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 ... WebCUFFT default behavior is to allocate the work area at plan generation time. If cufftSetAutoAllocation() has been called with autoAllocate set to "false" prior to one of the cufftMakePlan*() calls, CUFFT does not allocate the work area. This is the preferred sequence for callers wishing to manage work area allocation.

WebMar 29, 2024 · I tested the performance of float cufft and FP 16 CUFFT on Quadro Gp100. But the result shows that time consumption of float cufft is a little lower than FP16 CUFFT. Since the computation capability of Gp100 is 6.0, the result makes me really confused.
