The paper describes parallelization methods used for developing parallel program implementing Eulerian-Lagrangian technique for numerical solution of 3D time-dependent problems of gas dynamics with heat conduction on the grids of modular-matrix type. Two fundamentally different approaches to arranging array-parallel computations were developed.

       Parallelization efficiency has been numerically studied for various methods of a problem geometrical decomposition, for two modes of processor load and depending on the relation between arithmetic and communication work.

       Parallelization efficiency of the parallel program developed is presented for different high-parallel computer systems.
