Accurate power measurement is a prerequisite to energy optimization in High Performance Computing (HPC) systems. Fine temporal and spatial power profiling is also required to capture fast power fluctuations that can point to inefficiencies in applications, libraries or the operating system. Moreover, flexible deployment of powermeters is an important factor to apply power measurement in computing systems without breaking into the system circuitry or compromising the system warranty. However, it is usually a challenge to find a comprehensive solution in the market that meets all the requirements to study energy efficiency in HPC systems. In response to the various research needs, ArduPower aims at a modular internal wattmeter platform. It enables flexible deployment in computing systems, renders accurate power monitoring with a high sampling rate at component level and offers an on-the-fly power consumption analysis for given components. Its open design and low price lend it to an affordable option for fast deployment and further customization for specific needs. Our evaluations show that ArduPower is capable of delivering competitive results with commercial solutions which allows us to identify application phases within popular benchmark programs. This information can be exploited to tune for higher computational performance or energy efficiency in computing systems.
