WebFeb 19, 2024 · Good Afternoon, I am familiar with CUDA but not with cuFFT and would like to perform a real-to-real transform. I found information on Complex-to-Complex and Complex-to-Real (CUFFT_C2C and CUFFT_C2R). Can anyone help a cuFFT newbie on how to perform a Real-to-Real transform using cuFFT? Some simple, beginner code …

That is, In my FFTW code, I could calculate the center of the zero padding, then do some shifting to "left-align" all my data, and have trailing zeros. In CUFFT, the result from the FFT is data that looks like it is ...
WebCUFFT Performance vs. FFTW Group at University of Waterloo did some benchmarks to compare CUFFT to FFTW. They found that, in general: • CUFFT is good for larger, power-of-two sized FFT’s • CUFFT is not good for small sized FFT’s • CPUs can fit all the data in their cache • GPUs data transfer from global memory takes too long ...
