On the periodic behavior of real-time schedulers on identical multiprocessor platforms [article]

Emmanuel Grolleau
2013 arXiv   pre-print
This paper is proposing a general periodicity result concerning any deterministic and memoryless scheduling algorithm (including non-work-conserving algorithms), for any context, on identical multiprocessor  ...  Note that we do not claim that the given interval is minimal, but it is an upper bound for any cycle of any feasible schedule provided by any deterministic and memoryless scheduler.  ...  Existing periodicity results in a multiprocessor context The periodic behavior of schedulers has been studied in the context of global scheduling on multiprocessor platforms for specific scheduling algorithms  ...
