I am not sure I fully understand your question, I have 2 possible
interpretations.
If your question is:
"can we see somewhere that process X is doing an MPI call which is being
'executed' by process Y?" :
To my knowledge, Valgrind can't show this but I might be very wrong
(I do have only a ultra basic theoretical knowledge of MPI).
Now, if your question is:
"when running under Valgrind, can you see a backtrace/stacktrace of the
function calls that lead to a MPI call like with gdb ?"
then you could try the last Valgrind svn version. A gdbserver has been
integrated in Valgrind.
The gdbserver allows to debug your executable under Valgrind using the
normal gdb commands (break, next, backtrace, ...).

Can we see the runtime call Hierarchy of MPI program. Like we do
debugging by gdb. How can I see that ?
