As part of the IEEE International Green and Sustainable Computing conference, a special workshop termed Energy-efficient Networks of Computers: from the Chip to the Cloud (E2NC) will be organized to address various design aspects of power efficient and dependable computing infrastructures. Computing machinery around the world consumes staggering amounts of energy. The increasing power consumption of Integrated Circuits has plagued the semiconductor industry for years. Soaring power dissipations have proved to be the limiting factor for increase in performance. Complex digital integrated circuits consisting of multiple components or cores form the underlying hardware for these massive computing infrastructures. Warehouse-scale computers powered by such multicore chips have applications in several important domains ranging from scientific applications like weather or economic forecasting, astronomical data analysis, bioinformatics applications to even consumer electronics. This has necessitated paradigm shifts in the IT and semiconductor industries at various levels. While major research is dedicated towards designing energy-efficient hardware, the aspect of reliability and dependability cannot be overlooked. This workshop will encompass a broad range of topics related to power efficiency and dependability of modern multicore chips as well as large scale computing infrastructures including the cloud. Its objective is to facilitate exchange of valuable information and ideas among researchers and practitioners. The workshop will consist of invited presentations and contributed peer-reviewed research papers.
