The WorldGRID testbed was created in the fall 2002 to test the feasibility of forming a computational grid consisting of sites in the U.S. and Europe. The goal was to establish connectivity and interoperability of hardware installed with Grid components available on both sides of the Atlantic. The experiment culminated in demonstrations presented at the IST in Copenhagen and SC’02 in Baltimore. Applications from ATLAS, CMS, SDSS and LIGO were successfully operated on the established worldwide grid. Eighteen sites from sixteen institutions in Italy, Spain, Switzerland, U.K., Germany, Portugal and the U.S. participated in the WorldGRID demonstration experiment.

WorldGRID was a project of iVDGL (international Virtual Data Grid Laboratory), a global Data Grid that will serve forefront experiments in physics and astronomy. Its computing, storage and networking resources in the U.S., Europe, Asia and South America provide a unique laboratory that will test and validate Grid technologies at international and global scales. Sites in Europe and the U.S. will be linked by a multi-gigabit per second transatlantic link funded by the European DataTAG project.
