Scheduling, backfill, reservation, workload analysis.
On parallel systems, jobs that request a large fraction of the maximum resources available on the system may in cur poor wait time. This paper evaluates whether giving a reservation to every waiting job can improve large jobs without significantly degrading the performance of other jobs. Using a wide range of workloads, including more re cent workloads than SP2 workloads, and a more complete set of performance measures than in previous studies, we provide new observations of potential benefit and problem of reservation policies that give all jobs a reservation.
