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 ... WebApr 11, 2014 · Cufft_R2C and Cufft_C2R are inaccurate. My testing codes for ifft (C2R) are attached. cudaMemcpy (x,d_x,sizeof (float) NO_x1 NO_x2,cudaMemcpyDeviceToHost); here is a small code I made (based on yours, so if some stuffs look similar it’s normal ;) ). It’s a R2C transform, followed by a C2R one.
