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.

How about telling us what didnt work and provide more information? Otherwise you wont get help.

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?

Has the HD5870 been superseded yet as the best vanity miner?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?

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.

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.
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 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.

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...

Our family was terrorized by Homeland Security.  Read all about it here:  http://www.jmwagner.com/ and http://www.burtw.com/  Any donations to help us recover from the $300,000 in legal fees and forced donations to the Federal Asset Forfeiture slush fund are greatly appreciated!

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.

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?

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.

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

cmd, C:\Users\XX\Desktop\t\oclvanitygen.exe -d 0 -i Hello
error loading kernel file 'calc_addrs.cl': No such file or directory
Where are you running the command from?  If it's from another directory, a shortcut, or batch file, or anything like that, there's a chance that the working directory is not "C:\Users\XX\Desktop\t\".  "C:\Users\XX\Desktop\t\" has to be the working directory for oclvanitygen to find that file.

Easiest way to make sure is by opening a command prompt, navigating to that directory, and then running it;
Code:
start > run > cmd (or equivalent)
C:\> cd C:\Users\XX\Desktop\t\
C:\Users\XX\Desktop\t\> oclvanitygen.exe -d 0 -i He110
( Note that you can't use the lowercase letter L - unrelated to this error, but just in case Smiley )

C:\Users\XX\Desktop\t\>oclvanitygen.exe -d 0 -o Test.txt 1ABE


C:\Users\XX\Desktop\t\Test.txt - - does not exist



It should be there but if not try changing your line to

C:\Users\XX\Desktop\t\>oclvanitygen.exe -d 0 -o C:\Users\XX\Desktop\t\Test.txt 1ABE

Include the path

Just thinking now, is not maybe a problem with not having administrator right to save in that folder?

If that does not work try and save it somewhere else like -0 C:\Temp\Test.txt
