Towards an efficient multi-stage Riemann solver for nuclear physics simulations

Abstract

Relativistic numerical hydrodynamics is an important tool in high energy nuclear science. However, such simulations are extremely demanding in terms of computing power. This paper focuses on improving the speed of solving the Riemann problem with the MUSTA-FORCE algorithm by employing the CUDA parallel programming model. We also propose a new approach to 3D finite difference algorithms, which employ a GPU that uses surface memory. Numerical experiments show an unprecedented increase in the computing power compared to a CPU.
