||
## SLO 参考
|
||
|
||
详见 `scripts/SLO_STANDARDS.md`。
|
||
|
||
主要关注指标：
|
||
|
||
- **TTFT P95**：S2（DeepSeek-V4-Flash 所在层）目标 `< 3s`
|
||
- **TPOT**：S2 目标 `< 50ms`
|
||
|
||
## 环境要求
|
||
|
||
- **NVIDIA H200**：Python env `/data/user1/yy/envs/vllm-dspark`（服务端）、`/data/user1/yy/envs/sglang`（压测客户端）；模型 `/data/models/DeepSeek-V4-Flash`、`/data/models/DeepSeek-V4-Flash-DSpark`。
|
||
- **Kunlun P800**：Docker 镜像 `iregistry.baidu-int.com/xpu/sglang-p800-pd-disagg-0510:20260511_4202`；模型 `/data1/models/DeepSeek-V4-Flash-INT8`；压测客户端在容器内运行。
