PowerPC packages

They are missing right now. When available, the conda_build_config.yaml file in nvcc-feedstock will need to be updated.

I have a question for @jakirkham @kkraus14: Why do we have to zip cudnn with nvcc versions? We don't do this for other CUDA libraries (nccl, cutensor, ...). It seems inconvenient and error-prone to me to treat cudnn differently.

IIUC that was added in PR ( conda-forge/conda-forge-pinning-feedstock#1051 )

cc @isuruf (in case you have thoughts here)

IIRC it's because certain CUDA versions only support cuDNN 7 whereas other CUDA versions only support cuDNN 8

I think for this case the pinning is better done via run_exports in the recipe.

On the ppc64le support: The last release that contained a downloadable archive for ppc64le + CUDA 10.2 is 8.0.5. After that, all ppc64le packages are released only for CUDA 11.0+, which we do not support here yet. Should we create a new breach to package 8.0.5 for ppc64le?

[jakirkham]

Sure that seems reasonable

OK thanks @jakirkham. Could you create a new branch for me against which I can send a PR? I am not yet a maintainer here.

Manually done in #25.
