Title: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 25, 2013, 01:04:48 AM From http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars :
"to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen (https://en.bitcoin.it/wiki/Vanitygen) in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) We also added support for compressed keys as well. You can download it for free at http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA that begins with 1Lifeboat. PGP signature for program is here (https://lifeboat.com/oclvanitygen.zip.sig)." Note that a high-end AMD card is defined as an AMD Radeon 7xxx GPU or greater. If you have a slower card then you can just download oclvanitygen as described at https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen. Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.) Title: Re: Create vanity bitcoin addresses four times as fast Post by: Cudahuda on September 25, 2013, 01:47:23 AM Wow, impressive improvement!
Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 25, 2013, 01:56:24 AM Wow, impressive improvement! Thanks! Maybe we will finally get a 1Lifeboat address from our high-end AMD card. We have been trying to get such an address for over 5 months — most of the time with the original slow version of oclvanitygen. Currently we have gotten 3 1Lifeboat addresses (in just 2 weeks!) from an ancient HP xw4400 workstation that was built in 2006. The trick being that it has a high-end NVIDIA card and also we got a bit lucky with it. (You want to try for more than 1Lifeboat address as some addresses look better than others. For example, our first 1Lifeboat address was 1LifeboatdUHD5eepYdcZZ57VjcwJU6CtB which could be read as 1Lifeboat, duh.) Title: Re: Create vanity bitcoin addresses four times as fast Post by: cypherdoc on September 25, 2013, 02:58:08 AM how will it work with 6970's?
Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 25, 2013, 03:08:08 AM how will it work with 6970's? It is my impression that only 7xxx's cause oclvanitygen problems. This is mostly due to development on oclvanitygen being halted 2 years ago so it was designed for the cards of the time. You should be able to download the regular version of oclvanitygen from https://en.bitcoin.it/wiki/Vanitygen and it should be fine. With 7xxx's you are forced to run the original version of oclvanitygen in slow mode which is *really* slow.

Also, as GPU bitcoin mining gets more difficult, this gives you a new way to use the power of your GPU that is bitcoin-related.

Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 25, 2013, 11:51:53 PM I was hoping it could help my Nvidia, but seems unaffected, same speed, can you do something for us nvidia users or it's impossible? :P Our fix only affects high-end AMD cards. On the positive side, NVIDIA cards have no problems at all running with oclvanitygen. For example, we are getting 28 Mkey/s with our EVGA GeForce GTX770 2GB running on an ancient 7 year old HP xw4400 workstation and that is the machine that generated our 1Lifeboatu7Y9YqKQRcXfjWYJdXog9CS7r address. We are currently getting about 22 Mkey/s from our Sapphire Radeon HD 7950 3GB. Before our fix to oclvanitygen, we were only getting 6 Mkey/s out of it which was painful. Title: Re: Create vanity bitcoin addresses four times as fast Post by: Dabs on September 26, 2013, 12:53:22 AM I'm running it on CPU, and getting 80 Kkeys. so.... hehehehe..
@lifeboat, does yours make compressed keys? the private keys that begin with letter L or letter K instead of number 5? Title: Re: Create vanity bitcoin addresses four times as fast Post by: p2pbucks on September 26, 2013, 02:02:51 AM ;) i put this up on my site , http://p2pbucks.com/?p=7958 (http://p2pbucks.com/?p=7958) .

I don't know much about compressed keys, but I checked and there seems to be a version of oclvanitygen at https://github.com/scintill/vanitygen/tree/compressed_opencl that handles compressed keys. I could compile a Windows version of it if there was much demand.

