Workshop 02-OPTIM

International Workshop on Optimization Issues in Energy Efficient Distributed Systems

(OPTIM 2012)


As part of

The International Conference on High Performance Computing & Simulation (HPCS 2012) or

July 2 – July 6, 2012

Madrid, Spain

Submission Deadline: March 28, 2012


Minimization of energy consumption has become a central issue in designing distributed systems that range from wireless ad hoc networks to data centers.

Because battery technologies have not yet matched advances in hardware and software technologies, saving energy in battery-operated devices is very important for mobile/wireless networks. Similarly, minimizing energy consumption in high performance computing centers will, in addition to saving power consumption, require less cooling mechanisms.

These new challenges require innovative and effective optimization solutions for minimizing power consumption in distributed systems, such as energy-efficient scheduling algorithms and energy-efficient Medium Access Control (MAC) protocols.

The goal of this workshop is to bring together researchers who are interested in addressing issues of concern and challenges related to optimizing computing system power consumption, energy efficient systems, and distributed systems.

Both theoretical papers and papers describing practical experiences will be welcome.

The Workshop topics of interest include (but are not limited to) the following:

    • Optimization of Energy-efficient Protocols/Algorithms

    • Energy-efficient Scheduling Algorithms

    • Energy-efficient Cross-layer Protocols

    • Energy-efficient MAC Protocols

    • Energy-efficient Routing Protocols

    • Voltage and Frequency Scaled Networks

    • Energy-efficient Communication Protocols

    • Energy-efficient Protocols/Algorithms in PHY, IP Layers or Above

    • Hardware Solutions for Achieving Energy Efficiency in Large-scale Networked Systems

    • Virtualization Techniques for Energy Efficiency

    • Network Models and Simulation Modules/Tools for Energy Efficient Solutions


You are invited to submit original and unpublished research works on above and other topics related to optimization issues in energy efficient distributed systems. Submitted papers must not have been published or simultaneously submitted elsewhere. Submission should include a cover page with authors' names, affiliation addresses, fax numbers, phone numbers, and email addresses. Please, indicate clearly the corresponding author and include up to 6 keywords from the above list of topics and an abstract of no more than 400 words. The full manuscript should be at most 7 pages using the two-column IEEE format. Additional pages will be charged additional fee. Please include page numbers on all preliminary submissions to make it easier for reviewers to provide helpful comments.

Submit a PDF copy of your full manuscript via email to the Workshop organizers at and

Only PDF files will be accepted, sent by email to the workshop organizers. Each paper will receive a minimum of three reviews. Papers will be selected based on their originality, relevance, technical clarity and presentation. Submission implies the willingness of at least one of the authors to register and present the paper, if accepted. Authors of accepted papers must guarantee that their papers will be registered and presented at the workshop.

Accepted papers will be published in the Conference proceedings. Instructions for final manuscript format and requirements will be posted on the HPCS 2012 Conference web site. It is our intent to have the proceedings formally published in hard and soft copies and be available at the time of the conference. The proceedings is projected to be included in the IEEE Digital Library and indexed accordingly.

Extended versions of selected papers will be considered for publication in a special issue of the Future Generation Computer Systems Journal (FGCS - Elsevier - Impact Factor 2.365)

If you have any questions about paper submission or the workshop, please contact the workshop organizers.
