mfisherman/openmpi repository overview

⁠openmpi

The Docker image openmpi relies on Alpine 3.21.3 and contains Open MPI 5.0.8 (latest). It allows you to build and run your MPI programs in a docker container without the need to install MPICH or Open MPI on your machine.

See the GitHub repository ⁠ for more information.

⁠Tools

The following tools are installed:

• Open MPI compiler (mpicc and mpicxx) and mpirun
• gcc and g++
• Common developer tools (make, wget, curl, etc.)

⁠How to use

Run the following command:

$ docker run --rm -it -v $(pwd):/project mfisherman/openmpi

It will automatically download the docker image to your system and run it. The argument -it allows you to run the container in interactive mode and will open a shell. Further, the command mounts the directory, from where you run the command above, into the folder /projectof the container. That way you can use your favorite editor to write your code an run mpiccand mpiccxxin the container.

⁠OS/ARCH

The image is built for a majority of Linux architectures, allowing you to run the image even on all Rasperry Pi versions (e.g. as gitlab-runner). The available operating systems and architectures are:

• linux/amd64
• linux/arm64
