Welcome to the proceedings of the 3rd Power-Aware Computer Systems (PACS 2003) Workshop held in conjunction with the 36th Annual International Symposium on Microarchitecture (MICRO-36). The increase in power and - ergy dissipation in computer systems has begun to limit performance and has also resulted in higher cost and lower reliability. The increase also implies - ducedbatterylifeinportablesystems.Becauseofthemagnitudeoftheproblem, alllevelsofcomputersystems, includingcircuits, architectures, andsoftware, are being employed to address power and energy issues.
