    What is the occupancy value in detail?

      Hello everybody,

       

      i got a AMD 7970 and noticed for the occupancy value a hardware limitation for 40 wavefronts. My question is, are the 40 wavefronts per compute unit? Otherwise i can't image how the 40 wavefronts are distributed to 32 CUs. Also i thought 40 wavefronts is a really small amount for the whole GPU to be able to hide the latencies in a good way.

       

      best,
