Volunteer clouds are a prominent example, where participants join and leave the platform and collaborate by sharing computational resources. The high complexity, dynamism and unpredictability of such scenarios call for decentralized self-* approaches. We present in this paper a framework for the design and evaluation of self-adaptive collaborative task execution strategies in volunteer clouds. As a byproduct, we propose a novel strategy based on the Ant Colony Optimization paradigm, that we validate through simulation-based statistical analysis over Google workload data. date: 2014-01-23 date_type: submitted number: institution: IMT Institute for Advanced Studies Lucca citation: Sebastio, Stefano and Amoretti, Michele and Lluch-Lafuente, Alberto A Computational Field Framework for Collaborative Task Execution in Volunteer Clouds.
