Free Lunch: Exploiting Renewable Energy for Computing

Download Now Free registration required

Executive Summary

This paper argues for "Free Lunch", a computation architecture that exploits otherwise wasted renewable energy by co-locating data-centres with these remote energy sources, connecting them over a dedicated network, and providing a software framework that supports the seamless execution and migration of virtual machines in the platform according to power availability. This paper motivates and outlines the architecture and demonstrates its viability with a case study. Additionally, the authors discuss the major technical challenges facing the successful deployment of Free Lunch and the limiting factors inherent in its design.
