The bufferkdtree package has been tested under various Linux-based systems such as Ubuntu and OpenSUSE and requires Python 2.6 or 2.7. Below, some installation instructions will be given for Linux-based systems; similar steps have to be conducted on other systems.
On Ubuntu 12.04, for instance, the following command installs all dependencies (except for OpenCL):
$ sudo apt-get install python2.7 swig build-essential python-numpy
On an OpenSUSE system, the corresponding commands are:
$ sudo zypper install python python-devel swig
The implementation is based on the efficient use of implicit hardware caches. Thus, to obtain good speed-ups, the GPU at hand has to support this feature! Current architectures such as Nvidia’s Kepler architecture exhibit such caches, see, e.g., the Kepler GK110 Whitepaper.
OpenCL needs to be installed correctly. Make sure that the OpenCL header files are available, for example by setting the C_INCLUDE_PATH environment variable in the .bashrc file on Linux systems. For instance, in case CUDA is installed with header files being located in
/usr/local/cuda/include, then the following command should update the environment variable:

$ sudo pip install bufferkdtree
To install the package from the sources, first get the current version via
$ git clone https://github.com/gieseke/bufferkdtree.git
Subsequently, install the package locally via:
$ cd bufferkdtree $ python setup.py install --user
or, globally for all users, via:
$ sudo python setup.py build $ sudo python setup.py install
Virtualenv & Pip¶
We recommend to install the package via virtualenv and pip. On Ubuntu 12.04, for instance, the following commands can be used to install virtualenv and pip:
$ sudo apt-get install python-virtualenv python-pip
Afterwards, create a new virtual environment and install the Numpy package:
$ mkdir ~/.virtualenvs $ cd ~/.virtualenvs $ virtualenv bufferkdtree $ source bufferkdtree/bin/activate $ pip install numpy==1.6.1
Given the activated virtual environment, follow the instructions above to install the bufferkdtree package.
