NextGen TotalView for HPC User Guide : PART II Debugging Tools and Tasks : Chapter 5 Setting and Managing Action Points (Breakpoints) : Breakpoints : Setting Breakpoints When Using the fork()/execve() Functions : Debugging Processes That Call the fork() Function
Debugging Processes That Call the fork() Function
By default, TotalView places breakpoints in all processes in a share group. (See "Share Groups".) When any process in the share group reaches a breakpoint, TotalView stops all processes in the control group. This means that TotalView stops the control group that contains the share group. This control can contain more than one share group.
To override these defaults, modify the breakpoint’s width in the action point’s properties, Modify Breakpoint dialog box.
