Conference Policies
Only PDF files will be accepted, uploaded to the submission link above. Each paper will receive a minimum of three reviews. Papers will be selected based on their originality, relevance, significance, technical clarity and soundness, presentation, language, and references. Submission implies the willingness of at least one of the authors to register and present the paper, if accepted. At least one of the authors of each accepted paper will have to register and attend (virtually) the HPCS 2020 conference to present the paper at the Symposium as scheduled. By submitting the paper to the HPCS conference, all authors agree to abide by all HPCS conference paper submission, publication and presentation policies as well as following ethical and professional codes of conduct, including those of the professional co-sponsoring organizations. For more information, please refer to the Authors Info and Registration Info pages.
Proceedings
Accepted papers will be published in the Conference proceedings. Instructions for final manuscript format and requirements will be posted on the HPCS 2020 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 or ACM Digital Library and indexed in all major indexing services accordingly.
SPECIAL ISSUE
Plans are underway to have the best papers, in extended version, selected for possible publication in a reputable journal as special issue. Detailed information will soon be announced and will be made available on the conference website.
If you have any questions about paper submission or the Workshop, please contact the Workshop's organizers.

SCOPE AND OBJECTIVES
Energy efficiency optimization has gradually become one fundamental constraint and requisite in the design of High Performance Computing (HPC) and Distributed Systems, comprehending several prominent research domains embracing the processor architectures (homogeneous/heterogeneous many-core GPPs), the processing accelerators and co-processors (e.g., APUs, GPUs, FPGAs, etc.), the distributed infrastructures (clusters, grids, data centers, etc.), the distributed platforms (application models, framework runtimes and virtual machines), and the underlying network and communication subsystem. Moreover, even in the embedded domain, saving energy in battery-supplied devices is established as a fundamental issue in mobile, hand-held and wireless applications and in most pervasive systems.
Accordingly, due to the often imposed thermal, power and energy constraints, an effective minimization and optimization of the energy consumption surpasses the obvious economic impact of the energy cost, since it also directly affects other aspects of the overall infrastructure with a significant influence on its viability, including the power supply and its distribution, cooling mechanisms (cost and space overhead) and management techniques, etc.
These new challenges require innovative and effective solutions to attain an effective optimization and/or minimization of the power consumption in HPC and distributed systems, including energy-efficient architectures, scheduling and mapping algorithms, load-balancing and scalability studies, and communication protocols.
The goal of this workshop is to bring together active researchers who are interested in prevailing issues and prominent challenges related to optimizing computing systems power consumption, energy efficient systems, power-aware distributed systems, and green computing.
Both theoretical papers and papers describing systems implementations and real-world practical experiences will be welcome.
The OPTIM Workshop topics of interest include (but are not limited to) the following:
Computer architecture trends for energy efficiency: Heterogeneous parallel processing architectures (e.g., ARM big.LITTLE); ISA diversity and morphable structures; run-time reconfiguration/adaptation and dynamic scalability; CPU accelerator co-design (GPUs, APUs, FPGAs, etc.); approximate computing techniques and architectures.
Energy/power management and control: Run-time power/energy monitoring and sensing; heat/power/energy models; Dynamic Voltage and Frequency Scaling (DVFS) and power/clock gating strategies; performance vs. power/energy scaling and management, Pervasive energy sharing.
Energy-aware large scale distributed systems: energy-efficient grids, clouds and data centers; exascale computing systems; energy-aware virtualization techniques for energy efficiency; energy-aware frameworks; virtual machines and network infrastructure management.
Energy-aware communication: energy-efficient models, protocols and routing algorithms applied in the physical (PHY), data-link (MAC), network (IP), transport (TCP/UDP) and middleware layers above; energy-efficient cross-layer protocols; energy trade offs between communication and computation; energy-efficient network services and operations.
Tools and algorithms: Programing languages, compilers and models for energy-aware computing; profiling and simulation tools for heat/power/energy estimation; power- and thermal-aware scheduling, mapping and task/thread migration policies for energy efficiency; energy-aware resource management; operating system support and energy management tools.
Green Computing: models, methodologies and paradigms; sustainable computing; management and balance between performance, reliability and energy consumption; standardization and benchmarking for energy-aware systems; integration with smart grids.
Wirelessly Powered Systems and Networks (WPSN): tools and techniques to design or improve relevant distributed operations using Wireless Power Transfer (WPT), as well as battery-less sensors, passive RFID, IoT, 5G and M2M solutions. WPT-enabled networking protocols, algorithms and optimization; WPT-enabled communication methods, tools and techniques; Far-/near-field WPT technologies for networks and communications.
