The rapid changes in the multiple supercomputing architectures used to run weather and climate codes and the different programming models used seriously affect the development productivity and the ability to retain a single source code running efficiently everywhere. Domain-specific languages provide a solution to portability of these codes. In this training, we provide insights into DSLs considered in ESiWACE2 (PSyclone, CLAW and GridTools ecosystem) and demonstrate how to apply them to weather and climate models.
Topics:
• Insights into PSyclone, CLAW and GridTools ecosystem
• Demonstration into how to apply them to weather & climate models
