Coolness. Thanks for the links! They estimate I'll top out at #17. That probably won't happen as one of my older laptops is about to be retired for the most part, but then again, it's not really contributing all that many cycles to the effort, so who knows? :-)
It will be really interesting to see what things look like in a month or two.
I believe that the computer junkyard (with a little help the last few days from one machine in a cluster of off the 'net, under the IT radar, ~25% utilized data crunchers - new software must be quickly checked against a few TB of real world data before being released for general use) has peaked.
It's been a good run, but is ~70x the normal home computer lab use and the folding farm that began to overtake the guest bedroom will have to be dismantled before it creates a fire or a divorce.
