Key Exploitable Results (KERs)

Within ESiWACE3, Key Exploitable Results (KERs) include a portfolio of software tools, model codes, and applications developed to advance performance assessment and optimisation for Earth system modelling. These results support researchers and practitioners in analysing computational efficiency, testing scalability, and improving portability across emerging HPC architectures.

This section highlights these KERs and the results they generate, showcasing practical solutions built around realistic climate and weather workloads. By focusing on representative scientific use cases rather than synthetic metrics such as High Performance Linpack (HPL), they provide actionable insight into how computing systems perform for real modelling and forecasting applications.

  • R1 - HPCW

    WP1

    HPC Weather benchmarking suite. HPCW isolates key elements in the workflow of weather and climate prediction systems to improve performance and to allow a detailed performance comparison for different hardware platforms thus fostering co-design with vendors and technology providers

  • R25- Docker EC-EARTH

    WP1

    Containerization of the code EC-EARTH for running climate simulation (comes from AUTOSUBMIT WF manager and EC-EARTH)

  • R24-Containerization of EC-Earth

    WP1

    Containerisation is one potential approach to port EC-Earth to new systems, which includes pre-exascale systems. Given that access to tier 0 systems usually comes with severe time constraints and strong focus on actual production runs, container based porting can help to better utilise the assigned resources.

  • R14-FVM

    WP2

    This is the new dynamical core of ECMWF that will be used for operational weather predictions and climate simulations. The model has been developed outside of ESiWACE but ESiWACE is supporting the porting of the dycore to GPU hardware and heteoregeneous hardware via the GT4Py DSL

  • R11-FDO4Climate: Initial Evaluation

    WP3

    Evaluation of the readiness of published climate simulation output for automated anaysis. High potential because automated analysability of climate data has not been evaluate before and because specifications to enhance/enable machine actionability can be deduced from this work
