Abstract: As scientific applications target extreme scales, energy-related challenges are becoming dominating concerns. As a result, it is critical to explore emerging architectures (e.g., with multiple cores and deep memory hierarchies) and applications (e.g., coupled simulation workflows) from an energy perspective and investigate associated overheads and tradeoffs. For example, energy/power-efficiency have to be addressed in combination with quality of solution, performance and reliability, and other objectives, and achieving the desired levels of reduction in power consumptions requires a comprehensive cross-layer and application-aware strategy. In this talk I will explore these issues and will describe recent related research efforts at the Rutgers Discovery Informatics Institute (RDI2).
Bio: Manish Parashar is Professor of Electrical and Computer Engineering at Rutgers University. He is the founding Director of the Rutgers Discovery Informatics Institute (RDI2) and of the NSF Cloud and Autonomic Computing Center (CAC), and is Associate Director of the Rutgers Center for Information Assurance (RUCIA). Manish received a BE degree from Bombay University, India and MS and Ph.D. degrees from Syracuse University.

Workshop description :
Improving the energy efficiency of large-scale distributed systems (e.g. data centres and Clouds) is a key challenge for both academic and industrial organizations. Although the topic has gained lots of attention over the past years, some of the proposed solutions often seem conservative and not easily applicable to large-scale systems. Their impact at large-scale remains to be proved. Hence, this workshop aims to provide a venue for discussion of ideas that can demonstrate "more than small % solution" to energy efficiency and their applicability to "real world". .
The ExtremeGreen workshop will focus on scientific and industrial approaches and solutions that could have a large impact in terms of energy savings and energy efficiency. Clean-slate approaches and innovative solutions breaking conventional approaches are welcome. The workshop also welcomes submissions of work-in-progress papers on ideas that can have a large impact on improving the energy efficiency of large-scale distributed systems. The papers must provide preliminary results that demonstrate the originality and possible impact of the proposed solutions.
Submissions will be reviewed by an international group of experts in distributed systems and energy efficiency.

Energy efficiency of data centers
Green networks for large scale distributed systems
