Interested in this too. Hope we get a comprehensive answer.

There is an answer, just five pages back: https://bt.irlbtc.com/view/25804.msg611858#msg611858

It's about 58 times more likely to find addresses that start with your pattern. You could do a filtering step afterwards…

I meant: Just use vanitygen to generate addresses with your digits. You will get a lot of addresses which start with your pattern, and only some that have your pattern somewhere in between. It doesn't matter how long the digit sequence is. Then afterwards you can filter the resulting list.

I haven't tried regex matching with vanitygen, so I don't know if it can work. What you describes sounds like a bug.

After reading more carefully what you really want is:

    \A1TCa[1-9]{4}

I just tried it and it works.

Thanks for your help.  \A instead of ^ for start of string.  I likely wouldn't have got that.

Is this true?  I have never set up for GPU vanity generation but I always just assumed that you could - if you want to - use regular expressions on the GPU version.  Of course all that checking of the results would slow you down but that is the price you would pay.

So in D&Ts case match for exactly 1TCa, store them in a file, grep for those that happened to have 4 digits after the 1TCa offline later.  Sounds like a very large file with a few good ones in it

Hello everyone, I have a few (noob) questions

- Anyone know how to use all GPUs for oclvanitygen?
And why if I select GPU #2,for ex.:

oclvanitygen -r -d=2 123

Only my primary GPU (GPU #0) will be used? In my case this is a slower GPU.

- Why with -r only the CPU can be used (vanitygen prints "WARNING: Using CPU pattern matcher")?

- Are there any better/faster address generators out there?

- Why I can only generate addresses starting with "1"? Aren't there anymore addresses left starting with "3"?

- Why am I getting higher speeds without "-r" on CPU?
Without: ~350kkeys/sec
With: ~75kkeys/sec
Isn't it supposed to be the other way around (expression can be placed anywhere in the address instead just at the beginning)? Or am I getting something wrong?

- I have a Q9300 undervolted to 0.975V and underclocked to 2GHz to save power (stock 2.5GHz and sth like 1.1 or 1.2Vcore), before mining this used to be primarily a gaming rig, and I had this CPU running @ 3.5GHz and 1.32Vcore, what speed can I expect if I decide to O/C it back to 3.5GHz? I think it'll increase linearly but not sure and will probably do it unless I find a way to generate addresses with the "-r" option.

- Any way to generate shorter addresses (shortest as possible, 25 base58 chars?)

Thanks.

So there's no way to make use of all GPUs simulatenously?
Or maybe I could be running 3 instances of oclvanitygen each for each GPU to increase the probability of finding an address and it's priv key? Would that be the same?
