“…Software‐based approaches can be roughly categorized in 2 sets: source code instrumentation and energy profilers . Source code instrumentation consists in injecting profiling code into the applications code (or byte code), to capture all the necessary events related to EC.…”

SUMMARYIn the quest for energy efficient ICT, research has mostly focused on the role of hardware. However, the impact of software on energy consumption has been acknowledged as significant by researchers in software engineering. In spite of that, due to cost and time constraints, many software producing organizations are unable to effectively measure software energy consumption preventing them to include energy efficiency in the product roadmap. In this paper, we apply a software energy profiling method to reliably compare the energy consumed by a commercial software product across two consecutive releases. We demonstrate how the method can be applied and provide an in-depth analysis of energy consumption of software components. Additionally, we investigate the added value of these measurement for multiple stakeholders in a software producing organization, by means of semi-structured interviews. Our results show how the introduction of an encryption module caused a noticeable increase in the energy consumption of the product. Such results were deemed valuable by the stakeholders and provided insights on how specific software changes might affect energy consumption. In addition, our interviews show that such a quantification of software energy consumption helps to create awareness and eventually consider energy efficiency aspects when planning software releases.

“…A more simple software-only approach is to use energy profilers [26]; software tools including a power model with the ability to estimate the software EC on different levels of granularity. Unfortunately recent study has found energy profilers to not always provide the desired results [14].…”

“…Pro (WUP) capable of measuring the total power drawn by an entire system with a one second interval, measured the power drawn by the test server and performance data was collected using Perfmon, a standard performance monitoring tool with Microsoft Windows. A different deployment could require a more software intensive approach using, e.g., energy profilers [14]. Finally, the client system was used to trigger the required activity and data was collected remotely (i.e.…”

“…Quality properties, measures and measure elements provide a means to quantitatively describe software aspects related to EC. Through an experiment, that builds on a recently published case study [15], the perspective is validated. The potential of our research is demonstrated by realizing a reduction in energy consumption of 67.1 % in a case study.…”

Extending software architecture views with an energy consumption perspective

The rising energy consumption of the ICT industry has triggered a quest for more sustainable, i.e. energy efficient, ICT solutions. Software plays an essential role in finding these solutions, as software is identified as the true consumer of power. However, in this context, software is often treated as a single, complex entity instead of the interrelated elements that it actually consists of. Although useful results can be gained, this approach fails to provide detailed insight in the elements that invoke specific energy consumption behavior. As a result, software vendors are not able to address energy consumption on software level. In this paper, we propose an energy consumption perspective on software architecture as a means to provide this insight and enable analysis on the architectural elements that are the actual drivers behind the energy consumption. In support of this perspective, we also position sustainability as a potential quality attribute thereby provide a means to quantify energy consumption aspects related to software. In a case study using a commercial software product the perspective and quality attribute are applied, demonstrating the potential by achieving an energy consumption saving of 67.1 %.
