This paper presents a new approach that enhances the performance of large scale cellular space simulations expressed in modular DEVS. The basic idea is to group cells in cellular space into smaller partitions that are treated as atomic DEVS models. The enhancement is achieved by reducing the large number of messages generated by inter- cell communication. This, in turn, saves large number of simulator iterations that were used to handle such communication. The new approach gives significant simulation speedup over the conventional techniques of representing cells in DEVS. A landslide slope criticality model is used to perform some computational experiments to demonstrate the simulation speedup of our approach.
