~20Pflops = 3 terahashes/sec, which will earn you about $274/hour. Probably not the best use of supercomputer resources. :)

How did you calculate that? Those units don't quite work out. It's a totally different architecture to your standard i7/radeon home mining rig.

I don't think it's actually that different, through not as easy to calculate as e did.

Quote, Wikipedia: "Titan has 18,688 nodes (4 nodes per blade, 24 blades per cabinet), each containing a 16-core AMD Opteron 6274 CPU with 32 GB of DDR3 ECC memory and an Nvidia Tesla K20X GPU with 6 GB GDDR5 ECC memory."

So it's pretty much standard hardware just a lot of it. Except that the graphics card is basically a consumer tesla with some extra juice, but it's still just a card built with what's possible today. Nothing extra fancy.
