DescriptionWeather and climate is placed as one of the prime application domains for the incipient era of Exascale computing. The unprecedented amount of resources allows for the first time to perform simulations at the km-scale for climate time scales but poses huge challenges for developers of Earth system models, which are often comprised of large monolithic Fortran code bases. It incurs a need for large-scale refactoring, adaptation to new programming models and a transition to a scalable and sustainable development process that allows to continuously adapt to the rapidly developing portfolio of new hardware and software stacks.
