With the continuous development of hardware and software, Graphics Processor Units (GPUs) have been used in the general-purpose computation field. They have emerged as a computational accelerator that dramatically reduces the application execution time with CPUs. To achieve high computing performance, a GPU typically includes hundreds of computing units.(More)
—GRAPES (Global and Regional Assimilation and Prediction System) is a new generation of numerical weather prediction (NWP) system of China. As the system processes amount of data and requires high real-time,so it is always a hot research field of parallel computing.This is the first time that we use GPU (Graphics Processor Unit) general-purpose computing(More)