I could compile a Windows version of it if there was much demand. Compressed keys are better for you because you use up less bytes for every transaction. You put less data in the blockchain. And you end up paying less transaction fees. Title: Re: Create vanity bitcoin addresses four times as fast Post by: ratty on September 26, 2013, 10:45:23 AM I'd love one that made compressed keys as well.
Though I can't even get this one to work, I'm using an Windows 7 + Radeon HD 7800 + Catalyst 13.9 + "AMD APP SDK v2.8" which is supposed to be the SDK from 12.10 (http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/download-archive/). It just does the usual thing where it seems to find a match but doesn't print anything. Did I do anything obviously wrong? The catalyst 12.10 drivers won't even run on this card, but the first post said you could use the APP SDK from 12.10, which I thought I did. Have other people gotten this to work on a modern AMD card? Am I using the wrong version of something somewhere? Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 26, 2013, 08:30:34 PM @lifeboat, does yours make compressed keys? the private keys that begin with letter L or letter K instead of number 5? http://lifeboat.com/oclvanitygen has now been updated. To create compressed keys use the "-F compressed" option as in: oclvanitygen -F compressed -d 0 1Life or vanitygen -F compressed 1Life (So we also added a vanitygen program for those of you with no GPUs.) Title: Re: Create vanity bitcoin addresses four times as fast Post by: Dabs on September 27, 2013, 01:13:58 AM Just because: can you kindly do a md5 sum, sha1 sum or sha256 sum (or all 3) of the zip and the individual files. Then GPG sign the whole list?
and oh, I just tried to run it. It's not a win32 app? it's 64 bit? heheheh.. Do I need to upgrade my OS to 64 bit? (I have 2 old laptops running Win XP 32 bit.) I do have Win 7 64 bit, but I never installed it as I don't have more than 4 gig of ram. Title: Re: Create vanity bitcoin addresses four times as fast Post by: ratty on September 27, 2013, 01:16:46 AM Thank you so much! Works great on my old Radeon 4800. Its equally as broken on my 7800 as the original oclvanitygen with SDK 12.10. At least I can make compressed addresses on my older computer, so progress has been made!
Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 27, 2013, 01:30:43 AM I'd love one that made compressed keys as well. We now have compressed keys support at http://lifeboat.com/oclvanitygen To create compressed keys use the "-F compressed" option as in: oclvanitygen -F compressed -d 0 1Life or vanitygen -F compressed 1Life (So we also added a vanitygen program for those of you with no GPUs.) Though I can't even get this one to work, I'm using an Windows 7 + Radeon HD 7800 + Catalyst 13.9 + "AMD APP SDK v2.8" which is supposed to be the SDK from 12.10 (http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/download-archive/). It just does the usual thing where it seems to find a match but doesn't print anything. Did I do anything obviously wrong? The catalyst 12.10 drivers won't even run on this card, but the first post said you could use the APP SDK from 12.10, which I thought I did. Sounds like you have a challenge ahead of you. (AMD driver issues can be fun!) It is our impression that all Radeon HD 7XXX cards should behave the same for drivers and programs. We happened to have a Radeon HD 7850 lying around from earlier tests so we just installed it and it does work fine with our version of oclvanitygen. So the first question is: Are you trying a long enough bitcoin address? It should be at least four characters long to get stable results. So 1Life should be good for example. The next question is: Does using the option -S enable you to get results? The next question is: How could the catalyst 12.10 drivers not even run on your card? What error do you get? Note that it is difficult to downgrade your AMD drivers. After uninstalling your current drivers, we recommend that you run the following batch file before then trying to install the old catalyst drivers: cd C:\Windows\System32 del SlotMaximizerAg.dll del SlotMaximizerBe.dll del amdocl64.dll del OpenCL.dll del OpenVideo64.dll del OVDecode64.dll cd C:\Windows\SysWOW64 del SlotMaximizerAg.dll del SlotMaximizerBe.dll del amdocl.dll del OpenCL.dll del OpenVideo.dll del OVDecode.dll rmdir C:\ProgramData\AMD\KDB /S /Q I would recommend first trying to get the old drivers to work on your machine before you go for the more complicated option of running the old APP SDK plus the new drivers.

One more question, exactly which graphics card are you using? Is it a Radeon HD 7800M? Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on September 27, 2013, 01:47:51 AM and oh, I just tried to run it. It's not a win32 app? it's 64 bit? heheheh..

We've been testing it on 64 bit systems although dumpbin /headers claims that both programs that we are providing are 32 bit programs. Assuming it is a 64 bit program, do note that would enable the non GPU version (vanitygen) to run 50% faster as vanitygen does a lot of large integer arithmetic. What error are you getting?

One more question, exactly which graphics card are you using? Is it a Radeon HD 7800M? I looked it up from the invoice from when I purchased it a year ago, it's a 7850. Here's the info page from where I purchased it: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121623 I tried generating 1Life and it finds it over and over but never prints the key. Another clue I have that something is broken, is the kernel it makes is 700K. On my older card it makes one that is 3.8MB. If I use -S on my 7850 I get a 400K kernel with the same broken results. Now that you're telling me the Catalyst 12 drivers are supposed to work on a 7800 series, I will give that another try, this time with more confidence! I'll try that batch file too. Thanks for the help!

