An Evaluation Infrastructure for Power and Energy Optimizations
Abstract
The goal of this project is to develop an evaluation infrastructure
for power and energy optimizations that consists of a combination of
physical measurements and performance modeling. Physical measurements
will include current and voltage measurements, as well as temperature
measurements. Performance modeling will include models for the CPU,
memory subsystems, controllers, communication modules, and I/O devices
such as the disk and screen. This technology is crucial to be able to
understand and assess the benefits of a proposed optimization for the entire
target system, subsets of system components, or single system components.
Currently, no such research enabling infrastructure is available. The lack
of such an infrastructure has greatly inhibited research into new power
and energy management strategies, in particular in the operating systems
and compiler research communities where validation experiments typically
require physical measurements on existing target systems.
Funded as a pilot project by Rutgers's Information Sciences and Technology
Council for one year beginning in May 2003.
