Description

The ATLAS data taking is due to start in Spring 2009. In this contribution and given the expectation, a rigorous evaluation of the readiness parameters of the Spanish ATLAS Distributed Tier-2 is given. Special attention will be paid to the readiness to perform Physics Analysis from different points of view: Network Efficiency, Data Discovery, Data Management, Production of Simulated events, User Support and Distributed Analysis. The prototypes of the local computing infrastructures for data analysis set-up , the so-called Tier-3 , attached to the three sites that make up the Tier-2 are described. Several use cases of Distributed Analysis in the GRID system and local interactive tasks in the non-grid farms are provided in order to evaluate the interplay between both environments and to compare the different performances. The sharing between Monte Carlo Production and Distributed Analysis activities is also studied. The Data Storage and Management systems chosen are described and results on their performance are given.
