Well? OSTP’s Associate Director for National Security and International Affairs Dr. Patricia Falcone provided keynote remarks yesterday at a ribbon-cutting ceremony celebrating the opening of the US Army Research Laboratory’s (ARL) new supercomputing center at Aberdeen Proving Ground in northern Maryland...
The new ARL Supercomputing Center—containing two new IBM iDataPlex computers with the capacity to perform 50,000 trillion floating point operations per second, or 50 petaflops—will provide state-of-the art high performance computing capabilities as well as extraordinary capacities in advanced high-speed networking and data analysis, providing unprecedented benefits to the Army, the Department of Defense, and the Nation as a whole.

Buy a TREZOR! Premier BTC hardware wallet. If you're reading this, you should probably buy one if you don't already have one. You'll thank me later.

If the US government wants to attack to bitcoin has lot ways to do it efficiently.

Petaflops are totally useless for mining ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) I wouldn't say totally... How many floating operations are required for sha hashing?

EDIT: I googled and found that u need only 3 floating-point operations for SHA-256 hashing - https://blogs.oracle.com/DanX/entry/sparc_t4_digest_and_crypto.

I think winning wars comes above that. Example the game theory of mathematicians like John Nash during the cold war.

If petaflops were the only thing determining hashing speed - which I don't think it is because SHA relies more on integer operations than floating point ones - looking at this http://en.wikipedia.org/wiki/Radeon_HD_7000_Seriesthere is a column called GFLOPS - i guess gigaflops and the 7950 has 2867 gigaflops or .002867 petaflops. so 50 petaflops = 17440 AMD 7950s = 17440 x 600 MH/s = 10.5 TerraHashes per second

I would be more worried about them. Tesla K20X Peak single precision floating point performance 3.95 Tflops (50 petaFLOPS)/(3.950 teraFLOPS) = 12,600 @ $13,000 = $163million Assume BGQ rack is $2-3 M range and performance of 50 GFlops/node http://www.usqcd.org/meetings/allHands2012/slides/Mawhinney.pdfSo the CUDA version is quite a bit more expensive, but probably works 163x better.

Petaflops are totally useless for mining ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) It might be better at scrypt mining. It could even possibly do a 51% attack on all of the scrypt coin chains.

This is a data center for the NSA, they focus on encrypting and decrypting data... I bet you those data centers are full of Purpose built ASIC SHA2-3 AES etc encryption chips.

If you think my efforts are worth something; I'll keep on keeping on. I don't believe in IQ, only in Determination.

The IBM technology is software based, not hardware based. It decentralizes the computations at a software program level so that you can run the program spread out over many machines. This works really well for feeding data through it in real time and not having any bottle necks. I used to work for IBM and took a class on how to use their Watson technology.
As for mining, saying that this is something to worry about would be like saying that we should worry about them using 100-1000 computers using CPUs to do a 51% attack.
But when I took the class they mentioned that they were able to feed all of the data of the Internet through the thing in 2 weeks. They tried to see how much data could break it in a simulation and their data producing engines could not create data fast enough to overwhelm it.

Should Bitcoin fear the Army's new computer?
