云環(huán)境下面向跨域作業(yè)的調(diào)度方法
[Abstract]:In the cloud environment, because of the data localization or the special preference of the task to the resource, the task contained by a job often needs to run on different data center points, such kind of job is called cross-domain job. The completion time of a cross-domain job depends on the execution efficiency of the slowest task, I. e., the bucket effect. In view of the unreasonable scheduling strategy under the condition of heterogeneous resource capacity of each domain, the problem that the time span of job execution across domains is too long, In this paper, a heuristic scheduling method for cross-domain jobs is proposed. MIN-Max-Min, prioritizes job execution with the shortest expected completion time. The experimental results show that compared with the first-come first-served strategy, this method can reduce the average execution time span of cross-domain jobs by more than 40%.
