2D FFT with CUDA FFT Library

Accelerated Computing CUDA CUDA Programming and Performance

Hi @ all

I use Cuda 4.0 Library with a Windows XP (32Bit) System.

Can I use the CUDA 2D FFT with “real to complex” parameter or can I only use this function with “complex to complex” parameter?

Yes, CUFFT supports real to complex transforms.

I get an error with 2D FFT (real to complex). But if I use 1D FFT (real to complex) the FFT works fine

Hello,

I have a program which performs an iterative algorithm to solve some partial differential equations. My programs performs tens of thousands of transforms both real to complex and complex to real. So it works. What are the errors? Or post the code.
