Results of the LHCb experiment Data Challenge 2004

The LHCb [1] experiment performed its latest Data Challenge during 2004; the first phase (Monte Carlo production) lasted from May to August 2004. The main goal of the Data Challenge was to stress test the LHCb production system and to perform distributed analysis of the simulated data. The LHCb prod...

description The LHCb [1] experiment performed its latest Data Challenge during 2004; the first phase (Monte Carlo production) lasted from May to August 2004. The main goal of the Data Challenge was to stress test the LHCb production system and to perform distributed analysis of the simulated data. The LHCb production system called DIRAC [2] provided all of the necessary services for the Data Challenge: Production and Bookkeeping databases, File catalogs, Workload and Data Management systems, Monitoring and Accounting tools. It enabled resources of more than 20 LHCb production sites as well as the LCG2 grid resources to be accessed in a consistent way. 187 Million events constituting 62 TB of data were produced and stored in 5 Tier 1centers. This paper will present the Data Challenge results, the experience gained utilizing DIRAC native sites and the LCG grid as well as further developments necessary to scale to the ultimate needs of the LHCb experiment.
