Todo List

2022

  • [Lei, Nov 11, 2022] The total GPU memory usage is only optimized for KerPolyOrder = 2 & BGPolyOrder = 2, I will extend the optimization to other cases ASAP! In fact, I believe there is ample space for reducing the total GPU usage and I will explore it. [FINISHED]

  • [Lei, Nov 11, 2022] I will allows users to disable the hough detection for preprocessing when there are too few sources in the field in the next version sfft v1.3.5.

  • [Lei, Nov 9, 2022] Add a verbose argument for sfft so that users can get more clean printed messages. [FINISHED]

  • [Lei, Nov 9, 2022] Test if we can use sep to replace SExtractor in preprocessing to make sfft more Pythonic.

  • [Lei, July 6, 2022] Incorporate the separate functions for spline form sfft into the unified sfft functions. Note that only Numpy backend is currently available and the spline form is very memory-consuming. [FINISHED]

  • [Lei, May 24, 2022] Write a detailed documentation for sfft! [FINISHED]

  • [Lei, May 24, 2022] We notice that SExtractor may have been called to perform astrometric calibration before image subtraction. It is definitely not wise to run SExtractor again in sfft, I need to develop a module which allows users to feed SExtractor products as inputs of sfft, which will significantly reduce the preprocessing time in sfft.

  • [Lei, May 24, 2022] The multiprocessing mode is expected to accomondate multiple GPU devices, however, the function has not tested on such a multi-GPUs platform. [FINISHED]

  • [Lei, May 20, 2022] Add a function for optimizing sfft on a given computing platform with multiple CPU threading and one/multiple GPU card(s). This would be very useful to reduce the overall time cost when users have a large set of image-pairs to be processed simultaneously. [FINISHED]
