Abstract:
This paper presents virtual process schedule algorithm for cloud comping, and gives five constraints of uniform distribution, load threshold, increased level, quality control and generally mandatory. It uses the proposed algorithm to schedule safe virtual process, serious problems such as failing to allocating resources, system oscillation for migrating resources and active resource pool variation can be avoided because of the blind schedule instruction. Experimental result indicates that the algorithm considers related parameter and expected diversification to resolve adaptive schedule problem, it has excellent robustness.

摘要: 提出一种适用于云计算系统的虚拟进程自适应调度算法,给出均匀分配、负载门限、级别自增、质量控制和强制迁入5个约束,从而避免系统出现盲目调度引发的资源无效分配、迁移性震荡、活动资源池伸缩性震荡等情况。实验结果证明,该算法通过综合权衡各项指标与预期变化,能有效解决虚拟进程的自适应调度问题,具有较好的鲁棒性。
