We describe in this paper a distributed model and the techniques we used for implementing such a simulation on a cluster of workstations. The need in adapted methodologies in this area is a recurrent problem. Simulation times obtained do not allow developping effective prediction tools. Realistic large-scale simulations are obtained to the detriment of precision and simulation time. This is due to the physical models increasing complexity which is in constant opposition with the available computing resources. We show that an OpenMOSIX cluster could form a basis for a good distributed engine, easily adaptable for spatial model in large-scale simulations.
