This PR adds basic support for AWQ by adding Triton implementations of awq_dequantize and awq_gemm to ROCm vLLM. Performance is not optimized and is quite slow, instead correctness is prioritized.

BEFORE SUBMITTING, PLEASE READ THE CHECKLIST BELOW AND FILL IN THE DESCRIPTION ABOVE

Notes for Large Changes

Please keep the changes as concise as possible. For major architectural changes (>500 LOC excluding kernel/data/config/test), we would expect a GitHub issue (RFC) discussing the technical design and justification. Otherwise, we will tag it with rfc-required and might not go through the PR.

What to Expect for the Reviews

The goal of the vLLM team is to be a transparent reviewing machine. We would like to make the review process transparent and efficient and make sure no contributor feel confused or frustrated. However, the vLLM team is small, so we need to prioritize some PRs over others. Here is what you can expect from the review process:

  • After the PR is submitted, the PR will be assigned to a reviewer. Every reviewer will pick up the PRs based on their expertise and availability.
  • After the PR is assigned, the reviewer will provide status update every 2-3 days. If the PR is not reviewed within 7 days, please feel free to ping the reviewer or the vLLM team.
  • After the review, the reviewer will put an action-required label on the PR if there are changes required. The contributor should address the comments and ping the reviewer to re-review the PR.
  • Please respond to all comments within a reasonable time frame. If a comment isn't clear or you disagree with a suggestion, feel free to ask for clarification or discuss the suggestion.

Thank You

Just a few minor things.

vllm/envs.py Outdated

# If set, vllm will print verbose logs during installation
"VLLM_USE_TRITON_AWQ":
lambda: bool(int(os.getenv("VLLM_USE_TRITON_AWQ", '0'))),

Can we do this as:

lambda: (os.getenv("VLLM_USE_TRITON_AWQ", "True").lower() in ("true", "1"))

(Make the default "True", to favor Triton.)

Oh yes, that makes sense for our repo.

split_k_iters, # Not used

Maybe remove the comment about "always being 128"... This should work for any reasonable value.

The group size is set when the model is quantized and it's always 128. I can update the comment though.

@hegemanjw4amd If our repo allows it, I'll just squash-merge, which will just result in one single commit for the whole PR.
