We make several MPI implementations available to our users (http://docs.hpc.shef.ac.uk/en/latest/sharc/software/parallel/) so I was hoping to find a mechanism where an env var automatically could be set (to a per-host value) for any slave task, regardless of what is being run in the parallel environment.
