在过去几年中，能源消耗已成为高性能计算的主要主题。我们提出了一种有效管理电力群集群的功率状态的方法，包括处理器，网卡和磁盘。为了从这些状态的较低功耗中获利，我们遵循将应用程序知识（例如未来硬件使用）转移到守护程序的方法，该方法有效地管理了每个群集节点的硬件设备状态。引入了测量环境后，我们评估了AMD和Intel计算节点的一般电力节省潜力。两个示例的高性能应用是初始仪器的展示案，这导致能量到解决方案在4％至8％之间的降低，而略有增加时间的时间。
Energy consumption has become a major topic in high performance computing in the last years. We present an approach to efficiently manage the power states of an power-aware cluster, including the processor, the network cards and the disks. To profit from the lower power consumption of these states we followed the approach to transfer application knowledge (e.g. future hardware use) to a daemon which efficiently manages the hardware device states per cluster node. After introducing our measurement environment we evaluated the general power saving potential of our AMD and Intel computing nodes. Two example high performance applications are showcases for an initial instrumentation which results in a reduction of the Energy-to-Solution between 4 and 8% with slight increases of the Time-to-Solution.
