List of Participants


The program of the Dagstuhl seminar 07041 on Power-aware Computing Systems featured presentations of about 25 participating researchers from academia and industry. They were chosen to represent major areas in targeting the energy consumption of a computing system—Applications, Compilers, Virtual-execution Environments, Operating Systems, and Hardware.

In order to continue the work of the predecessor Dagstuhl seminar held in 2005, the results of that seminar [1] were discussed, with the aim of developing a vision of challenges, problems, and research activities in some of the key areas identified in 2005. The first part of the seminar was dedicated to lively discussions that led to the identification of three areas that were considered being most interesting. As a result, three groups were formed to further identify challenges and opportunities. The results of these groups are presented in this report. In addition, abstracts of the presentations as well as work-in-progress papers are published in these proceedings.

The remainder of this section summarizes the starting point of the discussion by giving an overview of the results of the seminar in 2005. It is followed by a presentation of the results of the working groups on low-power design and reliability (Section 2), (Section 3), and power estimation and simulation (Section 4). Finally, Section 5 concludes this report. More information on the seminar described in this report and its predecessor in 2005 can be found in [2,3].

The second Dagstuhl seminar on Power-aware Computing Systems picked up the discussion results of its predecessor [1], and continued the discussion of challenges in the area. We think that the results, partly described in this report, partly described in the papers published as part of the seminar proceedings, are suited to give the involved communities ideas for future challenges. We would like to thank all participants of the seminar for making it a fruitful and inspiring event—and especially Dagstuhl’s wonderful staff, for their support both before and during the seminar.

Dagstuhl's Impact

Please inform us when a publication was published as a result from your seminar. These publications are listed in the category Dagstuhl's Impact and are presented on a special shelf on the ground floor of the library.


Furthermore, a comprehensive peer-reviewed collection of research papers can be published in the series Dagstuhl Follow-Ups.
