Numerical simulation of the continuous media problems on hybrid computer systems
The paper presents some results of modeling continuous media problems on computer system with hybrid architecture on the base of Quasi Gas Dynamic (QGD) equations system. The successful experience in solving a wide variety of gas dynamic problems by means of QGD based schemes showed that they describe viscous heat conducting flows as good as schemes for NavierStokes equations, where the latter are applicable. The explicit scheme described here has a Courant stability condition even for very low Mach numbers. So, it is very convenient for computer systems with the hybrid architecture, in particular for GPU-based computers. Parallel realization is based on shmem programming technology. The calculations results show good parallelization efficiency.
