A repository for OpenMPI builds
Use either RPM or Docker to deploy
sudo yum install docker
sudo systemctl start docker
Install HPCCM by following the instructions on the HPCCM GitHub repository: https://github.com/NVIDIA/hpc-container-maker
Navigate to the 'Container' folder in this repository
sudo docker build -t openmpi .
Once the installation process is done, run:
sudo docker run -it --rm --net=host openmpi
Inside the container environment, you can compile the sample program with:
mpicc -o mpi_hello_world mpi_hello_world.c
And then run with:
mpirun -n 4 --allow-run-as-root ./mpi_hello_world
Steps taken:
Install necessary software:
sudo yum install rpm-build rpmdevtools
Build directory structure:
rpmdev-setuptree
Create a new Spec file:
cd ~/rpmbuild/SPECS rpmdev-newspec openmpi.spec
Build the RPM with:
rpmbuild -ba ~/rpmbuild/SPECS/openmpi.spec
To add this repository to your operating system, you need to create a new file called openmpi.repo in the /etc/yum.repos.d/ directory with the following contents:
[openmpi]
name=OpenMPI
baseurl=https://raw.githubusercontent.com/phanchieta/OpenMPI/tree/main/RPM/rpmbuild/RPMS/
