Grouping by Status and Source Line
If you select the Thread State, leaving Source Line also selected, you can group by both properties, as in Figure 66.
 
Figure 66 – Root Window: Grouped by Status and Source Line
Again, there are two groupings in the list: the first is the mpirun process. Note that the second grouping is now multi-line:
The first line of the second grouping displays a single thread, showing both that its status is at Breakpoint and that it is at line 100 in tx_basic_mpi.c.
The second line displays 31 threads, all at a different Breakpoint at line 112 in tx_basic_mpi.c.
