PARALLEL SIMULATION OF A CELLULAR POLLUTION MODEL

A simple cellular model is used to formulate a three-dimensional air p ollution problem. Its structure allows for a straight forward implemen tation on parallel computers with a minimum of scalar operations and p rovides a superior modeling flexibility with respect to many more trad itional approaches. The results of its implementation on different har dware architectures are presented and show that these models can great ly benefit from the use of array processor machines but that speedups of real studies are orders of magnitude lower than theoretically expec ted.
