Meta-computing at D0

D0 Run II is one of the two large collider experiments at Fermilab and one of the largest currently running High Energy Physics Experiments in the world. Its amount of data, throughput of data processing, and the size of the collaboration present a unique challenge for the experimentʹs meta-computing system. To meet the challenge, the SAMGrid system is being developed to allow globally distributed, high-throughput data processing with many Grid features. At the core of the system is the mature data handling system, SAM. We add the Job and Information Management to the data handling to arrive at a complete Grid.
