That's weird. I compiled on Snow Leopard (but with gcc) and it works fine for me. Open MPI definitely defines MPI_SUM on MPI_DOUBLE.

I don't have the intel compiler to test with on Snow Leopard, unfortunately... It works fine for me with the intel suite 11.1.072 on Linux RHEL 5.

I'm afraid I have no way to testing further -- is there any chance you can step through and see what is going on?
