In our new paper, we demonstrate for the first time that it is indeed possible* to use LES to reconstruct real-world ABLs in a way where you can track the observed large eddies (on the ~1 second timescale and ~10 m spatial scale).

*possible, but currently woefully impractical and kinda hacky

Gosh, smoke stacks can be so satisfying in the winter. This plume 😍 It basically just slides from left to right---doesn't go up, and the clouds don't tumble either

Playing around with memory-saving techniques today, and I'm blown away by Activation Checkpointing. Dropped my VRAM requirements from 22 GB to 7 GB with a single line of code. Slowed the run down by 33%, but totally worthwhile

New week, new profiling tool! Futzing around with NVIDIA Nsight Systems now

Dipping my toes into ML code performance profiling, wish me luck. Any tips would be much appreciated! #pytorch
