I wrote a program to benchmark fftw and clfft, but I cannot get  same results with same inputs when transform complex data to real data.

Re: clFFT: complex to real, cannot get same result with fftw

Hi,

As nowadays there is not much activity in AMD Compute Libraries  forum, I'm moving this thread to OpenCL forum where you might get a quicker response from the community.

Also, you've been white-listed now.

Regards,
