OSX M1, M2 support?

[lukasc-ubc]

Hello,

I am wondering if fdtd-z works on Mac OSX M1 or M2 computers running the ARM64 processor?

The CUDA toolkit is required, and it sounds like it is not completely supported: link. Namely, there is no NVIDIA GPU in the AMD apple computers...

Mac has Metal for ML tasks, and supports Jax. I wonder if that could be used?

Hi Lukas! Unfortunately, the implementation of fdtd-z is very intimately tied to the architecture of Nvidia GPUs. Even if fdtd-z could somehow run on other platforms, there would be virtually no chance that it would be performant.

Thanks Jesse, I came across a Mac Metal implementation of FDTD. It looks like this CPU/GPU is quite promising in terms of performance: https://github.com/ProteusMRIgHIFU/BabelViscoFDTD <https://github.com/ProteusMRIgHIFU/BabelViscoFDTD>

Hi Lukas,

i found the easiest way to run fdtdz is using Google Colab
