Computing Technical Design Report
The baseline steady-state ATLAS Computing Model for the early years of data taking has been outlined. It presumes a well-planned, organized and maintained Virtual Distributed Computing Facility. Such a facility will support ATLAS production, simulation and analysis. A considerable degree of central organization will be required in the analysis activities given the volume of data to be processed in a world-wide system.
Consideration has also been given to the commissioning of the system with first data. It is essential that a considerable degree of flexibility both in data formats and in resource usage be retained to ensure rapid analysis of the early data and a swift understanding and calibration of the detector. Our continuing Data and Service Challenge activities are designed to refine the understanding of the Computing Model, and also to commission the required tools well in advance of the first data taking.
