Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[dishwara]

For those who cant able to still run oclvanitygen, getting found delta, start delta.....
Just use driver uninstaller, i used this DDU from http://www.guru3d.com/files_details/display_driver_uninstaller_download.html.
unzip it in a folder in desktop, restart system in safe mode, run Display Driver Uninstaller.exe, select AMD-> Clean and restart.
It will remove all amd drivers & restart system.
Now just install 12.10 driver & everything works fine.

Do you have a precompiled OSX build of Vanitygen?

Looking for a precompiled OSX build as well

get home-brew, then use

Code:

brew install vanitygen

Can I use vanitygen to find someone else's private key from their bitcoin address?

Can an example?
either here or in PM.

In theory: No. The software will not allow you to specific a pattern so specific/long. Yes, I tried it: for lulz. Why don't you download the program, tell it to look for a pattern eg. 10 characters long. Then make it 11, then 12... and so on while observing the time estimate to find a match... you will see what I mean quite quickly. Now, keep in mind that bitcoin addresses are usually 33-34 characters long.

In practice: Also no. It would take an impossibly long time. We're talking longer than the time the universe will likely exist for. If you know a loophole around that, please let us know. We should also stipulate a rule that to mention "quantum computers" you must at least have a masters/PhD in a relevant field.

brew install vanitygen

I did that but got an error message:

Error: No available formula for vanitygen
Searching taps...

Then I saw a post by user Red Emerald that recommended:

brew tap WyseNynja/bitcoin && brew install WyseNynja/bitcoin/vanitygen

That worked well on my MacBook Air with OS X 10.9.1 !

I can't install homebrew; administrator controls.  Vanitygen on windows works fine because it's a plug and play app

[miaviator]

Ubuntu:

Code:

 git clone https://github.com/samr7/vanitygen.git
cd vanitygen
sudo apt-get -y install libpcre++-dev
 make vanitygen oclvanitygen oclvanityminer CFLAGS="-I/opt/AMDAPP/include/"

-I is wherever AMDAPP is installed on the system.

The loophole around large number obscurity is luck.

Also having the GPU hash/CPU hash error. I'm running Catalyst 13.11 and downgrading is not an option for me. Also AMD APP SDK v2.9, willing to downgrade this if this is the issue.

Having this error as well, and also downgrading is not an option.

Anyone have any solution for this?

Yes, the solution is to rewrite vanitygen in opencl 1.2. Of course, why should this happen, the last time someone donated to samr, it was 0.001 four months ago, and then $2 worth a year ago.

"downgrading is not an option"...heh

Why do you say that the real solution is to rewrite for opencl 1.2?

[deepceleron]

Because the software has not been largely updated since it was written, which is when opencl 1.0 was just transitioning to 1.1.

OpenCL apps have not yet become generic, they almost have to target a particular card and driver, since driver updates keep breaking things.

Here is an interesting topic - below are the only ATI HDXXXX GPUs that support double-precision math. It would be interesting to see if the computing problem on new drivers varies based on this card list:

HD 5830 HD 5850 HD 5870 HD 5970

HD 6930 HD 6950 HD 6970 HD 6990

HD 7730 HD 7750 HD 7770 HD 7790 HD 7850
HD 7870 HD 7950 HD 7970 HD 7990

I have a 5770, and vanitygen works fine (and first worked correctly) using Driver 11.11, which includes the SDK 2.5 runtime. It doesn't work on any later drivers. One conspiracy theory could be that other OpenCL computing features were disabled on single-precision cards in later drivers.

Here is a list of each first driver version that included a new SDK. You must also be aware that the ATI uninstaller does not properly uninstall key OpenCL files. If you want to experiment, you should increment starting with older versions, so you don't have to manually delete left-behind files each time.

AMD APP SDK v2.9    AMD Catalyst™ 13.11 beta (13.20.16)
AMD APP SDK v2.8.1    AMD Catalyst™ 13.6 Beta2 (13.101)
AMD APP SDK v2.8    AMD Catalyst™ 12.10 (9.002)
AMD APP SDK v2.7    AMD Catalyst™ 12.4 (8.961)
AMD APP SDK v2.6    AMD Catalyst™ 11.12 (8.92)
AMD APP SDK v2.5    AMD Catalyst™ 11.7 (8.872)
AMD APP SDK v2.4    ATI Catalyst™ 11.4 Update Driver (8.841)

Thanks for the information on GPU generation!  Is generation possible on r280/r290 cards with the latest drivers?

Wow, I'm ashamed. I use this tool all the time. I didn't even think about that. I would be one of those people leeching off of his fantastic work, and telling him he needs to update the tool.

Will be donating very soon.

Edit: deepceleron, what is his donation address. :s

[PBmining]

Is there a windows build for this?  All I see so far from reading through the thread is Linux.

When i try to start the miner it only say the "avalibe openCL devices" and exit. Why and how can I fix it?

Perhaps you might share what Operating System, what command you typed and any other details at all?

You need to install openCL drivers, video card drivers on win and AMDAPP on lin.
