Abstract:On many-core Network-on-Chips (NoCs), communication is on the critical path of system performance and contended synchronization requests may cause large performance penalty. Different from conventional algorithm-based approaches, the paper addresses the barrier synchronization problem from the angle of optimizing its communication performance and proposes cooperative communication as a means to achieve efficient and scalable all-to-all barrier synchronization on mesh-based many-core NoCs. With the cooperative … 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.
