python OpenCL bitcoin miner

[m0mchil]

New version, please update.

Changes:

- using httplib + json, keep-alive
- optional verbose output suitable for redirection to log file
- version in code
- handler methods for hash rate, difficulty=1 candidate checks, failure

Do you know what's changed since poclbm_py2exe_20101126 so the new version doesn't works correctly anymore on slave core of 5970 in Windows ?
Current version works fine on primary core, but after finding first "accepted" share on slave core it starts flooding console with that "check hardware" error. Older, poclbm_py2exe_20101126 version works on both cores...

Yes, I'm aware of this problem. Unfortunately I'm still unable to resolve it. Any help from someone with 5970 on windows will be appreciated. The problem does not exist on Linux, but I can't figure out why it appeared on Windows only after the 20101126 release.

Just wondering if there's any more info on these changes,
I didn't see anything related to hash rate in the -help documentation, I'm probably missing something, just wondered if theres any more info on what these changes entail? Thanks for any info

Just wondering if there's any more info on these changes...

Keep-alive reuses same connection if the other party (pool) supports it. Using python standard libraries 'httplib' and 'json' makes poclbm to not depend on python-jsonrpc anymore. I was actually unaware that there is 'json' in python.

If '--verbose' is specified there are no more '\r' (carriage returns) in output. You can redirect all output to file (poclbm [params] > filename). In this mode everything is on its own line, including hash rate. You may wish to use '-r 60' to have less hash rate entries in the log. Also, every single 'difficulty = 1' candidate is logged unless actual difficulty is 1.

Version is now embedded in miner - allows user to check actual version. Pools can gather statistics about different miners and report eventual problems.

Handler methods allow someone willing to create GUI for example to receive more information from the miner.

Using the new version in Debian Squeeze, I get this error when the pool doesn't respond:
Unexpected error:
Traceback (most recent call last):
  File "/home/sensored/svn/BitcoinMiner.py", line 210, in mine
    work = self.getwork()
  File "/home/sensored/svn/BitcoinMiner.py", line 187, in getwork

    response.begin()

    version, status, reason = self._read_status()
  File "/usr/lib/python2.6/httplib.py", line 355, in _read_status
    raise BadStatusLine(line)
BadStatusLine

It does continue running, though.

In Windows 7 x64, I got those same errors right after unzipping directly over the old stuff and then double clicking my batch file. I then went to the command shell and ran it from there and everything was fine. I closed it, went back and ran the batch file again, and everything was fine.

Don't know why it started working on its own.

[realstudent]

Maybe this issue touch server side?

Today i run "poclbm_py2exe_20110204" and also see this error message.
Ok, i check update for miner - found "poclbm_py2exe_20110215".
Next i download and depack to self dir. Error continue appear .... so i wrote to forum (maybe its being helpful).

[dadittox]

Would it be possible to add a log option and flush the output to log on every line? Redirecting output to a file in windows is buffered and it's very tricky to flush the output. It would be great to see the latest log entries without waiting for output buffer to fill up.

[Grinder]

dadittox: Run the script with python -u poclbm.py

edit: guess that won't work with the exe file. Try running it from a .bat file and add
set PYTHONUNBUFFERED=1
before running the program.

Reverted back to 20110204, everything fine.

[Manto]

Just tested running the latest version (poclbm_py2exe_20110215) on a laptop with Windows 7 and NVIDIA Quadro NVS 135.  Installed the latest driver, and poclbm runs - however it's churning at mere 1khash (I get about 2khash with rpcminer-cpu with 2 threads).  Not sure if it's an issue with Quadro card or the driver - but I thought I'd report here and let everyone know my findings.

[schnak]

Ok I've updated drivers, checked for latest versions, etc. but I'm still getting this error when I try to run the batch file.

C:\Windows\system32>"D:\bitcoin\poclbm_py2exe_20110215\poclbm.exe" --user=youruser --pass=yourpw --device=0

the file is there i can see it but the script doesn't. any ideas on how to get this up and running?

Before issuing the poclbm_***.exe, switch to the right directory.

Code:

cd \
d:
cd bitcoin
cd poclbm_*****

Issue the command from here.

You don't really need a batch file to run it from Windows. Just make a shortcut on the desktop and using your example add
D:\bitcoin\poclbm_py2exe_20110215\poclbm.exe --user=youruser --pass=yourpw --device=0
to target and
D:\bitcoin\poclbm_py2exe_20110215\
to Start in.

Then you can just double click it to start.

What kind of help do you need ?

[realstudent]

In last 8 hours problem described above ("Unexpected error:") not appear.
I stay used "poclbm_py2exe_20110215".

[N12]

Awesome. I get up to 350 Mhash/s with my 5870 (overclocked to 915/1275MHz) now with the recommended settings.

I think my computer’s a bit less laggy after the update, but that could just be a placebo.

[m0mchil]

The 'Unexpected error:' doesn't affect mining at all. I just missed to handle HTTP exceptions. Will add it in next version.

@[Tycho]: For example trying to figure out why 20101126 works but later ones don't. I just don't have 5970 to test on Windows right now.
