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 (). WebUnified memory attempts to optimize memory performance by migrating data to the device that needs it, at the same time hiding the migration details from the program. ... In the …
