一种临时私有云中逻辑拓扑感知的作业调度算法
A Logic-topology-aware Job Scheduling Algorithm in Temporary Private Cloud
摘要
Abstract
Considering the cost and flexibility,building a temporary private cloud in public cloud to replace the local physical cluster is an effective way for users to run a large number of parallel jobs during a particular period. However,the existing scheduling algorithms are not suitable for temporary private cloud hosting tightly coupled parallel applications, because they can not use the logic topology information of temporary private cloud, which probably results in the performance degradation of such type of applications. To mitigate such impact, a logic-topology-aware scheduling algorithm is presented. It builds the logic topology of virtual machines according to bandwidth and latency among them, makes scheduling decisions based on the logic topology and the information of applications. Experimental results show that compared with Round Robin and Random algorithms of open-source cloud software,logic-topology-aware scheduling algorithm improves the performance of tightly coupled parallel applications.关键词
