The MPI publish/lookup calls should handle this, if OpenMPI has them. I
haven't tried this with OpenMPI yet, but it claims MPI-2 compilance,
right? ;-)

Hello,
Is there a way of providing a specific port number in MPI_Info
when using a MPI_Open_port command so that clients know which
port number to connect.
the MPI port-name in Open MPI has nothing to do with a TCP port
number. The port-name right now is a combination of the process
name ( a tuple of cell id, job id and process id) and a tag used
for the communication.
Maybe somebody from the RTE group could comment on whether there is
a possibility to specify a specific port number for OOB
communication, I am not aware of any right now...
I'm afraid not - the port number for OOB communications is determined
dynamically be each process, and then communicated between them.
I'm not sure what your intended purpose is here, of course, but you
don't need to worry about your process being able to "talk" via the
OOB - it's all done automatically during launch.

Thanks Edgar
Do advice of any solution so that we can create the portname
inside the client once we know the port number of server.
Thanks Abhishek
