对高性能计算应用程序的功耗/能耗进行建模并分析其与应用程序性能特征的相关性可以揭示有趣的见解，并为提高功耗/能效提供有用的建议。为此，需要能够将功率/能量测量与应用程序活动同步的细粒度工具。在本文中，我们使用WattProf，这是一款新的功率监控工具，可以对计算节点中的硬件组件(例如CPU、DRAM、GPU、NIC、PCIe卡、风扇、硬盘、固态硬盘)进行高频(几千赫兹)直接功率测量。该平台支持将采集的数据流式传输到主机，将其存储在控制器上，并通过网络进行流式传输。软件实现了测量与被测应用程序的同步，从而实现了细粒度的应用程序功率分析。使用这些工具，我们对一些基准测试程序和微型应用程序进行了应用程序监控和建模。
Modeling power/energy consumption of HPC applications and analyzing its correlation with application performance characteristics can reveal interesting insights and provide useful recommendations for improving power/energy efficiency. For that purpose, fine-grained tools are needed that can synchronize power/energy measurements with application activity. In this paper we use WattProf, a new power monitoring tool that enables high frequency (multiple kilohertz) direct power measurement of hardware components in a compute node (e.g., CPU, DRAM, GPU, NIC, PCIe cards, fans, hard drives, SSD). The platform includes support for streaming the collected data to the host, storing them on the controller, and streaming via network. Software enables synchronization of the measurements with applications under test to allow fine-grained application power profiling. Using this tools, we perform application monitoring and modeling on some benchmarks and mini-applications.
