WebApr 24, 2024 · The cuFFT API is modeled after FFTW, which is one of the most popular and efficient CPU-based FFT libraries. cuFFT provides a simple configuration mechanism called a plan that uses internal building blocks to optimize the transform for the given configuration and the particular GPU hardware selected. WebThe cuFFT library provides a simple interface for computing FFTs on an NVIDIA GPU, which allows users to quickly leverage the GPU’s floating …

I took this code as a starting point: [url] cuda - 1D batched FFTs of real arrays - Stack Overflow. To minimize the number of memory transfers I calculate the maximum batch size that will fit on my GPU based on my memory size.
