title: Seeing the code being executed for an MPI program
body: <p>I want to step through and SEE the code that is being executed in an <code>MPI</code> program. For example if <code>MPI_Init()</code> is being executed then I should be able to SEE what code is actually being executed - like going into the <em>mpi.h</em> file and seeing statements there, maybe going into another <em>xyz.c</em> file and seeing the part of the code being executed there. This is analogous to the <em>F7</em> key we had with <em>Turbo C++</em> which helped us to see and execute one line at a time. Is <em>TotalView</em> a software which lets us do this ? Thanks. </p>
