Operation and Use, Volume 2

How this book is organized

This book contains the following information:

• Chapter 1, Using the pdbx debugger describes the Parallel Environment's command line debugger - pdbx. This tool uses a line-oriented interface, allowing you to invoke a parallel program from an ASCII terminal.
• Chapter 2, Profiling parallel programs with Xprofiler describes how to profile your programs with the Parallel Environment's Xprofiler.
• Chapter 3, Analyzing program performance using the PE Benchmarker toolset describes the various tools in the PE Benchmarker toolset. You can use these tools for collecting and analyzing program event trace or hardware performance data.
• Appendix A, Parallel environment tools commands contains the manual pages for the PE commands discussed throughout this book.
• Appendix B, Command line flags for normal or attach mode shows the command line flags for pdbx debugging in normal or attach mode.
• Appendix C, Customizing Xprofiler resources describes how to customize X-Windows resources for PE tools.
• Appendix D, Profiling programs with the AIX prof and gprof commands describes how to use the AIX profilers prof and gprof to profile parallel programs.
• Appendix E, Understanding and Creating PCT Hardware Counter Groups describes the pre-defined hardware counter groups we have defined for the Performance Collection Tool (part of the PE Benchmarker toolset). This appendix also describes how you can create your own hardware counter groups.
