Comparison of several FFT libraries in C/C++
Philippe Gambron, Sue Thorne · Science and Technology Facilities Council · 2020
We compare the performance of several libraries computing FFTs that can be called from C or C++ code. In this work, we consider FFTW, MKL, GSL and FFT- PACK. A benchmarking method was developed in collaboration with CCP-PETMR, which we generalised to ensure that this work applied to a wider range of the UK's Computational Collaborative Projects and High-End Computing Consortia.
