This book provides suggestions and guidance for using the IBM Parallel Environment for AIX program product, version 2.4.0, to develop and run Fortran and C parallel applications. To make this book a little easier to read, the name IBM Parallel Environment for AIX has been abbreviated to PE throughout.
In this book, you will find information on basic parallel programming concepts and the Message Passing Interface (MPI) standard. You will also find information about the application development tools that are provided by PE such as the Parallel Operating Environment, Visualization Tool, and Parallel Debugger.
This book has been written with references and allusions to The Hitchhiker's Guide to the Galaxy, by Douglas Adams. If you are not familiar with the book, the basic premise is an all-encompassing guidebook to the entire galaxy. While we don't have such grandiose aspirations for this book, we do expect it to assist you in finding your way around the IBM Parallel Environment for AIX.
