PyCUDA lets you access `Nvidia <http://nvidia.com>`_'s `CUDA
<http://nvidia.com/cuda/>`_ parallel computation API from Python.
Several wrappers of the CUDA API already exist-so what's so special
about 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. PyCUDA knows about dependencies, too, so (for
  example) it won't detach from a context before all memory
  allocated in it is also freed.

* Convenience. Abstractions like pycuda.driver.SourceModule and
  pycuda.gpuarray.GPUArray make CUDA programming even more
  convenient than with Nvidia's C-based runtime.

* Completeness. PyCUDA puts the full power of CUDA's driver API at
  your disposal, if you wish. It also includes code for
  interoperability with OpenGL.

* Automatic Error Checking. All CUDA errors are automatically
  translated into Python exceptions.

* Speed. PyCUDA's base layer is written in C++, so all the niceties
  above are virtually free.

* Helpful `Documentation <http://documen.tician.de/pycuda>`_ and a
  `Wiki <http://wiki.tiker.net/PyCuda>`_.
