Abstract:The design of modern operating systems is based around the concept of memory as a cache for data that flows between applications, storage, and I/O devices. With the increasing disparity between I/O bandwidth and CPU performance, this architecture exposes the processor and memory subsystems as the bottlenecks to system performance. Furthermore, this design does not easily lend itself to exploitation of new capabilities in peripheral devices, such as programmable network cards or special-purpose hardware acceler… 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.
