|
||
|
||
> 记录 vllm-dspark、SGLang、vLLM 等后端在 DeepSeek-V4-Flash 上的 benchmark 脚本与最终结果。
|
||
|
||
## 目录说明
|
||
|
||
| 目录/文件 | 说明 |
|
||
|---|---|
|
||
| `scripts/` | 所有 benchmark 脚本、服务启动脚本、结果解析脚本 |
|
||
| `bench_results/` | 各次实验的最终产物：人可读 `.md` 报告 + 结构化 `results.json`（含原始数据与分位统计） |
|
||
| `BENCHMARK_WORKFLOW.md` | benchmark 目录与命名规范 |
|
||
| `scripts/SLO_STANDARDS.md` | 推理服务 SLO 标准（TTFT/TPOT） |
|
||
|
||
> 注：`.gitignore` 已排除 `envs/`、`deps/`、`tmp/`、`datasets/`、`logs/`、`*.zip`、原始 `raw_outputs/*.jsonl` 等大文件/中间文件。

||
## 快速复现
|
||
|
||
### DSpark grid
|
||
|
||
```bash
|
||
bash scripts/benchmark_dspark_0707/run_dspark_benchmark_grid.sh
|
||
```
|
||
|
||
### Spec-tokens 对比
|
||
|
||
```bash
|
||
bash scripts/benchmark_dspark_0707/run_dspark_st_comparison.sh
|
||
```
|
||
|
||
### 解析已有结果
|
||
|
||
```bash
|
||
/data/user1/yy/envs/sglang/bin/python scripts/benchmark_dspark_0707/parse_results.py \
|
||
/data/user1/yy/bench_results/dspark_grid_20260707-132641
|
||
```
|
||
|
||
## 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
|
||
|
||
- 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`
|
||
- 硬件：8× H200（当前配置）
