valgrind 3.4 meaning the trunk?

Can you use Open MPI v 1.3? See:
http://www.open-mpi.de/faq/?category=debugging#memchecker_what
Note that 1.3 isn't released, it's only in the repository at this point.

I also use OpenMPI quite frequently, and I haven't quite taken the
dive to check out 1.3 and memchecker... I was given some other ideas
that I still haven't found time to try, first. So, while I'm hoping
this helps you, I'm also trying to use you as a guinea pig to evaluate
that setup <g>
Best,
