I compute WUs on WIN10 with CPU i7-5820k and two NVIDIA GPUs.
I excluded one GPU for the project in cc_config.xml.
The WU should use 0.2 CPUs + 1 NVIDIA GPU.
But it runs with 2 CPUs + GPU.

Example:
Program: dnetc518-win32-x86-cuda31.exe

init_data.xml:
<wu_name>dnetc_r72_1479654546_12_768</wu_name>
…
<gpu_type>NVIDIA</gpu_type>
<gpu_device_num>0</gpu_device_num>
<gpu_opencl_dev_index>0</gpu_opencl_dev_index>
<gpu_usage>1.000000</gpu_usage>
<ncpus>0.200000</ncpus>

Why does the job use two full CPUs (16% usage)?
