统一计算设备架构技术的应用研究进展

Advances in Application of Compute Unified Device Architecture Technology

统一计算设备架构(Compute Unified Device Architecture,CUDA)是NVIDIA公司近年来推出的针对图像处理单元(Graphics Processing Unit,GPU)的全新并行计算框架。借助其C语言兼容特性以及GPU的强大并行计算能力,CUDA技术在图像处理、科学计算等领域取得了良好的加速效果。文章在对CUDA技术的应用情况进行回顾和总结的基础上,重点介绍了不同应用中采用CUDA技术进行计算加速的原理,并探讨了CUDA技术今后的发展方向。

Compute Unified Device Architecture（CUDA） is the recently released brand new parallel computing frame- work for Graphics Processing Units（GPU） by NVIDIA. By virtue of its C-compatibility and the powerful parallel computing ability of GPU, CUDA has achieved superior acceleration performance in various areas such as image processing, high per- formance computing. Based on summarizing the application of CUDA, this paper especially introduces the acceleration principles with the aid of CUDA technology. MeanwhiIe, the development of CUDA is also discussed.
