C++ 在本地安装OpenMPI以便与CUDA一起使用时出现问题 短版

我有CUDA代码，需要在本地运行。因此，我尝试安装以下OpenMPI。当我尝试

make

我的代码时，我收到了类似于。我尝试使用文档建议的修复程序重新安装OpenMPI，但现在在安装过程中出现以下错误：

我做错了什么？请帮忙！S.O.S

长版本 我有CUDA代码，需要在本地运行。因此，我尝试安装以下OpenMPI。我将tar存储为

~/Downloads/openmpi-2.1.1.tar.gz

。汉斯，我跑了

$gunzip -c openmpi-2.1.1.tar.gz | tar xf -
$cd openmpi-2.1.1
$./configure --prefix=/opt/openmpi-2.1.1 &> configure_log1
$sudo make all install &> install_log_take1

成功了。注意，我将方向中的

--prefix=/usr/local

更改为

--prefix=/opt/openmpi-2.1.1

。我已经包括和

当我尝试使用我的makefile制作我的代码时

我收到了一个很长的错误输出，看起来与。它说解决方案是安装带有配置选项“

/configure CC=icc CXX=icpc F77=ifort FC=ifort…

”的OpenMPI，因此我使用命令重新安装

$cd ~/Downloads/openmpi-2.1.1
$sudo make uninstall
$sudo rm -r /opt/openmpi-2.1.1
$cd ..
$sudo rm -r openmpi-2.1.1

$gunzip -c openmpi-2.1.1.tar.gz | tar xf -
$cd openmpi-2.1.1

$which icc
/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/icc
$which icpc
/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/icpc
$which ifort
/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/ifort

$./configure --prefix=/opt/openmpi-2.1.1 CC=/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/icc CXX=/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/icpc F77=/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/ifort FC=/opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/ifort &> configure_log2
$sudo make all install &> install_log_take2

这是和。请注意

install\u log\u take2

中的以下几行：

很抱歉，我不得不将所有日志文件上载到mediafire，pastebin不接受它们，因为它们太大了

我做错了什么？请帮忙！S.O.S

我找到了解决办法

我登录到

root

并在不使用sudo的情况下完成了安装步骤

#gunzip -c openmpi-2.1.1.tar.gz | tar xf -
#cd openmpi-2.1.1
#./configure --prefix=/opt/openmpi-2.1.1 CC=icc CXX=icpc FC=ifort
#make all install

我试图在英特尔Composer编译器中使用OpenMPI，这导致了权限问题。我按照找到的安装说明进行了安装，但我遇到了与以前尝试安装时相同的问题。问题是链接器，

ld

“无法找到”正确的库，因为调用

sudo

时，

$ld\u LIBRARY\u PATH

变量中不再提供这些库。绕过此问题的唯一方法是登录到

root

用户并将

$LD\u LIBRARY\u PATH

变量设置为与普通用户相同

我已经坚持了好几天了，现在事情解决了，我高兴得跳了起来！我希望这对将来的其他人有所帮助

#gunzip -c openmpi-2.1.1.tar.gz | tar xf -
#cd openmpi-2.1.1
#./configure --prefix=/opt/openmpi-2.1.1 CC=icc CXX=icpc FC=ifort
#make all install
