            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.
