I'll cheerfully admit I would not even have a clue how to find out what the problems might be that require $2m/day worh of computing, let alone how to submit such problems to the machine's mighty maw. I too would love to hear from anyone that does.

In the meantime this article linked at the bottom of one of Steve's link gives some food for thought (SFW unless you are at a religious institute or something I would think) about the problems faced in a 'sister' industry of our own. Redis sounds interesting.
