Totalview® for HPC User Guide : PART IV Advanced Tools and Customization : Chapter 20 Setting Up Parallel Debugging Sessions : Debugging OpenMP Applications : Viewing the OpenMP Stack Parent Token Line
Viewing the OpenMP Stack Parent Token Line
TotalView inserts a special stack parent token line in the Stack Trace Pane of OpenMP worker threads when they are stopped in an outlined routine.
When you select or dive on the stack parent token line, the Process Window switches to the OpenMP master thread, allowing you to see the stack context of the OpenMP worker thread’s routine.
