Multithreaded User Space Multiprotocols: Experiments with Collaborative Multimedia

Abstract

This research is motivated by emerging virtual collaboratories, distributed multimedia, and scalable distributed computing applications on modern heterogeneous networks of machines. It has had a humble origin, namely, a simple threads system (Ariadne) that was developed in our software laboratory (PacsLab) at Purdue. The Ariadne project has since expanded in scope, matured, and won recognition as a powerful supporting infrastructure for timer-enhanced multithreaded distributed computing. This is mainly due to its portability, efficiency and support for thread-migration. Ariadne has been used to support optimistic distributed simulations on large Sun and SGI workstation clusters, the IBM SP/2, and the Intel Paragon. It has led to the development of a novel sister threads system, (Arachne) which supports thread-migration on heterogeneous networked platforms. The funds provided by this award have enabled us to set up a multiprocessor cluster on which we can conduct experiments on thread migration, protocols and collaborative computing. These experiments are currently in progress.
