Abstract: In this paper, we present work on an EPSRC e-Science project whose purpose is to investigate the effects of SLA based approaches for parallel computing job scheduling. We considered a coordinator based architecture, where the Coordinator forms SLAs with Users and Resources (parallel servers). The paper focuses on a case study which evaluates different policies for the negotiation of SLAs between the Coordinator and the Resources. We show that the use of information available in the SLAs agreed by the User may fundamentally alter the behaviour of the Coordinator and hence the performance of the overall system. These effects need to be understood more deeply before new designs can take advantage of the possibilities offered by SLAs.
