Using eg. --inc:digits will hit poor territory with much lower node counts. But what I primarily wanted to air is I wonder if our current code will behave worse with very large number of nodes even if the *ranges* is not very small? For example: Does -node=1-30/100 or -node=1-300/1000 have more such issues than --node=1-3/10? I intend to have a look at that. If it does, we might want to tweak it: Splitting a job by eg. percentage can be convenient. magnum
