I know that its a huge code base. But, I am looking for specific answers like does OpenMPI use sockets? Can programs written without mpi libraries be run on
clusters using orte(with some changes)? It would be really helpful if atleast these and related doubts can be solved.

I doubt you will be able to get a thorough understanding of *all* of OMPI in a semester or two -- indeed, I doubt that any one Open MPI core developer has a thorough understanding of the whole code base (I know I don't!).
