High speed communication across wide area networks is currently of great interest in computer communications industry. It is needed wherever a huge amount of data will be created and made available to remote computer systems. Areas of investigation in computer science are the coupling of supercomputers (metacomputing), high-resolution visualisation of data and distributed access to huge amounts of data.
This paper describes some issues to connect supercomputers for Metacomputing applications via an A T M gigabit link. Possible solutions based on different communication technologies are presented and the pros and cons f x the final implementation are discussed. TCP/LP tuning was investigated to achieve a maximal throughput.
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.
