A3 910C 有16 dies(8卡x2die),H20有8卡。为公平对比,TP按卡数等效: A3 TP=4 DP=4 (4die/副本x4) == H20 TP=2 DP=4 (2卡/副本x4) A3 TP=8 DP=2 (8die/副本x2) == H20 TP=4 DP=2 (4卡/副本x2) A3 TP=16 DP=1 (16die/副本x1) == H20 TP=8 DP=1 (8卡/副本x1) 与dsv4实验(a65849b)保持一致的配置思路。 新增TP=4 per-TP参数覆盖(expert-parallel下专家分4份+dense复制, KV cache极紧): gpu_mem=0.97, max_model_len=4096, max_num_seqs=32 TP=4可能OOM,若发生会自动记录并跳过。 config.env: PARALLEL_CONFIGS 8 1/16 1 -> 4 4/8 2/16 1; 加TP4_变量 start_vllm_docker.sh: case $TP 加 TP=4 分支 run_adaptive_concurrency_add16.sh: case $tp 加 TP=4 分支

# TP×DP matrix experiment for GLM-5.2 on Ascend 910C (8 NPUs / 16 dies) using vLLM-Ascend.
