Weather and climate kernel performance and energy models, integrated in the DCworms simulator, project time-to-solution and energy-to-solution for CPU and hybrid CPU+GPU systems, with validation errors of roughly 8 to 23 percent.
The Legendre transform has computational complexity of O(N2) which increases with horizontal resolution
