摘要
En 中文
The two-dimensional barotropic vorticity equation is one of the basic equations of ocean dynamics. It is important to have efficient numerical solution techniques to solve this equation. In this paper, we present an implementation of a numerical solution using a Graphics Processing Unit (GPU). The speedup of the calculation on the GPU with respect to that on a CPU depends on the grid size, but reaches a factor of about 50 for resolutions from 2049 x 2049 up to 4097 x 4097. It may therefore be efficient to use green GPUs in future high-resolution ocean modelling studies. (C) 2011 Elsevier Ltd. All rights reserved.
