Is there such a benchmark that I can refer to? I am increasingly convinced that OpenMP/pthread is required only in extreme cases, but I need some numbers to prove that (to myself and my advisor).
Like most other cases YMMV, significantly. That is there is no way to say that one is better than the other except for a very particular situation. This is exacerbated by the fact that different MPI implementations handle communication between processes on the same CPU differently, and some vary further by the choices made during ./ configure.
