Support single-rank MPI tasks in Raptor and RP proper #2871

Open andre-merzky opened 1 year ago

andre-merzky commented 1 year ago

By default, single rank tasks are non-MPI tasks, but ScaleMS uses the MPI communicator to inspect available resources, and that's usefule for single-rank tasks also.

Can you comment on the relationship between this issue and #2896?

2896 resolves the problem for RP executable tasks (although it is less prominent there) - this ticket will build upon #2896 to resolve the same for Raptor tasks.
