Abstract:The efficient management of conflicts among concurrent transactions constitutes a key aspect that hardware transactional memory (HTM) systems must achieve. Scalable HTM proposals so far inherit the cache-based style of conflict detection typically found in bus-based systems, largely unaware of the interactions between transactions and directory coherence. In this paper, we demonstrate that the traditional approach of detecting conflicts at the private cache levels is inefficient when used in the context of a d… Show more
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.
