Crop simulation modelling using a transputer-based parallel computer

Abstract The adaptation of a biological model of the growth and development of wheat is described that allows simulations to be carried out concurrently. The number of simulations that can be carried out side-by-side is limited only by the number of transputers available to the user. The use of this version of CERES-Wheat is illustrated with reference to a fertiliser experiment, and the speed of execution is compared with other hardware systems. Uses to which a parallel computer could be put in crop simulation modelling are discussed, and further developments are outlined.
