International Workshop on Energy-aware high performance Heterogeneous Architectures and Accelerators

(WEHA 2016)


As part of

The International Conference on High Performance Computing & Simulation (HPCS 2016) or

July 18 – July 22, 2016

Submission Deadline: April 14, 2016 - Extended

Submissions could be for full papers, short papers, poster papers, or posters


The last decade has seen significant changes in processor architectures to improve computing performances and to overcome the physical limitations of increasing the clock frequency.

This allowed processors to still scale according to Moore's law. However, a new challenge is becoming relevant today: The ever increasing power and energy requirements for operating the latest generation of HPC systems are key factors in limiting the peek performances of newer HPC systems and might make Exascale computing unsustainable for both technical and economic reasons.

A possible solution is to find disruptive technologies in terms of new hardware architectures and energy aware system software which maximize the performance of HPC systems within a given power or energy budget.

For example, accelerators -- like GPUs, co-Processors, FPGAs -- and many-core low-power SoCs address this issue using different strategies.

The use of these is becoming more and more relevant in high performance computing. A challenge is a proper system design in order to be able to optimize the energy to solution and the time to solution for all applications running on the HPC system. Additionally, the interaction between the data center cooling infrastructure, the HPC system, the HPC system software -- including but not limited to scheduling systems, compilers, and run-time tools - and the running applications, have a great impact on the final power and energy efficiency of current and future HPC systems.

The workshop aims to strongly encourage the exchange of experiences and knowledge in novel solutions for improving the power and energy efficiency of HPC systems, and their application in HPC data centers. It focuses on analyzing and assessing new trends for high performance architecture, accelerators, and related changes in application algorithm design able to minimize the power and energy requirements for current and future HPC systems. Additionally, the workshop will look at challenges and tools for integrating the new generation HPC systems with the data centers for improved power and energy efficiency.

The authors of the papers selected for the workshop may be invited to submit extended versions of their manuscripts to be considered for publication in a special issue.

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

  • New Energy-aware Hardware Design

  • Algorithms and hardware architectures for reduced power, energy and heat

  • Power Prediction and Consumption Models and Monitoring Tools

  • Distributed infrastructures for collecting energy data and relevant context information

  • Accelerated Computing and Energy

  • Energy-aware Compiler and Run-time Tools

  • Data Centers and Resource Management Integration

  • Novel Accelerator Architectures

  • Energy-Efficient Programming models for computing paradigms (e.g., near-threshold computing, approximate computing, or neuromorphic computing)

  • Languages and Compilers for Hardware Accelerators

  • Libraries and Tools to Optimize the Programming of Hardware Accelerators

  • Manual and Automatic Energy Optimization Techniques

  • Benchmarking of Energy Aware Hardware Accelerators

  • Modeling and Performance Prediction for Hardware Accelerators

  • Energy management in operating systems and runtime systems

  • Energy management of the memory sub-systems, displays, and peripherals

  • Energy-efficient Application Development Experience

  • Application-specific Acceleration Hardware/Software

  • Tradeoffs between performance, reliability and energy efficiency

  • Energy-aware Applications using HPC Systems

  • Case Studies


You are invited to submit original and unpublished research works on above and other topics related to Energy-aware high performance heterogeneous architectures and accelerators. Submitted papers must not have been published or simultaneously submitted elsewhere. For Regular papers, please submit a PDF copy of your full manuscript, not to exceed 8 double-column formatted pages per template, and include up to 6 keywords and an abstract of no more than 400 words. Additional pages will be charged additional fee. Submission should include a cover page with authors' names, affiliation addresses, fax numbers, phone numbers, and all authors email addresses. Please, indicate clearly the corresponding author(s) although all authors are equally responsible for the manuscript. Short papers (up to 4 pages), poster papers and posters (please refer to for posters submission details) will also be considered. Please specify the type of submission you have. 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 to the workshop paper submission EasyChair site at Acknowledgement will be sent within 48 hours of submission.

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 presentation, 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 the HPCS 2016 conference to present the paper 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 2016 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 in all major indexing services accordingly.

A planned special issue of the Journal Concurrency and Computation: Practice and Experience will be available for selected papers of the conference. Best papers will be invited to submit an extended version.

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