摘要
网格资源管理是网格计算首要解决的核心问题。现行的网格资源管理模型通常需要在网格系统中建立一个高于其他节点的自身庞大的管理体系,以掌握全网格内资源动态信息,实现全局资源调配,这种模式的主要问题是管理成本高且资源配置效率低。文章基于市场经济中的招投标机理,提出了一种新的网格资源管理模型,本模型的资源分配机制是根据网格内资源供需关系和资源的市场价格通过招投标方式来决定。网格内站点是否参与网格计算交易活动,完全由站点自主地根据自身资源现状和资源的市场价格来确定而不需要一个高于自己的管理机构,本模型是一个完全的市场经济的资源分配模型。
Grid resources management is the first priority problem in grid computing.Currently,many grid resources management models require establishing a bulky management system higher than other nodes in the grid system,so as to hold the dynamic information of all grid resources,and realize the allocation of global resources.The main disadvantages of these patterns are high management costs and low efficiency of resource configuration.In this paper,a new grid resources management model based on bidding mechanism in market economy is presented.Bidding and inviting public bidding according to supply and demand and market prices of grid resources determines the allocation mechanism of this model.Whether grid nodes participate in grid computing is totally decided by their resources conditions and market prices without a higher management agency.Thus,the model is a complete market economy resource allocation model.
