迁移步骤

通过适配层迁移

1. 将#include "HYPRE.h"改为#include "HYPRE_kp.h"，去除其余HYPRE相关头文件，若涉及ILU作为预条件子使用，需要去除HYPRE_ILUCreate、HYPRE_ILUDestroy和HYPRE_ILUSetMaxIter等相关预条件子创建及设置接口，BoomerAMG作为预条件子同理。
2. 在编译选项中将原先petsc的头文件路径和动态库路径修改为KML适配层的对应路径，并且重新编译应用，/PATH_TO_KML_INCLUDE为KML头文件路径，/PATH_TO_KML_ADAPTER为KML求解器适配器安装路径，/PATH_TO_KSCASOLVER为kscasolver安装路径，/PATH_TO_KBLAS为kblas安装路径，/PATH_TO_KM 为km安装路径。

   mpicc program.c -I /PATH_TO_KML_INCLUDE -L /PATH_TO_KML_ADAPTER -lHYPRE -L /PATH_TO_KSCASOLVER -lkscasolver -lkservice -lklapack_full -L /PATH_TO_KBLAS -lkblas -L /PATH_TO_KM -lkm -lm

   示例：

   mpicc program.c -I ~/HPCKit/latest/kml/gcc/include -L ~/HPCKit/latest/kml/gcc/lib/noarch -lHYPRE -L ~/HPCKit/latest/kml/gcc/lib/neon -lkscasolver -lkservice -lklapack_full -L ~/HPCKit/latest/kml/gcc/lib/neon/kblas/multi -lkblas -L ~/HPCKit/latest/kml/gcc/lib/noarch -lkm -lm

3. 添加环境变量。

   export LD_LIBRARY_PATH=/PATH_TO_KML_ADAPTER:/PATH_TO_KSCASOLVER:/PATH_TO_KBLAS:$LD_LIBRARY_PATH

   示例：

   export LD_LIBRARY_PATH=~/HPCKit/latest/kml/gcc/lib/noarch:~/HPCKit/latest/kml/gcc/lib/neon:~/HPCKit/latest/kml/gcc/lib/neon/kblas/multi:$LD_LIBRARY_PATH
