Astrophysics Simulation on RSC Massively Parallel Architecture

Abstract

AstroPhi code is designed for simulation of astrophysical objects dynamics on hybrid supercomputers equipped with Intel Xenon Phi computation accelerators. New RSC PetaStream massively parallel architecture used for simulation. The results of AstroPhi acceleration for Intel Xeon Phi native and offload execution modes are presented in this paper. RSC PetaStream architecture gives possibility of astrophysical problems simulation in high resolution. AGNES simulation tool was used for scalability simulation of AstroPhi code. The are some gravitational collapse problems presented as demonstration of AstroPhi code.
