Intro ¶

I like the BitCoin idea, mostly for the GPU computation part and to see if the idea actually holds. For my statistics look at ​Eligius stats for 1AdxXkR3aB6xwPU6XwPZMZhu2v9avFuFoJ

Install and Run ¶

To get it running under Ubuntu 10.10 with NVIDIA CUDA 3.2 tools installed, requires some tricks as python-pyopencl requires a whole bunch of non-compatibele NVIDIA stuff to be installed.

$ sudo apt-get install blt dkms libboost-python1.42.0 python-dateutil python-decorator python-matplotlib python-matplotlib-data git-core libboost-python-dev $ mkdir ~/src $ cd ~/src $ git clone ​http://git.tiker.net/trees/pyopencl.git $ cd pyopencl $ ./configure.py

$ cat <<EOF > siteconf.py
BOOST_INC_DIR = []
BOOST_LIB_DIR = []
BOOST_COMPILER = 'gcc43'
BOOST_PYTHON_LIBNAME = ['boost_python-py26']
USE_SHIPPED_BOOST = False
CL_TRACE = False
CL_ENABLE_GL = False
CL_ENABLE_DEVICE_FISSION = False
CL_INC_DIR = ['/usr/local/cuda/include']
CL_LIB_DIR = ['/usr/local/cuda/lib64']
CL_LIBNAME = ['OpenCL']
CXXFLAGS = []
LDFLAGS = []
EOF

$ make $ sudo make install

Now download and run the miner. I run mine against the ​Eligius Grid. Replace 1AdxXkR3aB6xwPU6XwPZMZhu2v9avFuFoJ with your own BitCoin Address, else thanks for the donation!

$ cd ~/src $ git clone ​https://github.com/m0mchil/poclbm $ cd poclbm $ python poclbm.py --device=0 --pass=x --host=mining.eligius.st --port=8337 --user=1AdxXkR3aB6xwPU6XwPZMZhu2v9avFuFoJ --verbose

For daily usage you can run it as a daemon with verbose logging if wanted:

$ python poclbm.py --device=0 --pass=x --host=mining.eligius.st --port=8337 --user=1AdxXkR3aB6xwPU6XwPZMZhu2v9avFuFoJ --verbose >> bitcoin-mining.log &

If you have multiple GPUs in your system, make sure to fire up multiple installed with different --device= ID.
