THE PROBLEMS OF MODERN SUPERCOMPUTER APPLICATIONS IN HYDRODYNAMIC AND AEROACOUSTIC NUMERICAL SIMULATIONS
ABSTRACT
Considered in this article are various aspects associated with the implementation of large-scale supercomputer calculations of hydrodynamic and aeroacoustic problems; the problems of computational optimization are considered. Given are the means of achievement of high parallel efficiency for a large number of processors (up to several thousand). The implementation features of architecturally adapted hybrid paralleling, the optimization of memory access, and parallel processing of computational data and large grids are described. Given here are examples of direct numerical simulation applications for the simulation of both compressible and incompressible turbulent flows with the use of high-accuracy numerical algorithms on structured and unstructured grids.
