NSF funded 9/2000 @ $11.9M+$1.6M
- US-CMS High Energy Physics
- US-ATLAS High Energy Physics
- LIGO/LSC Gravity wave research
- SDSS Sloan Digital Sky Survey
- Strong partnership with computer scientists
Design and implement production-scale grids
- Develop common infrastructure, tools and services (Globus based)
- Integration into the 4 experiments
- Broad application to other sciences via “Virtual Data Toolkit”
Research organized around Virtual Data (see next slide)
- Derived data, calculable via algorithm
- Instantiated 0, 1, or many times (e.g., caches)
- “Fetch data value” vs “execute algorithm”
- Very complex (versions, consistency, cost calculation, etc)
