【摘要】 主动服务请求代理中间件提供资源代理主动监测网格节点上的资源,预测其未来处理能力并据此进行任务分配。该文对预测算法进行了改进和优化,提出了多变量资源性能预测算法,即利用NWS单变量预测值和实施收集的分布函数相结合来作出预测,从而进一步优化了网格性能。更多还原

【Abstract】 Proactive service broking middleware(PSRB)provides a few resource agents to proactively monitor the resources on grid nodes and forecast their future availability.Predictions are accepted as the primary fact for PSRB to select the best grid node for job assignment.This article proposes a new prediction algorithm,which is multi-variant resource performance forecasting technique,to make the grid perform more efficient.更多还原
