We describe a heuristic for dynamically scheduling timeconstrained tasks in a distributed environment. When a task is submitted t o a n o de, the scheduling software tries to schedule the task locally so as to meet its deadline. If that is not feasible, it tries to locate another node where this could be done with a high probability of success. Nodes in the system inform each other about their state (viz-a-viz the availability of free cycles) usi n g a c ombination of broadcasting and gossiping. The performance of the proposed p r otocol is evaluated b oth analytically and via simulation. Based on our ndings, we argue that keeping a diverse availability pro le and using passive bidding (through gossiping) are b oth advantageous to distributed s c h e duling for real-time systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
