Seems this is likely due to ongoing work on FP8 support on nvidia/cutlass. From my reading, the alternative code path was likely added recently for testing by external contributors to the cutlass project, and other involved parties. (Rather than attempting to distribute custom packaged internal builds of cuda.) This ticket is a good starting place to see the chain of issues around the ongoing work: https://github.com/NVIDIA/cutlass/pull/2037 https://github.com/NVIDIA/cutlass/pull/2037
