A Validation of DRAM RAPL Power Measurements
Spencer Desrochers, Chad Paradis, Vincent M. Weaver · 2016
Recent Intel processors support the Running Average Power Level (RAPL) interface, which among other things provides estimated energy measurements for the CPUs, integrated GPU, and DRAM. These measurements are easily accessible by the user, and can be gathered by a wide variety of tools, including the Linux perf_event interface. This allows unprecedented easy access to energy information when designing and optimizing energy-aware code.
