Abstract

Fast networks have made it possible to aggregate distributed CPU, memory, storage, and data to provide the potential for application performance superior to that attainable on any single system. However, achieving such performance on these metacomputing systems has proved to be difficult. Experience with the I-WAY [DFP + ss] and other metacomputing platforms demonstrates that effective application scheduling is critical to the achievement of performance for metacomputing applications. Currently, application developers develop customized application schedules to achieve performance on a metacomputer. Such application-centric schedules promote the performance of the application by evaluating system performance in terms of application resource requirements. To formalize and generalize the, as yet, ad hoc notion of application-centric scheduling emerging from the practices of metacomputing application developers [EMRP, SAR, GWP93], we are developing metacomputing scheduling agents calle...
