| Regular grid in 4D space-time - domain decomposition |
| Update algorithm identical at each point |
| Time evolution very simple |
| The world looked at microscopically in terms of a set of similar fundamental quantities |
| Monte Carlo - subtlety that cannot update concurrently points linked in Hamiltonian |
