Grid3: An Application Grid Laboratory for Science
Robert W. Gardner · CERN Document Server (European Organization for Nuclear Research) · 2005
We describe experiences from nine months of continuous operations of the Grid3 Laboratory, deployed as a result of the Grid2003 Project.The project was organized as an application-driven grid platform that would provide the production-scale services needed by the physics experiments of the Large Hadron Collider (LHC) at CERN (ATLAS and CMS), the Sloan Digital Sky Survey project, the gravitational wave search experiment LIGO, the BTeV experiment at Fermilab, applications in molecular structure analysis and genome analysis, and computer science research projects in such areas as job and data scheduling.The deployed infrastructure has been operating since November 2003 with 30 sites, a peak of over 3000 processors, work loads from 10 different applications exceeding 1300 simultaneous jobs, and data transfers among sites of greater than 2 TB/day.We describe the basic components of the infrastructure and results from its use in LHC data challenges.
