What's wrong? why poclbm doesn't work?

POCLBM doesn't look so popular anymore

Poclbm is VERY popular, it is default backend in GUIminer - the most widespread miner around. But GUIminer has it own builds.

Is this still under development? I see an update or two quite recently at github, but no posts here in ages.

Yes, I still maintain the miner. It is now modular, i.e. you can implement your own hardware or work-source types. I just haven't released a py2exe recently (since BFL support actually) - POCLBM doesn't look so popular anymore and works fine for anyone able to setup python + pip and pull sources from github.

Whatever you improve for MacOS is welcome.

Is this still under development? I see an update or two quite recently at github, but no posts here in ages. I've managed to get vectors mode running on an OS X Lion Mac after much fiddling around and annoyance, and I'd like to either contribute back my cheap hack, or talk to someone who can help figure out the real way to fix the problem.

But if no one's actually going to care, I'll probably go back to banging my head against BFGMiner/CGMiner until either the bugs break or I do....

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 Huh

after restart - all ok... strange situation...

indeed... do you still get that error from time to time?

No, because I'm rolled back to old version, because of degradation of hashrate in new one. The degradation was seen by me even if there is no error at all, so I'll wait for another new version and compare again with stable ver (feb 2012)

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)

where poclbm get the work from pool or bitcoin-qt

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

Quote

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()

Quote

where poclbm compares the hash with the current target

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

Quote

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()

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...

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

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

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.

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.

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.

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

A new version is up with support for Stratum. See https://bitcointalksearch.org/topic/ann-stratum-mining-protocol-asic-ready-108533

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

Any ETA on GBT support?

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,
Sam

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.

Thanks,
Sam
