@SamDeAbreu see the documentation on setting up distributed grids here: https://clima.github.io/OceananigansDocumentation/stable/grids/ No other changes are required for simple set ups, but your mileage may vary depending on your case. Let us know how this goes (and if you provide the script you are trying to run on multiple GPUs, that may help). |

Hi everyone!
I wanted to ask if it is possible to run a simulation parallelized over CPU/GPUs with irregular grid spacing in one direction? I've seen this which stated that this wasn't possible yet due to the need of a distributed FFT. It seems now there is a distributed tridiagonal Fourier solver (#3689), but I believe there is no documentation on how to get started in setting up such a simulation. My intention is to run this on an HPC eventually.
Any insight would be greatly appreciated!
