摘要: 针对NetSolve系统与Web服务的结合技术,提出面向服务的计算网格中间件的系统结构,在该结构中对计算网格中间件系统的 3层功能结构进行体现,采用Java技术实现基于Web服务与原NetSolve系统的数值计算网格中间件WebSolve。 应用并行预条件共轭梯度算法在新系统上进行多次大规模方程组求解,测试结果证明该系统接口友好,对粗粒度并行的加速比可达O(n)。

关键词: Web服务, 计算网格中间件, WebSolve系统, 预条件共轭梯度法

Abstract: According to the integrated technology of NetSolve and Web services, this paper gives services-oriented computing grid middleware architecture, and embeds the 3-layers function architecture of computing grid middleware in it. WebSolve system based on Web services is implemented with Java. performance evaluation with parallel Precondition Conjugate Gradients(PCG) is made to solve equations set several times, whose stepped-up is O(n).

Key words: Web services, computing grid middleware, WebSolve system, Preconditioned Conjugate Gradients(PCG)
