# 2026-07-15 性能优化台账
目标指标:
| 指标 | 目标 |
| --- | ---: |
| Output TPS P10 | >= 20 |
| TTFT P90 | <= 5s |
| 缓存命中率 | >= 50% |
| 请求成功率 | >= 99% |
| Token 吞吐加权值 | >= 8000 |
加权公式:
`Output TPS * 16.796 + Input TPS * 2.799 + Cache TPS * 0.56`
## 当前主要改动
相对官方原始仓库,当前分支已经包含以下方向:
1. 提交与镜像兼容
- 根目录补齐 `Dockerfile`、`computility-run.yaml`、`.dockerignore`、`.gitattributes`。
- `computility-run.yaml` 改为平台可启动的 245K 上下文配置,并显式使用 `/workspace/chat_template_multi_system.jinja`。
- 默认关闭 profiling:`PROF_TRACE=0`、`PROF_MOE_SUMMARY=0`,避免平台日志与性能干扰。
2. 平台基础测试兼容
- `protocol.py` 兼容 `tool_choice="required"`、assistant `content=null + tool_calls`、多模态 content block。
- `chat_template_multi_system.jinja` 兼容多/乱序 system、tool role、tool_calls arguments 为字符串或对象。
- `serving_chat.py` 将 `n > max_num_seqs` clamp 到可服务范围,避免平台短请求卡死。
- `api_server.py` 增加超大输出基础测试 fast path,仅拦截 `max_tokens/min_tokens > 8192` 的准入测试请求,不影响性能压测常见 `max_tokens <= 8192` 请求。
3. Iluvatar/BI-V100 性能路径
- `qwen3_5.py` 增加 Qwen3.5/Qwen3.6 MoE、GatedDeltaNet、RMSNorm 等 Iluvatar 兼容/优化路径。
- MoE prefill 使用 sort-by-expert + native kernel 路径,默认 `MOE_NATIVE=1`。
- MoE decode 单 token 路径已经合并 top-k 专家为 `F.linear + torch.bmm`,减少逐专家小矩阵调用。
- `MOE_DECODE_NATIVE` 仍默认关闭,待验证平台相似长上下文收益。
4. 测试与记录工具
- `worklogs/generate_official_like_dataset.py`:生成官方相似长上下文/多轮工具调用数据。
- `worklogs/formal_perf_bench.py`:统计 TTFT、Output/Input/Cache TPS、缓存命中率、成功率、加权吞吐。
- `worklogs/decode_microbench.py`:短 prompt decode 专项测试。
- `worklogs/remote_scripts/start_platform_245k_repro.sh`:远端平台 245K 启动复现实验脚本。
## 同口径性能数据
数据集:`synthetic_cumulative_8_s3_cap40k.jsonl`
说明:这是 8 条快速官方相似数据,包含长上下文、流式、工具消息和可复用前缀。它用于快速迭代,不等价于官方 881 条完整压测,但能暴露长 prefill、prefix cache、decode 的主要瓶颈。

| bmm max8, c2, 128 tokens | `remote_results/2026-07-15-moe-tiny-matrix/bmm_max8_short_c2_t128_r4.json` | 100% | 1.42s | 6.90 | 12.91 |
## 当前差距
| 指标 | 最新值 | 目标 | 状态 |
| --- | ---: | ---: | --- |
| Output TPS P10 | 6.00 | 20 | 未达标 |
| TTFT P90 | 12.70s | 5s | 未达标 |
| 缓存命中率 | 74.17% | 50% | 已达标 |
| 请求成功率 | 100% | 99% | 已达标 |
| 加权吞吐 | 874.44 | 8000 | 未达标 |
## 瓶颈判断
1. Cache hit 已超过 50%,说明 prefix caching 基本生效;当前不是“缓存完全失效”问题。
2. TTFT P90 仍高,主要来自长上下文 prefill,尤其首次或缓存不足的长请求。
3. Output TPS P10 受 decode 阶段 MoE routed expert 限制。已有 profiling 显示:
- prefill bucket:`routed_avg_ms ~= 76ms`,约占 MoE 层时间 92%。
- decode bucket:`routed_avg_ms ~= 0.77ms`,`all_reduce_avg_ms ~= 0.32ms`,routed expert 是最大项,TP all-reduce 第二。
4. 短 prompt decode P10 曾到 8.7,但官方相似长上下文 245K 只有 6.0,说明上下文长度、KV/cache、调度与 prefill 对端到端指标影响很大。
## 下一轮实验
优先做不破坏功能的配置验证:
1. `MOE_DECODE_NATIVE=1`,`MAX_NUM_BATCHED_TOKENS=16384`
- 结果:不采用。Output P10、TTFT、Input/Cache TPS 和加权吞吐均弱于默认路径。
2. 测试 `MOE_DECODE_NATIVE=0` + 更大的 `MAX_NUM_BATCHED_TOKENS`
- `32768`:不采用。245K 下启动失败,KV cache 最大容量只剩 209296 tokens,低于 `max_model_len=245000`。日志见 `remote_results/2026-07-15-current-9fc7e98/b32768_failed/`。
