Unified GPU Parallel Framework Based on Discontinuous Galerkin Method
In this paper, we designed a unified parallel DG framework. Based on the characteristics of DG discretization, we built a preprocessing part in the framework. Then designed different kernel functions to match different numerical problems, such as Maxwell's equation and Euler's equation. A speed-up of 160 has been achieved over an equivalent CPU code. Compared with CPU code, the computing efficiency has been greatly improved.
