摘　　要：云数据管理系统是一种新兴的数据管理系统.为了研究云数据管理系统的能耗优化,实现"绿色计算",首先要定义能耗的度量模型和基准测试方法,分析系统的能耗特点.目前云数据管理系统的基准测试主要集中在性能方面,对能耗方面的评估和优化工作很少;对测量仪器、测试手段、测试用例以及能耗基本规律的研究存在空白.文中提出了一种能耗的度量模型和数学表达;定义了一组数据装载、查询和分析用例来测试云数据管理系统的能耗;设计了系统能耗的测量方法;分析了若干云数据管理系统在执行数据装载、读取、查询、聚集和连接等操作时的能耗特征,提出了通过降低"等待能耗"而进行云数据管理系统的能耗优化.大量实验数据证明,尽管云计算被认为是一种绿色计算,但文中测试的云数据管理系统在能耗方面差异较大,需要对部分系统进行进一步的优化.Cloud Data Management System （CDMS） is a new rising data management system. To achieve the ＂green computing＂ and study the Energy Consumption （EC） of CDMS, firstly, the measurement and benchmarking approaches of EC should be defined, and the EC characteris- tics of CDMS should be studied. Currently, the benchmarking of CDMS is mainly focuses on per- formance issue, and few of them are about evaluation and optimization of EC, or introduce the measuring instrument, measuring approach, test cases and basic features of EC. In this paper, the measurement of EC and its mathematical expression are proposed; the benchmarking cases including data loading, querying and analyzing are defined; the evaluation approaches of EC of CDMS are designed; the EC of executing loading, retrieving, querying, aggregation and join in several CDMSs are analyzed; the approach of ＂reducing awaiting EC＂ is also proposed for optimi- zing the EC of CDMS. Plenties of experiment results show that, despite that CDMS is an applica- tion of ＂green computing＂ , the EC of the selected CDMSs are in great difference, and some of them should be well optimized.
