[OMPI devel] Detailed documentation on OpenMPI

2013-08-22 Thread mahesh
Hi,
I am an newbie to all MPI concepts and I would like to understand the MPI 
source code thoroughly for
an academic project. So, what I need is an detailed explanation of how every 
framework and module 
works. It would be really helpful if wise people could point me to right 
direction.

Thanks,
Mahesh

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.

Thanks,
Mahesh
