I am running 2 cores right now, plus the GPU. Will the appinfo below run 2 at once on the GPU??

And, would it be wise to do the same with AP??

Will the appinfo below run 2 at once on the GPU??

No.
<count>0.5</count> is OK but you forget -instances_per_device


<cmdline>-period_iterations_num 20 -instances_per_device 2</cmdline>
<coproc>
<type>ATI</type>
<count>0.5</count>


And, would it be wise to do the same with AP??

Why not? (if you want 2 tasks on the GPU it is the AP which benefit more due to high-blanked AP tasks do not load GPU much)
