I don't remember the exact use case but it was basically a machine where the topology strange or broken and the user wanted to force the distribution among some given object type (the distribution of objects of other types was unusable). > Same here, distributing 4 elements between the PUs, thus selecting the > first 4 PUs. > > I'd say that --among should indeed be the horizontal portion of the > machine to distribute on, and the existing --among option should be > renamed into --from, and a --to option could be added to stop the > hierarchical distribution to a given object type. > Works for me but won't have time to look at it before the end of the week. I don't think --among was available in 1.0, so maybe we can rename it in 1.1 and we'll add other options in 1.2 ? Brice
