Is there a publicly released version of CESM based on GPUs?

Dear community,

Is there a publicly released version of GPU-based CESM? It seems that CESM2 is CPU-based. Which repository and guide should I refer to if I'm running CESM on a GPU machine?

Best,
Xin

Thanks for writing, Xin. I believe GPU-enabled code is a CESM3 new development (Community Earth System Model 3 (CESM3): Plans, progress, timelines | Community Earth System Model) so it would be present in the upcoming CESM3 release.

I will move this thread to the infrastructure forum.

Thank you very much for the information! We will follow up on CESM3 progress and look forward to the new release soon!
