About Exa2Green

Exa2Green: Energy-Aware Sustainable Computing on Future Technology – Paving the Road to Exascale Computing


Exa2Green is a 3-year research project co-funded under the EU 7th Framework Program Future and Emerging Technologies (FET) Proactive Initiative: Minimising Energy Consumption of Computing to the Limit (MINECC). FET aims to go beyond the conventional boundaries of ICT and ventures into uncharted areas, often inspired by and in close collaboration with other scientific disciplines.

Exa2Green partners attend 1st Workshop On Approximate Computing (WAPCO 2015)

Research in the last few years has focused on approximate computing as a means to overcome the energy scaling barrier of computer systems. Energy savings can be achieved by utilizing the inherent error resilience of algorithms in many application domains such as signal processing,

EXA2GREEN is co-financed by the European Commission under the 7th Framework Programme
