Those would be running completely independently - I mean no interaction 
between the GPUs like work handover, buffer sharing and that? If so my 
gut feeling is that the direction needs to be carefully considered. Test 
runner could do that just as well for probably much less complication. 
But that's just my opinion, so FWIW.
