Constraint Programming Based Large Neighbourhood Search for Energy Minimisation in Data CentresNS) method to solving this challenging problem. We present empirical results that demonstrate that the industrial benchmarks can be solved to near optimality using our approach. Our CP-LNS method provides a fast and practical approach for finding high quality solutions for lowering electricity costs in data centres.

Cost Evaluation of Migrating a Computation Intensive Problem from Clusters to Cloudt with the cost of solving it in a pure Cloud scenario. For this last, a detailed cost estimation is conducted according to the data extracted from the actual execution of a reduced dataset on Amazon EC2. As a result, the suitability of using Cloud-based solutions to solve large and complex scientific problems is discussed.
