The MPI_Barrier call in the parent must be on the intercomm returned by the
spawn. The call in the children must be on MPI_COMM_PARENT.
The semantic of an MPI_Barrier call on an intercomm is:
No MPI_Barrier caller in the local group returns until all members of the
remote group have m
not wait for each other with the following commands:
CALL MPI_BARRIER(MPI_COMM_WORLD,ierr) ! in parent
CALL MPI_BARRIER(MPI_COMM_WORLD,ierr) ! in child

eventually be solved, step-by-step.
