- KonferenzbeitragGreening software with continuous energy efficiency measurement(INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Drangmeister, Jakob; Kern, Eva; Dick, Markus; Naumann, Stefan; Sparmann, Gisela; Guldner, AchimThe energy consumption of information and communication technology (ICT) is still increasing. Several solutions regarding the hardware side of Green IT exist, until now the software contribution to Green IT is not considered sufficiently apart from scientific research. In our paper, we discuss a new method of improving the energy efficiency of software during its development, by putting energy efficiency measurements into practice. Therefore, we measure and rate energy consumption and efficiency during the software development process, based upon software testing and Continuous Integration (CI).
- KonferenzbeitragIntegrating Aspects of Carbon Footprints and Continuous Energy Efficiency Measurements into Green and Sustainable Software Engineering(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Kern, Eva; Dick, Markus; Drangmeister, Jakob; Hiller, Tim; Naumann, Stefan; Guldner, AchimThe energy consumption of information and communication technology (ICT) is still increasing. Even though, up to now, several solutions regarding the hardware side of Green IT exist, the software contribution to Green IT is not well investigated. In our paper, we discuss how to integrate some aspects of carbon footprint calculation into software development processes and we show how ongoing energy efficiency measurements can be established as an integral part of a software development project.
- KonferenzbeitragMeasurement and Rating of Software-induced Energy Consumption of Desktop PCs and Servers(Innovations in Sharing Environmental Observations and Information, 2011) Dick, Markus; Kern, Eva; Drangmeister, Jakob; Naumann, Stefan; Johann, TimoUp to now, the power consumption of ICT is still increasing. However, it is not clear whether or not energy savings through ICT overcompensate this increasing energy consumption. There are manifold efforts of Green IT addressing energy efficiency of computer hardware, but there is a lack of models, descriptions, or realizations in the field of computer software. In our paper, we present a method to measure and rate software-induced energy consumption of stand-alone applications on desktop computers as well as interactive transaction-based applications on servers. In both cases, realistic workloads are applied. Our test rig contains the tested system, an appropriate power meter, a workload generator, and a data evaluation system. Our measurement method is intended to support software developers, purchasers, administrators, and users in making informed decisions on software architecture and implementation as well as on software products they use or plan to use. As a proof of concept, we will describe two exemplary measurements that show the influence of software use on power consumption.
