WebFountain is a platform for very large-scale text analytics applications that allows uniform
access to a wide variety of sources. It enables the deployment of a variety of document-level …

This paper surveys the research on power management techniques for high‐performance
systems. These include both commercial high‐performance clusters and scientific high …

Energy efficiency is a major concern in modern high-performance computing system design.
In the past few years, there has been mounting evidence that power usage limits system …

Scalability of the core frequency is a common feature of low-power processor architectures.
Many heuristics for frequency scaling were proposed in the past to find the best trade-off …

Power dissipation has become one of the most critical factors for the continued development
of both high-end and low-end computer systems. We present a complete system power …

Power consumption is a troublesome design constraint for emergent systems such as IBM's
BlueGene/L. If current trends continue, future petaflop systems will require 100 megawatts of …

Understanding the power dissipation behavior of an application/workload is the key to
writing power-efficient software and designing energy-efficient computer systems. Power …

Algorithms that have to process large data sets have to take into account that the cost of
memory access depends on where the data is stored. Traditional algorithm design is based …

Power and performance are two potentially opposing objectives in the design of a
supercomputer, where increases in performance often come at the cost of increased power …

ICTs (Information and Communication Technologies) are responsible around 2% of
worldwide greenhouse gas emissions (Gartner, 2007). And according to the …