Title: Re: Create vanity bitcoin addresses four times as fast Post by: ratty on September 27, 2013, 03:49:16 AM The downgrade to Catalyst 12 worked, maybe I needed to do that batch file, but it works now.
I tried upgrading to 13.9 without clicking on upgrading the APP SDK, but that still broke it. Oh well, at least I can make it work now!

When you upgrade to 13.9, select Custom and not Express for the installation and then make sure it doesn't install a new APP SDK. It is fascinating that the wrong version of Catalyst will cause oclvanitygen to malfunction in that bizarre way.

But thanks to that batch file you pasted, I installed Catalyst 12.10, then backed up OpenCL.dll, amdocl*.* from both system32 and syswow64. I did the upgrade to 13.9, then restored just those files and now everything works perfectly. I'm in Catalyst 13.9 and I can oclvanitygen.

(uninstalling and installing different drivers/versions)
It works, but always without finding an address. My computer is a I5 Windows 8 64, with 1 7870 and 1 7950. Both cards works but always repeats the message GPU and CPU hash, without end. Any complete solution/guide?

I was able to use this on my 6950 after downgrading to catalyst 12.10 mentioned a couple of posts up.
Is there any chance you can build oclvanityminer64 as well? I'd be happy to donate some of the profits if I ever find any! I thought I had managed to build it, and ended up with a (32bit) binary, but it just wouldn't run (Windows error saying "The application was unable to start correctly (0xc000007b). Click OK to close the application"). I had some issues building libcurl, I think that's where it went wrong. The readme doesn't mention it and it's just assumed in the makefile... I haven't dabbled in that area of programming in a number years, so I could be forgetting something pretty simple. Or if you didn't want to build it for me but have an idea what I'm doing wrong, I'd happily accept some advice! :) Title: Re: Create vanity bitcoin addresses four times as fast Post by: BitDreams on November 23, 2013, 01:56:05 AM Mine is probably in poor taste but there's a story behind it.

You want to be sure that all DLLs are the same bit width as your .exe. You also want to be sure that your libraries are of the same bit width. And yes, this can be a pain-in-the-butt to pull off. (In our http://lifeboat.com/oclvanitygen we had to rename our 64-bit version of libeay32.dll to libeay64.dll and then alter oclvanitygen64.exe and vanitygen64.exe so they looked for libeay64.dll instead of libeay32.dll. If we didn't do this they would try to use the 32-bit version of libeay32.dll and crash.) If you make a donation at https://lifeboat.com/ex/bitcoin, we would be glad to put some effort into oclvanityminer64. Title: Re: Create vanity bitcoin addresses four times as fast Post by: btcpleb on November 24, 2013, 04:58:36 AM Unfortunately I cant afford to donate at this time, unless you'd accept about 6 cents worth of bitcoin unless you would accept a feathercoin I mined :P
Thanks for your tip, I managed to build through Cygwin (way easier and I felt a bit more at home) but my oclvanitygen is doing the mismatched CPU/GPU hash thing (even with the change in the github issue, but to the compressed_opencl branch). I suspect this is because I statically linked the APP libraries (your version worked flawlessly with my DLLs). I'm going to try downloading archived versions of the APP libraries and see if they work before trying to dynamically link them (I don't want a catalyst/APP upgrade to break compatibility). Edit: I've managed to get a 32bit version working perfectly. Not sure I'll bother spending time to get a 64bit version. Happy to share on request. :) Title: Re: Create vanity bitcoin addresses four times as fast Post by: zhinkk on December 08, 2013, 04:05:04 PM Having a strange issue. I run:
Code: vanitygen 1a Then I run: Code: oclvanitygen.exe -d 0 1a It shows over 10 Mkey/s but even after 5 minutes it can't find a address with pattern "1a". Why is this? I'm using Catalyst 13.11. I didn't install any seperate SDK's so I'm guessing I'm using the ones that came with it. The kernel DOES compile though and the oclvanitygen program still runs. Does this mean I have to install the SDK? I thought if I didn't have the proper SDK it would just crash, not a situation where it can't find a patterned key. You can see the verbose output here: Code: C:\Users\sdfzxcq\Downloads\oclvanitygen>oclvanitygen.exe -d 0 -v 1a Title: Re: Create vanity bitcoin addresses four times as fast Post by: ratty on December 09, 2013, 03:17:06 AM If you see CPU hash or GPU hash, that means it is broken, so you can kill the program immediately if you see that.

