Mistral 助欧洲能源运营商将 4 万行 Fortran 77 迁移至 C++
一个真实案例：用 AI 代理迁移老旧的 Fortran 77 科学计算代码到 C++，关键是先搭建数值对拍框架，而非盲目翻译。
为迁移一套无测试、无文档的油藏模拟器，Mistral 先构建了数值一致性校验框架，再让 AI 代理分块翻译并重构。文章总结了如何证明新旧代码数值等价、如何拆分迁移任务，以及如何用代理加速这一过程。

Learn how it was done, and the lessons to carry forward. Legacy scientific codebases accumulate over decades, and when original authors leave, the knowledge embedded in the code becomes hard to recover. Moreover, using languages with no active developer ecosystem means missing out on the opportunity to build on top of others’ work. Mistral helped …
