Energy proportionality in near-threshold computing servers ...
Cloud Computing aims to efficiently tackle the increasing demand of computing resources, and its popularity has led to a dramatic increase in the number of computing servers and data centers worldwide. However, as effect of post-Dennard scaling, computing servers have become power-limited, and new system-level approaches must be used to improve their energy efficiency.
Blink: managing server clusters on intermittent power: ACM ...
Reducing the energy footprint of data centers continues to receive significant attention due to both its financial and environmental impact. There are numerous methods that limit the impact of both factors, such as expanding the use of renewable energy or participating in automated demand-response programs.

on the approach of achieving energy e ciency. The rst category is to seek energy proportionality with non-energy-proportional servers [53, 32, 31, 27, 35]. The second cate-gory is to build more energy-e cient architecture based on low-power CPU [38, 41, 49, 33, 43, 46, 29]. Improving energy-proportionality allows power draw to...

ENERGY PROPORTIONAL MEMORY SYSTEMS A DISSERTATION
costs running into millions of dollars, energy is an even more important criterion in datacenters. To increase computer system energy efficiency, we need memory systems that keep pace with processor efficiency gains. Currently, servers use DDR3 memory, which is designed for high bandwidth but not for energy proportionality. A system using 20%

cluster of nodes may adjust the number of active (power-consuming) nodes to the current demand and, thus, approx-imate energy proportionality. Based on these observations, we developed WattDB, a re-search prototype of a distributed DBMS cluster, running on lightweight, Amdahl-balanced nodes using commodity hard-ware.
The Case for Energy-Proportional Computing – Google Research
Achieving energy proportionality will require significant improvements in the energy usage profile of every system component, particularly the memory and disk subsystems. Although our experience in the server space motivates these observations, we believe that energy-proportional computing also will benefit other types of computing devices....
Managing server clusters on intermittent power [PeerJ]
First, several studies have shown that turning a server off when not in use is the most effective method for saving energy in server clusters (Chase et al., 2001; Pinheiro et al., 2001). Second, blinking extends the PowerNap ( Meisner, Gold & Wenisch, 2009 ) concept, which advocates frequent transitions to a low-power sleep state, as an ...
