Sometimes I get far to many results (e.g. 10000 files with 300000 results for identical files).
It looks likes that for a certain time period file comparison with "precise" returns very quickly 100% instead of really comparing the files.
Maybe it is related to CUDA?

When you enabled OpenCL in the corresponding options tap you better start a benchmark run first. I got an "calculation error" (AMD/ATI 5570) and most comparison results gave false 100% indication.
Only way out in this case: Switch off OpenCL (CUDA).

Yes, in beta version please use "benchmark" button to check correct calculation, we add warning before enabling OpenCL without checking.
And use latest beta version we corrected behaviour with old/low-end ATI videocards.

well I was using a MSI card with Nvidia GTX460, the same card that was used for your tutorial...
I get no error and Benchmark is fine...
Also an indicator for developers: the result returns much faster than the normal calculation result...

in the log I get:
CIppsVector::insert:244 failed [false]
quite often
maybe it is related to it?

How much RAM memory do you have ? And how much files do you scan ?
This issue related to "no memory" problem.
