Hello,
I need the input data to be conserved. There are two solutions for this: Either make a copy of the input data in the device memory and use the copy as input for a in-place fft or directly use the out-of-place fft.
All transformations are large complex to complex.
Which option will be faster?
Another question: Can I change the placeness with clAmdFftSetResultLocation after baking the plan?
