-# GLM-5.2 W4A8 P800 single-node benchmark
+# GLM-5.2 W4A8 P800 single-node smoke benchmark
 
-- Validated hosts: `sskj-P800-2` (`gpu049`) and `sskj-P800-4` (`gpu051`)
+- Host: `sskj-P800-4` (`gpu051`)
 - Image: `iregistry.baidu-int.com/xpu/sglang-p800-pd-disagg-0510:20260715_5746`
-- Default model: `/data2/glm52_deploy/models/GLM-5.2-w4a8`
+- Model: `/data2/GLM-5.2-w4a8`
 - Parallelism: TP=8, EP=8, DP=1
 - Quantization: `w4a8_int4`; KV cache: `int8`
-- Default dataset: `/data2/ShareGPT_V3_unfiltered_cleaned_split.json`
+- Dataset: `/data1/wxy/sskj/datasets/ShareGPT_V3_unfiltered_cleaned_split.json`
 - Benchmark: ShareGPT, 64 prompts, concurrency 8, output length 128, request rate unlimited
 
 Run `bash start_glm52_w4a8.sh`, wait for `http://127.0.0.1:30000/health`, then run `bash run_bench.sh`.
-
-The launcher accepts environment overrides so that tuning runs change one
-variable at a time. Supported knobs include `CUDA_GRAPH_MAX_BS`,
-`CHUNKED_PREFILL_SIZE`, `MAX_PREFILL_TOKENS`, `MEM_FRACTION_STATIC`,
-`MAX_RUNNING_REQUESTS`, `KV_CACHE_DTYPE`, and `ENABLE_SPECULATIVE`.
-
-Run the fixed four-point tuning smoke suite with:
-
-```bash
-RUN_ID=<name> bash run_tuning_smoke.sh
-```
-
-For EAGLE/MTP, start the service with `ENABLE_SPECULATIVE=1`. The default
-speculative settings follow the vendor deployment document: 3 steps, top-k 1,
-and 4 draft tokens.
