Measuring and Managing Power Consumption


This presentation will include an overview of the power, thermal, and performance data that can be collected from OpenPOWER servers via various methods, including a newly open sourced profiling tool called AMESTER.   The power/performance knobs, such as processor frequency, that are under the control of the On Chip Controller (OCC) will be described and the overall OCC power management functions will be highlighted.
