Thanks so much Jeff, appreciate your detailed response. I will follow up
with reading the source code for better understanding and get back if I
have further questions.

Hi,
I am trying to understand how connections are established among MPI ranks.
Pardon for the list of questions.
1) Is there a global data structure that creates and stores rank to network
address (uri or port number) mapping
2) How is the location of an MPI rank is determined in point-to-point
