The European climate community is represented by the European Network for Earth System Modelling (ENES). Since numerical weather prediction and climate modelling require more computing power, it is a driver for further HPC developments. Therefore, it takes part in the European HPC Strategy and participates in all three of its funding pillars.

HPC facilities
Access to HPC facilities is provided by the Partnership for Advanced Computing in Europe (PRACE). For advice on all relevant issues of HPC for the European climate modelling community, such as those related to the PRACE European facility and software developments, the HPC Task force of ENES was established.
The European High-Performance Computing Joint Undertaking (EuroHPC JU) aims at acquiring two pre-exascale machines by 2020 and finally, in 2023 two exascale systems, at least one of them with European technology.
HPC technologies (FETHPC)
Future emerging technologies for weather and climate modelling are being developed within the projects:
- European co-design for exascale applications (EuroExa), which targets providing the template for an upcoming exascale system
- Energy-efficient SCalable Algorithms for weather Prediction at Exascale (ESCAPE), which focuses on defining and encapsulating the fundamental algorithmic building blocks underlying weather and climate services. This is the prerequisite for any subsequent co-design, optimization, and adaptation efforts.
- The follow-on project ESCAPE-2 is providing the key components, e.g. a domain specific language for representative benchmarks to be deployed on extreme-scale demonstrators and beyond.
HPC applications (EINFRA)
Beside the ESiWACE and ESiWACE2 projects, adaption of leading weather and climate models on (pre-)exascale systems is provided by the following projects:
-
Infrastructure for the European Network of Earth System Modelling (IS-ENES) projects of the distributed e-infrastructure of models, model data and metadata of ENES. It gathers together the European modelling community working on understanding and predicting climate variability and change.
-
The Coupled Model Intercomparison Project phase 6 (CMIP6), an international endeavour to better understand past, present and future climate changes. It referes to the Grand Science Challenges of the World Climate Research Programme (WCRP).
-
Process-based climate simulation: Advances in high-resolution modelling and European climate risk assessment (PRIMAVERA), which develops a new generation of advanced and well-evaluated high-resolution global climate models capable of simulating and predicting regional climate with unprecedented fidelity, for the benefit of governments, business and society in general.
