SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Outline n The earthquake engineering community n The George E. Brown, Jr. Network for Earthquake Engineering Simulation n NEESgrid – the collaboratory element of NEES n Challenges & Successes n The field of dreams

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN The earthquake engineering community n Research –University-based –Funded by NSF and industry –Focus on simulation Physical models (e.g., reduced scale specimens) Numerical models (e.g., finite element analysis) n Practice –Professional firms –Structural engineering (e.g., earthquake remediation) –Formulation of uniform building codes –Lifelines (e.g., ensure survival of roads, gaslines, power distribution)

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN NEES expectations n Community survey (2002) Stratified on region (six regions – CA, NW, SW, MW, SE, NE) and sub-field (e.g., structural, geotechnical etc.) EERI membership roll and key tsunami mailing lists as sampling frame n = 361 (99 responses; 27%) n Workshop survey (2002) Registered participants in nineteen of the twenty regional workshops –The survey administration was not ready for the first workshop held in Charleston, SC n = 287 (260 responses; 91%)

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Summary of survey results n Workshop and community respondents share consensus about NEES expectations –…but level of agreement is much higher among workshop respondents n Access to experimental data is paramount –…and is more important than access to experimental facilities for both workshop and community respondents n Producing standard data formats is a critical goal n Workshop respondents skewed toward academic, structural earthquake engineers

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Why is NEES exciting? n Funding –scientists recruited through the NEES equipment site program and through the NEES grand challenge program n Recognition –innovative system –highly visible to earthquake engineering and computer science communities (e.g., SC 2002 demo) n Novel capabilities –first operational use of Globus/OGSA technology –“hybrid” operations -- combining numerical and physical simulations

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN NEESgrid – the collaboratory element of NEES n Primary –Shared instrument –Community data system n Secondary –Distributed research center –Virtual community of practice

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Technology involved n Globus/OGSA (USC ISI and ANL) –GSI and Gridftp n CHEF (Michigan) n Telepresence systems (ANL) n Data repository (NCSA) n Deployment, operations, and support (NCSA)

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN The field of dreams I was sitting on the verandah of my farm house in eastern Iowa when a voice clearly said to me, “If you build it, he will come.” – Ray Kinsella in Shoeless Joe, by W.P. Kinsella Image source:

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Building it so they will come… n Balance contributions (pp in the Atkins report) –Weight domain science too heavily? Overemphasize procurement of existing technologies Computer scientists become viewed as “merely” consultants and implementers –Weight computer science too heavily? End user needs insufficiently addressed Emphasis on novelty at the expense of usability and stability Source: Atkins report --

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Innovation Extrapolatio n Social &Technological Forces digital libraries computational grids video conferencing electronic journals distance learning electronic commerce collaboratories community networks e-science Innovation vs. extrapolation

SCHOOL OF INFORMATION UNIVERSITY OF MICHIGAN Building it so they will come… n Give users objects to think with (scenarios, mock-ups, prototypes) n Be patient…let users convince themselves n Know where you’ve been (collect baseline data) and what’s changed (collect data as you go along)
