To clarify some confusion regarding CIQ’s recommendations for MPI: we recommend installing MPI in the Apptainer container, not using the “hybrid” method. Using PMI or PMIx support in your resource manager, you can start such MPI-equipped containers directly, without needing MPI to even be installed on the host system, which makes the container portable to any PMI-supporting environment, and carries no performance degradation. We have discussed this in previous webinars; in particular A New Approach to MPI in Apptainer and Apptainer MPI Benchmarking. ruclips.net/video/7cw_uVr5Ibk/видео.html ruclips.net/video/oMEQGEUauwQ/видео.html
