Parallel implementation of a cellular automaton model for the simulation of laser dynamics

A parallel implementation for distributed-memory MIMD systems of a 2D discrete model of laser dynamics based on cellular au- tomata is presented. The model has been implemented on a PC cluster using a message passing library. A good performance has been obtained, allowing us to run realistic simulations of laser systems in clusters of workstations, which could not be a orded on an individual machine due to the extensive runtime and memory size needed.
