In this paper, we investigate the use of application-specific hints when scheduling jobs on a Computational Grid, as these jobs can expose widely differing characteristics regarding CPU and I/O requirements. Specifically, we consider hints that specify the relative importance of network and computational resources w.r.t. their influence on the associated application's performance. Using our ns-2 based Grid Simulator (NSGrid), we compare schedules that were produced by taking application-specific hints into account to schedules produced by applying the same strategy for all jobs. The results show that better schedules can be obtained when using these scheduling hints intelligently.
Arbitrarily divisible workloads are present in a large class of scientific applications, such as N-body simulations, Monte Carlo simulations, CFD applications, and others. Divisible load theory (DLT) provides a tracta...
