The ATLAS Computing Model is under continuous active development. Previous exercises focussed on the Tier-0/Tier-1 interactions, with an emphasis on the resource implications and only a high-level view of the data and workflow. The work presented here considerably revises the resource implications, and attempts to describe in some detail the data and control flow from the High Level Trigger farms all the way through to the physics user. The model draws from the experience of previous and running experiments, but will be tested in the ATLAS Data Challenge 2 (DC2, described in other abstracts) and in the ATLAS Combined Testbeam exercises. An important part of the work is to devise the measurements and tests to be run during DC2. DC2 will be nearing completion in September 2004, and the first assessments of the performance of the computing model in scaled slice tests will be presented.
