Evaluating the Impact of Soft Walltimes on Job Scheduling Performance
Original language description
For two decades researchers have been analyzing the impact of inaccurate job walltime (runtime) estimates on the performance of job scheduling algorithms, especially in case of backfilling. Several studies analyzed the pros and cons of using accurate vs. inaccurate estimates. Some researchers focused on the ways users of the system can be moti- vated to provide more accurate runtime estimates. The recent addition of so-called "soft walltime" parameter in the widely used PBS Professional enables a system administrator to actually use some of these techniques to refine user-provided walltime estimates. The obvious question of a sys- tem administrator is whether such walltime predictions are useful and "safe" and what will be the impact on the overall system performance. In this work, we use several detailed simulations to analyze the actual impact of using soft walltimes in a job scheduler, discussing the scenarios when such "refined" estimates can be meaningfully used.
