Success here will mean making significant inroads in advancing basic and applied research in support of the overarching grand challenge: ultimately preventing earthquake disasters. A fundamental objective of NEES, and the purpose of NEESgrid, is to change the paradigm so that earthquake engineering research within the NEES Consortium becomes a collaborative effort rather than a collection of loosely coordinated research projects by individuals.

virtual organizations composed of geographically distributed people from multiple organizations and representing multiple disciplines. The name that the United Kingdom has chosen for its program, "e-Science," is particularly descriptive of what the committee believes NEES can accomplish with grid computing: revolutionary science and engineering enabled by distributed computing resources for distributed groups of people.

Web-based collaboration environments expand on this level of capability and provide chat rooms, online data, and document sharing and have the potential to enable broad participation across the university, industrial, and education communities. Videoconferencing between individuals and groups is another important mode of collaboration.

In addition, work is under way within the community to integrate additional collaboration capabilities, high-definition video, and analysis and visualization tools into the AccessGrid environment. All of these could one day be valuable to NEES, especially the high-definition video, which could be useful for teleobservation and telepresence activities.

While collaboration capabilities in general appear to generate broad enthusiasm on the part of NEES sites and potential NEES users alike, it was the committee's observation that NEES sites were generally skeptical of the idea of remote control of the experimental equipment, citing deep concerns about security, varying levels of investigator proficiency, human safety, and the integrity of expensive equipment. The NEESgrid user requirements team delved into this matter in its survey (Finholt et al., 2002)

is emerging as a basic enabling technology and lingua franca that provides the glue for associating data and metadata, along with related information such as scientific papers, documentation, and the electronic services that provide access to data and metadata. Numerous examples of XML-based scientific markup languages have recently begun to emerge, spanning the gamut of science, engineering, and commerce.

The NEES Consortium faces a challenge and enjoys the opportunity to foster partnerships in which other technology efforts and NEESgrid efforts collaboratively define the evolution of NEES data strategies in support of frontier research problems. In addition, emerging work in translational strategies among metadata standards will ultimately need to be explored, possibly building on emerging work in the development of domain ontologies a necessary step for the fusion of multiple disparate data holdings for integrative experimentation, simulation, and impact studies (i.e., the grand challenges set out in this report)

Unless formats can be defined in advance for researchers, the effort to convert project data into this standard format will be considerable and not within the budget of individual research projects. Consideration should be given to designating funding specifically for the development of standard NEES data formats, conversion of research data into the NEES formats, and curation of the data sets stored in the data repository.

Initial NEES efforts encompass identifying simulation codes that are of interest to the community and providing repositories and integrated execution sites for them so that participants may use them readily. NEES activities currently under way in data analysis and visualization focus on delivering analysis, simple visualization tools, and capabilities for accessing video streams and imaging from within the collaborative Web-based portal environment.

With terascale computational platforms already available and petascale systems on the horizon in 10 years, it will be technically possible to perform integrations of tremendous resolution for tsunamis and regional seismic events. Uncertainties about the source of seismic events and soil material properties at the scale needed to model ground motion and system performance for frequencies of engineering interest make it necessary to introduce stochastic modeling.

From page 97... ...
Such research endeavors would span the numerical simulation of seismic events and ground motion over large geographic regions; the simulation of tsunamis and the modeling of flood inundation; the physical and numerical simulation of infrastructure and building performance; event-impact prediction and assessment; collateral hazard analysis; damage evaluation; and emergency response. Rapidly evolving GIS capabilities will be invaluable for managing and analyzing the mas

BUILDING COMMUNITY NEES is a national facility targeted at fundamentally redefining traditional modes of earthquake engineering research. Building on the concept of a collaboratory, NEES has an explicit charter to enable and broadly serve researchers at universities across the United States as well as practitioners and researchers at private corporations and government facilities.
