 # sskj — 多平台大模型推理性能基准测试项目
 
+> **更新（2026-07-20 17:25:40 +0800）**
+> - RTX 6000D 的 SGLang DSV4-Flash 默认传入 `--cuda-graph-max-bs-decode 16`，避免 SM120 sparse MLA 在大 batch CUDA Graph 预捕获时 OOM。该参数仅限制预捕获图的 decode batch 上限，不限制服务的 `max-running-requests` 或 benchmark 并发；其他平台默认不受影响。
+> - H20、RTX 6000D、P800 的配置不再硬编码 sskj 仓库绝对路径：仓库内的环境、数据集、缓存和 P800 patch 均通过共享的 `${ROOT_DIR}` 推导，仓库迁移后无需逐个修改路径。
+
 > **更新（2026-07-20，PR 自动化测试）**
 > - 仅用于验证 Gitee 受保护分支的自动 Pull Request 创建与评审流程；不修改实验代码、配置或结果口径。
 
 > **更新（2026-07-20，`903084c`）**
-> - RTX 6000D 的 SGLang DSV4-Flash 默认传入 `--cuda-graph-max-bs-decode 16`，避免 SM120 sparse MLA 在大 batch CUDA Graph 预捕获时 OOM。该参数仅限制预捕获图的 decode batch 上限，不限制服务的 `max-running-requests` 或 benchmark 并发；其他平台默认不受影响。
 > - H20 / RTX 6000D 的 TPxDP matrix baseline 不再显式限制模型上下文或服务内并发：vLLM 使用默认 `max-model-len` / `max-num-seqs`，SGLang 使用默认 `context-length` / `max-running-requests`。
 > - SGLang 固定使用 `--moe-runner-backend marlin`；vLLM 保持框架默认 MoE backend。
 > - `run_adaptive_concurrency_add16.sh` 在首点 OOM 时会重启服务并按 `C=16 -> 8 -> 1` 回退；仅 H20 / RTX 6000D matrix 默认开启，H200 / P800 保持原行为。
