WebCUFFT Performance vs. FFTW CUFFT starts to perform better than FFTW around data sizes of 8192 elements. Though I don’t show it here, nflops for CUFFT do decrease for … WebFeb 8, 2024 · Those CUDA 11.6/11.7 CUFFT libraries may not work correctly with 4090. That was the reason for my comment. NVIDIA recommends CUDA 11.8 minimum for use with RTX 40 series GPUs, and its often the case that it takes a while for DL framework “providers” to catch up with these needs and provide a new version that is linked against …
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.
