HP XC System 4.x Software - Manual (Page 11)

About This Document
This document provides information about using the features and functions of the HP XC System
Software. It describes how the HP XC user and programming environments differ from standard
Linux® system environments. In addition, this manual focuses on building and running
applications in the HP XC environment and is intended to guide an application developer to
take maximum advantage of HP XC features and functions by providing an understanding of
the underlying mechanisms of the HP XC programming environment.
An HP XC system is integrated with several open source software components. Some open source
software components are being used for underlying technology, and their deployment is
transparent. Some open source software components require user-level documentation specific
to HP XC systems, and that kind of information is included in this document, when required.
HP relies on the documentation provided by the open source developers to supply the information
you need to use their product. For links to open source software documentation for products
that are integrated with the HP XC system, see
“Supplementary Software Products” (page 13) .
Documentation for third-party hardware and software components that are supported on the
HP XC system is supplied by the third-party vendor. However, information about the operation
of third-party software is included in this document if the functionality of the third-party
component differs from standard behavior when used in the XC environment. In this case, HP
XC documentation supersedes information supplied by the third-party vendor. For links to
related third-party Web sites, see
“Supplementary Software Products” (page 13) .
Standard Linux® administrative tasks or the functions provided by standard Linux tools and
commands are documented in commercially available Linux reference manuals and on various
Web sites. For more information about obtaining documentation for standard Linux administrative
tasks and associated topics, see the list of Web sites and additional publications provided in
“Related Software Products and Additional Publications” (page 15) .
Intended Audience
This document is intended for experienced Linux users who run applications developed by
others, and for experienced system or application developers who develop, build, and run
application code on an HP XC system.
This document assumes that the user understands, and has experience with, multiprocessor
systems and the Message Passing Interface (MPI), and is familiar with HP XC architecture and
concepts.
