OpenMPI安装教程
摘要
本文介绍如何在CentOS7.6系统上使用Intel2018.4编译器安装OpenMPI1.10.7和OpenMPI3.1.4
OpenMPI1.10.7
安装命令
./configure --prefix=`pwd`/install --enable-orterun-prefix-by-default CC=icc CXX=icpc FC=ifort CFLAGS="-xHost -O3 -ip" CXXFLAGS="-xHost -O3 -ip" FCFLAGS="-xHost -O3 -ip" LDFLAGS="-Wc,-static-intel" --with-ucx=/usr
make -j
make -j check
make -j install-enable-orterun-prefix-by-default：可以让运行时不用指定prefix
-Wc,-static-intel：可以静态链接intel的一些库，以防运行OpenMPI的指令时找不到库
--with-ucx=/usr：是OpenMPI1.10.7的bug，不加会在编译过程中出现如下的
libtool: error: require no space between '-L' and '-lrt'
make[2]: *** [libmca_pml_ucx.la] Error 1最后配置modulefile
OpenMPI3.1.4
./configure --prefix=`pwd`/install --enable-orterun-prefix-by-default CC=icc CXX=icpc FC=ifort CFLAGS="-xHost -O3 -ip" CXXFLAGS="-xHost -O3 -ip" FCFLAGS="-xHost -O3 -ip" LDFLAGS="-Wc,-static-intel"
make -j
make -j check
make -j install-enable-orterun-prefix-by-default：可以让运行时不用指定prefix
-Wc,-static-intel：可以静态链接intel的一些库，以防运行OpenMPI的指令时找不到库
如果没有事先安装zlib库的话，还需要安装zlib，并在configure中的LDFLAGS中添加：-L/path/to/zlib-1.2.11/build-2018u4/lib
最后我的configure结果如下
