The article cites a BlueGene system with 768,000 cores. This article clarifies it as a BlueGene/Q system. Wiki said that each BlueGene/Q CPU is an 18-core PowerPC A2 @ 1.6GHz. That's puts Mira between 42 and 43 thousand physical CPUs.

We don't really know what those A2 CPUs can do for hashing, but we can estimate. The hardware wiki says that a Power7 from 2010 can get 7.6MH/s with 4 cores at 3.5GHz. Who knows if the A2 is faster than the Power7 (for hashing), but we'll go from those numbers.

So 7.6MH/s with 4 cores at 3.5GHz.
That's ~0.87MH/s per core at 1.6GHz.

Final number for all 768,000 cores: ~667GH/s.

That figure of power is easily dwarfed by the bitcoin network as whole

I doubt even 600GH/s could pay for the power it would need to run the entire system like this.

It took me a second to see through all of the universe making that it is, in fact, just a enormous cpu farm.
Impressive data crunch though.

at current difficulty that's about 210 bc a day times 30 days. it might pay for itself eventually. lol

I can almost guarantee you this costs more than ~2500USD/day to operate.
