Hi all,
i’m wondering if it is possible to use 2d structures allocated with cudamallocpitch that are properly sized with a pitch in cufft calls.
Does CUFFT manages pitches of input and output data structures? If so, how does it do it, as no information about the pitches is requirend in the cufft call?
For instance, I have:
cudaMallocPitch((void**)&u_fft, &pitch_u_fft, cN2cuSizeC,c*N1);
…
cufftResult result = cufftPlan2d(&plan, cN1,cN2, CUFFT_C2C);
cufftExecC2C(plan, u_buffer, u_fft, CUFFT_FORWARD);
Can I use cufft with the 2D structure without providing the pitch_u_fft? If so, It sounds strange.
Please help me to understand if i can do it.
Thank you.
