WebNote that CuFFT semantics for inverse FFT only flip the sign of the transform, but it is not a true inverse. Similarly, the real to complex / complex to real variants also follow NumPy semantics and behavior. In the 1D case, this means that for an input of size N, it returns an output of size N//2+1 (it omits redundant entries, see the Numpy docs) WebJun 2, 2024 · I have confirmed that the memory usage of the Julia process increases by about 800 MB only when CUFFT.ifft() is executed on multiple environments, including …
