In this paper we study the effect of processor affinity on real-time scheduling algorithms in uniform multiprocessor environments. For this reason we compare our two previously proposed algorithms called EFDF and FLLF, with two well know algorithms, namely global EDF and global LLF. Despite its non-optimality, EDF is an appropriate algorithm to use on multiprocessors. However, the performance of the traditional algorithms such as EDF and LLF significantly degrades in overloaded situations. Moreover, they prod…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
