In this paper, we design, implement, and evaluate a traffic-aware and power-efficient multicore server system by translating incoming traffic rate to appropriate system operating level, which is then translated to optimal per-core frequency configuration. According to the varying traffic rate, the system can adjust the number of active cores and per-core frequency “on-the-fly” via the use of per-core DVFS, power gating, and power migration techniques based on our new power model which considers both dynamic and static power consumption of all cores. Results on an AMD machine with two Quad-Core Opteron 2350 processors for six real network applications chosen from NetBench [19] show that our scheme reduces power consumption by an average of 41.0% compared to running with full capacity without any reduction in throughput. It also consumes less power than three other approaches, chip-wide DVFS [22], power gating [17], and chip-wide DVFS + power gating [15], by 35.2%, 24.3%, and 10.5% respectively. |
