Meta-Scheduling and Task Reallocation in a Grid Environment
Résumé
In this paper, we study the impact of task reallocations/migrations on a Grid platform, composed of parallel resources, each supervised by a batch scheduler. Results of simulations using real life traces show that gains of 40\% can be attained on the average waiting time of jobs even if tasks are initially mapped by a meta-scheduler on the cluster giving the best completion time.
