This paper is devoted to a parallel implementation of multiscale approach to the numerical study of gas flows in microchannels of complex technical systems. The multiscale approach combines the solutions of quasigasdynamic (QGD) equations and molecular dynamics (MD) equations. The proposed parallel implementation of this approach is based on the method of splitting into physical processes and the domain decomposition method. The implementation is oriented for using computer systems with central and hybrid architectures. The developed parallel algorithms show a good scalability. The obtained results confirm the efficiency of the approach under consideration. This approach was used to find the basic coefficient dependences for the QGD system by MD methods and to study a three-dimensional gas flow numerically.
Keywords: gas dynamics, molecular dynamics, parallel algorithms and programs, supercomputing simulation.
