Description
Hi, just curious to know where the tensor parallel is implemented during inference.
In the inference/engine.py file, when replace_with_kernel_inject is set to False, does that mean TP will not be used during inference? And from my understanding, all_reduce is frequently called for TP, can you show me which part does this?
Thanks

Research direction
Start with inference/engine.py and trace the inference path when replace_with_kernel_inject is false. Search the inference implementation for tensor-parallel and all_reduce references, then document the relevant files and call sites. Done means a concise answer explains whether tensor parallel is used and where its collectives occur.
