【摘要】：当研究人员提出新的Web集群节能部署策略需要对其进行评测时,进行实际测试需要消耗大量的设备、时间及能源,为此提出一种基于Cloud Sim的节能部署仿真方案,其支持周期式的和条件式的部署触发方式。该方案能仿真请求的产生、调度和服务,以及服务节点的开关和CPU频率调整,并计算平均响应时间、能耗等性能指标。由于考虑了现实中服务节点的各种可能状态及状态转换,因而能耗计算较为准确。良好的数据结构设计使得该方案结构清晰、扩展性好。采用该方案对提出的基于概率调度的贪婪部署策略进行了仿真,仿真结果验证了仿真方案的可行性。
[Abstract]:When researchers have proposed that new Web cluster energy saving deployment strategy needs to be evaluated, a lot of equipment, time and energy need to be consumed in actual testing. An energy-saving deployment simulation scheme based on Cloud Sim is proposed, which supports the periodic and conditional deployment triggering mode. This scheme can simulate the production of requests and adjust the request. Degree and service, as well as switch and CPU frequency adjustment of service nodes, and calculate average response time, energy consumption and other performance indicators. Due to the consideration of various possible state and state conversion of service nodes in reality, the calculation of energy consumption is more accurate. Good data structure design makes the scheme clear and expansibility. The scheme is adopted. The simulation of the greedy deployment strategy based on probabilistic scheduling is carried out, and the simulation results verify the feasibility of the simulation scheme.
