As George replied, yes, Open MPI does use sockets -- that's in the TCP BTL (BTL
= byte transfer layer, or point-to-point messaging layer for many network
types). Open MPI also uses shared memory for on-server communication. But
Open MPI can also use lots of other network types, if they're avai
Some questions are easier than others …

When Open MPI is using TCP it does indeed use sockets.

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.

Note that according to http://www.ohloh.net/p/openmpi, OMPI is over 3/4M lines
of code. 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 k

I am an newbie to all MPI concepts and I would like to understand the MPI

framework and module
works. It would be really helpful if wise people could point me to right
direction.
Thanks,
