 Towards Energy Proportionality for Large-Scale Latency ...
nificantly improves the energy proportionality of WSC systems, as demonstrated by a real implementation in a Google search cluster. PEGASUS uses request latency statistics to dynamically adjust server power management limits in a fine-grain manner, running each server just fast enough to meet global service-level latency objectives....
KnightShift: Scaling the Energy Proportionality Wall ...
Abstract: Server energy proportionality has been improving over the past several years. Many components in a system, such as CPU, memory and disk, have been achieving good energy proportionality behavior. Using a wide range of server power data from the published SPEC power data we show that the overall system energy proportionality has reached 80%....
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.

Measuring Energy Consumption of a Database Cluster
To avoid the limitations of a single large server in achieving energy proportionality, we are going to propose a new approach by employing commodity hardware to form an energy-proportional computing cluster. Small-scale server nodes (aka. wimpy nodes [AFK+09]) can be independently turned on and off, thus providing better scalability in terms of ......
Warehouse-Scale Computing: The Machinery That Runs the ...
WSCs are built of low-end or mid-range server-class computers connected in racks of 40 to 80 units by a first-level networking switch; each switch connects in turn to a cluster-level network fabric that ties together all of the racks. The clusters, which tend to be composed of several thousand servers, constitute the primary units of computing ...
