摘　　要：为了更好地满足用户按需计算的要求,控制用户通过Portal使用网格资源的开销,定义了操作成本、成本效用等评价Portal性能的指标.逻辑设计上将服务与资源表示分离成网格高级服务层与Portal层,给出了用户与Portal交互的形式化描述.采用异步请求响应技术加快响应时间.测试结果表明:系统具有良好的可扩展性,能够有效地降低用户使用Portal的开销.To better satisfy user′s requirement of on-demand computing,and control the cost of using grid resources through Portal,metric such as operating cost,operating utility,were defined to evaluate the Portal performance.We separated the services and resource representation into two layers of grid advanced service and oortal,and proposed the formalized description of interaction between users and portal.Furthermore,a grid software sharing system portal was designed,which adopted asynchronous request/response technology to reduce response time.The test results indicate that the system has well scalability,can effectively reduce the cost of using portal.
