If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
稀疏矩阵数据结构
图论重排序算法
并行LU分解
C++17与DLL接口
多核CPU性能优化
开源许可证合规
The real friction is usually not library usage. It is validation, time allocation, and task framing.
核心难点不是单独找到一种矩阵重排，而是在高度稀疏且结构不均衡的约6万变量方程组上，让重排后的矩阵既适合并行LU分解，又尽量避免各线程子块工作量失衡。作品还要在指定调用环境中以“预重排+LU分解”的总耗时竞争，并提供可复现源码、DLL、可视化工具和映射关系。
