摘　　要：根据高性能计算和网格的特点,提出一种网格二次开发模型(GRM)。结合RMI和SSL/TLS技术,该模型提供了访问中间件的一致性接口,屏蔽了通过网络访问网格的繁杂问题,解决了敏感数据在不安全的广域网中传输的问题。以科学计算网格的中间件为基础,实现了GRM。多个基于GRM的用户接口开发经历和实验结果表明,GRM为开发人员提供了一个简单易用和功能全面的开发模型,而且具有良好的性能和可移植性。According to the characteristics of high-performance computation and computational grid, a Grid Redevelopment Model （ GRM） was proposed. Regarding the combination of Remote Method Invocation （ RMI） , and SSL /TLS technology, GRM firstly provided a consistent interface to access to grid middleware; secondly, screened the complex and trivial problems for accessing grid through network; thirdly, solved the data security issues for sensitive data transferred in insecure wide-area network. Based on the grid middleware used by scientific computing grid, the GRM was implemented. The case studies and experimental results of developing user interfaces based on GRM and experimental results show that, the GRM not only provides an easy, useful and full featured development model, but also has good performance and portable features.
