This PR will accomplish the following tasks: **optimize SP** In the old version implementation, the first layer was all_reduce, which used rms to split chunks. We changed it to perform reduce_scatter on the embedding side, replace one all_reduce operation and one chunk with one reduce_scatter operation. **Support qwen3 next** Since Qwen3 Next includes a linear attention module, the prefix name of this module cannot take effect directly. - vLLM version: v0.11.0rc3 - vLLM main: https://github.com/vllm-project/vllm/commit/v0.11.0 --------- Signed-off-by: weijinqian_v1 <weijinqian@huawei.com> Co-authored-by: weijinqian_v1 <weijinqian@huawei.com>
