软件产品通常需要满足一些静态或动态的特性。众所周知的动态属性的例子是程序执行时间和软件性能优化的相关目标。随着生态环境问题的日益重要,软件产品的能耗也是一个越来越重要的动态特性。现代计算机系统已经提供了诸如多核和电压频率缩放等特性,以支持降低软件的能耗。然而,较低的程序执行时间和良好的能源效率可能是相互冲突的目标,并且很难同时减少程序执行时间和能源消耗。本文研究了软件的能量消耗与执行时间之间的关系,提出了一种基于任务型程序的软件调优方法,对不同的程序版本和不同的任务结构的执行时间和能耗进行评价,以选择最优解。
Software products are usually required to meet some static or dynamic properties. Well-known examples of dynamic properties are the program execution time and the related goal of software performance optimization. Because of the increasing importance of ecological and environmental issues, also the energy consumption of software products is a dynamic property of increasing importance. Modern computer systems already provide features, such as multicores and voltage-frequency scaling, to support the reduction of the energy consumption of software. However, a low program execution time and a good energy efficiency might be conflicting goals and it may be difficult so simultaneously reduce the program execution time and the energy consumption. In this article, the relation between energy effort and execution time of software is investigated and a software tuning method for task-based programs is proposed, which appraises different program versions and different task structures concerning their execution time and energy consumption with the objective to pick the most favorable solution.
