在本地安装 OpenMPI 以与 CUDA 一起使用时出现问题
Problems installing OpenMPI locally for use with CUDA
精简版
我有 CUDA 代码，我需要在本地 运行。因此，我正在尝试在 the OpenMPI directions. When I try to make my code, I receive very long error output, similar to what is described by the OpenMPI documentation 之后安装 OpenMPI。我尝试使用文档建议的修复方法重新安装 OpenMPI，但现在我在安装过程中遇到了这些错误：

我有 CUDA 代码，我需要在本地 运行。因此，我正在尝试在 the OpenMPI directions 之后安装 OpenMPI。我将 tar 存储为 ~/Downloads/openmpi-2.1.1.tar.gz。汉斯，我 运行
$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。请注意，我将方向中的 --prefix=/usr/local 更改为 --prefix=/opt/openmpi-2.1.1。我包括了 configure_log1 and install_log_take1.
当我尝试使用我的 makefile make 我的代码时 makefile.ulfhednar,
$make -f makefile.ulfhednar clean
$make -f makefile.ulfhednar &> make_log1
我在 make_log1 that looks similar to what is described by the OpenMPI documentation 中收到很长的错误输出。它说解决方案是使用配置选项“./configure CC=icc CXX=icpc F77=ifort FC=ifort ...”安装 OpenMPI，所以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

这里是configure_log2 and install_log_take2。 install_log_take2 中值得注意的是以下几行：

抱歉，我必须将所有日志文件上传到 mediafire，pastebin 不接受它们，因为它们太大了。

我找到了解决办法！！！
我在没有使用 sudo 的情况下通过安装步骤登录了 root 和 运行。
#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
我试图将 OpenMPI 与英特尔 Composer 编译器一起使用，这导致了权限问题。我按照 here 中的安装说明进行操作，但在尝试安装时遇到了与之前相同的问题。问题是链接器 ld "could not find" 正确的库，因为当调用 sudo 时，$LD_LIBRARY_PATH 变量中不再提供这些库。避免这种情况的唯一方法是登录 root 用户并将您的 $LD_LIBRARY_PATH 变量设置为与您的普通用户相同。
我已经在这个问题上坚持了天，现在它已经解决了，我高兴得跳了起来！我希望这对以后的其他人有所帮助。
