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

   14 | #include "HYPRE_sstruct_mv.h"

没有MPI头文件：

   20 | #include "mpi.h"
      |          ^~~~~~~

没有链接mpi库

/usr/bin/ld: pcg.c:(.text+0xf58): undefined reference to `sqrt'

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
