Preface

This document provides information about how to use KAP Fortran software on OpenVMS Alpha systems.

Intended Audience

This document is a guide for KAP users working with Fortran on OpenVMS Alpha systems.

This document is organized into the following chapters and appendixes:

Chapter 1 provides an introduction to KAP Fortran for OpenVMS Alpha.
Chapter 2 presents information on how to run KAP.
Chapter 3 presents information on how to compile and run programs with KAP on symmetric multiprocessor systems.
Chapter 4 describes the command qualifiers used to alter KAP defaults, such as setting KAP optimization levels and enabling or disabling classes of transformations.
Chapter 5 presents directives to alter KAP defaults. Directives are like command qualifiers, except they appear within a program and may be changed on a loop-by-loop basis.
Chapter 6 specifies KAP assertions that can provide KAP with additional information about the input program that would normally be unknown at compile time.
Chapter 7 provides additional information on subprogram inlining, Interprocedural Analysis (IPA), and the KAP command qualifiers and directives that control them.
Chapter 8 shows examples of the transformations that KAP performs to enhance the code.
Chapter 9 describes the information available in the optional KAP listing and the messages that KAP produces.
Appendix A describes data dependence analysis and explains how KAP uses this information to determine if a given loop can be optimized.
Appendix B lists the diagnostic messages that can appear in the optional annotated program listing.

This document is part of the KAP documentation set that also includes:

Convention	Description
italic type	Italic type indicates complete titles of manuals.
lowercase	Commands are usually presented in lowercase. The KAP command line, however, is not case sensitive.
< >	Angle brackets denote command input you replace with the appropriate value.
( )	Parentheses containing a single command value denote the default value. For example, (/optimize=5) denotes 5 is the default value. Parentheses containing hyphenated value ranges denote that you choose a value from the range.
[ ]	Square brackets denote optional items.
Defaults	Unless specified otherwise, the code examples in this manual were run with the qualifiers /optimize=5, /roundoff=3, /scalaropt=3, and /unroll=1.
