     Title: Between gaps and bursts: supporting GREEN-* approaches to reduce energy consumption in large scale distributed systems
     Abstract: With the emergence of large scale distributed systems (Data Centers, Grids, Clouds...), 
               the amount of energy (watts) required for high performance distributed computing and 
               networking becomes a real challenge. Taking into account of an efficient energy usage 
               will have an impact on how we design architectures, services and protocols. Various 
               GREEN-* approaches ("Green Computing", "Green networking", "Green programming"...) are 
               currently proposed by academics and industrial consortiums. This talk will review current 
               challenges and solutions associated to energy efficiency approaches in distributed systems. 

     Due to the interrupted airline service between Europe and US, Lefevre couldn't come. We were grateful that Wu Feng agreed to 
     give the keynote speak on "Green Computing Comes As Age"

      Energy Efficient Computing - Beyond Single Layer Optimization
      Coordinator: Karsten Schwan
      Panelists: Hsien-Hsin Lee, Georgia Tech; Konrad  Malkowski, Penn State; Hyesoon Kim, Georgia Tech

      Substantial opportunities for energy savings can be derived from cross-layer interactions 
      whereby the energy saving steps taken at one layer of abstraction are informed by information 
      provided by other layers. A typical example are system-level actions like DVFS informed by 
      application-level information about current performance requirements. Such opportunities, however, 
      exist across other abstraction levels, as well, such as controlling the generation of thermal 
      energy on chips via "thermal smearing" performed at system level. The topic of this panel is 
      to discuss and investigate for future systems opportunities for energy savings derived from 
      cross-stack information or interactions. Of particular interest are the heterogeneous platforms 
      comprised of general purpose cores and accelerators now increasingly common in both embedded 
      and high performance systems.
