Abstract: ESiWACE will substantially improve efficiency and productivity of numerical weather and climate simulation on high-performance computing platforms by supporting the end-to-end workflow of global Earth system modelling in HPC environment. This will be obtained by improving and supporting:
- Scalability of models, tools and data management on state-of-the-art supercomputer systems
- Usability of models and tools throughout the European HPC eco-system, and
- Exploitability of the huge amount of resulting data.
We will develop solutions for cross-cutting HPC challenges particular to the weather and climate domain. This will range from the development of specific software products to the deployment of user facing services for both, computing and storage. Involving expertise on climate and weather modelling, model coupling, IO, performance analysis and workflow management, just to name a few, ESiWACE is truly interdisciplinary (for more information, see answer (3) of the nine CoE questions).
With regard to the upcoming exascale era, ESiWACE will establish demonstrator simulations, which will be run at highest affordable resolutions (target 1km) to estimate the computability of configurations that will be sufficient to address key scientific challenges in weather and climate prediction.

ESiWACE leverages two established European networks, namely:
- the European Network for Earth System modelling (ENES) http://enes.org representing the European climate modelling community and
- the world leading European Centre for Medium-Range Weather Forecasts (ECMWF) http://www.ecmwf.int
Due to the various complexities arising at exascale, the centre of excellence closely interacts with other HPC and exascale initiatives across Europe and beyond.
The governance structure that defines the services to be provided will be driven by its users - HPC architects and model developers of the European weather and climate science community; for details see answer (1) of the nine CoE questions. Weather and climate computing have always been one of the key drivers for HPC development, with domain specific scientific and technical requirements that stretch the capability and capacity of existing software and hardware to the limits.
By developing solutions for Europe and at European scale, ESiWACE will directly impact on the competitiveness of the European HPC industry by engendering new products, providing opportunities for exploitation beyond the project itself, and by enhancing the skills base of staff in both industry and academia. ESiWACE will be at once thematic, as it focuses on the HPC application domain of climate and weather modeling, transversal, as it covers several aspects of computational science, and challenge-driven, as climate and weather predictability represents a major societal issue.
