Hey,

i will use oclvanitygen but I get an error, i  read 1 hours but i don't found the right solution.

i use Win7
AMD APP SDK\2.9 is installed

C:\Users\XX\Desktop\t
"calc_addrs.cl" is there

cmd, C:\Users\XX\Desktop\t\oclvanitygen.exe -d 0 -i Hello

error loading kernel file 'calc_addrs.cl': No such file or directory

so what I doing wrong

Very valuable addition, thank you very much! I'll look into it at the end of the week, when I have more time again.

What results did you observe speed-wise?

The relative speed differences as posted in the code blocks stayed more or less the same

so ~ +10 % from compressed to uncompressed (no change compared to original code)
    ~ +60 % from uncompressed to combined
    ~ +50 % from compressed to combined

I see no reason why these relative speed increases would not work in OpenCL.

As stated before, this was interesting to research.
Unfortunately I don't have a OpenCL environment, so I made the adaptations for CPU only

If you don't mind if the WIF key is compressed or not, there is a substantiation speed increase when
hashing both the Uncompressed and Compressed EC-point.
With my hack, I'm losing some time on the normal and compressed code execution due to selection overhead.
I'll update my repo @ github after some code cleaning :-)

I do not have time to read the whole thread.  Can someone give me an idea and/or link to the maximum key generation rate claimed?  It is for another thread...
But.. you no longer support vanity addresses... Wink

I haven' gone through the entire thread, I'd imagine there's some crazy SLI setup or so that'll go faster, but I did add the most recent reports to the wiki: https://en.bitcoin.it/wiki/Vanitygen#Expected_keysearch_rate

That page may also contain a hint for said other thread.

Does it?  Specs-wise, it is a good bit faster than the HD5870.  I can't say I know which specs' changes would best align with vanitygen changes, but it doesn't seem unfathomable.  I'm sure it's not even removely the fastest; but hardware review sites don't generally test against oclvanitygen Wink
I bought the 5870 when the R9s first came out, and it got swept by the HD5870s by about a 50% difference, as it did against the entire HD7xxx series.

 I can get 28MKeys/s with my Sapphire HD7970 and I recently acquired an ASUS Strix GTX 970 which gets 40+MKeys/s with much less power consumption.  

edit: This post is used as reference for the Vanitygen Bitcoin Wiki page so I thought I would add a screen cap which shows the performance of my Asus Strix GTX 970

Could anybody post the necessary code changes to allow oclvanitygen to generate compressed and uncompressed keys simultaneously? I suspect the speed increase must be substantial

Thanks!
Your "suspicion" is misplaced. The only calculation in common that would be saved is the calculation of the x coordinate of the public key, which is just a few multiplications. Everything else, from creating the compressed public key parity, creating an address from a compressed public key and checking for the vanity match would be a completely different process.
As stated before, this was interesting to research.

Has the HD5870 been superseded yet as the best vanity miner? I bought mine for $100 and it gets a whopping 30Mkey/s out of the box. Have newer gen GFX cards surpassed this?

No matter what I try, I couldnt make it work with OpenCL on my computer.

Did you update your video drivers?  (Hint: Version 12.10 works best - saves Delta from stalking you in the middle of the night)

...and
Code:
-D 0:0 -D 0:1 etc
are your friends....

...and
Code:
-S
safe mode may be fractionally slower, but it'll work until you've had some sleep.

The only thing I'm not sure is if it searches for all lines listed or does them one at a time?

Given that there are two bitcoin addresses per private key, that if you are iterating through private keys pseudo-randomly (i assume this is what vanitygen does, at the end of the day), it does seem that you may as well look at both the addresses each time you calculate a point on the curve for a given private key...

Only the initial key position is random, then vanitygen just increments the key by one for each additional address search. There is little cost to be saved there.

I prefer Zakir over Muhammed when mentioning me!
I have 5 prefix letters , what is the command line for find at least a BTC address for it ?

Case-sensitive prefix search:
Code:
"path\to\vanitygen.exe" 1Prefix

Case-insensitive prefix search (faster):
Code:
"path\to\vanitygen.exe" -i 1Prefix

Case-sensitive prefix search but not limited to 1 match:
Code:
"path\to\vanitygen.exe" -k 1Prefix

Case-sensitive prefix search but not limited to 1 match and saves all matches to a file:
Code:
"path\to\vanitygen.exe" -k -o anything 1Prefix

Note: If you want to save all matches to a file in the same folder Vanitygen is, specify the path to directory. Eg:- "path\to\vanitygen.exe" -k -o "path\to\anything" 1za

Edit: Searching for compressed key is faster than uncompressed key. Download Lifeboat's vanitygen. See https://bitcointalksearch.org/topic/create-vanity-bitcoin-addresses-four-times-as-fast-301068. Also, see https://bitcointalksearch.org/topic/m.10590011.

Case-sensitive prefix search but not limited to 1 match and saves all matches to a file (compressed):
Code:
"path\to\vanitygen.exe" -k -F compressed -o anything 1Prefix

What are command lines for oclvanitygen ? does oclvanitygen use graphic card for computing ? and this is faster than vanitygen ?

Commands are same except you will have to select OpenCL device using -D command. If you have only one OpenCL device and you did not specify, Oclvanitygen automatically chooses the device. Else, it will give you an error.

Eg:-

Code:
"path\to\oclvanitygen.exe" -D 0:0 -k -o anything 1Prefix

You know there's no BTC in this wallet https://blockchain.info/address/1Cii2e2wGejfrRHRCbaYTzmyPLpJwGvsgD (and it only every had about $50 at most ever?)

With a Quantum Computer, you'd be better off mining BitCoin blocks.  1,000 Billion is a Trillion BTW, thought you'd like to know that and a micro second... Well.... that's just silly....

No, there's no known quantum algorithm for solving a SHA256 hash. It would also be useless for address reversal (except possibly with reused addresses) since the pubkey isn't known, just the hash, until the first spend from said address. I'm also not sure if EC is breakable on a quantum computer (Shor's algorithm has a discrete log variant but I'm not sure if it's applicable here)

tspacepilot it seems this is exactly what I was looking for. Could you tell me where to add the piece you posted?

Thanks!
Nice topic to research.
the mayor changes will only have to be made in the function:
void *vg_thread_loop(void *arg).
In stead of the two options compress and uncompressed a combined flag could to be introduced/added as a valid command line flag.
When combined is active, only calculate (uncompressed) EC points for half the buffer.
Fill the other half with the equivalent compressed points.
for all other calculations use same flag to switch halfway between postprocessing (un)compressed settings.
The final address checks can stay the same.
In theory.... at least.

It will take a bit more work than just porting the example python code........
