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

I'm using oclvanitygen64 and there doesn't appear to be a

Code:

-r

switch.

Yep, the GPU version cant do regex. Not sure why. Try

Code:

vanitygen64 -r test

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.

It does:

Quote

Invalid Character 'I' in prefix '1BIG'

I guess it depends on what you actually entered as neiter "small ell" not "big eye" are filtered for me. Are you using -r?

Code:

$ ./vanitygen -r '1BlG'
[154.22 Kkey/s][total 4432640]

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.

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 Cheesy

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!

Code:

Difficulty: 264104224
Compiling kernel, can take minutes...done!

Privkey: 5HrhdHG7LzJG1k1teTKbGRhNqZzU9LxMsYTUxoNoTmUb7frNmDB

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 Wink

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

# 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:

I don't know iff the blacklists are relevant.

I am running the Nvidia-driver:

check if this file exists:

Code:

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

does this exist too?

Code:

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:

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

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?

-snip-

Code:

>vanitygen64.exe -r [Aa]{2}1{2}$
Pattern: [Aa]{2}1{2}$
Address: 19VJ8Pmd5MB4EFJ2ovYX8nurgWiDeAA11
Privkey: 5KWwwpWcKhKcJPgePWCzeM6XKr3cZsTDTuRXiPQCM9HR1b6AaY2

Pattern: [Aa]{2}1{2}$
Address: 1QAkUcikHoeAGgzeg21BMFx627mfntAa11
Privkey: 5KiP18jvZotGWnPWRwXda9TJgKyzhQi48evVv7wMgX4144rcnrq

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}$
Address: 1QFjZXE28vaDN3NJdWpfY2GtKH9M279652
Address: 1Q54GaNGcAK2xAGuBteMyfaPyTtE884619
Address: 1PXZrNFjVefRAedPniRGKjMdAFpa933155

Address: 19yxjCfjwCJNfXjT5kkHoF6x7h5R876332

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'm hoping your guess is better than mine Undecided

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

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

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'

Remove the Intel OpenCL this way, seems you installed this manually...:

$ sudo rm /etc/ld.so.conf.d/opencl-vendor-intel.conf
$ sudo ldconfig

after this, go to the vanitygen folder:
$ make clean && make

Done

Quote

$ rm *.oclbin

The second command removes the compiled OpenCL kernel for your GPU which dosnt work anyway, always remove it when changing drivers/rebuilding, otherwise you'll end up using an old OpenCL kernel.

I have no file ending on oclbin.

Now back to your first line:

Quote

You will have to install the packages i've told you. nvidia-libopencl1-352 should show "installed".

Installing nvidia-libopencl1-352 removes ocl-lcd-libopencl1.

After this:

Code:

# dpkg --get-selections | grep opencl
nvidia-libopencl1-352 install
nvidia-opencl-icd-352 install
ocl-icd-libopencl1:amd64 deinstall
opencl-headers install

Quote

Now, try again and post the results.

I now get this:

Code:

make oclvanitygen
cc -ggdb -O3 -Wall -c -o oclvanitygen.o oclvanitygen.c
cc -ggdb -O3 -Wall -c -o oclengine.o oclengine.c
oclengine.c: In function ‘vg_ocl_prefix_check’:
oclengine.c:1553:18: warning: variable ‘tablesize’ set but not used [-Wunused-but-set-variable]

cc oclvanitygen.o oclengine.o pattern.o util.o -o oclvanitygen -ggdb -O3 -Wall -lpcre -lcrypto -lm -lpthread -lOpenCL
/usr/bin/ld: cannot find -lOpenCL
collect2: error: ld returned 1 exit status
make: *** [oclvanitygen] Error 1

Error "/usr/bin/ld: cannot find -lOpenCL" is what I've had before, and so far if I got rid of this error I got an oclvanitygen that can't find a platform.

Any more suggestions are much appreciated Wink

Now we need to know where your OpenCL lib is stored.

$ find /usr -name libOpenCL.so
