About This Book This book describes how to use the TotalView® debugger, a source- and machine-level debugger for multi-process, multi-threaded programs. The information in this book assumes that you are familiar with programming languages, a UNIX or Linux operating system, and the processor architecture of the system on which you are running TotalView and your program. This user guide combines information for all TotalView debuggers, whether they run within a Graphic User Interface (GUI) or in an xterm-like window where you must type commands. That version of TotalView is called the Command Line Interface (CLI). This book emphasizes the GUI interface, as it is easier to use. After you see what you can do using the GUI, you will know what you can do using the CLI. TotalView doesn’t change much from platform to platform. Differences between platforms are mentioned. TotalView Family Differences This manual describes TotalView Enterprise, TotalView Team, and TotalView Individual. Each of these allows you to use the CLI debugger as well. In all cases, TotalView Enterprise and TotalView Team have the same features. They differ in they way they are licensed. However, TotalView Individual is slightly different. The most fundamental differences between TotalView Team and TotalView Enterprise are the way resources are shared and used. When you purchase TotalView Team, you are purchasing “tokens.” These tokens represent debugging capabilities. For example, if you TotalView Users Guide: version 8.7 xxiii
