Abstract: Unstructured grid has been widely used to establish hydrodynamic models.To rapidly get the calculation results without a cluster when the number of computational grids is too large,a high-performance computing technology which is based on GPU (graphic processing unit),is adopted to design a parallel algorithm and establish a 2D unstructured grid hydrodynamic model on CUDA (compute unified device architecture ) development platform. Through the comparisons to the computational efficiency of a cluster and the Graphic Card of GTX460,the advantages of GPU method are confirmed:the speedup ratio can reach more than 10 times and maintain a high growth as the increase of the number of computational grids.It is suitable for the numerical simulation of large-domain hydrodynamic models.
