I have GF 9400m.

I use just "./vanitygen 1Name" without any bigger parameters (besides the oclvanitygen required -D). Did the same in Windows also.

I meant for oclvanitygen.  For instance I use "oclvanitygen -d0 1abcdef" to use my 6770 GPU.  I get around 12 Mkeys/sec this way.

What hardware/OS/drivers are you guys using?



I have :
Intel i7 3930K
Windows 7 x64 SP1
AMD 7970

I have tried 12.6 12.7 and 12.8 drivers.

Still have the problem.

Oh, sorry. I use the device parameter to point to GPU in Windows, in OSX 10.6 it either froze the system completely or gave up an error message. I've just installed 10.8 as my previous installation got completely messed up for some reason, so I've yet to try it under this one.

Yup, indeed it does - just ran it. Although I do get slightly better results (188KK/s vs. 170KK/s) with just CPU vs. GPU. But it's still bit under what I get in Windows, but that was in the 64 bit vanitykeygen - so I still want to know, how it's possible to run OSX version in 64bit mode?

It already does....  In fact I don't think Mt. Lion even comes with a 32bit kernel, but I could be wrong.

What GPU do you have?  I get ~4Mkey/sec with my GPU.

That's my impression also, but it's still quite a lot behind Windows 7 x64 in terms of performance - although major improvement over 10.6.

I have GeForce 9400m with 256 MB of VRAM, so not exactly a beast of a GPU  Wink

Ah ya, nvidia chips are not the best for mining.

You poor, poor Mac people.  If you want to play with the big boys you're gonna have to break out of the walled garden and get some real power tools.  Tongue

I compiled it on Windows, and I had the same problem.  Use the -o keyfile.txt option to write to file instead of standard out.

He's not the only one with the issue.
I think I had that same issue trying to gpu-mine with self-compiled code on linux.  I just gave up and use Windows.

I posted a thread here:

https://bitcointalk.org/index.php?topic=108451.0

Asking how to decrypt the protkey back to a privkey when using the -e flag and specifying a password.

Output like this:

Pattern: 1wtf
Address: 1WtFgLCoA56syuVLbvzCNzooTrKEpqyA8
Protkey: PsRUGbymw545hfYUAg5v8uNuVcxwtXWg646JkZ7nSm1dDRvHk5rTd8HrQv452ctz6fP2

and -e password used was 'wtf'

I tried several wallets, none of them recognized the protkey, is there a specific wallet or a command line tool for decrypting the protkey back to a privkey?

Is there anyway to force generation of the exact same sequence of addresses twice?
(I actually hope not.)

I tried playing with seed files but perhaps I misunderstood what those are for.

Seed files would be to seed the random number generator.  If you ran the same seed file at the exact same computer time on the exact same computer it could be possible to produce the same results or at least greatly reduce the entropy needed to find the results.  The seed file is any file that will change the outcome of the random selection.

There is a lot more involved with the internal random number generator but this is the short explanation.  Basically the seed file gives another source of randomized input.

Vanitygen is great, but I'm having an issue with the OCL version: it works, but if I abort it (by pressing Ctrl+C or terminating the process or any other way), my PC completely freezes and I have to turn it off & on.
The non-OCL version (either 32 or 64 bit) do not show this behavior.

I'm running Windows 7 x64 and a GTX560 with latest drivers.

In theory, there's no difference between theory and practice. In practice, there is.

Can't get the ocl version to work...

On nvidia:

Code:
vg_ocl_context_callback error: CL_MEM_OBJECT_ALLOCATION_FAILURE error executing CL_COMMAND_NDRANGE_KERNEL on GeForce GTX 285 (Device 0).

clWaitForEvents(NDRange,0): CL_MEM_OBJECT_ALLOCATION_FAILURE
Device: GeForce GTX 285
Vendor: NVIDIA Corporation (10de)
Driver: 285.62
Profile: FULL_PROFILE
Version: OpenCL 1.0 CUDA
Max compute units: 30
Max workgroup size: 512
Global memory: 1073741824
Max allocation: 268435456

on 7970:
(seems it is finding matches, but disregarding due to mismatch?
Code:
CPU hash: 6707a76e848f5e9368c2d9d9ec6d60880df44891
GPU hash: 020b0bda39a9bbb2eeddd194a8be20934835dff6
Found delta: 94027 Start delta: 1

Numbers look good though on the ati:
Code:
Difficulty: 873388193410
[27.27 Mkey/s][total 4630511616][Prob 0.5%][50% in 6.1h]


(for reference, on an i7 @4.2ghz, vanitygen64 does about 1Mkey/s case insensitive)

Amazing program.
Still playing with it, did a few which only took a few minutes.

Trying longer ones, but it seems to be be measured in many years by probability of success so I think it only find it if extremely lucky.
So I don't think I'll be seeing 1BattLeLords (First name of a game I'm developing) any time soon.
None the less very cool, my little laptop even happily manages 5 Mkeys/s which surprised me.

Yeah I got 1Lethos

Bitcoin addresses are Base 58 so every time you add a digit to the vanity part it multiplies the number of search permutations by 58.

I noticed Smiley I know I was just being over optimistic in thinking I could get a long one.

Where can I get keyconv for windows? I can't find it.

sorry, nevermind. Didn't see it in .21. Got it from .20.