Actually all the characters in 1Dogewow are legal so I'm not sure what you are talking about. You misunderstood me completely. I wasn't asserting anything, I was just asking if illegal characters actually break anything. If an implementation ignored it and generated an address with 1, L, 0 or o, would every program just reject it, or would they not care? I have seen bitcoin addresses with those supposedly illegal characters, so it got me wondering what would happen if vanitygen generated these for various altcoins. I would love to try it and test if the safety check could be disabled. Or does bitcoin and all altcoins use a slightly different addressing system that allows bitcoin addresses to have "o" in them? If this just bores you, don't worry about it, just move on. No need to waste time on it unless it is interesting to you.

Title: Re: Create vanity bitcoin addresses four times as fast Post by: Trance on January 24, 2014, 11:54:25 AM From http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars : "to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen (https://en.bitcoin.it/wiki/Vanitygen) in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) We also added support for compressed keys as well. You can download it for free at http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1Lifeboatu7Y9YqKQRcXfjWYJdXog9CS7r that begins with 1Lifeboat. PGP signature for program is here (https://lifeboat.com/oclvanitygen.zip.sig)." Note that a high-end AMD card is defined as an AMD Radeon 7xxx GPU or greater. If you have a slower card then you can just download oclvanitygen as described at https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen. Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.) This is beyond great! Thank you for your hard work and efforts!

Title: Re: Create vanity bitcoin addresses four times as fast Post by: lifeboat on January 28, 2014, 12:37:14 PM whats the biggest wordlist you guys are able to load that actually works? If you are asking how long of a word you can specify and get, at Lifeboat we have gotten 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA and we use the phrase "Become a Lifeboat VIP and donate to bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA". So 1Lifeboat was specified, we got many results, and are currently using a 1LifeboatVP match which is pretty cool. Title: Re: Create vanity bitcoin addresses four times as fast Post by: deepceleron on January 28, 2014, 07:17:51 PM That's not what he's asking.
The length depends on how many case insensitive options there are for each word, along with the length of words and video card RAM. Case insensitive searches are unrolled into all possible matches; they consume the same resources as specifying all 100 or 1000 matching addresses. I have a 12-13 character long word list, and case insensitive searches on it were limited to about 4000 entries. Shorter words can be tens of thousands in a list.

Title: Re: Create vanity bitcoin addresses four times as fast Post by: micax1 on June 09, 2014, 08:40:57 PM I also get awful luck, going to 98% probability 4 times with still no match. I also get these messages: Match idx: 5 CPU hash: etc. GPU hash: etc. The hashes and match idx numbers change everytime. Is this normal? Nope, you are wasting your GPUs work, try to downgrade your driver to 12.10 (they contain a compatible SDK version) I have same problem.

Not a programmer but curious.. how did you manage to do it 4 times faster ??? anyways downloadingf now! Title: Re: Create vanity bitcoin addresses four times as fast Post by: lailiangufkjf65 on June 10, 2014, 02:56:54 AM From http://lifeboat.com/ex/press.releases.bitcoins.hundred.thousand.dollars : I was able to change pattern.c, but am having so much trouble getting it to compile correctly."to give back to the bitcoin community, Lifeboat Foundation has created the first Windows version of oclvanitygen (https://en.bitcoin.it/wiki/Vanitygen) in the world that runs well on high-end AMD cards. (Our version runs nearly four times as fast as the old version!) We also added support for compressed keys as well. You can download it for free at http://lifeboat.com/oclvanitygen and can learn more about what we did on GitHub at https://github.com/samr7/vanitygen/issues/19. oclvanitygen is used to create vanity bitcoin addresses such as our bitcoin address 1LifeboatVPg24QghZ73Dzrx8AxcJLCnoA that begins with 1Lifeboat. PGP signature for program is here (https://lifeboat.com/oclvanitygen.zip.sig)." Note that a high-end AMD card is defined as an AMD Radeon 7xxx GPU or greater. If you have a slower card then you can just download oclvanitygen as described at https://en.bitcoin.it/wiki/Vanitygen And if you need a Linux fix for high-end AMD cards, read https://github.com/samr7/vanitygen/issues/19 to learn how to fix oclvanitygen. Finally, oclvanitygen, no matter what the operating system, hates the latest AMD Catalyst drivers. So if, for example, you are running Catalyst 13.9, you would also want to use the AMD APP SDK Runtime from Catalyst 12.10. (So all your Catalyst drivers would be brand new except for the SDK Runtime.)

