Abstract
The accurate simulation of large scale hydrology cycles is a hot topic in the field of hydrology and parallel computing. Due to the huge computation amount, the process of the hydrology cycle should be parallelized and the high-performance computing is required. In this study, a parallel scheme of hydrology cycle is proposed by the parallelization of SWAT-the most popular hydrology simulation software. The potential parallelizable sections have been analyzed and exploited. Then a parallel framework based on MPI and OpenMP is proposed according to the structure of SWAT. Finally, the performance of this parallelism has been tested in the Shule River and the rivers in the northern slope of Tianshan Mountains. And the results show that this parallelism is suitable for the large scale hydrology simulations.
