Web1 day ago · The way I see it, I would need to reshape my input image to a size of [8,4,8,4], and then permute the middle two indices for a final shape of [8,8,4*4], and then I could run the standard 2D batched FFT. I could do this with a custom CUDA kernel that would involve copy-pasting, but I was wondering if cuFFT already has this functionality (maybe ... 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 …
