Merge branch 'fsmpi' into 'master'

Minimal Viable FSMPI Deployment

Only commits with messages identifying fsmpi-specifics need to be refactored and removed after the upgrade. Other commits may introduce variables that are documented not to be relied upon in availability and functionality. However, we may decide to keep them (probably slightly repurposed) later on.
