摘要: 服务调度技术是计算网格任务管理系统中的核心问题。为适应网格服务部署的需要,提出了一种基于自适应“模糊-PID"反馈控制模型的Agent技术,该技术融合了模糊理论与PID(Proportionment Integral-Differential coefficient)技术的优点。实验证明本技术能解决网格服务部署中的动态性和不确定性,并充分发挥网格服务的虚拟执行功能,可在网络带宽效率、延时和可靠性等方面做出更好的权衡。

Abstract: Grid service scheduling algorithms are kernel technictue in task management system of computing grid. Using a grid service deployment agent technology based on the fuzzy-PID feedback control model, a new grid service deployment agent technology was put forward for solving the uncertainty in task scheduling of the computing grid. This method fuses the fuzzy theories and PID technology. Theory analysis and numerical experiment illustrate that this method can express the dynamics and uncertainty of expected time to compute of tasks and bring the dummy executing competence into play in the computing grid environment, they are the generalization of traditional grid scheduling algorithms.At the same time, it can afford the balanced bandwidth, delay and reliability.
