Abstract

This chapter describes a comprehensive computer technology of numerical modeling of astrophysical flows on hybrid supercomputer equipped with computations accelerators (NVIDIA and/or Intel accelerators). The design of parallel computing algorithms for modeling the gas-dynamic, magnetic gas dynamic, collisionless component of astrophysical objects with consideration of chemical processes is presented. There are three software packages described in this chapter: GPUPEGAS code designed for simulation of astrophysics objects on hybrid supercomputers; AstroPhi code which is used for the dynamics of stars and molecular clouds simulation on hybrid supercomputers equipped with Intel Xeon Phi accelerators; PADME code for simulation of planetary systems formation on hybrid supercomputers.
