Code Review
This pull request updates the documentation for DeepSeek V3.1, providing new recommended parameters for a Prefill-Decode (PD) separation deployment. The changes include adjusting speculative decoding settings, GPU memory utilization, and compilation configurations, as well as introducing the VLLM_ASCEND_ENABLE_FLASHCOMM1 environment variable for communication optimization. A new 'Notice' section has been added to explain the core parameters, which greatly improves the clarity of the documentation. The changes are consistent across the different node configurations and appear to be well-considered. I have no concerns with this update.
