```
sudo apt-get -y update 
sudo apt-get -y install build-essential flex zlib1g-dev libgmp-dev libmpfr-dev
wget https://download.open-mpi.org/release/open-mpi/v4.1/openmpi-4.1.6.tar.gz 
tar zxf openmpi-4.1.6.tar.gz 
rm openmpi-4.1.6.tar.gz 
cd openmpi-4.1.6 
./configure --prefix=/opt/openmpi-4.1.6 
make -j 4 all 
sudo make install 
echo 'export PATH=$PATH:/opt/openmpi-4.1.6/bin' | sudo tee -a /etc/bash.bashrc
```
