The computation took 23 days on 1,000 of Yahoo's computers, racking up the equivalent of more than 500 years of a single computer's efforts.

Let's see how my small 1 bit calulator performs: 23 days of 1000 computers is 23000 computer days, which is the equivalent of 23000/365 = 63 years. I don't need a computing cluster to see that this calculation is way off.
