SCOPE AND OBJECTIVES
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 OPTIM 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
Green HPC through Servers, Virtual Machines and Network Infrastructure Management
Power- and thermal-aware algorithms, software, and hardware

INSTRUCTIONS FOR PAPER SUBMISSIONS:
You are invited to submit original and unpublished research works on above and other topics related to optimization issues in energy efficient distributed systems.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. We welcome prospective participants to submit either full papers (up to 8 pages) or short papers ( up to 4 pages). Poster papers and posters (please refer to http://hpcs2015.cisedu.info/home/cts-2015-posters for the posters submission details) will also be accepted for submission. The manuscript should use the two-column IEEE format. Additional pages will be charged at additional fee. In case of multiple authors, an indication of which author is responsible for correspondence must be indicated. Please include page numbers on all submissions to make it easier for reviewers to provide helpful comments.

Submit a PDF copy of your full manuscript using the Workshop Easy Chair link at https://www.easychair.org/conferences/?conf=optim2015. Acknowledgement will be sent within 48 hours of submission.

Only PDF files will be accepted. Each paper will receive a minimum of three reviews. Papers will be selected based on their originality, relevance, contributions, 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.


PROCEEDINGS
Accepted papers will be published in the conference proceedings. Instructions for final manuscript format and requirements will be posted on the HPCS 2015 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 to be published as ISBN proceedings by the IEEE and will be available online through IEEE Digital Library and indexed by major indexing services accordingly (e.g., EI indexing).
