WebJan 27, 2024 · Today, NVIDIA announces the release of cuFFTMp for Early Access (EA). cuFFTMp is a multi-node, multi-process extension to cuFFT that enables scientists and engineers to solve challenging problems on exascale platforms.. FFTs (Fast Fourier Transforms) are widely used in a variety of fields, ranging from molecular dynamics, … WebCUFFT Performance CUFFT seems to be a sort of "first pass" implementation. It doesn’t appear to fully exploit the strengths of mature FFT algorithms or the hardware of the GPU. For example, "Many FFT algorithms for real data exploit the conjugate symmetry property to reduce computation and memory cost by roughly half.
