      Parallelization algorithm is studied for 2-D multidomain heat conduction computations on distributed-memory multiprocessors. The algorithm under consideration is implemented with D codes intended for numerical calculations of 2-D and 3-D gas dynamics, heat conduction and elasticity-plasticity in Lagrangian variables on regular grids. The results of parallelization algo-rithm evaluation on 8-processor MP-3 system are presented.

      Тhis work presented the main feature, of the INCH-M method which is an adaptation of the individual particle method m meshes, intended for computing multicomponent media Sows with large scheme of the method proposed has the second order of space and toe approximation with particles symmetrically arranged about Eulerian grid сеlls and is conservative in mass and energy. Computed data for some gas dynamics problems are presented. The computed data are compared with exact solutions, experimetal data and the results of the similar computations using D and EGAK methods.
