You have to use MPI's lookup function (MPI_LOOKUP_NAME) -- you cannot
supply your own name. Specifically, the name that you publish/lookup
is your name -- it can be whatever you want. The name that is returned
by OPEN_PORT and LOOKUP_NAME is a system-defined name -- you can't
choose what it will be (and it may be different in each run).
It looks like you are using MPICH, however. You should probably direct
MPICH-related questions to their discussion list.
Good luck!
