1 CPU + 1 AMD/ATI GPU - app_config.xml file?

I would like to adjust one CPU-thread for one AMD/ATI GPU app (just one WU/GPU - because of the currently/newest AMD Catalyst (v15.9.1 Beta)).

This is going just with an app_config.xml file?

This are the Einstein apps: http://einstein.phys.uwm.edu/apps.php

It looks like this are the only AMD/ATI GPU apps (Windows x64):
Binary Radio Pulsar Search (Parkes PMPS XT) - 1.52 (BRP6-opencl-ati)
Binary Radio Pulsar Search (Arecibo, GPU) - 1.39 (BRP4G-opencl-ati)

How should look it?

This would be OK?
