并行组设置& mpi4py / OpenMDAO 2.2.X

标签: openmdao

我正在尝试使用mpi / openmdao的并行化。

我尝试过各种ubuntu计算机以及windows上的ubuntu bash(Windows 10功能)

依赖项独立工作正常(即import petsc4py和import mpi4py工作正常,我可以运行类似于链接的测试:https://openmdao.readthedocs.io/en/1.7.3/getting-started/mpi_linux.html& http://mpi4py.scipy.org/docs/usrman/install.html

但是Paralel Group代码在openmdao 2.2中。手册不起作用。 对于每次尝试(不同的计算机),我似乎得到另一个错误,其中大多数似乎是兼容性错误(即我安装petsc4py,打破numpy或mpi4py安装导致现有的openmdao核心问题。)

在某些计算机上,我安装了自己的openmpi和petsc,但就我看来,conda install命令已经安装了那些。

最终我在新启动的亚马逊实例上尝试了这些步骤 但有类似的问题。

sudo apt-get install build-essential 
wget http://repo.continuum.io/archive/Anaconda3-5.2.0-Linux-x86_64.sh    
bash Anacond*
sudo apt-get install libibnetdisc-dev
sudo apt-get install libblas-dev libatlas-dev liblapack-dev
conda install mpi4py
conda install -c conda-forge petsc4py 

如果我查看'' conda list''缩写输出的计算机;

如果尝试运行,则在同一系统上 mpirun -n 2 python my_par_model.py 基于手动代码,这就是我得到的

aws snapshot

有没有人有一个建议可能会失败,或者我可以遵循哪些步骤来实施anconda / openmdao / petsc / mpi4py和成功运行paralel openmdao?

您可以查看我们的.travis.yml文件中存在的linux安装实现吗? https://github.com/OpenMDAO/OpenMDAO/blob/master/.travis.yml

这适用于在Travis CI上的Trusty Tahr实例上从头开始安装和测试OpenMDAO。我乍一看的一个区别就是我们使用pip将mpi和PETSc安装到conda安装的python中。

答案 1 :(得分:1)

我认为MPI兼容性是主要问题。我不知道它必须是openmpi并且确实conda install命令安装了mpich并且可能导致openmdao出现问题。

我会继续做更多的测试,但对于从全新安装的ubuntu-16.04.4-desktop-amd64.iso开始的工作系统,我按照这些步骤操作;

(花费时间的步骤是openmpi安装和petsc4py pip instalattion。)

1)对于某些依赖项(取自https://gist.github.com/mrosemeier/088115b2e34f319b913a

sudo apt-get install libibnetdisc-dev
sudo apt-get install libblas-dev libatlas-dev liblapack-dev

2)下载/安装OpenMPI(主要取自http://lsi.ugr.es/jmantas/pdp/ayuda/datos/instalaciones/Install_OpenMPI_en.pdf

wget https://download.open-mpi.org/release/open-mpi/v3.1/openmpi-3.1.0.tar.gz 
tar -xzf openmpi-3.1.0.tar.gz 
cd openmpi-*
./configure --prefix="/home/$USER/.openmpi"
make
sudo make install
echo export PATH="$PATH:/home/$USER/.openmpi/bin" >> /home/$USER/.bashrc
echo export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/.openmpi/lib/" >> /home/$USER/.bashrc

3)MINICONDA&amp;休息(主要取自https://github.com/OpenMDAO/OpenMDAO/blob/master/.travis.yml

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
sh Minicond* # agree to add to the path etc.
conda install --yes python=3.6
conda install --yes numpy==1.14 scipy=0.19.1 nose sphinx mock swig pip;
pip install --upgrade pip;
pip install mpi4py
pip install petsc4py==3.9.1
#petsc4py Gives an error failed building wheel for petsc but then installs petsc itself, afterwards, petsc4py is also installed

sudo apt install git  # in the cases git does not exist

# not sure why we need this part but i followed 
pip install redbaron;
pip install git+https://github.com/OpenMDAO/testflo.git;
pip install coverage;
pip install git+https://github.com/swryan/coveralls-python@work;
# pyoptsparse and openmdao
git clone https://github.com/mdolab/pyoptsparse.git;
cd pyoptsparse;
python setup.py install;
cd ..;
conda install --yes matplotlib;

git clone http://github.com/OpenMDAO/OpenMDAO
cd OpenMDAO
pip install .

# optional  
conda install spyder 

4)检查版本

mpirun --version : Open MPI 3.1.0
python --version : 3.6.5
pip --version   :  
pip 10.0.1 from /home/user/miniconda3/lib/python3.6/site-packages/pip (python 3.6)



conda list : (note that there is no mpich or similar in the conda list)
