<p>Gilles,</p>
<p>My system has a 6 core CPU with 16 GB of main memory; OS is
openSUSE Leap 42.3, I am running DK 5.7.0-178.7 as provided by
SUSE distribution.</p>
<p>I am encountering a problem with multi core processing in BQM
when converting NIKON raw files and using all 6 cores; BQM is
using the following workflow:</p>
<p>Color Auto-correction</p>
<p>Sharpen Image</p>
<p>Color Effects</p>
<p>Convert to JPEG</p>
<p>This works fine with just ONE image in the run-Queue and "Work on
all processor cores" enabled. With more than one image in the
queue I only get a pattern of fine lines in RGB colors in the
resulting jpegs . Disabling "Work on all processor cores" I get
correct results for all pictures, but clearly at the prize of
loosing all the possible speedup of the 6 cores. <br>
</p>
<p>With all cores enabled I can see that every core is allocating
its one memory, and there is definitely enough memory on my
system.</p>
<p>Could it be, that for some reason the memory gets mixed up among
the six running jobs? Or am I doing something wrong?</p>
<p>Best regards,</p>
<p>Robert Zeller<br>
