提出一种基于内存共享机制数据中心进程优化调度策略,并基于软件定义网络(SDN)架构建立数据中心负载模型及内存节点能耗模型,给出2个用于降低内存能耗的启发式进程调度算法.这2个算法以实际内存节点为研究对象,在保证数据中心负载均衡的基础上,通过合理进程调度实现内存共享率最大,使得处于活动态的内存节点数最少,从而达到数据中心内存能耗优化目的.仿真结果表明,提出的启发式进程调度算法能有效降低内存能耗.
A scheduling strategy based on memory sharing mechanism for data center process optimization is proposed. Based on software defined network (SDN) architecture, a data center load model and a memory node energy consumption model are established. Two heuristic processes are proposed to reduce memory consumption Algorithm.These two algorithms take the actual memory node as the research object, guarantee the data center load balancing, based on reasonable process scheduling to achieve the maximum memory sharing rate, making the number of active memory nodes at least, so as to achieve the data center memory The purpose of optimizing the consumption.The simulation results show that the proposed heuristic scheduling algorithm can effectively reduce the memory consumption.
