ubuntu18.04LTSでopenMPI 4.0.0をcuda有効にしてパッケージ化してインストールする方法

More than 1 year has passed since last update.

ChainerMNにcuda有効化openMPIが必要だったので,openMPIの最新4.0.0をパッケージ化してUbuntuに入れる方法.

  • rpmbuildのオプションに--with-cudaを入れ込む
  • --enable-mpi1-compatibilityを入れないと実行時エラーが出た...
wget https://download.open-mpi.org/release/open-mpi/v4.0/openmpi-4.0.0-1.src.rpm
rpm -i openmpi-4.0.0-1.src.rpm
cd ~/rpmbuild/SPECS
rpmbuild -ba --define 'configure_options --with-cuda --enable-mpi1-compatibility' openmpi-4.0.0.spec

cd ~/rpmbuild/RPMS/x86_64/
fakeroot alien openmpi-4.0.0-1.x86_64.rpm
sudo dpkg -i openmpi_4.0.0-2_amd64.deb

あとはpip install mpi4pyすればchainer/example/chainermn/以下のサンプルコードが動く.
