Energy efficiency and energy-proportional computing have become a central focus in
enterprise server architecture. As thermal and electrical constraints limit system power, and …

To increase datacenter energy efficiency, we need memory systems that keep pace with
processor efficiency gains. Currently, servers use DDR3 memory, which is designed for high …

This paper evaluates five policies for cluster-wide power management in server farms. The
policies employ various combinations of dynamic voltage scaling and node vary-on/vary-off …

Recent trends of CMOS technology scaling and wide-spread use of multicore processors
have dramatically increased the power consumption of main memory. It has been estimated …

Recent work has introduced memory system dynamic voltage and frequency scaling
(DVFS), and has suggested that balanced scaling of both CPU and the memory system is …

Reducing the energy usage of software is becoming more important in many environments,
in particular, battery-powered mobile devices, embedded systems and data centers. Recent …

Energy consumption has recently been widely recognized as a major challenge of computer
systems design. This paper explores how to support energy as a first-class operating system …

DRAM vendors have traditionally optimized the cost-per-bit metric, often making design
decisions that incur energy penalties. A prime example is the overfetch feature in DRAM …

Main memory (DRAM) consumes as much as half of the total system power in a computer
today, due to the increasing demand for memory capacity and bandwidth. There is a …

Power consumption and DRAM latencies are serious concerns in modern chip-
multiprocessor (CMP or multi-core) based compute systems. The management of the DRAM …
