Numerical simulation of hydrodynamics instabilities evolution on multiprocessor systems

An effective three-dimensional parallel algorithm using a combination of MPI and OpenMP for numerical simulation of hydrodynamic instabilities evolution on the basis of schemes of high order on multiprocessor systems with hybrid architecture has been proposed. A research of the combined techniques of parallelization in comparison with pure MPI is produced. Using the realized numerical algorithm the calculations of two typical problems of hydrodynamic instabilities evolution (Richtmyer-Meshkov and Rayleigh-Taylor) has been produced. For the problem of Rayleigh-Taylor instability a clear Kolmogorov spectrum is received.
