Abstract We propose a new code named AstroPhi for simulation of the dynamics of astrophysical objects on hybrid supercomputers equipped with Intel Xenon Phi computation accelerators. The details of parallel implementation are described, as well as changes to the computational algorithm that facilitate efficient parallel implementation. A single Xeon Phi accelerator yielded 27-fold acceleration. The use of 32 Xeon Phi accelerators resulted in 94% parallel efficiency. Several collapse problems are... Title of program: AstroPhi Catalogue Id: AEUM_v1_0 Nature of problem Complex numerical simulation of dynamics of astrophysical objects plays an important role due to significant growth of observational astronomic data. The new astrophysical models and codes need to be developed for detailed simulation of different physical effects in astrophysics with the use of modern supercomputers with hybrid architecture.
