@kkHuang-amd Thanks for the contribution. Can you also take a look at attention kernels https://github.com/sgl-project/sglang/tree/main/python/sglang/srt/layers/attention/triton_ops?

@merrymercy my preliminary parameters search for attention/triton_ops did not lead to much better results from current settings. I hope @kkHuang-amd find it different.
