## Intro

I like the [BitCoin](/notes/BitCoin/) idea, mostly for the GPU computation part and to see if the idea actually holds.

## 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.

```sh
$ 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
```

```sh
$ make
$ sudo make install
```
Now download and run the miner. I run mine against the [Eligius Grid](http://eligius.st/notes/index.php/Getting_Started). Replace `1PZmETDRFw4Sd6AXkaqKbGos5ZjHZgxxM4` with your own [BitCoin](/notes/BitCoin/) Address, else thanks for the donation\!

```sh
$ 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=1PZmETDRFw4Sd6AXkaqKbGos5ZjHZgxxM4 --verbose
```
For daily usage you can run it as a daemon with verbose logging if wanted:

```sh
$ python poclbm.py --device=0 --pass=x --host=mining.eligius.st --port=8337 --user=1PZmETDRFw4Sd6AXkaqKbGos5ZjHZgxxM4 --verbose >> bitcoin-mining.log &
```
If you have multiple GPUs in your system, make sure to fire up multiple installed with different `--device=` ID.
