Resource reconfiguration policy based on execution time estimation in computational grids

Intrinsic properties of the Computational Grid can be defined as dynamicity and unpredictability. Those properties lead the degradation of the performance and failure of system. In this paper, we propose the resource reconfiguration algorithm based on temporal execution time estimation method. Resource reconfiguration means that reshuffling the current available resource set for maintaining the quality level of the resources. Our approach shows the increase of the stability of execution environment as well as decrease the completion time compare to the method that is not adapted the resource reconfiguration.
