A Blueprint for Introducing Disruptive Technology into the Internet
A new class of geographically distributed network services is emerging, and the most effective way to design, evaluate, and deploy these services is by using an overlay-based testbed. Unlike conventional network testbeds, however, we advocate an approach that supports both researchers that want to develop new services, and clients that want to use them. This dual use, in turn, suggests four design principles that are not widely supported in existing testbeds: services should be able to run continuously and access a slice of the overlay's resources, control over resources should be distributed, overlay management services should be unbundled and run in their own slices, and APIs should be designed to promote application development. This talk describes this high-level vision, and reports the status and plan for the realization of the vision in PlanetLab.

Title Structured Data and the Grid: Access and Integration
Structured digital data are now fundamental to all branches of science and engineering; they play a major role in medical research and diagnosis, and underpin business and governmental decision processes. The advent of ubiquitous Internet computing and the ambition of today's enterprises has led to widespread collaboration in the creation, curation, publication, management and exploitation of these structured collections. As the scale of data increases and the sophistication of analyses develops the combination of large-scale data management and intensive computation using distributed resources becomes a recurrent necessity. This is a natural application for grids. The talk will identify the requirements raised by addressing the data intensive computations over a grid, report on progress towards building services that meet those requirements, and pose the research issues that they provoke.

GEON: Cyberinfrastructure for the Geosciences
In this talk, we will provide an overview of the GEON project, which is a multi-institution coalition of IT and Earth Science researchers to develop cyberinfrastructure for the Geosciences. The geoscientists in the project have identified two integrative science questions, related to terrane recognition and intra-plate deformations, which provide the motivation to develop the cyberinfrastructure. The regions of study are in the mid-Atlantic and the Rocky Mountains. The project is developing tools and technologies related to knowledge representation, data integration, grid computing, and advanced visualization, to enable geoscientists to address complex science questions. We will describe how the GEON Grid is being designed and implemented to serve the needs of this community. It is anticipated that multiple additional Geoscience groups will participate in this grid infrastructure. One that has recently received funding is the Chronos project, which has the mission to develop curated databases and associated access and visualization tools in order to produce a dynamic, global timescale to frame Earth history events and processes. Another that is underway is the HydroInformatics project, which has the goal of developing a national-scale Hydrologic Information System for monitoring surface and ground water resources. The presentation will highlight the Grid-enabled Mediation Services (GeMS) that are being developed at the San Diego Supercomputer Center to facilitate integrated access to replicated, distributed information.

Grid Services as Research Enabler
How should the research community respond to the emergence of the Open Grid Services Architecture? Will standardization of Grid interfaces encourage or stifle creativity? I argue that the definition of OGSA presents a major opportunity for the Grid research community, due to its encouragement of the critical mass, impact, large-scale deployment, and synergies required for rapid progress across a range of fronts. I propose some specific steps that the research community can take to encourage, contribute to, and leverage OGSA developments.

NEESGrid: Earthquake Engineering Meets the Grid
The discipline of Earthquake Engineering is focused on understanding how our physical infrastructure, buildings, bridges, roads, etc., responds to earthquakes. Traditionally, this understanding has been achieved through experimental observations: either by collecting data from real earthquakes, or by subjecting models to simulated earthquakes using large, expensive test facilities such as shake tables, reaction walls, and centrifuges. To the earthquake engineering communities, these experimental facilities play the same role as supercomputers do to the numerical simulation community: they are critical to advancing the discipline, they are expensive, and are often more effectively used if shared. In addition, numerical simulation is playing an increasingly important role in earthquake engineering, and consequently, the computational infrastructure complements the experimental infrastructure to form the core platform on which earthquake engineering advances. The emergence of Grid infrastructure creates an exciting opportunity for the earthquake engineering community. At its most basic, the Grid offers better access to the experimental infrastructure which is so critical to understanding the response of structures. However, more significant, the Grid offers the possibility to create entirely new types of experiments: combining experimental facilities with numerical simulation, creating a new virtual facility on which even greater understanding can be obtained. Recognizing the impact that this type of across the board sharing and collaboration can have on earthquake engineering, the National Science Foundation has created a program called the Network for Earthquake Engineering and Simulation. In my talk, I will describe NEESgrid, a Grid based infrastructure that is being developed to advance this vision of a new, network based approach to earthquake engineering experimentation. I will discuss the NEESgrid architecture and describe how NEESgrid is being used to perform new classes of earthquake engineering experiments.

The EU DataGrid: Building and Operating a Large Scale Grid Infrastructure
The EU DataGrid project (EDG) has as its aim to develop a large-scale research testbed for Grid computing. The Project is in its final phase and a large scale testbed has been up and running continuously since the beginning of 2002. Three application domains are using this testbed to explore the potential Grid computing has for their production environments: Particle Physics, Earth Observation and
Biomedics. The EDG testbed, spanning some 20 major sites all over Europe as well as sites in the US and Asia, offers over 10,000 CPUs
and 15 TB of storage to its more than 350 users; it is one of the largest Grid infrastructures in the world.
In this talk we present the architecture of the EDG middleware and critically review its design. Based on the experiences our user
community has gained during production tests we identify successes of EDG as well as areas that need further improvement and discuss which changes will be applied to strengthen the software over the next few months. We end the talk with on outlook on how EDG middleware is expected to be further applied and maintained after the end of the project.
