python OpenCL bitcoin miner

[betatest512]

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)

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...

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)

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....

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.

[slush]

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.

[mmartoccia]

Hi guys, I've been at this all day and I'm struggling to get poclbm to work. Is fglrx really the issue or is it something else? Any help would be greatly appreciated.

Look like the setup.py isn't really installable

running 'python setup.py install' install only poclbm.py and not other py files, so it can't start.

Did you need help to create a correct setup for linux ? or you care only of windows py2exe release ?

[twobits]

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.

I know a few people that run poclbm in the background on windows mostly just to feel they are supporting an alternative to fiat.   They don't follow the scene at all  though. I just let them know when I see an update to the windows build to let them know to update.  We have been figuring that any worthwhile  updates would get check pointed by a build.  Is this not really true?  Have windows build updates ceased then?

[Nemo1024]

I'd like a Windows build as well.

I use my own front-end:
https://bitcointalk.org/index.php?topic=149442.0
http://stanislavs.org/bitcoin-miners-in-tray-miner-gui-manager/
, but I am forced to have GUIMiner for the sake of the bundled poclbm build, which supports HD 7970.

poclbm_py2exe_20120920.7z linked to in the opening comment gives the following error:

09.04.2013 20:54:27 [AMD HD7970]: Traceback (most recent call last):

The build, included with GUIMiner does not give any errors with the same parameters. I saw on github there were a few bugfix commits.

Can we have the latest and greatest build for Windows, please?

I get the same errors...
I second this, and would love to have an updated standalone package...at least if there is I can't find it

[Ruudsy]

Hey,

i switched from Windows to Ubuntu 12.04 and don't get poclbm running.

I installed ATI Drivers, 12.104 Catalyst as well as SDK 2.8, pyopencl is also running perfectly. But I don't get poclbm working.

The Error reaccurring all the time trying to run

Code:

sudo python poclbm.py http://xxxxxxxx:xxxx@api.mining.cz:8332 -d0 -v -w128

The terminal always says

Code:

Sounds like you need to allocate the correct DISPLAY(s) (the ones associated with your GPU(s) ) to the Xserver ... it's been so long i forget how to do it ... something like

Code:

export DISPLAY = 0.Y

... where Y is number associated with your GPU

[Ruudsy]

Tried that before, is not working unfortunatelly ...

Code:

sudo fglrxinfo

gives me this

Code:

display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 5800 Series 
OpenGL version string: 4.2.12217 Compatibility Profile Context 12.104

so I assume a

Code:

export DISPLAY=:0.0

is required? Or do I need

Code:

export DISPLAY=:0

?

Neither ist working ...

Here is everything in one piece:

Code:

xxx@Eibe:/opt/poclbm$ export DISPLAY=:0
xxx@Eibe:/opt/poclbm$ sudo python poclbm.py
