MPI_Dims_create is a convenience function that can be used to automatically distribute MPI processes along a certain number of dimensions. When a user learns the basics about topologies, such as MPI_Cart_create, they are unlikely to know about MPI_Dims_create. Linking it in topology functions could therefore be useful.
