UT Grid is a comprehensive campus cyber-infrastructure project to integrate the numerous and diverse computational, visualization, storage, data and information, and instrument/device resources of The University of Texas at Austin (UT). This joint ...

GridPort is a toolkit for developing Web-based portals and applications for computational science on top of underlying distributed and grid computing infrastructure. GridPort aggregates grid services from popular grid software packages and provides ...

PlanetLab and Globus Toolkit are gaining widespread adoption in their respective communities. Although designed to solve different problems-PlanetLab is deploying a worldwide infrastructure testbed for experimenting with network services, while Globus ...

This paper presents a data management solution which allows fast Virtual Machine (VM) instantiation and efficient run-time execution to support VMs as execution environments in Grid computing. It is based on novel distributed file system virtualization ...

Increasingly, a number of applications rely on, or can potentially benefit from, analysis and monitoring of data streams.Moreover, many of these applications involve high volume data streams and require distributed processing of data arising from a ...

We describe the implementation and evaluate the performance of a Replica Location Service that is part of the Globus Toolkit Version 3.0. A Replica Location Service (RLS) provides a mechanism for registering the existence of replicas and discovering ...

Grid computing has excited many with the promise of access to huge amounts of resources distributed across the globe. However, there are no largely adopted solutions for automatically assembling grids, and this limits the scale of today's grids. Some ...

Distributed hash tables (DHTs) provide a scalable mechanism of mapping keys onto values.DHTs are designed for fully decentralized, yet efficient object location in peer-to-peer systems.The ad-hoc and dynamic nature of P2P networks motivated existing ...

Service composition is highly desirable in peer-to-peer (P2P) systems where application services are naturally dispersed on distributed peers. However, it is challenging to provide high quality and failure resilient service composition in P2P systems ...
