STDD故障现场
[2026/6/1 15:20:52] at c: stdd 本地建 dev分支，开发 笔记 BsJqGgNFUTDK 上的需求
[2026/6/1 15:22:24] H02 - ARM: 需求已读取。现在探索当前代码结构，确认改动范围。
[2026/6/1 15:24:18] H02 - ARM: 现在创建 dev 分支，然后写 proposal。
[2026/6/1 15:24:20] at c: 开发过程中你可以需要 asset净值csv和factor因子csv，到时候问我要
[2026/6/1 15:25:36] H02 - ARM: Phase 1 — UNDERSTAND 完成，Gate 1 等待确认
变更：2026-06-01-factor-dual-chain
Why：当前 asset DataFrame 同时用于计价链路和分析链路，无法区分。因子数据与净值数据不同源时无法传入。
What Changes（6 处修改）：
plan_bt.py
• 改动: __init__ 加 factor 参数；init_asset_info → init_asset_info_factor 返回三元组；save_csv 存 factor.csv；plan_metrics/plan_plot 用 factor 做分析
port_bt.py
• 改动: __init__ 加 factor 参数，拆 _net_value/_factor；from_plan 透传；run() 计价用 _net_value，分析用 _factor
manager.py
• 改动: 无需改动
risk.py
• 改动: 无需改动
关键约束：
- factor 列名与 net_value 完全一致
- 默认 factor = asset（向后兼容）
- plan_plot 画图仍用 asset（净值），分析用 factor
Success Criteria：
- [ ] 默认调用（不传 factor）时，回测结果与修改前完全一致
- [ ] 传入独立 factor 时，计价链路用 asset，分析链路用 factor
- [ ] 输出目录包含 *_factor.csv
请确认 proposal 是否可以进入 Phase 2（SPEC）？
[2026/6/1 15:31:38] H02 - ARM: 好的，开发过程中需要数据时我会说。继续推进 Phase 2。
[2026/6/1 15:31:39] H02 - ARM: 📚 skill_view: "stdd"
[2026/6/1 15:33:04] at c: 确认
[2026/6/1 15:35:44] H02 - ARM: Phase 2 — SPEC 完成，Gate 2 等待确认
已生成以下文档：
design.md
• 说明: 技术设计 — 决策、架构、风险
specs/factor-dual-chain.md
• 说明: 行为规格 — 5 个 Scenario
test-plan.md
• 说明: 测试方案 — 8 个 TC，P0 优先
关键设计决策：
1. 在 PortBacktest 内部拆分为 _net_value（计价）和 _factor（分析）— 不改 Manager/Risk 接口
2. plan_metrics 分析用 factor，plan_plot 画图用 asset
3. 默认 factor = asset，向后兼容
风险最高项：计价链路 _net_value 替代 asset — 必须用真实数据回归确认结果一致。
请审阅以上设计文档，确认是否可以进入 Phase 3（SLICE）？
[2026/6/1 15:36:44] at c: 确认
[2026/6/1 15:38:45] H02 - ARM: ⏳ Working — 18 min — waiting for stream response (90s, no chunks yet)
[2026/6/1 15:54:15] H02 - ARM: 🔄 Primary model failed — switching to fallback: Qwen3.5-27B via v100
[2026/6/1 15:54:16] H02 - ARM: API call failed after 3 retries: Request timed out.
[2026/6/1 15:54:16] H02 - ARM: ⚠️ The model provider failed after retries. I kept raw provider details out of chat; check gateway logs for diagnostics.

