【摘要】 针对网格资源动态性、异构性的特点,提出基于双向拍卖进行网格资源管理的方法,构建基于双向拍卖的网格资源分配模型,描述模型中资源用户、用户代理、网格资源提供者及本地拍卖市场等组件的功能。根据买、卖双方的资源需求,提出双向拍卖算法及资源调度方案,利用资源价格的博弈机制,使交易双方能在不完全的信息环境下,获得各自最大的资源效用。进而,通过贝叶斯均衡计算,推算出双向拍卖中资源用户的最优化竞价策略,为有效地调节动态负载平衡、提高系统资源的使用率提供有益的参考。更多还原

【Abstract】 The authors propose a double auction-based method for grid resource management,and design a double auction-based grid scheduling model and describe the resource users,user agents,grid resource suppliers and local auction market of the model in view of the dynamic and heterogeneous nature of grid resources.Then the anthors put forward the double auction algorithm and resource scheduling strategy,which make the two transaction sides both gain the maximal resource use in the condition of incomplete information by consulting the game mechanism.Then with the help of Bayesian study,an optimization bidding strategy for double auction is derivated,which supplies useful references to adjusting dynamic load balancing efficiently and improving usage rate of system resources.更多还原
