Abstract. The author develops algorithms of parallel realization of the mathematical model of forest fires to model processes of their occurrence, development, and propagation taking into account physical and chemical processes. The approaches of parallel realization and schemes of the decomposition of decision domain for two-dimensional cases are proposed. Coarse-grained parallelization methods are proposed to be used in the SPMD-model of calculations. The formulas that allow making theoretical estimations of the efficiency of parallel programs are presented.

Keywords: parallel implementation, principle, mathematical model, forest fire, supercomputer.