PP速度: 49K token @ ~225 t/s (远低于此前小prompt记录的436 t/s)

→ task188876: 221.30s / 222.10 t/s (全程49K)
→ 每个2K chunk稳定在225-230 t/s，无衰减
HTTP断开: 3次 "Failed to read connection" (4356s/4358s/4360s)
→ llama-server timeout=3600远未到，是中继层先断

PP 225t/s的重新解读:
progress=0.58时n_tokens=49152 → ctx-size=262144, 0.58×262144≈152K
已有缓存 ≈152K−49K=103K (来自多轮对话历史)
flash-attention下PP计算量随总上下文增长，不是只算新token
空缓存下49K PP: 注意力∫₀^{49K}=1.2B units
已有103K缓存下49K PP: ∫_{103K}^{152K}=6.25B units → ~5×计算量
实测225t/s vs 空缓存小prompt 436t/s 是预期的，非配置退化
与ini注释"12核2048/512: 50K pp300"相比差~25%，这部分可能来自GPU1未参与
时序分析:
task188844: 4354s起PP → 4356.44s第1次断(20K处) → 继续 → 4358.46s第2次断(47K) → 4358.19s完成
task188876: 4358.38s起PP → 4360.53s第3次断(25K处) → 4362.10s完成
两次断开间隔 ~220s，说明客户端超时约180-240s
显存修正: nvitop是空闲时采样(16:04:24)，PP时GPU Util未知
GPU0 14294MiB占用含：模型权重+KV cache+缓存上下文103K
GPU1 13834MiB占用：模型权重+KV cache的GPU1部分
实际瓶颈圈定:
① FRP ✅ 没问题(1200s超时)
② Nginx proxy_read_timeout? 不确定
③ Hermes gateway HTTP timeout? 需查ARM端
④ 即使排除超时问题，~220s PP对STDD这种需要多次往返的工作流也难接受
排查记录3
网络路径已确认:
v1008080.atibm.com → 本宿主机(ARM) → Docker net → nginx(容器) → frps → frpc → llama-server(127.0.0.1:54473)
nginx frps.conf关键配置:
server_name ~^v100808\d\.atibm\.com$;
proxy_pass http://frps:8080;
proxy_buffering off;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_connect_timeout 300s;
proxy_send_timeout 300s;
proxy_read_timeout 300s;
结论: Nginx proxy_read_timeout=300s, PP仅220s → Nginx ✅ 也不是瓶颈！
三层中继已全部排除:
✅ llama-server timeout=3600 (>220s)
✅ FRP vhostHTTPTimeout=1200 (>220s)
✅ Nginx proxy_read_timeout=300 (>220s)
更精确断开时间(t=累积PP耗时):
task188844 第1次断: ~20K token处 t≈90-100s
task188844 第2次断: ~47K token处 t≈210-220s
task188876 第1次断: ~25K token处 t≈108-118s
全部 <300s, nginx不可能触发超时
断开一定来自客户端(Hermes agent)层面。
V100 provider无显式request_timeout_seconds配置(env var方式),
HTTP客户端使用默认超时值
排查记录4
llama.cpp升级: 旧版(?) → version 9449 (e22b0de60)
升级前: TG 63 t/s, PP 273 t/s (layer, 0.87,1, reasoning=on)
升级后: TG 103 t/s, PP 573 t/s ✅ 恢复基线
split-mode测试结论 (2×V100, MoE模型Qwen3.6-35B):
layer模式: TG 103 t/s, PP 573 t/s ✅ (适用MoE, pipeline通信少)
row模式: TG 34 t/s, PP 210 t/s ❌ (MoE每层多次all-reduce, NVLink扛不住)
tensor模式: MoE不支持, 不可用
layer模式的tensor-split = 0.87,1:
目的: 补偿GPU0嵌入表~1GB + CUDA context~0.5GB的固定开销
row模式也需要tensor-split调平衡, 但嵌入表钉GPU0、MoE+row的TG损耗不可接受
→ layer + tensor-split=0.87,1 是这套硬件的正确组合
nvitop空闲采样问题:
GPU1 Util 0%只代表采样时刻无任务, 不代表PP时GPU1不参与
layer模式下GPU1参与KV cache读取和解码, TG时两张卡都在工作
100 t/s基线的条件:
12核 + 2048/512 batch/ubatch + reasoning=on + llama.cpp 9449
旧版本(llama.cpp 9449之前)会掉到63 t/s
仍然待确认:
Hermes agent V100 provider的HTTP客户端默认超时值
→ 修复: hermes config set providers.V100.request_timeout_seconds 600
