Numerical simulations of astrophysical problems on massively parallel supercomputer

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry “to ascertain the nature of the heavenly bodies, rather than their positions or motions in space”. We describe new version of our AstroPhi code for simulation of astrophysical objects dynamics and other physical processes on hybrid supercomputers equipped with Intel Xeon Phi accelerators. New version of AstroPhi code was rewritten in accordance to co-design technique. It means that we use latest knowledge about last Intel Xeon Phi generation during code development. The results of simulation by means AstroPhi code for Intel Xeon Phi based massive parallel supercomputer are presented in this paper. The RSC PetaStream architecture is used for astrophysical problems simulation in high resolution. The are some galaxies collision with chemodynamics problems and spiral galaxy formation tests are presented as a demonstration of AstroPhi code.
