ATLAS computing Original Research Article

A summary of the ATLAS Computing Technical Proposal (The ATLAS Collaboration, CERN/LHCC/96-43) is given, outlining the plans of the ATLAS collaboration for computing in terms of software development, computing infrastructure, manpower and cost. We can only lay down the requirements, as they are known today, technical directions that we currently follow, and a rough estimate of the resources needed. Computing is instrumental to the success of the experiment. In many of the areas, we do not yet have solutions that are adequate to the scale of the problem in terms of complexity, data rate and data volume, organisational problems due to the world-wide dispersion of resources, and duration of the project.
