Tesla cards are good for double point precision calculations which is good for science simulations where accuracy is paramount. Bitcoin mining relies on raw mathing power where accuracy isn't as important as speed. Yes, I just said mathing.

I am new to bitcoin, but such as I know, the flops and hashes are totally different.
flops are float computing unit while hashes are integer computing unit
flops are float computing unit while hashes are integer computing unit
Correct. And there is no correct way to make a meaningful conversion equation between FLOPS and MIPS.
Will. didnt he say flops and hashes?
Doesn't flops indicate how quickly math can be done.. and a hash is a cryptographic function using math?
Or do hashes better coorelate to MIPS..
Someone should e-mail cray and ask how many SHA256 operations it can perform per second, lol.
Different kinds of math, floating point versus integer. There's no direct correlation between ability to perform one or the other.
I'm curious..
Why would bitcoinwatch use TeraFLOPS as an alternate unit of measure to indicate the network hashrate of the bitcoin network if it doesn't even correlate correctly?
Network Hashrate TeraFLOP/s 48249
Kinda silly to do such a thing... if the math doesn't even work.

Science = FLOPS
Hashing = MIPS
Hashing = MIPS

And if you don't think the US Gov't can't afford 2 of these and then fire em up and pwn the network at will...

I'll take 2 please

"Sure, IBM's ten petaflop supercomputer may sound impressive, but Cray can do you five better -- the outfit just announced the Cray XK6, an upgradable, hybrid supercomputing system capable of more than 50 petaflops of computational muscle. Powered by Cray's Gemini interconnect, AMD Opteron 6200 processors, and NVIDIA Tesla 20-Series GPUs, the XK6 system blends x86 and GPU environments with the firm's own flavor of Linux. The folks at Cray won't resort to bragging, however -- they're humbly declaring the machine to be the first "general-purpose supercomputer based on GPU technology," and not, as they put it, a stunt to place high on any Top 500 lists."
http://www.engadget.com/2011/05/25/cray-xk6-supercomputer-smashes-petaflop-record-humbly-calls-its/
So... exactly how many Gigahashes does 50+ petaflops equate to anyway?

A bit more than the current hashrate of Bitcoin combined (~48 Petaflops according to http://bitcoinwatch.com/)
