MPI within SMP machines question

With MPI, messages are passing over network in typical beowulf
environment. My question is, when src and dst are two processes
running on the same machine, does it still communicate through
network? or something smarter way like shared memory? or this
is a feature I can explicitly enable? Thank you for your reply.
