Question

我按如下所示安装了openmpi-4.0.0（https://www.open-mpi.org/software/ompi/v4.0/）

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/redux/4.0.1/redux.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-redux/6.0.0/react-redux.min.js"></script>
<div id="root"></div>

然后在包中输入示例文件夹，并使用命令：

./configure --prefix="/usr/local/openmpi"
make
sudo make install
export PATH=$PATH:/usr/local/openmpi/bin 
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openmpi/lib/
source ~/.bashrc  
sudo ldconfig

它显示：

make
mpirun -n 4 ./hello_usempi

问题似乎只有一个处理器被激活。请注意，我的计算机上同时安装了openmpi-4.0.0和Ifort。任何人都可以帮我一下，谢谢。

我在此处添加命令Hello, world, I am 0 of 1: Open MPI v2.1.1, package: Open MPI buildd@lcy01-amd64-009 Distribution, ident: 2.1.1, repo rev: v2.1.0-100-ga2fdb5b, May 10, 2017 Hello, world, I am 0 of 1: Open MPI v2.1.1, package: Open MPI buildd@lcy01-amd64-009 Distribution, ident: 2.1.1, repo rev: v2.1.0-100-ga2fdb5b, May 10, 2017 Hello, world, I am 0 of 1: Open MPI v2.1.1, package: Open MPI buildd@lcy01-amd64-009 Distribution, ident: 2.1.1, repo rev: v2.1.0-100-ga2fdb5b, May 10, 2017 Hello, world, I am 0 of 1: Open MPI v2.1.1, package: Open MPI buildd@lcy01-amd64-009 Distribution, ident: 2.1.1, repo rev: v2.1.0-100-ga2fdb5b, May 10, 2017和mpif90 -v的消息

makefile的内容很长，我认为在此处发布不方便，它仍在OpenMPI-4.0.0的安装包中。再次谢谢你。
