“…Due to their small form factor, SBC devices are inherently energy efficient, it is worth investigating if a cluster comprising of SBCs as nodes provides a better performance ratio in terms of power consumption and dollar cost. Although we did not measure the FLOPs per watt efficiency of either of our clusters, we notice wide inconsistencies in energy consumption results reported in the literature [4][5][6][7][8]38] for similar devices. This is due to the power measurement instruments varying results and inconsistencies in the design of power supplies.…”

“…At the same time, environmental concerns faced by many large-scale cloud computing infrastructure operators, have prompted the need for more energy efficient operation of infrastructure. Recent considerations in energy efficiency [4][5][6][7][8][9][10] has improved the understanding and need for more energy efficient Cloud computing technologies.…”

“…Energy measurements should be used for algorithm engineering [1], and there is a strong need for tool support, such as PowerPack [8]. RAPL is being studied as a measurement method for energy consumption [6,9,10,13,17], and energy measurements that are based on RAPL are being developed for specific scenarios [11,15,18,19] and used to evaluate algorithms [7]. CPU Energy Meter makes energy measurement conveniently accessible to verification researchers.…”

“…It is nowadays evident that the tradeoff between performance and energy consumption is a key challenge for future large-scale green HPC infrastructures [1]. Such infrastructures include a large variety of sensors for measuring architectural and physical run-time parameters.…”

“…Both architectural and physical parameters have been historically used to understand applications performance and bottlenecks, as well as to monitor the status of the infrastructure by system administrators. With a view to increasing the total energy efficiency, there is an increasing demand for correlating applications and architectural events, measured from the processing elements, with physical parameters taken at the node level [1].…”
