PyOpenCL lets you access GPUs and other massively parallel compute
devices from Python. It tries to offer computing goodness in the
spirit of its sister project `PyCUDA <http://mathema.tician.de/software/pycuda>`_:
* Object cleanup tied to lifetime of objects. This idiom, often
called
`RAII <http://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization>`_
in C++, makes it much easier to write correct, leak- and
crash-free code.
* Completeness. PyOpenCL puts the full power of OpenCL's API at
your disposal, if you wish. Every obscure `get_info()` query and
all CL calls are accessible.
* Automatic Error Checking. All CL errors are automatically
translated into Python exceptions.
* Speed. PyOpenCL's base layer is written in C++, so all the niceties
above are virtually free.
* Helpful and complete `Documentation <http://documen.tician.de/pyopencl>`_
as well as a `Wiki <http://wiki.tiker.net/PyOpenCL>`_.
* Liberal license. PyOpenCL is open-source under the
`MIT license <http://en.wikipedia.org/wiki/MIT_License>`_
and free for commercial, academic, and private use.
* Broad support. PyOpenCL was tested and works with Apple's, AMD's, and Nvidia's
CL implementations.
What you'll need:
* gcc/g++ at or newer than version 4.8.2 and binutils at or newer than 2.23.52.0.1-10.
* `numpy <http://numpy.org>`_,
* an OpenCL implementation. (See this `howto <http://wiki.tiker.net/OpenCLHowTo>`_ for how to get one.)
* `Python package index <http://pypi.python.org/pypi/pyopencl>`_ (download releases)
