Poclbm (PyOpenCL bitcoin miner) is a python GPU bitcoin miner that uses the [[OpenCL miner|OpenCL]] framework to quickly perform the hashing computations.  Works with AMD - 4xxx and up, Nvidia - 8xxx and up, video cards.
'''poclbm''' ('''Python OpenCL bitcoin miner''') was a program that used the [[OpenCL miner|OpenCL]] framework to allow [[mining]] on a graphics card. It was the first open source GPU mining software to be produced.

If you find the desktop laggy while mining, use '-f60'. This may decrease performance slightly.

-s SLEEPTIME Sleep for the specified number of seconds between iterations (default 0). Increase this to reduce hashing performance if your temperatures are too high.

Usage Tips

ATI/AMD Radeon HD 5xxx cards (for example, HD 5770): use '-v -w128'

('-v -f10 -w128' works even better for HD5770.)

If you find the desktop laggy while mining, use '-f60'. This may decrease performance slightly.

Please update this section if you find better settings, or good settings for a card not listed here.

OpenSUSE

This works on 11.4, 12.1 and should work on other versions - just replace the "12.1" in the repo URLs with your version number. This also assumes that you are already familiar with running getting the BitCoin client running (to run the GUI version on OpenSUSE you will need `libqt4-x11` or `libqt4-x11-32bit` installed).

Add the Python devel repo:

# zypper ar -r http://download.opensuse.org/repositories/devel:/languages:/python/openSUSE_12.1/devel:languages:python.repo

and this user repo, which provides PyOpenCL (take a moment to appreciate this because if "scorot" didn't package it this would be a lot harder):

# zypper ar -r http://download.opensuse.org/repositories/home:/scorot/openSUSE_12.1/home:scorot.repo

and finally this repo, which is needed for the previous to work (replace i586 with x86_64 if you're 64-bit):

# zypper ar -r http://download.nvidia.com/opensuse/12.1/ nvidia-i586

Refresh your repos:

# zypper ref

You will asked to accept the repo keys, respond with 'a' each time.

Install PyOpenCL:

# zypper in python-opencl

Get the latest version of poclbm with git (`zypper in git-core` if you don't have git installed):

$ git clone git://github.com/m0mchil/poclbm.git

This will create a poclbm folder in your current directory. Change to it:

$ cd poclbm

And run it:

$ python poclbm.py --device=0 http://user:pass@api.example.org:8332 [add whatever other flags you use]
