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. –

WebcuFFT provides FFT callbacks for merging pre- and/or post- processing kernels with the FFT routines so as to reduce the access to global memory. This capability is supported experimentally by CuPy. Users need to supply custom load and/or store kernels as strings, and set up a context manager via set_cufft_callbacks ().
