Abstract
In this paper we present the AstroPhi code for numerical simulation of astrophysical flows at Intel Xeon Phi supercomputers. The co-design of a computational astrophysics model is described. The parallel implementation and scalability tests of the AstroPhi code are presented. The results of simulation of interaction between intergalactic wind and a disk galaxy are provided. For AstroPhi code a 134x speed-up with one Intel Xeon Phi accelerator and 75% weak scaling efficiency on 224x Intel Xeon Phi accelerators was obtained. We obtained the peak performance on a 7168 × 1024 × 1024 mesh size using 53760 RSC PetaStream threads.
