Multiprocessor Real-Time Scheduling with Hierarchical Processor Affinities
2016
2016 28th Euromicro Conference on Real-Time Systems (ECRTS)
Many multiprocessor real-time operating systems offer the possibility to restrict the migrations of any task to a specified subset of processors by setting affinity masks. A notion of "strong arbitrary processor affinity scheduling" (strong APA scheduling) has been proposed; this notion avoids schedulability losses due to overly simple implementations of processor affinities. Due to potential overheads, strong APA has not been implemented so far in a real-time operating system. We show that, in
