GREEN is a version of ESPRESO developed under the Horizon 2020 project READEX (RUNTIME EXPLOITATION OF APPLICATION DYNAMISM FOR ENERGY-EFFICIENT EXASCALE COMPUTING). This project have started in September 2015 and therefore this version in early development stage. Ultimate goal for the ESPRESO team is to develop a power efficient version of the Total and Hybrid FETI solver that does not solve the problem in a shortest possible time but rather minimizes the power consumption.

This can be achieved by setting up the hardware parameters such as processor frequency, number of active cores or threads into optimal configuration. Main focus of the READEX project is to explore the dynamic behavioral of the application and find optimal runtime settings for different stages of the solver.

We will bring more information as the development moves forward.
