Presentation
Global Storm Resolving Simulations in a Python Framework: An (early) Perspective from EXCLAIM
Presenters
DescriptionWithin EXCLAIM (EXtreme scale Computing and data platform for cLoud-resolving weAther and clImate Modeling), we are developing a performance-portable weather and climate model that resides within a Python framework. The model is based on the German global non-hydrostatic modeling system ICON.
Significant progress has been made in the last two years. Model components (i.e., dynamical core, tracer advection, and cloud microphysics) responsible for the model physics have been rewritten using an embedded DSL called GT4Py. The Python driver code that combines these physical components with the model infrastructure for a successful simulation is demonstrated to perform satisfactorily for a standard dynamical core test. Work is ongoing to expand the Python framework by including other model components. While there were several challenges along the way, the challenge that remains open is the missing connection with the conventional model developers which, by and large, is acting as an observer.
