天河超算，安装Hypre
1)下载，解压
略
得到目录：hypre-master
源文件在src目录下面
src包含如下目录：
2）cmake编译
版本比较新
HYPRE_RELEASE_NAME = hypre
HYPRE_RELEASE_VERSION = 2.26.0
HYPRE_RELEASE_DATE = 2022/10/14
HYPRE_RELEASE_TIME = 00:00:00
HYPRE_RELEASE_BUGS = https://github.com/hypre-space/hypre/issues
./configure
cd cmbuild
cmake ..
make
生成了：
6564172 Nov 28 11:30 libHYPRE.a
3）编译例子
cd hypre-master/src/test
make会出错

还有sin, cos没有的
解决方法：
修改 config/Makefile.config
107 ##################################################################
108 ## MPI options
109 ##################################################################
110 MPIINCLUDE = -I/thfs1/software/mpich/mpi-n-gcc9.3.0/include
111 MPILIBDIRS = -I/thfs1/software/mpich/mpi-n-gcc9.3.0/lib
112 MPILIBS = -lmpi
113 MPIFLAGS =
上面是mpi的头文件，库，及链接函数等
加了-lm
缺少Hypre本身的头文件，可能需要同样配置这个config/Makefile.config
由于-I/thfs1/home/***/hypre-master/src/hypre/include
所以我是把所有的相差的.h, .hpp去cp到/thfs1/home/***/hypre-master/src/hypre/include 这个目录下。
4）
make
生成了各种可执行文件
运行./ij_mm
输出 没有问题

看起来没有问题。
