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

[LoyceV]

not skipping was correct. You'r binary is compiled and ready to go. Now we need to fix the last issue:

Thanks

is the package nvidia-modprobe installed? if not, install it.

Seems like it:

Code:

# lsmod | grep -i nvidia
nvidia               8646656  33
drm                   344064  7 i915,drm_kms_helper,nvidia

Code:

# find / | grep modprobe | grep -i nvidia
/etc/modprobe.d/nvidia-graphics-drivers.conf
/etc/modprobe.d/nvidia-352_hybrid.conf
/lib/nvidia-352/modprobe.conf

The contents of these files:

Code:

Laptop / # cat /etc/modprobe.d/nvidia-graphics-drivers.conf
# This file was installed by nvidia-352
# Do not edit this file manually

blacklist nouveau
blacklist lbm-nouveau

I don't know iff the blacklists are relevant.


I am running the Nvidia-driver:


Judging by this I would say my X-server knows the card:


And this is what I have installed:

check if this file exists:

Code:

$ ls -al /usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.1

does this exist too?

Code:

$ ls -al /etc/OpenCL/vendors/nvidia.icd

if not:

Code:

$ sudo mkdir -p /etc/OpenCL/vendors
$ sudo tee /etc/OpenCL/vendors/nvidia.icd <<< 'libnvidia-opencl.so.1'

I think this is all okay:

Code:

Laptop ~ # ls -al /usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.1
lrwxrwxrwx 1 root root 26 Nov 16 20:51 /usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.1 -> libnvidia-opencl.so.352.63

Anything else I can do/try? It's probably something really simple once you know it

All the vanity addresses are like : 1NAMExxxxxxxxxxxxxxxx

Is there a way that we can generate addresses which end in the desired way ?

For example : 1xxxxxxxxxxxxxNAME

If it is possible then whats the command line for windows?

If you dont use a GPU you can search for regex, the $ symbol means "at the end". Dont use the keys (obviously).

Code:

>vanitygen64.exe -r NAME$
Pattern: NAME$
Address: 1Lo79wpQy3QVZePzEaL818F1uhXLC2NAME
Privkey: 5JdvX473jNfr2LaYxsETj91E8aC1eiy17xAWkSTZ9g5om1dNLby

anywhere also works (and is obviously easier):

Code:

>vanitygen64.exe -r NAME
Pattern: NAME
Address: 1EpHNAMEFohF8UF9pmuGSLdNtSyc41CkEn
Privkey: 5J5fDUtVSiAwofjxpRcSKikhZzLjSSWbiE9kcPVyM4Lhhx7HrW6

You can also use more complex patterns.

Code:

>vanitygen64.exe -r [Aa]{2}1{2}$
Pattern: [Aa]{2}1{2}$
Address: 19VJ8Pmd5MB4EFJ2ovYX8nurgWiDeAA11

I didn't understand the last one. Can you explain what do characters inside the brackets indicate ?

[Aa] = A or a
{2} two symbols, so here it can be AA, Aa, aA or aa
1{2} means two ones.
$ must end with

so in total the possible results are all addresses that end on one of the following strings

AA11
Aa11
aA11
aa11

You could also do [0-9]{6,8}$ which would be 6, 7 or 8 numbers at the end, e.g.

Code:

Pattern: [0-9]{6,8}$

Make sure the expression is valid for a bitcoin address. You can search for [O0l] without ever finding a result.

[tspacepilot]

Make sure the expression is valid for a bitcoin address. You can search for [O0l] without ever finding a result.

That would actually be a good improvement for vanitygen, to do a validation step to ensure that what's being looked for actually could match a bitcoin address.  I haven't thought about the completeness of the problem but at the very least you could (as you point out) rule out any expressions which explicitly look for [O0I].  I don't think I have the code checked out at the moment or I'd consider submitting a pull request myself.

install the nvidia-modprobe package.

try to run the miner with sudo, as with a incorrect OpenCL setup, you'll need root to load the nvidia_uvm kernel module. Once loaded you dont need sudo again. Your missing that module, hence the failure.

This fixed it! Running once as root, compiling kernel, and now it runs as user too.
From 200-400 kkeys/s (depending on system load) to up to over 7.5 Mkeys/s! Thank you so much, that's 25 times faster on average!

Code:

Now the search continues It's running at 79 degrees C now, and slowly going up, After cleaning it a bit it runs at 62 degrees C now.

Edit: on performance: the GeForce 840M reaches just over 9 Mkeys/s if I close my browsers to reduce CPU (or video?) load.

you needed root to load the nvidia_uvm kernel module. with the nvidia-modprobe package installed, you can load the kernel module as user too or rather, it gets auto loaded.

If you use the GUI, obviously there will be less computing power for the OpenCL stuff. Some browsers use hardware accelerating which hinders oclvanitygen even more.

Have fun with vanitygen

I skipped this part of your previous comment since I got it working, but it sounds like an improvement.
When I google it, it simply says to `apt-get install nvidia-modprobe`, but it doesn't exist on my system. I now know it's something I should still fix, but for now I'm happy I can use it

[tspacepilot]

I wonder if you guys are just using different versions of the software.  Perhaps the filtering was added recently?

well, then you can either load the module yourself with modprobe, or run any OpenCL application with root and quit it again to load the module.

Code:

$ sudo modprobe nvidia_uvm

if you get any ohter issues, just drop a post or send me a private message.

[actmyname]

Haha, I managed to get lucky on this.

Generated 1ActBTCi5XUMjqnyFxVWgSfE5xWicj8g3o when I was trying to find a non-case-sensitive prefix of "actbtc". It was my first try of that result, in under 10 minutes. Thanks greatly for making this.

If I had more time or much faster computational power I'd go ahead and help other people or generate a full "1actmyname" prefix. (But even the non-case-sensitive of that takes 100+ days at my current speed)

[LoyceV]

I need 11 days for 50% chance for "1actmyname -i". Are you running on a fast CPU, or on a very slow GPU? If you use a fast CPU now, it may be possible to switch to your video card and get much more speed out of it (for me it added approximately 1 character in the same time).

Out of curiousity: what if the vanity pool finds the required address, but adds something bad behind it? Just bad luck for the person who bought the address? My search for 1faucets" ended up with an additional "uck" behind it. If someone pays good money for an address, they won't like it.

I just reread the last couple of pages - I didn't know about this feature - I'd use it for middle or especially end of addresses, but the GPU cards can kept doing the front prefix.

If I have the "1" eg "1name" will the -r look just at the front?
