Sumario:Data taking in ATLAS has been going on for more than one year. The necessity of a computing infrastructure for data storage, access for thousands of users and process of hundreds of million of events has been confirmed in this period. Fortunately, this task has been managed by the GRID infrastructure and the manpower that also has been developing specific GRID tools for the ATLAS community. An example of a physics analysis, searches for the decay of a heavy resonance into a ttbar pair, using this infrastructure is shown. Concretely using the ATLAS Spanish Tier-2 and the IFIC Tier-3. In this moment, the ATLAS Distributed Computing group is working to improve the connectivity among centers in order to be ready for the foreseen increase on the ATLAS activity in the next years.
