…63988) See also #163972, which was intended to be this PR. Triton (release/3.5.x) by default ships CUDA12.8 ptxas. This PR tries to bundle a ptxas version for cuda13, so that it can help #163801 when users run on new devices like THOR and Spark. Fixes #163801 Test Plan: Check binary size increase against nightly or v2.9RC Install the binary from into a working THOR and GB200/GH100 machine (reproduce the original issue first on THOR), then install the binary built from this PR and we expect the issue to be gone without any additional user setting. Testing on GB200 is to ensure no regression. Reference: #119750 and pytorch/builder@5c814e2 Note: with this PR, the pytorch world's torch.compile is supposed to find ptxas via "torch/_inductor/runtime/compile_tasks.py" and "_set_triton_ptxas_path". Use cases that do not go through "_set_triton_ptxas_path" may not be able to use the cuda13 ptxas binary. However, as is, the triton world does not know the existence of this new cuda13 ptxas. So IF a users thinks there is already pytorch/bin/ptxas and delete the ptxas from triton, then https://github.com/triton-lang/triton/blob/c6ad34f7eb42630533412d93ca2cc00a4b4f8f3c/python/triton/knobs.py#L216 would still complain ptxas not found (if removed - it won't know this new one available) Pull Request resolved: #163988 Approved by: https://github.com/atalman (cherry picked from commit 3b4ad4a)
