>From your requirements I gather that you want to run a program 1 within which
you want to invoke program2, and program 2 has to run on four nodes.
You will have to use MPI_Comm_spawn for that. You will start with your first
program 1 as a normal MPI program with "mpirun" and make it to run on only one
node. Then within this program you will have to do a MPI_Comm_spawn to run
program 2 on 4 nodes (the number of nodes supplied as a parameter to
MPI_Comm_spawn)
You can read the man page of MPI_Comm_spawn for more information.
Hope this helps
