project6-dev 8030a11b96 feat: 替换为 project_7 验证通过的 wudixzy stack
project_7 docker build 已在竞赛平台验证成功。
完整搬运 wudixzy/competition stack:
- qwen3_5.py 2615 行 (12 个 corex .so 调用)
- patch_ops.sh 251 行 (set -eo pipefail + cd dirname)
- 12 prebuilt corex .so (SHA256 verified)
- 13 CUDA .cu 源码 + 11 build scripts
- 9 vendor overrides (block/sampler/scheduler)
- transformers-4.55.3 offline wheel
- computility-run.yaml: 262144 max-model-len, BI100 env vars
- Dockerfile 结构不变 (COPY qwen3_6_scripts + RUN patch_ops.sh)
