Monitoring Power Consumption with the Intelligent Platform Management Interface

“NWPerf is software that can measure and collect a wide range of performance data about an application or set of applications that run on a cluster. With minimal impact on performance, NWPerf can gather historical information that then can be used in a visualization package. The data collected includes the power consumption using the Intelligent Platform Management Interface (IPMI) for the Intel Xeon processor and the libmicmgmt API for the Intel Xeon Phi coprocessor. Once the data is collected, and using some data extraction mechanisms, it is possible to examine the power used across the cluster, while the application is running.”

Application Performance & Power Consumption on Intel Xeon Phi

“While new technology will be developed that reduces the power per operation needed, in today’s environments it is important to understand how an application affects power usage. For modern applications that have been optimized to take advantage of both the Intel Xeon CPU and the Intel Xeon Phi coprocessor, the hardware mentioned does include various power states, which can minimize the power consumption when idle.”
