"Yes, PyTorch's scaled dot product attention can run on AMD GPUs. PyTorch supports AMD GPUs through the ROCm (Radeon Open Compute) platform. To use PyTorch with an AMD GPU, you need to install the ROCm version of PyTorch, which is specifically built for AMD GPUs [...]"
And it proceeded to give the steps to follow to install and run, with example Python code to demonstrate it. One slight nitpick is that it referred to an older URL with the --index-url to install torch with pip, but otherwise it was correct.
I don't quite understand this argument. Lack of transparency from running PyTorch so instead we're gonna leave it all to XLA? How does this solve the "transparency" issue?
Moreover, this will get worse as more CUDA specific features are added to PyTorch with ad-hoc fallback functions.
I guess OP is saying that XLA is more transparent in this regard, because it wouldn’t use functions like these and the generated comparable code would be on-pare performance wise?
Perhaps if XLA generated all functions from scratch, this would be more compelling. But XLA relies very heavily on pattern-matching to common library functions (e.g. CuDNN), and these patterns will certainly work better on Nvidia GPUs than AMD GPUs.
In this way, I actually think explicitly calling the common library functions is actually much more transparent.
And was trying to make a broader point about the lack of transparency (in performance, lower-level impl) in PyTorch when running on NVIDIA vs. non-NVIDIA hardware.
