This publication provides information about tuning application programs
on the SGI Altix 3000 and SGI Altix 4000 families of servers and superclusters
running the Linux operating system. Application programs includes Fortran
and C programs written with the Intel-provided compilers on SGI Linux
systems.
This document does not include information about configuring or
tuning your system. For details about those topics, see the
Linux Configuration and Operations Guide.
This guide is written for experienced programmers, familiar with
Linux commands and with either the C or Fortran programming languages.
The focus in this document is on achieving the highest possible performance
by exploiting the features of your SGI Altix system. The material assumes
that you know the basics of software engineering and that you are familiar
with standard methods and data structures. If you are new to programming
or software design, this guide will not be of use
to you.

You can obtain SGI documentation as follows: See the SGI Technical Publications Library at http://docs.sgi.com. Various formats are available. This library contains the most recent and most comprehensive set of online books, release notes, man pages, and other information.
If it is installed on your SGI system, you can use InfoSearch, an online tool that provides a more limited set of online books, release notes, and man pages. With an IRIX system, enter infosearch at a command line or select Help -> InfoSearch from the Toolchest.
On IRIX systems, you can view release notes by entering either grelnotes or relnotes at a command line.
On Linux systems, you can view release notes on your system
by accessing the README.txt file for the product.
This is usually located in the /usr/share/doc/productname directory,
although file locations may vary.
You can view man pages by typing man title at a command line.
