Task #2425
testing multisim with multiple ranks per simulation
Description
As #2403 shows, we have a gap in testing coverage (and IIRC there were past issues when refactoring multisim and multiple ranks per simulation)

The gap is actually somewhat, I'd suggest broadening this to covering better all domain/multi-rank decomposition modes (1/2/3 dim DD +/- separate PME with/without multisim).

- Target version changed from 2019 to 2020
We need better infrastructure and design in order to be able to cover both one-rank per sim and multiple-ranks per sim, and definitely more work for the cases Szilard suggests (and anyway we will not be able to fully cover a whole multi-dimensional array of test cases).
