The Hitchhiker's Guide to the Galaxy begins with Arthur Dent, earthman and main character, being suddenly swept aboard an alien spaceship from his garden. Once on the ship, his new surroundings bewilder Arthur totally. Fortunately, Ford Prefect, Arthur's earth companion (who, as Arthur recently discovered, is actually an alien from a planet somewhere in the vicinity of Betelguese), is there to explain what's going on.
Just as Arthur had to get used to his new environment when he first left earth, this chapter will help you get used to the new environment you're in; the IBM Parallel Environment for AIX (PE). It covers:
This book contains many examples and illustrates various commands and programs as well as the output you get as a result of running them. When looking at these examples, keep in mind that the output you see on your system may not exactly match what's printed in the book. This is due to the differences between your system and ours. We've included the examples here just to give you a basic idea of what happens.
The IBM RS/6000(R) World Wide Web site (as described in Accessing PE documentation online), provides the sample programs, as they appear in this book, in source format. If you intend to write or use any of the sample programs, you should obtain the examples from the web site rather than copying them from the book. Because of formatting and other restrictions in publishing code examples, some of what you see here may not be syntactically correct. On the other hand, the source code on the web site will work (we paid big bucks to someone to make sure they did).
If you're unfamiliar with the terms in this chapter, the Glossary may be of some help.
