Then again, do remember the BTC network has GPU power equaling 146 petaFLOPS (146,407 gigaFLOPS) average as of July 2011. That's over a hundred times faster than the Tianhe-1 supercluster that held the #1 position on the top500.org list of the world's most powerful computers.
Well not exactly. Bitcoin does not actually do floating point calculations so the FLOPS value must be some kind of estimate. If your source is bitcoin watch then I cant find any confirmation of the number or even how it is calculated. So it is remarkable if true but needs to be taken with a grain of salt I think.
I am very interested in any type of confirmation or methodology for calculating the power of the bitcoin network in floating point, integer calculations or whatever.
