Power and energy consumptions become key constraints of many computer systems from smartphones to data centers. While power and energy consumptions have gained a lot of attentions over the years, the proposed solutions are mainly confined within systems software and algorithms for computation. This workshop aims to provide a venue for discussion of a broader spectrum of approaches to green computing including programming and execution paradigm, and of extensions from computing to data processing.

The topics of interest for this workshop include:
  • Power and energy characteristics of programs
  • Energy-efficient programming
  • Power-aware compiling
  • Power-aware scheduling
  • Energy-efficient resource management
  • Energy-efficient big data processing and analytics
  • Energy-efficiency of storage systems
  • Power-aware cloud computing
  • Energy-efficient heterogeneous computing
  • Energy-efficient scalable computing
Paper Submission and Publication:

Authors are invited to submit manuscripts reporting original unpublished research and recent developments in the topics related to the workshop. Submissions should include an abstract, key words, the e-mail address of the corresponding author. All submitted papers should follow the conference submission instructions .

All papers should be submitted electronically (in PDF format) using the workshop submission system. Submission of a paper should be regarded as an undertaking that, should the paper be accepted, at least one of the authors will register and attend the workshop to present the work. Each submitted paper will be peer reviewed and the comments will be provided to the authors. The accepted papers will be published in the workshop  proceedings by the IEEE Computer Society Press and IEEE online library.
