If you have money to spend you should look at TotalView (http:// 
www.totalviewtech.com), (maybe even if you don't think you have money  
to spend it may be worth looking; after all, how much do you value  
your time?).

It certainly has a lot of MPI support (I worked there for ten years  
and did a large part of the implementation of MPI support , so I'm  
not entirely neutral on this :-).

I'm not sure what free (as in beer) solutions there are, though as  
part of getting TotalView working well with MPI Bill Gropp and I  
published a paper (http://citeseer.ist.psu.edu/368538.html) on how to  
implement MPI debugging, so there's nothing to stop people who have  
an itch from scratching it.
