The portable batch scheduler and the maui scheduler on linux clusters

The motivation for a stable, efficient, backfill scheduler that runs in a consistent manner on multiple hardware platforms and operating systems is outlined and justified in this work. The combination of the Maui Scheduler and the Portable Batch System (PBS), are evaluated on several cluster solutions of various size, performance and communications profiles. The total job throughput is simulated in this work, with particular attention given to maximizing resource utilization and to the execution of large parallel jobs.
