It would be good to know if that extra time is spent inside MPI calls or
not. There is a discussion of how you might do this here:

Hi OpenMPI folks,
Using the version 1.4.3 of OpenMPI, I wanna to wrap the 'ssh' calls,
which are made from the OpenMPIs 'mpiexec'. For this purpose, at least
two ways seem to be possible for me:
1. let the wrapper have the name 'ssh' and paste the path where it is
into the PATH envvar *befor

I wonder if someone might have possible ideas to explore as to why this
program might not be working correctly under TotalView. Essentially a
user is running a very simple hello world like program that does this:
#include

I can't quite parse your output.
paddress.c should be a sym link in ompi/mpi/c/profile back to
ompi/mpi/c/address.c. I'm not sure why "ls paddress.c" shows a whole directory
of files...?
You might want to whack your OMPI source tree, re-expand the tarball, and try
again. If it still fails, p
