EO Grid Middleware How do we solve problems? l Communities committed to common goals -Virtual organizations l Teams with heterogeneous members & capabilities l Distributed geographically and politically -No location/organization possesses all required skills and resources l Adapt as a function of the situation -Adjust membership, reallocate responsibilities, renegotiate resources

EO Grid Middleware The Grid Vision “ Resource sharing & coordinated problem solving in dynamic, multi-institutional virtual organizations” -On-demand, ubiquitous access to computing, data, and services -New capabilities constructed dynamically and transparently from distributed services “When the network is as fast as the computer's internal links, the machine disintegrates across the net into a set of special purpose appliances” (George Gilder)

EO Grid Middleware A Little History (U.S. Perspective) l Early 90s -Gigabit testbeds, metacomputing l Mid to late 90s -Early experiments (e.g., I-WAY), software projects (e.g., Globus), application experiments l Major application communities emerging -Major infrastructure deployments are underway -Rich technology base has been constructed -Global Grid Forum: >1000 people on mailing lists, 192 orgs at last meeting, 28 countries
