paper investigates the power profiles of irregular programs running on a K20 compute GPU and contrasts them with the profiles of regular programs. The paper further studies the effects on the power profile when changing the GPU's core and memory frequencies, using alternate implementations of the same algorithm, and varying the program input. Our results show that the power behavior of irregular applications often cannot be accurately captured by a single average. Rather, the entire profile, i… CONTINUE READING
