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.

  • Power-aware linear algebra libraries for energy-efficient HPC
  • Linear system solvers optimised for energy consumption on the respective hardware platform
  • Energy-optimised aerosol chemistry packages

Optimisations of existing ART and/or HAM version for CPUs, and integration into COSMO – Exa2Green researcher reports further progress in Work Package 5

Within Task 5.1.2 of Exa2Green Work Package 5 - Showcase for energy-optimised aerosol chemistry packages – researcher Joseph Charles of CSCS is reporting relevant progress:


Extended standalone model test framework
