问题描述

我正在尝试安装openmpi，但是经过不同的尝试后，我仍然无法使用它.

I'm trying to install openmpi but after different attempts I still can't use it.

这是

This is the last guide I followed. I simply copied and paste each command line.

这是我从终端上获得的内容:mpirun

Here is what I obtained from my terminal when I run: mpirun

timmy@timmy-Lenovo-G50-80 ~/openmpi-1.8.1 $ mpirun

所以我重新启动，现在我只得到这个:

So I reboot and now I obtain only this:

mpirun: error while loading shared libraries: libopen-rte.so.12: cannot open shared object file: No such file or directory

要在Linux上运行mpi，我需要做什么?

What I have to do to make works mpi on linux?

推荐答案

您需要将LD_LIBRARY_PATH设置为包含/home/timmy/.openmpi/lib.具体来说，您必须将所遵循的指南中的这两行放在其中:

You need to set your LD_LIBRARY_PATH to include /home/timmy/.openmpi/lib. Specifically, you have to put those two lines from the guide you've followed:

export PATH="$PATH:/home/$USER/.openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/"

进入外壳的初始化文件.

into your shell's initialisation file.

关于第一个错误，它发生在Open MPI的mmap shmem组件初始化期间的某个地方，可能表明您的构建有问题.尝试删除/home/timmy/.openmpi并再次重建.甚至尝试使用系统的程序包管理器安装该库-几乎每个发行版的程序包存储库中都提供了或多或少的Open MPI版本.

As to the first error, it occurs somewhere during the initialisation of the mmap shmem component of Open MPI and could indicate problems with your build. Try removing /home/timmy/.openmpi and rebuilding again. Or even try installing the library using your system's package manager - a more or less recent version of Open MPI is available in the package repository of virtually every distribution.
