Yaron, I'd recommend you check out TotalView.
It is a mature, established product designed just for what it sounds like you are doing. See our webpage at www.etnus.com. You haven't mentioned what platform you are using but if it is something that TV supports I think you'll find that it is a good solution for problems in a C++ MPI program. A few quick tidbits: We have integration with MPI starter programs. I know that OpenMPI supports this integration, but you might need to update to the latest version and/or rebuild with --enable-debug to take advantage of it. We have great C++ support for a wide range of compilers across a large set of platforms. This includes translation of STL container classes to a nice readable format, support for for your own template classes, nice representation of inheritance, a c++ expression system that lets you call C++ object member functions, etc... We have a cluster architecture that allows us to scale to thousands of processors (though realistically most people debug on the smallest size that will reproduce their problem). I'd be happy to correspond with you offlist if you do decide to evaluate TotalView. Note that you can get a free 15 day evaluation license directly from our website.
