1.7 Organization
This dissertation is organized as follows:
Chapter 2 describes the methodology for measuring power and performance
events within a range of system types and subsystems ranging from CPUs to hard drives.
Techniques are provided for isolating and measuring dynamic and static power within
actual computing systems.
Chapter 3 presents an analysis of processor performance events that correlate to
power consumption. These findings direct the construction of a simple, speculation-
aware power model based on a small number of performance events. A formal
methodology for developing performance counter power models is presented.
Chapter 4 provides a broad analysis of subsystem-level power consumption across
a wide range of workloads including scientific computing, commercial transaction
processing, desktop productivity, content creation and consumption. Power is considered
in relative terms comparing across each subsystem. To inform power management
decisions, power phase behavior is considered in terms of duration and amplitude.
Chapter 5 presents an extensive number of system power models based upon
processor performance counters. The motivation behind the composition of each model
is provided. Accuracy statistics and measure versus modeled time-domain comparisons
are given.
