An optimized GPU implementation of a 2D free surface simulation model on unstructured meshes
A GPU implementation of a FV method for the 2D Shallow Water Equations is presented. Structured and unstructured meshes allow different implementations. NVIDIA C2070 GPU is compared against Intel Core 2 Quad Processor. The basic GPU implementation obtains between 20 and 30 of speed-up. Some strategies on the mesh order allow to double the performance, reaching 50.
