TotalView interprets the changes that the OpenMP compiler makes to your code so that it can display your program in a coherent way. Here are some things you should know:
|
The compiler can generate multiple outlined routines from a single parallel region. This means that a single line of source code can generate multiple blocks of machine code inside different functions.
|
|
|
You can’t single step into or out of a parallel region. Instead, set a breakpoint inside the parallel region and let the process run to it. After execution reaches the parallel region, you can single step in it.

|
OpenMP programs are multi-threaded programs, so the rules for debugging multi-threaded programs apply.

Figure 94 shows a sample OpenMP debugging session.
