Is it possible to take advantage of the hermitean properties of the Fourier transform with CUFFT? If I remember correctly, if the signal to be transformed is real valued, half of the signal can be put in the real part and half in the imaginary part, to speedup the FFT a factor 2, is that possible with CUFFT? Does the real to complex (R2C) setting take advantage of this?
I would guess no, because it said repeatedly in the CUFFT manual that I read that there is no performance boost in using any of the real-valued transforms.
