Included in NVIDIA CUDA Toolkit, these libraries are designed to efficiently perform FFT on NVIDIA GPU in linear–logarithmic time. How is this possible? Is this what to expect from cufft or is there any way to speed up cufft? VkFFT is an efficient GPU-accelerated multidimensional Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL/Level Zero/Metal projects. If the "heavy lifting" in your code is in the FFT operations, and the FFT operations are of reasonably large size, then just calling the cufft library routines as indicated should give you good speedup and approximately fully utilize the machine. batching the array will improve speed? is it like dividing the FFT in small DFTs and computes the whole FFT? i don’t quite understand the use of the batch, and didn’t find explicit documentation on it… i think it might be two things, either: divide one FFT calculation in parallel DFTs to speed up the process calculate one FFT x times When comparing the stock 1950X score to the 3.
