Query: PyFAI: a Python library for high performance azimuthal integration on
  GPU   The pyFAI package has been designed to reduce X-ray diffraction images into
powder diffraction curves to be further processed by scientists. This
contribution describes how to convert an image into a radial profile using the
Numpy package, how the process was accelerated using Cython. The algorithm was
parallelised, needing a complete re-design to benefit from massively parallel
devices like graphical processing units or accelerators like the Intel Xeon Phi
using the PyOpenCL library.
