MPI_CART_SUB(comm, remain_dims, newcomm)
[ IN comm] communicator with cartesian structure (handle)
[ IN remain_dims] the ith entry of remain_dims specifies whether the
ith dimension is kept in the subgrid ( true) or is dropped ( false) (logical vector)
[ OUT newcomm] communicator containing the subgrid that includes the calling process (handle)
