As an additional improvement, is it really needed to count every machine? We can subsample a lot, and only let some specific machines to show up for counting. That is, apply the logic above only if(hash(machine_id)%1000==0) (this becomes a poll instead of a referendum, results must then be multiplied by 1000) Or, to avoid having somebody constantly be counted and other constantly ignored, the rule could be if(hash(machine_id)%1000==hash(weekofthecentury)%1000) With this setup I know that 99.9% of the weeks I'm not reporting anything at all. Of course 1000 is a constant that may be tuned, but looks a good choice to me if the expected total number is on the order of 1 million.
