WebSep 24, 2014 · cuFFT 6.5 callback functions redirect or manipulate data as it is loaded before processing an FFT, and/or before it is stored after the FFT. This means cuFFT can transform input and output data without extra bandwidth usage above what the FFT itself uses. For our example, callbacks provide a significant performance benefit of 20% over … WebThe cuFFT library provides high performance on NVIDIA GPUs, and the cuFFTW library is a porting tool to use FFTW on NVIDIA GPUs.
