How do I make it use my GPU?
I'm following an online guide and got to here.

it looks like -D 1:0

so like

oclvanitygen64.exe -o done.txt -k -D 1:0 1aaron

Doesn't work. It's fine. I'll just use the CPU one. Doesn't take that long anyway

[AlBoKa]

Someone testet Vanitygen performance on the new AMD Vega 64?

[LoyceV]

Ok it's enough. I give up. After 99.9% the Prob section disappeared and it's 12 more hours since then without results

I've been searching a long list of addresses for a while now. Once in a while it ends up like this:

Code:

Next match difficulty: 39007422227 (14732 prefixes)
[8.57 Mkey/s][total 266644488192][Prob 99.9%]

It reaches 99.9% much more often than it should, this should happen only once every 1000 searches on average. It feels like I get better results if I restart it when this happens, as if it has been stuck.
All settings remain the same. I think it might be a bug in oclvanitygen.

[K1773R]

no, thats randomness. its impossible to tell how "far" you are to find what your looking for, its just a very crude approximation. restarting it wont change anything, just reset that approximation.

[Biitcoin]

As OP is no longer active and SegWit kicked in, in order to be able to create SW Vanity addresses, a new software must be created for that matter?

Hello everybody
It's been 2 days since I've broken my head trying to solve the oclVanitygen problem more it does not want and I can not figure out why. Is that I hurt. Of course I am reader of this card and I have been read in less to less than 100 pages to try a little more it does not work :-( I think I have missed a detail or an idea that I did not I also have the latest NVIDIA driver (the 385.69 for GeForce GT 520M PILOTE may be too new) for my small GPU but I would like to see the difference with Vanitygen which suits it perfectly then I persevere but I need to have the latest version, Help me find car there really I can not get there.
I have assigned the GPU from the NVIDIA Command Center to the oclVanitygen.exe program but here is the error that brings me as a recurring member as well as command line options made. I still try -S -v 1TL // -v -S 1TL
NOTHING also does not start and the message is still the same

How could I get there ? thank you in advance for the tips

I would first check if this file calc_addrs.cl is located in the vanitygen folder

https://github.com/samr7/vanitygen/blob/master/calc_addrs.cl

[Lolo54]

yes i have it well in the vanitygen folder oclvanitygen.
but it does not change the result ca does not work and the message concerning kernfile and openCl is the same. I do not understand where the problem comes from

You might find some info here: https://www.reddit.com/r/Bitcoin/comments/1ii20b/after_about_7_hours_of_waiting_i_finally_got_the/


Did you try to copy the calc_addrs.cl to the main folder where you run ./vanitygen ?

[Lolo54]

yes i still run vanitygen as oclVanitygen from the same folder in which i did the extraction after downloading. In this folder are these 2 files
cacert.pem
calc_addrs.cl
For the file cal_addrs.cl I edited and saved from the link provided above
Here I just update driver and OpenCl library from this link
https://software.intel.com/en-us/articles/opencl-drivers
https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html
The intel drivers also support Nvidia cards unless specific extansions are in the code which is not my case.
However nothing changes I exactly the same messages
For the line of reddit actually I knew it already I had helped but without success also.

funny thing is, oclvanitygen.exe dont have -P for public key :s

[xhomerx10]

funny thing is, oclvanitygen.exe dont have -P for public key :s

 It might not show up in an options list but it still works.  I've used it many times.

[aarons6]

im guessing the answer is yes, but can i generate a bitcoin address and use it for bcc?

[LoyceV]

im guessing the answer is yes, but can i generate a bitcoin address and use it for bcc?

If by BCC you mean Bitcoin Cash, then yes, you can.
All vanity addresses with a balance at Fork time now also hold Bitcoin Cash.

[mrxtraf]

I made a new rack with cards amd Radeon rx 560 4 GB. One for 8 cards, 64 RAM, 8 cores, 16 streams. The second one with the same card. Purely for tests.
New clean OS. Kubuntu 17.04. Lates amd drivers for linux.
But there is still a moment when the program hangs on one of the cards. The moment of attack is from 40 minutes to several days.
But if with nvidia you could leave the application or kill it forcibly. In this case, not ctrl-C, not kill -9 does not help. Only reboot the entire operating system.
How to fix this?

Already treads is blocked at one card.

After several hours of work. Maybe an hour, maybe a day. The output of the current state stops.

But in the processes the task continues to be executed. It takes up part of the CPU time. And the calculation continues only on one of the cards. I tried to wait about a day, but nothing has changed.
After "^ C" it will stop after 20-30 seconds.

How get dump on worked programm on ubuntu konsole?
[/quote]

[AGD]

CPU load looks pretty high. If it works on 100% most of the time I would expect failures and system shutdown due to high CPU temperature.

[arulbero]

A couple of question about https://vanitypool.appspot.com/

1) How can I know if I have to use compressed or uncompressed keys for the search? For example, in this case:

https://vanitypool.appspot.com/availableWork   -->  11111111

can I use only compressed keys?


2) split -key generator feature: if I made a my own program that computes not only P + k*G (where P is the public key provided to start from) but  -(P + k*G) too, can I claim the reward?

If 's' is the secret private key of P (P=s*G), then the new private key would be :  -(s*G + k*G) =>  -(s+k) = n - (s+k)

where

n = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

is the group order of the curve.

WOW! 169 pages of technical details.. Sorry guys but i'm not much familiar with so deep technical things, but i know enough to generate address with vanity.

Can i ask only about one thing - is it safe or not? I mean do the private key is safe and only i can see it or...?
