摘　　要：本文提出了一种解决超级计算机中系统级节能问题的方案,采用共享计算机资源实时任务执行概率和节点机安全切入和切出机制,实现了超级计算机系统中负载检测统计和预测以及节能安全决策。初步实验表明,本文提出的节能安全决策方法可以实现较多节能,其节能效果受限于具体的系统模型、开销模型和负载预测结果。This paper presents a solution to the system-level energy-saving program in supercomputer systems, which utilizes the real-time tasks executing the probability of shared computer resources and the safety mechanism to switch on and off the node machines, to achieve load detection statistics and forecasting of supercomputer systems, as well as energy-saving safety decisions. The preliminary experiments show that the proposed energy security decision-making method can achieve more energy savings, and the effect of energy saving is limited by the specific system model, overhead model and the results of load forecasting.
