I'm not sure I understand your question. Do you want the processes in
one job to talk to the processes in the other job? Or for the
processes to be able to communicate within the same job, but at the
same time? If the first, you want to look at the MPI-2 connect/accept
dynamic process management. If the second, everything should "just
work", so you shouldn't have any problems.
Of course, if I misunderstood your question completely, please include
some more detail.
