With the advent of portable and autonomous computing systems, power con sumption has emerged as a focal point in many research projects, commercial systems and DoD platforms. One current research initiative, which drew much attention to this area, is the Power Aware Computing and Communications (PAC/C) program sponsored by DARPA. Many of the chapters in this book include results from work that have been supported by the PACIC program. The performance of computer systems has been tremendously improving while the size and weight of such systems has been constantly shrinking. The capacities of batteries relative to their sizes and weights has been also improv ing but at a rate which is much slower than the rate of improvement in computer performance and the rate of shrinking in computer sizes. The relation between the power consumption of a computer system and it performance and size is a complex one which is very much dependent on the specific system and the technology used to build that system. We do not need a complex argument, however, to be convinced that energy and power, which is the rate of energy consumption, are becoming critical components in computer systems in gen eral, and portable and autonomous systems, in particular. Most of the early research on power consumption in computer systems ad dressed the issue of minimizing power in a given platform, which usually translates into minimizing energy consumption, and thus, longer battery life.

In response to worldwide demand for resource conservation and sustainability, the computing industry is investing heavily in making more energy-efficient computers. In Energy Aware Computing, the authors show that both hardware and software have a role in conserving energy. Drawing on their combined engineering experience, the authors describe how computer systems from embedded systems up through enterprise data centers can save power by making energy-efficient hardware and software decisions at the design stage.

The phenomenal increases in computer system performance in recent years have been accompanied by a commensurate increase in power and energy dissipation. The latter has directly resulted in demand for expensive packaging and cooling technology, an increase in product cost, and a decrease in product reliability in all segments of the computing market. Moreover, the higher power/energy dissipation has signi cantly reduced battery life in portable systems. While - stem designers have traditionally relied on circuit-level techniques to reduce - wer/energy, there is a growing need to address power/energy dissipation at all levels of the computer system. We are pleased to welcome you to the proceedings of the Power-Aware C- puter Systems (PACS 2000) workshop. PACS 2000 was the rst workshop in its series and its aim was to bring together experts from academia and industry to address power-/energy-awareness at all levels of computer systems. In these p- ceedings, we bring you several excellent research contributions spanning a wide spectrum of areas in power-aware systems, from application all the way to c- pilers and microarchitecture, and to power/performance estimating models and tools. We have grouped the contributions into the following speci c categories: (1) power-aware microarchitectural/circuit techniques, (2) application/compiler power optimizations, (3) exploiting opportunity for power optimization in - struction scheduling and cache memories, and (4) power/performance models and tools.

Energy and power density concerns in modern processors have led to signicant computer architecture research efforts in power-aware and temperature-aware computing. With power dissipation becoming an increasingly vexing problem, power analysis of Graphical Processing Unit (GPU) and its components has become crucial for hardware and software system design. Here, we describe our technique for a coordinated measurement approach that combines real total power measurement and per-component power estimation. To identify power consumption accurately, we introduce the Activity-based Model for GPUs (AMG), from which we identify activity factors and power for microarchitectures on GPUs that will help in analyzing power tradeoffs of one component versus another using microbenchmarks. The key challenge addressed in this thesis is real-time power consumption, which can be accurately estimated using NVIDIA's Management Library (NVML) through Pthreads. We validated our model using Kill-A-Watt power meter and the results are accurate within 10%. The resulting Performance Application Programming Interface (PAPI) NVML component offers real-time total power measurements for GPUs. This thesis also compares a single NVIDIA C2075 GPU running MAGMA (Matrix Algebra on GPU and Multicore Architectures) kernels, to a 48 core AMD Istanbul CPU running LAPACK.

This final report summarizes work done on the DARPA funded project "Compiler Optimizations for Power Aware Computing." Volume I addresses methodologies invented that can be categorized as software based approaches, hardware based approaches and combined software/hardware based approaches. One of the software based approaches, data remapping, showed a 3.1X energy*delay reduction on a realistic example. One of the hardware based approaches, frequency/voltage scaling of second-level memory, showed a 1.3X energy*delay reduction on a realistic example. A combination of data remapping and frequency/voltage scaling of second level memory showed a 2.6X reduction in energy*delay but also showed the lowest power (energy/time) of any of the approaches considered. Volume II addresses realization of the world's first Wearable Motherboard or an intelligent garment for the 21st Century. The motherboard provides an extremely versatile framework for the incorporation of sensing, monitoring, and information processing devices.
