Abstract

The majority of non-coordinated decentralized meta-schedulers in a Federated Grid perform scheduling strategies without taking into account resources' current load or specific resource owners' internal demands, leading to suboptimal schedules. Clearly, these policies increase the number of job migrations, the number of messages generated per re-scheduled job, and also the application makespan. The main purpose of the present study is to analyze the effect of applying self-adjusting resource sharing policies to previously proposed performance based scheduling strategies. For example, when a resource is near saturation or has an internal peak demand, it can decide not to accept new external jobs. On the other hand, when a job owner receives the previous action, it can decide not to submit temporally more jobs to that resource. In this way, the proposed self-adjusting resource sharing policies save time and communication bandwidth by reducing the number of jobs migrations, and thus, avoiding the generation of the corresponding messages per re-scheduled job. At the same time, the new resource sharing strategies improve application makespan and resource performance objective functions while maintaining infrastructure owners complete autonomy.
