The problem of constructing the maximum parallel forms of difference algorithms to solve applied problems of metallurgical thermal physics is investigated. The features of parallelization by piecewise-analytical method of lines and method of permutations are revealed. The proposed approach does not impose any restrictions on the grid nodes topology of the computational domain. In addition, with regard to the parallel computation of arithmetic expressions, it separates the error of initial data from the rounding operations inherent in classical methods. It is shown that the constructed parallel form of the algorithm is maximum, and, therefore, has the minimum possible implementation time when using parallel computing systems. |
