I have strange problem using vanityminer on windows 7

Code:
C:\Users\Deafboy\Apps\vanitygen>oclvanityminer.exe -p cypress -d 0 -u "https://vanitypool.appspot.com/getWork" -a 163fnJCLCX9R3x6XHsAcSRD2hnbD2cvP4P
Invalid character '     ' in prefix '                   ga.src = ('https'
Invalid character '     ' in prefix '                   ga.src = ('https'
No work available, sleeping
^C
C:\Users\Deafboy\Apps\vanitygen>

Should have used oclvanityminer64.exe and URL without /getwork

If I generate some addresses and send coins to them the balances will still be visible on a site like blockchain.info even if the private keys haven't been imported anywhere yet? I'm pretty sure the answer is yes, but figured it couldn't hurt to ask.

Also, if I import the private key into a wallet will it cause any problems if that private key gets imported into a different wallet later on? I think that just means both wallets can control the coins associated with the addresses, but that it shouldn't mess anything up. Not sure on that point.

I have added the ability to dump the pub key when using verbose mode:

Check it out for debugging purposes !

Should I be concerned that vanitygen is a multi-threaded OpenSSL-based application that doesn't seem to call CRYPTO_set_locking_callback ?

Ah, maybe it gets away with it because the non-threadsafe calls to OpenSSL are inside other locking anyway....

Here is a question for someone more knowledgeable than I.

I have limited/no internet connection.

I want to try and solve some work from the vanitypool. To start with i found a public key with multiple search patterns on the available work site, saved the patterns in a file on the computer.
I then ran oclvanitygen using -f to search the file with patterns, and -P with the common public key.
The output I got from this I tried to manually insert back into the solved section of the vanity pool site however it said solution doesn't match pattern.

Spoke to ThePiachu and it was suggested it was because i used oclvanitygen not oclvantiyminer.

So my question: is there anyway to do a similar set up with oclvanityminer? As I can't get it to work without requiring a url and an address. But I don’t have internet for that, or can I set up oclvantiygen to correctly get me the privkeypart so I can manually upload them and they be accepted?

I am not sure why using oclvanitygen, with -P as the pubkey and finding the right pattern produced a privkeypart that wasn't accepted.

How do I get this (or other versions) to generate other alt-coins? Litecoins begin with L and Bytecoins begin with 8 and Tagcoins begin with T, for example.

Use this page: https://en.bitcoin.it/wiki/List_of_address_prefixes

EXAMPLE:

Code:
oclvanitygen -D 0:0 -i -k -o found664.txt -X 23 Atri11ium

You must then test the address by importing the privkey and then testing it with a (small) quantity of coin.

I've started to experience this as well, I have concluded this problem is related to newer drivers (eg 13.xx). I had this card working great with v 12.8 Radeon drivers, as have many others.

Greetings.
According to oclvanitygen.c :
'"By default, <pattern> is interpreted as an exact prefix.\n"'
But is there any possibility to use the vanitygen on an OpenCL device to find address not only by prefix, but, for example, by suffix or postfix or regex.

For example not like "1Love.*" but like "1.*Love"?

samr7 doesn't seem to have touched his repo in a while.  I went ahead and forked his repo and merged in pretty much all the public branches on github.  I've done some quick tests, and there were no merge conflicts, but it's possible I combined some incompatible things.  

https://github.com/samr7/vanitygen/network has lots of pretty colored lines connecting to one branch now.  I also updated my OSX brew tap (`brew tap WyseNynja/bitcoin && brew install WyseNynja/bitcoin/vanitygen`) to include my branch of vanitygen which I tagged version 0.23-red.  It worked for me on Mavericks and it uses brew's openssl.  I added the red suffix just in case someone else has already done this and I just missed it in my cursory searching.

I think it would be possible, but I know regex would be a lot slower.

Do you have a precompiled OSX build of Vanitygen?

I don't ever want to underestimate my own stupidity, much less publicly proclaim it, but here goes:

I'm generating vanity addresses to give out bitcoin for holiday gifts. I'm using oclvanitygen (since some of the prefixes are kinda long...)

So here's my 1st world problem:

I'm doing this on my laptop with an nvidia card (that is otherwise unused). It's running just fine, except sometimes the laptop overheats from the GPU and shuts down.

Is there some flag that I can use to throttle GPU usage with oclvanitygen?

./oclvanitygen -h
oclVanitygen 0.23-red (OpenSSL 1.0.1 14 Mar 2012)
Usage: ./oclvanitygen [-vqrik1NTS] [-d <device>] [-f <filename>|-] [<pattern>...]
Generates a bitcoin receiving address matching <pattern>, and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default, <pattern> is interpreted as an exact prefix.
By default, if no device is specified, and the system has exactly one OpenCL
device, it will be selected automatically, otherwise if the system has
multiple OpenCL devices and no device is specified, an error will be
reported.  To use multiple devices simultaneously, specify the -D option for
each device.

Options:
-v            Verbose output
-q            Quiet output
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-1            Stop after first match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X <version>  Generate address with the given version
-F <format>   Generate address with the given format (pubkey, compressed)
-e            Encrypt private keys, prompt for password
-E <password> Encrypt private keys with <password> (UNSAFE)
-P <pubkey>   Use split-key method with <pubkey> as base public key
-p <platform> Select OpenCL platform
-d <device>   Select OpenCL device
-D <devstr>   Use OpenCL device, identified by device string
              Form: <platform>:<devicenumber>[,<options>]
              Example: 0:0,grid=1024x1024
-S            Safe mode, disable OpenCL loop unrolling optimizations
-w <worksize> Set work items per thread in a work unit
-t <threads>  Set target thread count per multiprocessor
-g <x>x<y>    Set grid size
-b <invsize>  Set modular inverse ops per thread
-V            Enable kernel/OpenCL/hardware verification (SLOW)
-f <file>     File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o <file>     Write pattern matches to <file>
-s <file>     Seed random number generator from <file>

Would the -w, -g or -t switches/options be what I'm looking for? I'm unsure what exactly each means in the context of this program. Would anyone feel like pulling out their hand-puppets to explain them to me? (I'm guessing that -t is only for CPU usage, not GPU... and subsequently assuming that -b is somehow related to that?)

I'm trying to cobble together something that watches psensor and sends a kill -STOP or a kill -CONT to the actual process, but if there's something I'm missing, I'm all ears!

TIA, folks...

The best way, imo, would be to write a powershell script that watches the hardware temp and kills/restarts the process when thresholds are crossed.
