WebIndeed, if you try increasing M, then the cuFFT will start trying to compute new column-wise FFTs starting from the second row. The only solution to this problem is an iterative call to cufftExecC2C to cover all the Q slices. … WebApr 27, 2016 · cuFFT performs un-normalized FFTs; that is, performing a forward FFT on an input data set followed by an inverse FFT on the resulting set yields data that is equal to the input, scaled by the number of elements. Scaling either transform by the reciprocal of the size of the data set is left for the user to perform as seen fit.
10 Ways CUDA 6.5 Improves Performance and Productivity
WebIn High-Performance Computing, the ability to write customized code enables users to target better performance. In the case of cuFFTDx, the potential for performance improvement of existing FFT applications is high, but it greatly depends on how the library is used. Taking the regular cuFFT library as baseline, the performance may be up to one ...

In my hands MKL is ~50% faster. Maybe I didn't squeeze all the performance from FFTW.) FFTW is not the fastest one anymore, but it still has many advantages and it is the reference point for other libraries. MKL (Intel Math Kernel Library) FFT is significantly faster.
