Evaluation of DRAM Power Consumption in Server Platforms
Low power computing issues become bigger and bigger for cost saving and environment. In case of CPU, DVFS technique can save runtime energy consumption. Fortunately, DRAM is usable at various frequency levels and we might use it for low power computing. Through the experiment, we find strong relationship between memory usage pattern of benchmark and power consumption before modeling and scheduling.
