I wanted to ask some questions about things I am having trouble understanding.
1. As far as my understanding of MPI_INIT function, I assumed MPI_INIT typically procedure resources required including the sockets. But now as I understand from the documentation that openMPI only allocated socket when the process has to send a message to a peer. If some one could let me where exactly in the code this is happening I would appreciate a lot. I guess this is happening in ORTE layer so I am spending time looking at it. But if some one could let me in which function this is happening it will help me a lot.
2. Also I think most of the MPI implementation embed source and destination address with the communication protocol. Am I right to assume openMPI does the same thing. Is this also happening in the ORTE layer.
Is there a documentation about this openMPI site? if there can someone please let me know the location of it.
