Abstract:
Power and energy are first-class operating concerns for data centers, emerging supercomputers, and future exascale machines. The power and energy measurement capabilities in emerging systems is critical to understand and optimize power usage according to application characteristics. In this work, we describe our evaluation of the power monitoring capabilities of the Zaius Power9 server. We highlight existing limitations of this system and report on the available power domains, measurement granularity, and sampling rate. We provide empirical power profiles that stress the memory system and the compute capabilities. Furthermore, we demonstrate high-level insights of a scientific proxy-application through its power consumption. Our goal is to provide an empirical study for the benefit of developers and researchers planning on utilizing the power capabilities of this state-of-the-art architecture.
