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 ...

CUDA: A Quick Look and Comparison of FFT Performance on Mac

WebFFTW is the most popular FFT library. It has planty of features and it's often used as the reference point, but a number of other libraries has comparable or better performance. Intel MKL library, which is now freely redistributable, is significantly faster than FFTW. WebThe data is initialized the same way as for Accelerate. FFT Setup – CUDA uses plans, similar to FFTW. cudaPlan1D was used to generate forward and reverse plans. Only 1 plan was calculated using CUFFT_C2C as the operator type. Since the implementation is opaque, it’s not obvious what FFT type will be used. simplify 6/8 answer
