well 1hash=~1300 operations a second (flops)
a quadrillion operations a second is less than 1 terrahash
..
not much these days.
though the numbers are guesses and estimates and not an exact science as you will see via the quote below
we are well past the days of CPU mining. and well passed the days of 'super computers'
ASIC's are way way way more efficient and cheaper than a PC/supercomputer
after all you can buy a 13terrahash miner for only a couple thousand dollars
According to bitcoinwatch.com
1 Hash = 12,697 FLOPs
Thats a gibberish number. It is like saying that one mile per hour is equal to 14.285 pounds (because some car that weighs 2000 lbs can go 140 MPH).
There are no floating point operations involved in the calculation of a bitcoin hash. None at all. 0 FLOPS.
Ngzhang says above that there are about 1300 32-bit operations (in one bitcoin hash) which sounds about right. So one 1GH/s would be equal to 1,300,000,000,000 operations per second.
If you're looking to, e.g. compare bitcoin's speed with various supercomputers you can just figure out how fast the supercomputer could mine. For example, one of the top machines is the Jaguar supercomputer which uses fairly standard opteron cores. I think my fairly boring rough numbers put it at about 522 GH/s. (pshaw, who says CPU mining is useless?
)
