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.

New and Changed Information in This Edition
