HP XC System Software Administration Guide Version 3.2.1

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.
