Why does it require a BF for each process? Couldn't just the BF get loaded to VRAM and then each process references that one instance? I am not questioning your work, just digging for information for a better understanding.
I'm sure one BF per GPU could be enough and I probably could even figure out how to do it. I just want to avoid a multi-kernel setup for as long as possible, Inter-kernel communication seems quite ... challenged. I thought about a finer granularity of GPU kernels with a nifty producer/consumer pipeline, where the app would find out which kernel needed which ressources/time and then do an optimal setup for the given GPU device(s). Unfortunately, up to OpenCL 2.0 (which nVidia hardly supports) there is no way for kernels to communicate directly except pushing their results back to host and host pushing them again to the next kernel. This is like still having the Mach2 Concorde, but on a flight from New York to San Diego doing refueling in Chicago, Kansas CIty, Dallas and Phoenix.... OpenCL 2.0 (and later) has something called pipes, but we can't rely on that yet. Not without significantly reducing the number of devices LBC would run on. So as of now, I'm trying to have a single-kernel key generation stream. If it works, it's darn fast (therefore the GPU has hardly load). If it works... And shit, those are nice workstations at a pretty decent price, kind of pissed I bought an MSI GS70 Stealth Pro.... ~6 Mkeys
After posting this, I looked up the P51 which should be available April 2017. It has a Quadro M2200M which is about 40% faster than my M2000M. Intriguing... Rico

Is this project also based in Switzerland? Like the Large Hedron Collider? Wondering if private keys are found for a loaded BTC address what is going to happen to the funds? Is this just for research or actually trying to steal people's money? Imagine finding the private key for some of Satoshi's addresses...

Is this project also based in Switzerland? Like the Large Hedron Collider? Servers are all over Europe, clients are all over the world. Some are even in Switzerland - as the Large Hadron Collider. Wondering if private keys are found for a loaded BTC address what is going to happen to the funds? Is this just for research or actually trying to steal people's money?
See the thread. So far we announced and have a specific process defined. The main task is to search for collisions. If the clients get a regular finders fee before returning funds to their rightful owner, it's thier motivation. Blatantly stealing funds is frowned upon. Imagine finding the private key for some of Satoshi's addresses...
While Satoshi may own some million BTC, it's a common misconception these would be all on one address. More probably they are distributed among some thousands of early 50 BTC block rewards sitting on the blockchain. And ... boy would it be cool if he showed up to claim his funds! Rico

Proving one has the privkey to a 80k BTC address discards the need for any further proof down the line. The laws of physics don't apply anymore etc. https://www.youtube.com/watch?v=G_Cvtr86H5gAnd your notorious requirement of negative proof... almost looks like you beg for upgrading your title from mascot to jester.

Rico Speaking of physics, finding a collision is similar to quantum particles, only the observer really knows, lol. Perhaps Schrodinger's equation will become Becoin's equation or the probability wave that the private key belonged to the finder already or...not. Becoin is making quite the interference pattern on this thread, LOL. Thanks, Jude

Yes, but finding a privkey to an existing address with funds on it are proof of a collision. Where you are having trouble is whether or not the "proof" was intentionally placed there or not. Finding 1FeexV6 would probably be the best proof possible as there have been no outputs from that address at all... I would consider that address a "dead" address as the owner of the private key would most likely have moved those coins. Thanks, Jude

@rico666 "....Because we assume the private keys to addresses with funds on them are also uniformly distributed in the search space, this means that the effective search space until any collision for these is found is 160bit - log2(9000000)bit = ~137bit."
I might be wrong, but because of this (wolfram alpha expression):
1-(((2^21)! * (2^160 über 2^21))/((2^160)^(2^21)))
I assume the possibilty of hitting one of your approximately 2,5 mil target addresses is: 1.5*10^-36 or 1/(2^119)
~119 bit problem not a ~137 bit problem
I know that is still a massive challenge.
If you agree with the things written above, I would recommend to expand the target address space to 2^23 (8.x mil pub keys) and gain a 4 times higher possibility to hit one of your targets: 2.4*10^-35 or or 1/(2^115)
115 bit with the cost of analysing 8 instead of 2 mil pub keys.
Regards, Janu$$

Yes, but finding a privkey to an existing address with funds on it are proof of a collision. NO! It just proves you've "found" the privkey for that bitcoin address. To find a collision you have to find TWO privkeys to the same bitcoin address!
