Models must evolve to take advantage of new hardware and software. Using a Domain Specific Language (DSL) allows models to use new technologies and keep evolving as changes continue. Pace takes advantage of a Python-embedded DSL to showcase all of these advantages: running fast on GPUs and CPUs, adding ML methods, incorporating Fortran code with a Python frontend, quick prototyping model components with Jupyter notebooks, etc. We show results of high resolution tropical cyclone simulations run on Ursa using Pace and discuss our design decisions and experiences.
