A newbie question on Occupancy Calculator

Accelerated Computing CUDA CUDA Programming and Performance

Hello all,

anyone could explain me why in CUDA_Occupancy_calculator, value B34 (MyRegsPerBlock) results from rounding (MyWarpsPerBlock2) to multiples of 4
and then multiplication to 16MyRegCount?
Why just not MyThreadCount * MyRegCount?

Davide.
