I have read MPI-2 documents as well as FAQ. I am confused as the best way
to establish communication
between two MPI_COMM_WORLD which has been created by two mpiexec calls on
the same node.

mpiexec -conf config1
     This start 20 processes on 7 nodes

mpiexec -conf config2
      This start 18 processes on 5 nodes

I do appreciate any comments or pointer to a document or example.
