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

[Ryland R. Taylor-Almanza]

awesome, thanks for pointing that out!

Edit: Did you mean "vanitygen --help"? I can't find anything about SolidCoin addresses.

[jackjack]

Code:

-X <version>  Generate address with the given version

Find the version of solidcoin addresses and use this flag

[Ryland R. Taylor-Almanza]

What's the version of SolidCoin addresses?

Nice avatar, by the way. May you be touched by his noodley appendage.

[joulesbeef]

version seems to be 125 but I know you knew that.. this for those who come after you.


anyways can we get the error message about bitcoin addies needed to start with 1 when using -x version?

it doesnt like when i do -r 125 scow and yet if I just do -r 125 cow it comes up with n scowdkjgfksdhg addy

it also doesnt seem to like the lowercase i when i use version, which is totally blowing my vanity addy of sir1oin and even ir1oin doesnt work

Same problems here.

I've tried building oclvanitygen on my headless Ubuntu miner without success.

It always stops due to not finding the library "OpenCL". It compiles ok (because I manually added the SDK include path) but can't link.

I have the AMD SDK 2.4 installed (can mine without issues) but as far as I can see the SDK lib/x86 directory only contains shared .so files. There are no .a static libs for linking present.

Does anyone here know more about this?
Are the static libs put somewhere else or need to be built separately?  

EDIT: Here's a patch for what I did to get oclvanitygen to build.
Just changes to Makefile so correct include and lib dirs are used.
Assumes 32 bit as otherwise the lib dir is x86_64

Code:

--- Makefile.org	2011-09-14 13:01:06.000000000 +0700

If you save this code into file p1 in src dir, cp Makefile Makefile.org,
then you can apply the patch with, patch <p1

I get about 21 MH/s when using oclvanitygen with 1x 5830.

This is awesome. I ran it on my linuxcoin mining rig after "sudo apt-get install libpcre3-dev" no problem.

Code:

[user@miner vanitygen]$ patterns=( vanity1 vanity2 vanity3 ... vanityN )
[user@miner vanitygen]$ for pattern in "${patterns[@]}"; do ./vanitygen 1${pattern}; done

Rather than running it separately for each pattern, if you use the option to create a file with the patterns you're looking for, it can check each address it generates against all of them at once, which should be faster.

Oh I didn't even notice that.  Looks like you can pipe from stdin too.

Code:

./vanitygen --help

How i should specify a platform for OpenCL?
-p 0 not works for me.

Upd. Solved. Have to specify platform first, pattern next.

Unfortunately it doesn't work for me (Ubuntu, sdk 2.1, ati 5970):

I tried many parameters like -V -S etc, but without success :-(.

Interesting. New version of AMD video drivers came out, and now ocl is working fine Guess it was them, not you. Thanks!

[wobber]

Great app. But what do I do with the generated data? How do I get to use it?

It's in the first post ("How do I get the generated private key into bitcoin?"). Follow that, and it will put the address in your wallet and its addresslist, so you can use it. Make sure to back up your wallet beforehand.

Although nowadays you can have mtgox "eat" your private key, and then all funds on it will periodically be deposited into your account.

Is it necessary to let vanitygen run continuously in order to find the desired key, or can I stop it then start it again?
Ie. does it use the same starting point every time, so that when I start it for a second time, it goes through the keys that it has already gone through the first time?
Asked a third way, to make sure I'm making myself clear, if there's a 50% chance a key will be found in 24 hours of continuous operation, is there also a 50% chance a key will be found if I run the application for one hour on 24 separate days?

[slush]

runeks: It's generating random keys, so yes - you can stop it anytime and it don't lower your chance to find proper address...

[runeks]

Cool. Good to know. Thanks!

[BTCurious]

Unless you put in a custom seed, but you probably don't do that, anyway

ATI 11.10 WHQL - Now works! It appears that the newest SDK is the fix, as by extracting the ATI "driver only" downloads, you can install just the video driver you want, and then install the newest 2.5 SDK from C:\ATI\Support\11-10_vista32_win7_32_dd\Packages\Apps\OpenCL. I have tested this SDK with the 11.6 and the 11.10 video driver.

Memory speed seems important to keygen speed too. If you've downclocked memory for mining, be sure to bump memory speed back up to default or even overclock.

Benchmarks:
CPU: 113 Kkey/s per core on 2.4GHz Intel Core2 Quad (32 bit)
CPU: 131 Kkey/s per core on 2.7GHz AMD Sempron 140 / Athlon 64 X2 Kuma
GPU: 15.3 Mkey/s on ATI Radeon HD 5770 (1000/1300)
GPU: 20.5 Mkey/s on ATI Radeon HD 5830 (1050/1050) (5 char address in ~13 seconds)

EDIT: DON'T try to upgrade Linuxcoin with "apt-get upgrade". If it goes the way it did for me, it will break horribly. The errors just didn't appear until I restarted. Now fglrx (and thus OpenCL) doesn't work.

Yay! I finally got this working in Linuxcoin. I had to increase the Linuxcoin persistence file system (live-rw file) to 3GB in order to be able to upgrade via "apt-get upgrade", and had to change the following line in Makefile:

changing the second line from:

Code:

oclvanitygen: oclvanitygen.o pattern.o util.o
	$(CC) $^ -o $@ $(CFLAGS) $(LIBS) -lOpenCL

to:

Code:

oclvanitygen: oclvanitygen.o pattern.o util.o
	$(CC) $^ -o $@ $(CFLAGS) $(LIBS) -L/opt/AMD-APP-SDK-v2.4-lnx64/lib/x86_64/ -lOpenCL

Oh, and I had to install libssl-dev, libpcre3, libpcre3-dev (as others have mentioned).

Getting a steady 31 Mkey/s on my 5870:

Code:

user@linuxcoin:~/Desktop/vanitygen$ ./oclvanitygen -d 0 "1runeks"
Difficulty: 888446610538
[31.13 Mkey/s][total 355205120][Prob 0.0%][50% in 5.5h]

I haven't tried tweaking any parameters except adding -w128 and -w256 which seemed to produce the same results.

Thank you for making this!
