Energy-Efficient Cluster Computing via Accurate Workload Characterization
This paper presents an eco-friendly daemon that reduces power and energy consumption while better maintaining high performance via an accurate workload characterization that infers "processor stall cycles due to off-chip activities." The eco-friendly daemon is an interval-based, run-time algorithm that uses the workload characterization to dynamically adjust a processor's frequency and voltage to reduce power and energy consumption with little impact on application performance. Using the NAS Parallel Benchmarks as our workload, we then evaluate our eco-friendly daemon on a cluster computer. The results indicate that our workload characterization allows the power-aware daemon to more tightly control performance (5% loss instead of 11%) while delivering substantial energy savings (11% instead of 8%).
