HP XC System Software Installation Guide Version 3.1

HP recommends that you install additional software components now before the system is configured
(the procedure described in Chapter 3 (page 43)) so that the software is propagated to all nodes during
the initial image synchronization.
This chapter does not contain product-specific information for third-party software products; see the
documentation supplied by the vendor for product-specific information.
The following sources contain more information about optional software products that are available for
use with HP XC systems:
• HP XC System Software QuickSpecs
The HP XC System Software QuickSpecs contain a list of commercially available software packages
that have been tested and qualified to interoperate with the HP XC System Software. If you want to
learn more about these supported software packages, see the QuickSpecs at:

• HP XC Program Development Environment Site
The following HP Web site provides pointers to tools that have been tested in the HP XC program
development environment (for example, the TotalView debugger, other debuggers, Intel and PGI
compilers, and so on):

2.5.3 Install Compilers
The XC software does not bundle or resell Intel or PGI compilers. You are responsible for purchasing and
licensing them from the third-party vendors. There may be run-time licensing issues (for running the
resulting applications) separate from licensing the compiler itself.
You can install additional compilers on HP XC systems, such as those from Intel or PGI, after the initial
system installation by using the installation instructions supplied by their kits and by distributing the
software to all nodes as described in the HP XC System Software Administration Guide, so that the supplied
libraries are visible to distributed applications.
During the compiler installation process, use the default locations suggested by the installation process,
if possible. If you change the installation directory and modules are being used, you must edit the
corresponding modulefile to point to their new location or create a corresponding symbolic link. Modulefiles
are located in the /opt/module/modulefiles directory.
In some cases, it might be desirable to install the compiler in other than the default installation location,
for example:
• In a new default location
• As a sibling compiler in a different location
• In a revision-specific or date-specific directory
Go to the following Web sites for more information about the supported compilers:
• Intel compilers

• The Portland Group, supplier of the C/C++ and Fortran compilers

2.6 You Are Done
You have completed the installation of the HP XC System Software and locally available optional software
on the head node.
Proceed to Chapter 3 to configure the system topology, set up the system environment, start system
services, and synchronize the system image across all nodes.
