WebMar 17, 2024 · The data copy is done using cuFFT's API, so please refer to the multi-GPU example in cuFFT documentation linked in my post. What's done in CuPy's low-level API is an almost 1-to-1 translation of that. It is interesting to explore if managed (unified) memory can be of any help, but I didn't pay much attention during development. –
