摘要 各种研究表明云计算中心的能耗问题已经成为研究云计算的一个新领域。云计算中心在运行过程中存在空闲的服务器节点,这些服务器节点会产生不必要的空闲能耗,以及由于任务调度不科学而产生大量能量浪费问题。针对这些问题,提出一种基于云计算环境下的降低能耗RECMSA算法。首先,建立云计算环境的能耗模型。然后,利用云计算中心的平均资源利用率将服务器节点分为两类,使用RECMSA(ReduceEnergy-Consumption-MigrationScheduling-Algorithm)算法对两类服务器节点进行匹配和调度,目的是通过迁移和调度后既要让云计算中心的资源利用率提高,又要让云计算中心的整体耗能降低。实验结果表明,该算法在能够完成任务的情况下,达到提高资源利用率和降低整体能耗的目的。
