I run 1.42 (cudaPPSsieve) on my 3 Titans, but the app takes all my CPU cycles of 8 Cores of the XEON, it shows CPU usage=100%.
I let run 4 at once per GPU, so I got 95-98% usage of the GPU's.
The high usage of CPU=100% is not normal. With the old app 1.39 cudaPPSsieve I had never seen such values.
Please can you take a look at my machine V8-Xeon
What must I do to reduce CPU-Usage to max 20%

my app_config looks like this:
here you see usage, temps and all other important values
thanks _heinz
