CS290N Extra-Performance Computer Architecture Prof. Fred Chong FQ 2006 Problem Set 9 (Scheduling for energy - Maria del Mar Alvarez Rohena) 1) How does Odyssey support application adaptation? 2) What is the average energy savings obtained from fidelity reduction in the Odyssey applications? When is the fidelity reduction not beneficial? Why? 3) Why does the idle state dominate energy usage? What is their solution for this problem? 4) What are the main goals of the "goal-directed" energy adaptation? What must Odyssey do to achieve this? Is it successful?
