interesting thing:
i have try replace a FFTGPU with a rapidmind implementation .... result ?
by standard test wu has seti crashed every time on a memory write error . it consumes a 1,5 GB (one and half gigabyte) of memory and want more .... :o
why ?
there is a function generating a twiddle arrays - this arrays are with every step greater and greater (exponencially) max size of fft on my machine (2 GB with vista) is 2 upto 20 .... :)
so i must stay on FFTGPU ...
Devaster:
Next performance issue : power spectrum calculated on GPU is (i dont now why) VERY slow ...
Rapidmind perf issue ? maybe ....
zac:
Very interesting.
i wanna know What kind of results are you seeing vs. CPU-only performance?
