Reducing Tardiness under Global Scheduling by Splitting Jobs
2013
2013 25th Euromicro Conference on Real-Time Systems
Under current analysis, tardiness bounds applicable to global earliest-deadline-first scheduling and related policies depend on per-task worst-case execution times. By splitting job budgets to create subjobs with shorter periods and worst-case execution times, such bounds can be reduced to near zero for implicit-deadline sporadic task systems. However, doing so will result in more preemptions and could create problems for synchronization protocols. This paper analyzes this tradeoff between
