Evaluation of Coordinated Grid Scheduling Strategies

—Grid computing has emerged as a way to share geographically and organizationally distributed resources that may belong to different institutions or administrative domains. In this context, the scheduling and resource management is usually performed by a grid resource broker. The scheduling task consists of distributing the jobs among the different centers resources and the need to coordinate the grid with the underlying scheduling levels which have already been identified. However, there is still a lack of policies for this approach. In this paper we describe and evaluate our coordinated grid scheduling strategy. We take as a reference the FCFS job scheduling policy and the matchmaking approach for the resource selection. We also present a new job scheduling policy based on backfilling (JR-backfilling) that aims to improve the workloads execution performance, avoiding starvation and the SLOW-coordinated resource selection policy that considers the average bounded slowdown of the ...
