| summary | In this talk first the basics of energy efficiency of PCs and legacy operating systems are presented. The talk then covers the current outcomes of a research project called Virtual Home Environments (VHE), which aims to provide a Grid for home computers. VHE is meant to enable resource sharing between distributed home computers in a fully decentralized, yet reliable, fair and secure way. Since in many homes, computers are continuously running in order to provide always-on services like downloads or in the future home management, an important target of VHE is to aggregate always-on services on a small number of computers such that
a possibly large number of others can be hibernated.
In this way VHE aims at massively saving energy costs. Inside VHE several lines of research are going on. On the theoretical side we try to understand under which circumstances energy can be saved or not. Thus we create analytical and simulation models for various application types. On the practical side we are currently Implementing a prototype based on FreePastry that can move tiny virtual machines between computers. During the talk, the architecture and important system constraints of VHE will be explained, and results from modeling and experiments with the prototype will be shown. |
