Hu/Vitek abstractLarge-scale compute-cycle sharing for complex and large scientificapplications is a long standing challenge in distributedcomputing. Many cycle-sharing systems have been developed and havedelivered orders of magnitude improvement in available resources.Nevertheless they are limited in their performance or capability.Furthermore, other forms of resource sharing and coordinationare needed to achieve truly distributed access to scientific infrastructure.The goal of this project is contribute to the national science andtechnology infrastructure by developing enabling technologies forvirtual laboratories open to researchers from all disciplines. Thisinfrastructure will leverage resources in peer-to-peer computing andprogramming languages to deliver an alternative architectural modelfor resource sharing over wide area networks. The self-organizingaspects of peer-to-peer networks promise to eliminate much of thedifficulty required to configure and maintain a large-scale globallydistributed computing and control system, and decentralization removes thepotential bottleneck and single point of failure of centralizedservice nodes. This project's contributions will be to provideabstractions for Peer-to-peer Computing based on extensions to theobject-oriented programming model and to develop a Peer-to-peerInfrastructure which extends the current peer-to-peer networksdeveloped for routing and data-centric applications.This project will work collaborativey with the DARPA ProgramComposition for Embedded Systems (PCES) initiative to apply the proposed resource-balancing techniques developed in this projectto sensor networks and distributed real-time systems of national importance.The educational impact of the proposed research includes integrationof advanced distributed systems research into both undergraduate andgraduate curricula, and outreach activities that involve high schoolsstudents into active participation in Internet-scale computing.
