From my understanding, head size 80 is only supported by backends that use PagedAttention (e.g. xformers, sdpa). None of those backends are supported in V1 yet.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

🚀

@LucasWilkinson what's the plan for supporting these head sizes in V1?

@LucasWilkinson what's the plan for supporting these head sizes in V1?

I think our best bet is to try and get these working via the triton backend:

Is there anything preventing triton attention from supporting head size 80 now?
