Projects

Current Projects:

  • EXCESS: The EXCESS project aims at providing radically new energy execution models forming foundations for energy-efficient computing paradigms that will enable two orders of magnitude improvements in energy efficiency for computing systems. A holistic approach that involves both hardware and software aspects together has the best chances to successfully address the energy efficiency problem and discover innovative solutions. EXCESS proposed models will try to describe and bridge embedded processors models with general purpose ones. The EXCESS project is going to be driven by the following technical components that are going to be developed during EXCESS:

    • Complete software stacks (including programming models, libraries/algorithms and runtimes) for energy efficient computing;
    • Uniform, generic development methodology and prototype software tools that enable leveraging additional optimisation opportunities for energy-efficient computing by coordinating optimisation knobs at the different levels of the system stack, enabled by appropriate modelling abstractions at each level;
    • Configurable energy-aware simulation systems for future energy-efficient architectures.


  • CoolEmAll: The main goal of CoolEmAll is to provide advanced simulation, visualisation and decision support tools along with blueprints of computing building blocks for modular data centre environments. Once developed, these tools and blueprints should help to minimise the energy consumption, and consequently the CO2 emissions of the whole IT infrastructure with related facilities. This will be achieved by:

    • Design of diverse types of computing building blocks (ComputeBox Blueprints) well defined by energy efficiency metrics;
    • Development of simulation, visualisation and decision support toolkit (SVD Toolkit) that will enable analysis and optimization of IT infrastructures built of these building blocks;
    • Both computing boxes and the toolkit should take into account three aspects that have major impact on actual energy consumption: cooling model, application properties, and workload and resource management policies.
