I am working on a simulation whose bottleneck is lots of FFT-based convolutions performed on the GPU. I wanted to see how FFT’s from CUDA.jl would compare with one of bigger Python GPU libraries CuPy. I was surprised to see that CUDA.jl FFT’s were slower than CuPy for moderately sized …

Webcupy.fft.fft(a, n=None, axis=-1, norm=None) [source] #. Compute the one-dimensional FFT. Parameters. a ( cupy.ndarray) – Array to be transform. n ( None or int) – Length of the transformed axis of the output. If n is not given, the length of the input along the axis specified by axis is used. axis ( int) – Axis over which to compute the FFT. WebJun 2, 2024 · I want to use CUDA.jl instead of CUDA C/C++ on Jetson nano (Single-board computer with GPU), but I am puzzled by the inexplicable memory usage when executing CUFFT.ifft(). 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 … cyp in vitro 代謝試験
