Middleware Other Main Fields [None Given] Abstract Keywords: SAM, Data Management, HEP, PPDG, GridPP We present the SAMGrid project, formerly known as the d0-grid project. It is fueled by the US funding through the PPDG collaboration and proceeds in close cooperation with the GridPP efforts for D0. The mission of our project is to enable truly globally distributed computing for D0 (and CDF), by means of augmenting the SAM data handling system with grid services for job and information management. The classes of user jobs are analysis, reconstruction and Monte-Carlo, with Monte-Carlo being the key area of interaction with GridPP. We present the general architecture of SAMGrid, highlight the design decisions that enable MC on the grid, and describe our first successes running MC jobs on the grid. Through continued cooperation of SAMGrid with GridPP, we plan to further facilitate grid computing of UK physicists and beyond. Remarks [None Given]
