Analyzing Program Performance With Sun WorkShop

Preface

This manual describes the performance and analysis tools available with Sun WorkShop(TM). Developing high performance applications requires a combination of compiler features, libraries of optimized routines, and tools to analyze and isolate code. Analyzing Program Performance With Sun WorkShop describes the third part of this development strategy, and shows you how to use these tools:

The Sampling Analyzer and Sampling CollectorLoopTool and LoopReportLockLintprof, gprof, and tcov

"Related Books" lists sources for information about Sun WorkShop compilers and performance libraries.

Who Should Use This Book

This manual is intended for programmers with a working knowledge of Sun WorkShop and some understanding of the Solaris(TM) operating environment and UNIX\256 commands. Some knowledge of performance analysis is also helpful in understanding how to use the data derived from the tools, but is not required for using them. The traditional profiling tools prof, gprof, and tcov, do not require a working knowledge of Sun WorkShop.

How This Book Is Organized

Chapter 1, "Performance Profiling and Analysis Tools," introduces the performance analysis tools, briefly discussing what they do and when to use them.

Chapter 2, "The Sampling Analysis Tools," describes the Sampling Collector and the Sampling Analyzer. You can use these tools to help you improve your program's use of resources.

Chapter 3, "Loop Analysis Tools," presents LoopReport and LoopTool, which help you analyze program loops that have been parallelized by your compiler.

Chapter 4, "Traditional Profiling Tools," covers the traditional profiling tools prof, gprof, and tcov, which help you find the parts of your program that are most heavily used, and determine how much of your program is being tested.

Chapter 5, "Lock Analysis Tool," documents LockLint, which assists you in analyzing locks and potential race conditions in multi-threaded programs.

Appendix A, "LockLint Command Reference," provides reference-style information on the LockLint commands.

Accessing AnswerBook2 Collections

The Sun WorkShop documentation is also available using AnswerBook2 software. To access the AnswerBook2 collections, your system administrator must have installed the AnswerBook2 documents during the installation process (if the documents are not installed, see your system administrator or Chapter 3 of Sun WorkShop Quick Install for installation instructions). For information about accessing AnswerBook2 documents, see Chapter 6 of Sun WorkShop Quick Install, Solaris installation documentation, or your system administrator.

Note -

To access AnswerBook2 documents, Solaris 2.5.1 users must first download AnswerBook2 documentation server software from a Sun Web page. For more information, see Chapter 6 of Sun WorkShop Quick Install.

Accessing HTML Documents

The following Sun Workshop documents are available online only in HTML format:

To access these HTML documents:

  1. Open the following file through your HTML browser:

    install-directory/SUNWspro/DOC5.0/lib/locale/C/html/index.html

    Replace install-directory with the name of the directory where your Sun WorkShop software is installed (the default is /opt).

    The browser displays an index of the HTML documents for the Sun WorkShop products that are installed.

  2. Open a document in the index by clicking the document's title.
