This commit adds support for CUDA 13.x versions in the ptx_get_version function. Previously, CUDA 13.0 would raise a RuntimeError saying 'Triton only support CUDA 10.0 or higher', even though 13.0 > 10.0. The fix maps CUDA 13.0+ to PTX version 8.9+, following the existing pattern for CUDA 10.x (PTX 6.3+), 11.x (PTX 7.0+), and 12.x (PTX 8.0+). Note: A separate fix is needed for PTX version mismatch where the .version directive should match the actual PTX features used by LLVM (capped at 8.3). This may need to be applied in C++ code or Python wrapper depending on repository structure. Fixes Windows build issues with CUDA 13.0.

There was a problem hiding this comment.
we are preparing a proper update to cuda 13.1 coming up next week. Adam is going to send a PR soon updating ptxas and fixing few things

I am not making a trivial change, such as fixing a typo in a comment.
I have written a PR description following these

littests.littests I have added follow these best practices,including the "tests should be minimal" section. (Usually running Python code
and using the instructions it generates is not minimal.)
