Abstract: Focusing on the complexity problem of managing and scheduling system resources in gird environment, this paper proposes a grid resources allocation model based on competition mechanism, which includes user layer, broker layer and resource layer. The resource allocation policy and a new cost optimization algorithm are proposed. Simulation experiments show that it fits the dynamic changes better in the grid environment and adjusts balance between supply and demand.

Key words: grid, task scheduling, competition

摘要： 针对在网格环境下对资源进行有效管理和调度的复杂性问题，提出一个基于竞争机制的网格资源分配模型，其中包括用户层、代理层及资源层。在该模型的基础上给出资源分配策略及一种费用优化算法。模拟实验表明，该模型能够较好地适应网格环境的动态变化，调整供给和需求的平衡。
