—Low power is an important design requirement for HPC systems nowadays. Dynamic voltage and frequency scaling (DVFS) has become the commonly used and efficient technology to achieve a trade-off between power consumption and system performance. However, most of the prior work using DVFS did not take into account the latency of voltage/frequency scaling,(More)
—The rising core count per processor is pushing chip complexity to a level that hardware-based cache coherency protocols become too hard and costly to scale someday. We need new designs of many-core hardware and software other than traditional technologies to keep up with the ever-increasing scalability demands. A cluster-on-chip architecture, as(More)
Energy efficiency is quickly becoming a first-class design constraint in high-performance computing (HPC). We need more efficient power management solutions to save energy costs and carbon footprint of HPC systems. Dynamic voltage and frequency scaling (DVFS) is a commonly used power management technique for making a trade-off between power consumption and(More)
