HP XC System Software Administration Guide Version 3.1

This directory is mounted on the head node. You must ensure the persistence of this file system mount.
Caution:
Do not add, replace, or remove any files in the /hptc_cluster directory. Doing so will cause the HP
XC system to fail.
1.2.1.2 HP XC System Software Directory, /opt/hptc
The HP XC System Software maintains the /opt/hptc directory for its exclusive use. Its software is
installed in that directory.
Do not install or replace any other software in this directory unless it is an officially supported patch.
Software packages, such as the SLURM resource manager, are installed in directories under the /opt/hptc
directory under their own names.
Caution:
Avoid adding, replacing, or removing any files in the /opt/hptc directory, unless you are directed to
do so. Missing or corrupted files can cause the HP XC system to fail.
Software packages under the /opt/hptc directory have their own subdirectories, usually bin, etc, sbin
and presumably others). There are symbolic links to files in these subdirectories (for example,
/opt/hptc/package/bin) to the corresponding directory (for example, /opt/hptc/bin).
The SLURM resource manager is such a package; its structure in the /opt/hptc directory structure is
illustrated in Figure 1-2; the SLURM directory and its subdirectories are shown as dashed line boxes. The
SLURM package has its own bin, etc, lib, and sbin, subdirectories. Each executable in the
/opt/hptc/slurm/bin directory has a symbolic link to the /opt/hptc/bin directory. Likewise, there
are symbolic links in the other SLURM subdirectories.