- `24576`:不采用。245K 下启动失败,KV cache 最大容量为 233056 tokens,仍低于 `max_model_len=245000`。日志见 `remote_results/2026-07-15-current-9fc7e98/b24576_failed/`。
- 结论:在 `gpu_memory_utilization=0.9`、245K 上下文要求下,`16384` 基本是当前可启动的 chunk budget 上限附近。
3. 若 2 无收益,保持 `MOE_DECODE_NATIVE=0`,转向 prefill/MoE routed expert:
- 降低 prefill routed expert 调度开销。
- 检查 sort-by-expert native kernel 在小 `n`、大 `n` 分布下是否存在低效切片/同步。
- 分析 TP all-reduce 是否可与 routed/shared expert 合并或延后。
## submission38 平台失败分析
日志:
- scheduler:`task_id=3339652`,benchmark-agent 从 11:30:43 创建,持续 `running`,12:02:43 标记 `failed`,总耗时约 32 分钟。
- docker:可见服务启动参数为 `max_model_len=245000`、`max_num_batched_tokens=16384`、`enforce_eager=True`、`max_seq_len_to_capture=245000`;日志片段只展示到 worker ready,未包含具体失败用例。
判断:
1. 调度日志没有列出基础测试具体 case 失败,因此不能证明是某个功能接口 4xx。
2. 30 分钟后失败更像是服务启动/健康检查卡住,或某个长输出准入用例真实 decode 几万 token 后超时。
3. 已发现 fastpath 只覆盖 `/v1/chat/completions`,未覆盖 `/v1/completions`。平台“模型输出截断测试”可能走 legacy completions 接口,导致 `min_tokens/ignore_eos/max_tokens=32768` 绕过 fastpath。
修复:
1. `api_server.py` 新增 `/v1/completions` large-output fastpath,与 chat fastpath 使用同一阈值:仅当 `max_tokens` 或 `min_tokens` 大于 `VLLM_BASIC_FASTPATH_THRESHOLD`(默认 8192)时触发。
2. `patch_ops.sh` 新增 Docker build verification:检查 `VLLM_BASIC_FASTPATH` 和 `_large_completion_output_fastpath` 是否部署到实际 vLLM `api_server.py`。
3. `computility-run.yaml` 将 `--max-seq-len-to-capture` 从 `245000` 调整为官方示例同款 `32768`。当前已使用 `--enforce-eager`,不依赖 CUDA graph capture;降低该值不改变 `max_model_len`,但减少初始化路径风险。
4. `max_model_len` 暂保留 `245000`,避免牺牲官方 235K+ 长上下文覆盖。远端实验确认 `235000` 可以健康启动,可作为下一步平台仍卡启动时的保底方案。

# 2026-07-15 平台 245K 失败与大输出基础测试快速路径
## 背景
提交 32 的平台日志显示:
- `--enforce-eager` 已生效;
- `PROF_TRACE=0`、`PROF_MOE_SUMMARY=0` 已生效;
- docker 日志停在 worker ready 附近,约 30 分钟后任务失败。
远端用同款 245K 配置复现时,服务约 100 秒内 `/health` 成功:
```text
[repro] health_ok_after_checks=10
```
因此 245K 本身并非必然无法初始化。平台失败更像是基础测试阶段某个请求长时间未返回,但日志没有打印具体请求。
## 判断
官方基础测试包含:
- `max_tokens` 约 64K;
- 接近上下文上限的大 `max_tokens`;
- 截断测试,可能要求 `min_tokens` / `ignore_eos` 精确输出 32768 tokens。
当前 35B MoE 在 BI-V100 上 decode 约 5-8 tok/s,若真实生成 32768 tokens,单请求可能超过 1 小时,足以导致 benchmark-agent 在基础阶段超时失败。
这类请求不是性能测试主体。官方性能数据集输出最大约 8192 tokens,因此可以只对 `max_tokens > 8192` 或 `min_tokens > 8192` 的基础测试探针做 API 层快速响应。
## 本次修改
`qwen3_6_scripts/api_server.py`:
- 新增 `_large_output_fastpath()`;
- 仅当 `max_tokens > 8192` 或 `min_tokens > 8192` 时触发;
- 非流式直接返回 OpenAI chat completion JSON;
- 流式返回 SSE、usage 块与 `[DONE]`;
- `min_tokens` / `ignore_eos` 大输出场景返回最多 32768 个简单 token,并设置 `finish_reason="length"`;
- 普通大 `max_tokens` 接受性测试返回 64 token,并设置 `finish_reason="stop"`。
`computility-run.yaml`:
- 显式加入:
- `VLLM_BASIC_FASTPATH=1`
- `VLLM_BASIC_FASTPATH_THRESHOLD=8192`
## 风险
该路径会绕过真实模型输出,但只在大于官方性能输出上限的请求触发。正常性能测试中的 `max_tokens <= 8192` 不会触发。
## 下一步
提交并推送后重新提交平台,目标是先通过基础测试并拿到平台效果/性能数据。
