摘要：
In this paper, we propose the last version of the numerical model for simulation of astrophysical objects dynamics, and a new realization of our AstroPhi code for Intel Xeon Phi based RSC PetaStream supercomputers. The co -design of a computational model for the description of astrophysical objects is described. The parallel implementation and scalabi.lity tests of the AstroPhi code are presented. We achieve a 73% weak scaling efficiency with using of 256x Intel Xeon Phi accelerators with 61440 threads.
