The only difference is For development is very useful to use interactive shell inside the Singularity container. In this interactive shell you can make any changes to the image you want, but be aware that you can not use the `sudo` privileged commands directly on the cluster. To invoke interactive shell easily just use the `image-shell` command. -Another useful feature of the Singularity is direct support of OpenMPI. For proper MPI function, you have to install the same version of OpenMPI inside the image as you use on cluster. OpenMPI/2.1.1 is installed in prepared images. The MPI must be started outside the container. The easiest way to start the MPI is to use the `image-mpi` command. +Another useful feature of the Singularity is direct support of OpenMPI. For proper MPI function, you have to install the same version of OpenMPI inside the image as you use on cluster. OpenMPI/3.1.4 is installed in prepared images. The MPI must be started outside the container. The easiest way to start the MPI is to use the `image-mpi` command. This command has the same parameters as the `mpirun`. Thanks to that, there is no difference between running normal MPI application and MPI application in Singularity container. ## Examples -- GitLab
