Abstract

The pyFAI package has been designed to reduce X-ray diffraction images into\npowder diffraction curves to be further processed by scientists. This\ncontribution describes how to convert an image into a radial profile using the\nNumpy package, how the process was accelerated using Cython. The algorithm was\nparallelised, needing a complete re-design to benefit from massively parallel\ndevices like graphical processing units or accelerators like the Intel Xeon Phi\nusing the PyOpenCL library.\n
