Description

The multi-array could provide access to types not directly supported via an interface that looks like this:

subroutine dist_mult_array_get_cache_val_mpidt(dm_array, sub_array_idx, &
       cache_idx, coord, v)
    TYPE(dist_mult_array), INTENT(in) :: dm_array
    INTEGER, INTENT(in) :: sub_array_idx, cache_idx
    INTEGER, INTENT(in) :: coord(:)
    TYPE(C_PTR) :: v

and write to v via MPI_Sendrecv on MPI_Comm_self.
