<div class="moz-cite-prefix">Hi !<br>
<br>
At first, we implemented these difference-tests to track the
development and to spot any changes in the code that could
significantly affect the results.<br>
<br>
The quite "strong" threshold values used here were adjusted based
on all the tests we performed inside the development team, based
on different computers and OS.<br>
<br>
If you take a look at your values, the maximum absolute difference
difference in a given voxel is 0.3%, which is rather
insignificant. But still, it is higher than the values we
experienced.<br>
<br>
What is your computer hardware and your OS ? What is your compiler
?<br>
<br>
Did you try to look at both images at the same time (the reference
and the challenger) to see if there is any visible pattern, line
artifact or something ?<br>
<br>
Do the other benchmarks run well ?<br>
<br>
Cheers<br>
Simon<br>
