     of two existing groups.  This routine accepts the following parameters:

     group1    Specifies the first group (handle)

     group2    Specifies the second group (handle)

     group_out Returns the intersection group (handle)

     ierror    Specifies the return code value for successful completion,
	       which is in MPI_SUCCESS.	 MPI_SUCCESS is defined in the mpif.h
	       file.
