FleCSPHg: A GPU Accelerated Framework for Physics and Astrophysics Simulations
2018
This paper presents FleCSPHg, a GPU accelerated framework dedicated to Smoothed Particle Hydrodynamics (SPH) and gravitation (FMM) computation. Astrophysical simulations, with the case of binary neutron stars coalescence, are used as test cases. In this context we show the efficiency of the tree data structure in two conditions. The first for near-neighbors search with SPH and the second with N-body algorithm for the gravitation computation.
