Computer science description: The increasing diffusion of cloud technologies is opening new opportunities for distributed and collaborative computing. Volunteer clouds are a prominent example, where participants join and leave the platform and collaborate by sharing their computational resources. The high dynamism and unpredictability of such scenarios call for decentralized self-* approaches to guarantee QoS. We present a simulation framework for collaborative task execution in volunteer clouds and propose one concrete instance based on Ant Colony Optimization, which is validated through a set of simulation experiments based on Google workload data. date: 2013-07-26 type: Working Paper type: NonPeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/1648/1/ucc2013.pdf identifier: Sebastio, Stefano and Amoretti, Michele and Lluch-Lafuente, Alberto A Computational Field Framework for Collaborative Task Execution in Volunteer Clouds.
