Right, well, vanitygen was made and supplied to you for free. Why do you think its unacceptable when you didn't even pay anything for it?

Are you saying that AMD cards and drivers should be made to run vanitygen? What a joke. AMD cards are designed to appeal to and function for gamers, not people with an interest in cryptocoin software, we are an extreme minority to them, barely worthy of their acknowledgement.

while i agree with you i still wonder why after such a long time where newer drivers have come out and people have been complaining about this problem here there seems to be nobody capable of fixing it. the original author might have gone AWOL 11 months ago but the source is available so there should be an enthusiast able to fix it. even if it's really a bug in the AMD driver it should be possible to create a workaround. have there been attempts? why did they fail?

unfortunately for me with an HD7970 GHz edition on catalyst 13.4 not even the slower -S option helps. if i use it oclvanitygen.exe crashes during "Compiling kernel, can take minutes...". looking at the amount of people who haven't got it working even after a driver downgrade i don't think i will even bother to try that. anyway, my CPU (Core i7-3770k) is doing 1.44 MKey/s and that's enough for my small needs (guess i am not THAT vain after all  Grin). i am just curious how things can get stuck in such a way in an open source environment.

Because vanity gen addresses are a minor niche of cryptocoins and people would rather use their hardware to mine and make profit.

I installed video driver Catalyst 13.8 beta and it seems to still be working with oclvanitygen on my HD5xxx, going from 11.11.

many posts so far have indicated that the problems are related to the actual hardware rather than to the driver, your post makes it +1  Wink

Anyone able to explain how someone was able to mine this address: 1111111111111111111114oLvT2

Seems to be crazy hard, that's 21 1's in a row!  Shocked

That's not a "real" address.

Just like 1BitcoinEaterAddressDontSendf59kuE.

Nobody has the private keys for those two.

It's important to note that searching for short addresses (<34 standard character address length) by utilising "1"*n patterns has a greater difficulty than other patterns of the same length.

I have found several hundred 31 length addresses and a few (2 or 3) 30 character addresses running my 7950 at work over a many-month long period of time.

Yeah, I hadn't factored in the extra difficulty from the fact it's all 1's / is such a short address, I was just messing around on FirstBits and was shocked to see that address in use!

Is there a way to easily calculate the difficulty (without mining for it) through a web-app or what not?

oclvanitygen gives me an error while trying to use it:
"Error loading kernel file 'calc_addrs.cl': No such file or directory"
On a windows machine.

To be clear: both files, oclvanitygen and calc_addrs.cl are in the same folder

Edit: Run in administrator mode, error log

Compiling kernel, can take minutes...failure.
clBuildProgram: CL_BUILD_PROGRAM_FAILURE
Build log:
Error: Code selection failed to select: 04B3A1A0: i32 = bswap 04B3EC00

Is there? Or maybe data from experience for 5-7 char length?

Well, it's obviously calculable (probalistically), so there's no need to do it from data.

The code to make this calculation has already been written and is included in VanityGen, so if you really want you could always pull that bit of the code out and make the app yourself...  Wink

Lol, I don't know how "real quick" it would be, I've never looked at the code. You can always just run vanitygen with the expression as it runs that part of the code automatically and outputs the estimate. Can you just use this?

I just ran it. Obviously didn't finish the longer ones. My laptop is also slow as you can see, 100 Kkey/s.

Up to 1234 is almost instant. Longer prefixes take longer amounts of time. People who managed to get this working on their GPUs have faster times or less times needed to generate.

In case anyone works on this program again (it would be nice if it worked on modern cards again), I have a suggestion. Have it so you can put in a big list of strings and let it match on any of them. When I use oclvanityminer it appears to only grab 1 string from the list and just dial up addresses until it finds a match. But wouldn't it be better to just search for a lot of addresses at once? Or maybe that is not possible to do on a GPU?
I look at a page like this: https://vanitypool.appspot.com/availableWork and think, why can't I just wardial addresses and look for them all at the same time?

If you are using vanitypool, each address request has an associated secret.  The people working don't have access to the secret, but it is a factor in the resulting address, so you can only look for one at a time.
