Previous offerings of WEED: 2009




The 2nd Workshop on Energy Efficient Design was conducted successfully at Saint-Malo, France on the 20th of June, 2010. The workshop provides a forum for the exchange of ideas on research on critical areas relating to energy-efficient computing, including energy-aware design techniques for systems (large and small), energy management policies and mechanisms, and standards for evaluating energy efficiency. It was well attended with a good mix of researchers and practitioners from industry and academia.

Without further ado, below is the final program of WEED 2010. Clicking on the titles below would take you to the presentations where available.
