sections
that correspond to the major tasks for installing the cluster:
