能耗并行加速比:高性能计算系统综合性能的有效度量
Power Parallel Speedup: An Effective Metric for Evaluating the Comprehensive Performance of High-Performance Computing Systems
摘要
Abstract
As parallel systems scale up, the energy consumption of high performance computing systems drastically in-creases. The use of high power and energy leads to many problems, such as low reliability, bad stability and so on. In this case, the energy consumption problem draws unprecedented attention. Thus it is necessary to take into account the energy consumption while pursuing high computing performance in system design and research. This brings a new challenge for building a high performance computing system metric model. The measure index for the performance of the large-scale sys-tem demands a shift from "high performance" to "high productivity". Then, this paper uses speedup, synthetically meas-ures the computing performance and energy consumption in view of system scalability, and proposes a power parallel speedup for evaluating the comprehensive performance of high-performance computing systems. The model can measure the pro-ductivity of parallel systems and guide system design and application research. Finally, we validate the model of power par-allel speedup through analysis and simulation.关键词
