A growing number of supercomputers are being built using processors with low-power embedded ancestry, rather than traditional high-performance cores. In order to evaluate this approach we investigate the energy and performance tradeoffs found with ten different 32-bit ARM development boards while running the HPL Linpack and STREAM benchmarks. Based on(More)
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(More)
