本文以一个数据中心为背景,研究了由两个并行队列组成的系统中的联合调度和服务器睡眠状态控制问题。使用马尔可夫决策过程理论和一种新的前瞻性方法,我们明确地确定接近最优的控制策略,最大限度地减少由于切换的QoE成本,能源成本和磨损成本的组合。指导方针提供了当这些综合政策是最有效的。
Motivated by a data center setting, we study the problem of joint dispatching and server sleep state control in a system consisting of two queues in parallel. Using the theory of Markov decision processes and a novel lookahead approach, we explicitly determine near-optimal control policies that minimize a combination of QoE costs, energy costs, and wear and tear costs due to switching. Guidelines are provided as to when these combined policies are most effective.
