but mining GPUs could make petaFLOPS. From what I heard AMD says one 32bit INTOP is two 16bit FLOPS (see #70 above). I think Guinness will accept it if we can convince them that at least 75% of the bitcoin network consists of GPUs. Unfortunately there is no way to prove this, is there?

Unfortunately no - for all we know, 90% of the hashing power could come from Chuck Norris with his abacus...

Of course you can argue indirectly: AMD GPUs are vastly superior in terms of Mhash/$ _and_ Mhash/W than anything else so that everybody not using it is most likely losing money on electricity (Nvidia/CPU) or on initial investments (ASIC/FPGA).
I'd cite the mining hardware comparison on the wiki as reference.

We make exactly 0 petaFLOPS

Ok, we have to work around it but how? You can't convert integer in flops operations...

I'm pretty sure the Guinness people aren't interested in what we could do, but only in what we actually do do. The right approach would probably be to ask them to consider adding a category that we do fit into.

They measure in FLOPS because that is what supercomputers do, and that is how supercomputers are measured.

If you want to walk on water, get out of the boat

It's like the world record on sport and saying "sport record must be measured in goal made" (refering to soccer i mean). And then we have runners arguing that the first place is like 3 goal in a soccer match and so on.

Seriously, "It must be measured in petaFLOPS and floating point operations per second." is idiocy.

That's what happens when people who know NOTHING about computing make the rules...

we just have to work arround it... and use it to our advantage Grin

Bitcoin is by far the fastest distributed computing network in the world. In this post we have started to claim that record at Guinness: https://bitcointalksearch.org/topic/bitcoin-guinness-world-records-29722

For the entry it is necessary for an expert to attest to the network speed. Still, I think it might speed things up if we would discuss the proper way for such an estimate here before.

Got news from Guinnes world records:

MOST POWERFUL DISTRIBUTED COMPUTING NETWORK
DEFINITION OF RECORD
This is for the most powerful distributed computing network.
It must be measured in petaFLOPS and floating point operations per second.

GUIDELINES FOR ‘MOST POWERFUL DISTRIBUTED COMPUTING NETWORK’
1. For the purposes of this record, a distributed computing network consist of
clients and servers connected in such a way that any system can potentially
communicate with any other system.

2. The capacity of the distributed computing network must be tested using
appropriate means.

3. The exact measurements of the distributed computing network must be given in
petaFLOPS and floating point operations per second.

[...]

I am aware we are not actually doing any FLOPS so we have to figure something out here to still make it work.

people have already thought about this a while ago: https://bitcointalksearch.org/topic/mining-power-of-bitcoin-vs-other-networks-4689 but we need to bring it all into order and make it possible to verify/validate everything.

What about this attempt:
(please correct me, my knowledge of the bitcoin network guts is still quite limited)

Assumption: SHA256 is fine

10) The network finds the solution to a specific SHA256 Problem (depending on difficulty)
The solution pops up in the blockchain
20) It takes n hashes to solve such a problem on average
SHA256 picture book???
30) Problems (blocks) are solved at speed s
Blocks pop up at speed s
40) --> over a certain period of time t the network has to try m hashes
50) It takes i integer operations for a single hash
Kernel Analyzer?
60) --> over t there have to be i integer operations done in the network
70) For some strange reasons (muladd???) we can say that one 32bit INTOP is two 16bit FLOPS
??
