WebAug 31, 2024 · 1 I am new to FFTW library. I have successfully implemented 1D and 2D fft using FFTW library. I converted my 2D fft code into multithreaded 2D fft. But the results were completely opposite. Multithreaded 2D FFT code is taking longer time to run than serialized 2D FFT code. I am missing something somewhere.
