[v2.6.x] Upgrade to CUDA 12.9 #405
Conversation
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. ref: https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#new-features

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 ( I do have some suggestions for making it better though... For recipe/meta.yaml:

Okay, so looks like the issue causing OSX builds to fail was addressed upstream in 2.7+ releases here. Created a patch and testing it. Will also test CUDA builds (I have access to a big GPU box to build on) |

Okay so #408 does fix the OSX build issue; however, seems a small number (4) tests are failing. @h-vetinari any chance we have logs from the linux builds? |
