When you’re debugging message-passing and other multi-process programs, it is usually easier to understand the program’s behavior if you change the default stopping action of breakpoints and barrier breakpoints. By default, when one process in a multi-process program hits a breakpoint, TotalView stops all other processes.

To change the default stopping action of breakpoints and barrier breakpoints, you can set debugger preferences. The online Help contains information on these preference. These preferences tell TotalView whether to continue to run when a process or thread hits the breakpoint.

These options affect only the default behavior. You can choose a behavior for a breakpoint by setting the breakpoint properties in the File > Preferences Action Points Page. See “Setting Breakpoints for Multiple Processes”.
