Compute units on emulator

Hi, I would like to say if the emulator considers the use of multiple compute units. I do not have a physical board for working, so if I had more than one compute unit, how does the emulator work?...

I think it should. However, the vector_add example only uses one work-group and hence (no get_local_id() in the kernel), there is no point in using num_compute_units. I guess that is the reason why the number of CUs does not increase in the report. Though, for some reason, the area utilization goes up when you increase the number of CUs, which means the compiler is changing the circuit.
