Subject: [OMPI devel] Modex and others

Hi All,

I understand that a process need to have the contact information to send
MPI messages to other processes, and modex permits it. My question is,
why do not perform the contact exchange when it is necessary?

For example: in a M/W application, the workers does not need more
information than the masters contact info.

I think that it reduces the startup time, but increases the *first*
communication between two peers.
