Backfilling is well known in parallel job scheduling to increase system utilization and user satisfaction over traditional non-backfilling scheduling algorithms, which allow small jobs from the back of the queue to execute before larger jobs arriving earlier, and resources could be reserved to protect the latter from starvation. This paper proposed a relaxed backfill scheduling mechanism supporting...
The peer-to-peer (P2P) live video streaming system has been demonstrated to have great potential in the public Internet; the large-scale deployment of such systems, however, critically relies on how effective they can deal with the high dynamics encountered, in particular during flash crowd. The rationale behind is that the scaling in P2P live video streaming systems is heavily determined by the timing...
In standard backfill algorithms, a job will be terminated immediately it has been processed for its estimated runtime. This drives users not to provide tight estimates to make their jobs to be scheduled earlier but at the risk of being killed. This paper presents an enhanced mechanism to tolerate underestimated jobs by continuing processing them on condition that they will not delay any other running...
