Software Design Issue 📜

Purpose

Demonstrate 0.5 s per timestep at ~110 km resolution with 64 levels with all (but gravity wave) parameterizations on a single (A100) GPU.

The approach will be to tackle both egregiously expensive gpu kernels, improve parallelism where needed, and use kernel fusion to reduce sequential reads/writes.
