That is if there are 4 processors, the thread's affinity being set to use all processors, can we have 4 different priorities for that thread ?

For instance, you could easily hack the P-FP plugin to support some kind of thread migration where you change the priority on every migration.

Thanks for your reply Bjorn,

That's what I figured out yesterday while researching the topic, it 
might be kind of hacky but it will do for my project.
