CUDA 12.8 added support for architectures `sm_100`, `sm_101` and `sm_120`,
while CUDA 12.9 further added `sm_103` and `sm_121`. To build for these,
maintainers will need to modify their existing list of specified architectures
(e.g. `CMAKE_CUDA_ARCHITECTURES`, `TORCH_CUDA_ARCH_LIST`, etc.)
for their package. A good balance between broad support and storage
footprint (resp. compilation time) is to add `sm_100` and `sm_120`.

Since CUDA 12.8, the conda-forge nvcc package now sets `CUDAARCHS` and
`TORCH_CUDA_ARCH_LIST` in its activation script to a string containing all
of the supported real architectures plus the virtual architecture of the
latest. Recipes for packages who use these variables to control their build
but do not want to build for all supported architectures will need to override
these variables in their build script.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

  • ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.

This message was generated by GitHub Actions workflow run https://github.com/conda-forge/conda-forge-webservices/actions/runs/16760507636. Examine the logs at this URL for more detail.
