# CMU 暑研日报｜2026-07-24
## 中文摘要
今天的实质进展是研究问题、语义模型和证据门槛同时收紧。当前入口已从普通线程级 data race 推进为：**验证 warp-specialized GPU kernel 中异步硬件代理之间的 safety 与 progress，再连接到 functional refinement**。
### 关键变化
- **用户研究进展**：已向 Jia 教授和 Mengdi 发送四点更新及 `ProofWeaver_Research_Review_20260724.pdf`。这证明材料已形成并送达，不代表导师已经认可方法或正式立项。 - **语义模型**：execution、completion、visibility 分开建模，不再把所有同步统一压成 happens-before。 - **证据链**：必须先建立 source→PTX binding 与 runtime exact-instance binding，SMT 才能输出 verdict。 - **具体发现**：racecheck 可能产生 observer effect；engine–engine race 可能对动态工具不可见；lifecycle invariant 不能化约为局部 wait；局部 proof obligation 即使通过，whole-kernel verdict 仍可能必须保持 inconclusive。 - **协作**：Mengdi 提议下周一继续讨论，Ziwei 已同意；具体时间、Zoom/地点和日历邀请仍未确认。截止汇总时未检索到 Jia 教授回复。 - **Notion / Calendar**：没有发现今天新增或实质更新的 CMU Notion 页面；Google Calendar 中也没有下周一讨论或 7 月 27 日展示邀请。
### 节点与风险
1. **7 月 27 日口头展示 Session 1**：12:00 PM，GHC 7101，仍为 NOT CONFIRMED，距离 3 天。该事件与已延期的 Mixer 晚会是两件事。 2. **Mengdi 讨论**：已提议安排在 7 月 27 日，具体时间待定。 3. **住房**：当前住房 7 月 31 日结束。今天已说明计划看房，但尚无完成看房或签约证据；明天应确认房源、日期、价格与合同。 4. **Poster Session**：8 月 24 日 3:00–4:00 PM，GHC 7F Atrium，仍未确认。 5. **Mixer**：7 月 24 日直接提醒为 5:00–7:00 PM；是否参加未核验。日程表旧值为 5:30–7:00，采用直接提醒。7 月 27 日 Mixer 晚会已延期，不再按当天活动播报。
### 暑期计分板
- TOEFL：未记录 / 每周目标 2–3 天 - 健身：未记录 / 每周目标 2–3 次 - 实习记录本：baseline pending / 14 - 订阅：Target Circle 360 已确认关闭自动续费；其他订阅仍需逐项核验 - 杨老师展示：本周仍未收到已确认反馈
### 未来七天
- 7/25：Schenley Plaza Jubilee 11:00–18:00；Bakery Square Jazz 18:00–21:00（可选） - 7/27：Mengdi 讨论，时间待定；口头展示 Session 1 未确认 - 7/29：Paws to Relax 17:30–18:30（可选） - 7/31：当前住房结束；Carnegie Museum Trip 14:00–15:00（未确认）
### 下一步
确认下周一讨论时间；准备三个可判定的技术问题；将 source→PTX→runtime binding 写成最小验证流程；明日确认住房；继续把“用户提案”“导师反馈”“最终决定”分开记录。
## English Executive Summary
Today’s progress is a sharper research formulation. The target has moved beyond ordinary thread-level data races to **safety and progress across asynchronous hardware agents in warp-specialized GPU kernels**, followed by functional refinement.
Execution, completion, and visibility are now modeled separately. SMT may issue a verdict only after source-to-PTX binding and exact runtime-instance binding are established. Concrete findings include observer effects in racecheck, engine-to-engine races invisible to dynamic tools, lifecycle invariants that cannot be reduced to local waits, and whole-kernel cases that must remain inconclusive even when local obligations pass.
The four-point update and ProofWeaver review PDF were sent to Professor Jia and Mengdi. This is verified user progress, not advisor endorsement. Mengdi proposed continuing next Monday; the exact time and meeting link remain unconfirmed. No Jia reply was found by the cutoff.
