python OpenCL bitcoin miner

[pogi23]

Hello, I am pogi23, and I have a problem...

Recently, I reinstalled SDK 2.1 (I use a Radeon 6770) on a WIN7-64 machine and now I seem to not be submitting any shares.  I use poclbm -v -w128  (ver.20110709) and I've double-checked my workers and my passwords.  I even tried switching from a PPS to a DGM worker and it just sits there.  I can see it crank out 205MH, the fan is going crazy but it just won't submit a share.

Any ideas would be greatly appreciated.  Thank you.

Go back to catalyst 12.1. SDK 2.1 doesnt work anymore for 12.6.

Hi guys.
When using poclbm through guiminer and viewing a video stream sometimes my computer crashes with a reference by pointer exception BSOD.
Is this a known issue? I can provide the crash logs if it would help...

thanks.

A new version is up with support for Stratum. See https://asktom.cf/index.php?topic=108533.0


I am also planning multi-miner support (GPU) as well as FPGA support.

I don't know Jack Didly Squat about poclbm.  But since it now has native stratum support I thought I'd give it a whirl.

Here are the messages I get when I try it.

Code:

stratum.btcguild.com:9332 18/09/2012 20:39:42, IO errors - 2, tolerance 2

stratum.btcguild.com:9332 18/09/2012 20:39:42, [Errno 9] Bad file descriptor

stratum.btcguild.com:9332 18/09/2012 20:39:45, IO errors - 3, tolerance 2

stratum.btcguild.com:9332 18/09/2012 20:39:45, No more backup pools left. Using
primary and starting over.

stratum.btcguild.com:9332 18/09/2012 20:39:45, Setting server (os2sam_CGMiner @
stratum.btcguild.com:9332)

stratum.btcguild.com:9332 [262.457 MH/s (~0 MH/s)] [Rej: 0/0 (0.00%)]

Any ideas if I'm doing something wrong, if something is wrong with the new poclbm or something with the stratum pool?

I was able to connect to BTC Guild with the standard protocol and port and it does work.  So the problem seems to lie somewhere in the stratum implementation.
Thanks,

Make sure when connecting to BTC Guild's stratum server, you use stratum:// as the prefix, not http://

Yep, did that.

Some guy on the BTC Guild thread made the same suggestion.

Any ETA on GBT support?

[m0mchil]

As always, some small fixes were needed. Please update with the latest version.

Hmm, I just downloaded today's build and am getting the same results as yesterdays.
Sam

Edit: I looked at my command line again and changed the upper case characters in my worker name to lower case and now it is working.

Thanks,
Sam

Again, new version is up. Main difference is it will always prefer Stratum now - for example if there is http:// specified, but server returns stratum address, it will be used.

[slush]

Thank you m0mchil for this release. I can confirm that it works with Stratum nicely now.

[eleuthria]

Yes, thank you m0mchil for being the first to adopt the Stratum protocol.  I finally edited one of my pool servers to include an x-stratum header and poclbm redirected nicely.

Can anyone show me the place in the poclbm source code:


where poclbm get the work from pool or bitcoin-qt

where poclbm increment the nonce and the coinbase

where poclbm compares the hash with the current target

where poclbm send back the data to the pool or bitcoin-qt

[slush]

I don't understand your question. If you can read python, you'll spend something like three minutes to find this out yourself. If you cannot read python, any advice to you is useless...

[slush]

where poclbm get the work from pool or bitcoin-qt

HttpTransport.py:getwork() or StratumTransport.py:queue_message

where poclbm increment the nonce and the coinbase

BitcoinMiner.py:mining_thread(), coinbase can be modified only on Stratum, it is StratumTransport.py:increment_nonce()

where poclbm compares the hash with the current target

BitcoinMiner.py:diff1_found() or Servers.py:send()

where poclbm send back the data to the pool or bitcoin-qt

Servers.py:send() or HttpTransport.py:send_internal() or StratumTransport.py:send_internal()

thank's

[betatest512]

is there a source code of poclbm with comment's

[betatest512]

can someone show me the line of code where the nonce is set

and the line of code where is nonce is incremented please show me the exact line as i know the function's it is in (mining_thread)

and can anyone tell me what does poclbm do after it has gone through all the nonce from 1 billion to 4 billion. what does it increment next. (and can you point out the line in code where it is incremented)

[electronus]

Just installed a new version of miner
on one of 4 5870 periodically got error:"You are reconnecting to long poll too fast" with some degradation of hashrate 
after restart - all ok... strange situation...
