I would like to run MB tasks only on the GPU, ie. 6.08 and AP only on the CPU.
I had no problem doing tihis, other than a bit of manual scheduling for AP, when I was using the V10 CPU_GPU team application since all MB WUs were tagged as 6.08.  Now that I have switched over to the unified installer based application I have some difficulties.  I now receive BOTH 6.08 & 6.03 tagged MB WUs.   This results in my CPUs spending most of their time running 6.03 MB tasks rather than the preferred AP tasks.  Since I keep a fairly large cache this means that I now have several hundred 6.03 tasks waiting to run, some with short due dates. 
Can I just make some changes in the appl_info.xml file so that all MB WUs will use the GPU application?  If so, will I need to empty my cache of 6.03 work first?
Thanks in advance!
