| 摘 要： | 在研究现有分布式调度模式的基础上,提出了基于资源可用门限的分布式调度模式。该模式综合资源性能和负载情况,准确反映站点的当前使用状态,根据资源可用门限为作业请求选择局部站点。评估结果表明,与现有分布式模式相比,该模式降低了平均作业等待时间和平均作业响应时间,具有更好的调度性能,因此是一种高效的分布式调度模式。

| Abstract: | Based on the discussion of the existing distributed job scheduling schemes, a distributed job scheduling based on the resource availability threshold is proposed in this paper. In our scheme the resource status is investigated accurately according to the performance of and workloads on the resource; and the resources are selected for the requests of jobs according to the predetermined resource availability threshold. The simulation results show that the proposed scheme can reduce the average job wait time and the average job response time, and has better performance than the existing distributed schemes. |
