Tool for generating optimal setting of the cuFFT library.
This tool is able to:
- benchmark some transformation.
- run fast heuristics which will recommend faster settings, using either padding or cropping.
- autotune the heuristics proposals and thus obtainign the best setting possible
pending
Simply run make in the root directory. Make sure that you have NVCC and Cuda libraries in the PATH

Internal heuristics is based on Cuda v.8, so it might not be very accurate for other versions.
