Using Groups, Processes,
and Threads
13
The specifics of how multi-process, multi-threaded programs execute
differ greatly from platform to platform and environment to
environment, but all share some general characteristics. This chapter
discusses the TotalView process/thread model. It also describes
the way in which you tell the GUI and the CLI what processes and
threads to direct a command to.
This chapter contains the following sections:
� “Defining the GOI, POI, and TOI” on page 251
� “Setting a Breakpoint” on page 252
� “Stepping (Part I)” on page 253
� “Using P/T Set Controls” on page 256
� “Setting Process and Thread Focus” on page 257
� “Setting Group Focus” on page 262
� “Stepping (Part II): Examples” on page 273
� “Using P/T Set Operators” on page 275
� “Creating Custom Groups” on page 276
Defining the GOI, POI, and TOI
This chapter consistently uses the following three related acronyms:
� GOI—Group of Interest
� POI—Process of Interest
� TOI—Thread of Interest
These terms are important in the TotalView process/thread model because
TotalView must determine the scope of what it does when it executes a
command. For example, Chapter 2, “About Threads, Processes, and Groups”