Post by: KrakenTrader on June 24, 2014, 12:52:46 AM Hi all
I was playing with oclvanitygen64 and vanitygen64 for a day or so, and all works fine so far. I like it a lot. Thanks to the devs ! Here is my QUESTION, if someone could respond please with some insights? I want to create 2 BTC addresses both starting with a prefix of the same length(7) using the same parameters: (1) oclvanitygen64.exe -v -o output.txt 1BTCUSD (Prefix difficulty: 15058417127) (2) oclvanitygen64.exe -v -o output.txt 1TRADER (Prefix difficulty: 888446610538) = ca. 60x higher Now, to create 1TRADER it takes around 60x longer (WTF?!?) than to create 1BTCUSD I was assuming, calculating prefixes with the same length ( here: length=7) using the same parameters "1ABCDEF" "1234567" "1TRADER" "1BTCUSD" etc.... would have the same difficulty and thus the same probability to finish the task after more or less the same time But, that is not the case for my example. So why should it be more difficult and would take around 60 times longer to find 1TRADER than 1BTCUSD ? Here are the detailed screen dumps (test for both was done on the same machine: windows 8.1 64bit i7 8core each 3.5GHz sporting a NVIDIA GeForce GTX 650) ----------------------------------------------------- oclvanitygen64.exe -v -o output.txt 1BTCUSD Prefix difficulty: 15058417127 1BTCUSD Difficulty: 15058417127 Device: GeForce GTX 650 Vendor: NVIDIA Corporation (10de) Driver: 331.65 Profile: FULL_PROFILE Version: OpenCL 1.1 CUDA Max compute units: 2 Max workgroup size: 1024 Global memory: 1073741824 Max allocation: 268435456 OpenCL compiler flags: -DPRAGMA_UNROLL -cl-nv-verbose Loading kernel binary 00473ecd85a40ab3481d30c8ef3aa08c.oc Grid size: 2048x1024 Modular inverse: 2048 threads, 1024 ops each Using OpenCL prefix matcher GPU idle: 3.19% [6.72 Mkey/s][total 81788928][Prob 0.5%][50% in 25.7min] oclvanitygen64.exe -v -o output.txt 1TRADER Prefix difficulty: 888446610538 1TRADER Difficulty: 888446610538 Device: GeForce GTX 650 Vendor: NVIDIA Corporation (10de) Driver: 331.65 Profile: FULL_PROFILE Version: OpenCL 1.1 CUDA Max compute units: 2 Max workgroup size: 1024 Global memory: 1073741824 Max allocation: 268435456 OpenCL compiler flags: -DPRAGMA_UNROLL -cl-nv-verbose Loading kernel binary 00473ecd85a40ab3481d30c8ef3aa08c Grid size: 2048x1024 Modular inverse: 2048 threads, 1024 ops each Using OpenCL prefix matcher GPU idle: 3.30% [6.74 Mkey/s][total 90177536][Prob 0.0%][50% in 1.1d] Thanks in advance :) Title: Re: Create vanity bitcoin addresses four times as fast Post by: TheRealSteve on June 24, 2014, 01:04:16 AM Now, to create 1TRADER it takes around 60x longer (WTF?!?) than to create 1BTCUSD You'll want to read this: https://bitcointalk.org/index.php?topic=25804.msg2606437#msg2606437 and this: http://bitcoin.stackexchange.com/questions/22748/if-bitcoin-addresses-are-truely-random-then-why-are-some-more-difficult-to-gene/22786#22786 tl;dr: some prefixes are simply less likely to occur.

Likely because the signature is invalid for the file - the sig is from about a week before the zip's date. Probably just from a small change in the README, but there's no way to verify that. I haven't noticed any suspicious activity, but I tend to use bitcoin things offline just in case anyway.You can always try making the changes yourself; there's a bunch of comments from the lifeboat foundation ( https://github.com/samr7/vanitygen/issues/19) in the samr7 repo, as well as some posts here; https://bitcointalk.org/index.php?topic=301068.msg3581899#msg3581899 The user lifeboat doesn't appear to have posted in a while - projects_coordination at lifeboat.com is probably the e-mail address most likely to get you to the people involved in the build and this thread.

Unfortunately I'm never going to be able to use this address miners because I don't want to risk it againUnless they come out with newer driver support. You aren't going to break video cards with drivers. You will break them by overheat though and lower the life running them at 100% usage (video cards run at a lower voltage and clock speed when they aren't doing work). The best advice is to keep them cool with lots of fans, and dust free by using case filters or regularly blowing or vacuuming the dust out of their heat sink fins.
