Unfortunately there is no order by a sequence number or so for PE, it will just try both and pick one of them.

OK, we'll do that. Maybe one could even use $pe_slots? This would not work for, say, 12-core jobs; but it should prevent 8-core jobs from using the mpi4 PE, thus spreading over two nodes.

Thanks for your reply!
