摘要
本文概述了国产化计算平台的发展现状，对地理信息显示要求及国产化计算平台的不足进行分析，并在此基础上设计了4种国产化计算平台地理信息快速显示方案：即基于本机GPU加速、基于服务器端GPU加速、纯软件优化和数据优化组织方案。试验结果表明，基于GPU加速类方案可以很好地满足实用要求；数据优化组织技术方案可满足显示要求；纯软件优化方案不能满足要求。
The development status of domestic computing platform is summarized. Based on the analysis of the display re- quirements of geographic information and the deficiencies of domestic computing platform, four types of rapid geographic informa- tion display schemes are designed, including local GPU acceleration, GPU acceleration on server-end, pure software optimization and data optimization organization scheme. Test results show that the GPU acceleration scheme can satisfy practical requirements, the data optimization organization scheme can only meet the need of geographic information display and the pure software optimiza- tion scheme fails.
