Abstract: The paper proposes a grid trust model that deduces and synthesizes the values of trust with the subjective logic theory. It designs a kind of scheduling algorithm of task security level matching resource security level for resolving the problems of grid task scheduling algorithm at present. The algorithm screens resources with the security requirements, and makes it meet the earliest finish time. Simulation results indicate that the algorithm increases the task success ratio and reduces the job finish time. Therefore it is an efficient scheduling algorithm for scheduling in grid environment.

摘要: 提出了一个网格信任模型,用主观逻辑理论进行信任值的推导、综合。针对现有网格任务调度算法存在的问题,设计了一种任务和资源安全等级匹配的调度算法。通过安全需求对资源进行筛选,并使它满足最早完成时间。仿真实验表明,与传统经典网格任务调度算法比较,该算法提高了任务成功率,减少了任务完成时间,是网格环境下一种有效的资源调度模型。
