WebJun 1, 2014 · Power of 2 is not necessary for all FFT implementations, and it seems that CUFFT can cope with non power of 2 for larger FFT sizes anyway, where it uses multiples of 512 instead. For convolution you can't usually make the FFT size a power of 2, because the dimensions needs to be image_dimension + kernel_dimension - 1, hence the need for … WebMay 18, 2024 · Robert_Crovella May 17, 2024, 2:13am 5. not cufft plan, but cufft execution, yes, it should be possible. cufft has the ability to set streams.
