Abstract: This paper presents a network-based general computing platform which provides computation as a service to enable the mobile terminals such as smart phones and tablet PCs to do complex computational work. Based on the expandability of ParaViewWeb’s framework, capabilities of high-performance general computing with GPUs are added while the original functions of 3-D data analysis and visualization are kept. Now the GPU computing resources of the server can be called remotely on this platform. The platform is tested with a medical image filtering application and the experimental result shows the significant acceleration of the web-based application compared to the locally running application.

摘要： 针对智能手机、平板电脑等移动终端计算能力有限的问题，提出一种基于网络的通用计算服务平台。该平台以服务的方式为移动终端提供远程计算支持，增强其进行复杂运算的能力。利用ParaViewWeb架构的可扩展性，将高性能GPU通用计算与ParaViewWeb架构结合，在保留ParaViewWeb原有的三维数据分析与可视化功能的基础上，扩展其远程调用服务器GPU运算资源的能力。选取医学图像滤波算法为实验对象，验证了该平台的有效性，结果表明对比本地应用，基于网络的应用取得了显著加速。
