Abstract

This paper describes a parallel simulator for the propagation of a parasite in a vineyard. The model considers the structure, the growth and the susceptibility of the plant which play a major role in the development of the fungus and the spread of epidemic. Two spatial scales are distinguished for the dispersal of the parasite. We use both a realistic discrete model for the local dispersal, and a stochastic model for the long-range dispersal that averages the displacement of spores. An algorithmic description of the parallel simulator is given and real life numerical experiments on IBM SP3 are provided, that use up to 128 processors.
