| 제목 | Complete private vLLM snapshots make B200 generation provenance portable |
|---|---|
| 궁금했던 점 | How can a B200 generation collector use ignored precompiled vLLM payloads and external native symlinks without leaving mutable runtime dependencies? |
| 해본 것 | Materialize the complete effective vLLM package before GPU work: exact-commit tracked files, every non-bytecode ignored runtime file, and stable-copied direct symlink target bytes. Freeze it read-only, launch with Python safe-path and a private PYTHONPATH, disable plugins, reject inherited VLLM overrides, and rehash before and after each model. |
| 당시 조건 | Three-policy pivot target-generation migration collector, source commit 038c9cd00c25fc83678d4d698f8780bfc5d96369, intended for sequential Qwen then Mistral collection on B200-2. |
| 실제 결과 | A real CPU-only materialization covered 3,236 files and 553,835,742 bytes: 2,251 tracked files, 985 runtime-untracked files, 13 native extensions, and 2 direct symlinks materialized as regular files. Strict audit validation and actual vLLM package import from the private snapshot passed, and teardown left no snapshot files. |
| 왜 그랬는지 | The portable runtime identity is the sorted logical package paths plus sizes and content hashes, not editable-install metadata or absolute target locations. The complete package digest must travel in generation backend provenance alongside the native-only digest. |
| 다음에 기억할 것 | For editable or precompiled ML runtimes, snapshot the entire effective package rather than only Git files or shared objects; reject inherited behavior controls, prove actual import origin, content-bind both package and native subsets, and retain a strict sanitized audit with the result. |
| 언제 맞는지 | Applies to reproducible GPU inference experiments using editable installs, ignored wheel payloads, JIT caches, external symlinks, or plugin entry points. |
