Parallel computing in problems that occur during mathematical simulation of radiation transfer

Possibilities of the application of parallel computing to solving problems that occur during mathematical simulation of radiation transfer are considered. Techniques of the radiation analytic representation method (RARM) and the Lagrange-Chebyshev polynomial method (LCPM) for radiation transfer numerical simulation in the nonuniform plane layer of finite thickness that contains single-or multicomponent mixture of substances are designed. The techniques include several sequential and parallel algorithms and programs that realize them; a part of them is joined into a program system with the user interface. Parallel programs are elaborated in MPI and DVM technologies of parallel programming.
