CDF and D0 are both highly distributed collaborations, with many physicists and computing resources. Making use of that potential has been an issue from the start for D0 (Monte Carlo generation) and for CDF more recently. These efforts are going to grow. The SAM data handling system, used from the beginning by D0 and recently by CDF, is being used/modified for grid/distributed computing.
