Outstanding Paper Award: Fair Lateness Scheduling: Reducing Maximum Lateness in G-EDF-Like Scheduling

Existing research in soft real-time scheduling has focused on determining tardiness bounds given a scheduling algorithm. In this paper, we study lateness bounds, which are related to tardiness bounds, and propose a scheduling algorithm to minimize lateness bounds, namely the global fair lateness (G-FL) algorithm. G-FL is a G-EDF-like scheduler, but has lower maximum lateness bounds than GEDF. Due to its G-EDF-like nature, it can be used within existing systems that implement arbitrary-deadline G-EDF, and with existing synchronization protocols. Therefore, we argue that G-FL should replace G-EDF for SRT applications.
