  3. Experience doing Analysis in the US • Access to CMS MC Datasets much improved over the last year • All work accomplished solely on US Computing Facilities • Tier-1 and Tier2 • FNAL Tier-1 CMS User Analysis Facility • Excellent access to both interactive logins and batch queues • helps to avoid the overhead of immature “Grid” tools • Primarily used for JetMET Datasets • QCD, ttbar, W+jets, Z+jets, WW/ZZ/ZW+jets, etc • In the past, UAF data access sometimes difficult or batch system overloaded • More resources, better data handling  much better access now! • UF Tier-2 • Significant effort to • locate important datasets (mSUGRA, QCD, etc) at Florida • install and maintain CMS software in Florida • Ability to work at the UF Tier-2 has proven mission critical to meeting deadlines • Overall, support for analysis in the US has been adequate to good and is significantly improving with time
