Setting Action Points
In TotalView, breakpoints are called "action points." TotalView has four kinds of action points:
*A breakpoint stops execution of processes and threads that reach it.
*A barrier point synchronizes a set of threads or processes at a location.
*An eval point executes a code fragment when it is reached.
*A watchpoint monitors a location in memory and stops execution when it changes.
This chapter contains the following sections:
*“About Action Points”
*“Setting Breakpoints and Barriers”
*“Defining Eval Points and Conditional Breakpoints”
*“Using Watchpoints”
*“Saving Action Points to a File”
