Abstract
This paper summarizes ten years of operational experience of the WLCG Tier-1 computer centre at Port d’Informació Científica (PIC), which serves the ATLAS, CMS and LHCb experiments. The centre, located in Barcelona (Spain), has supported all of the commissioning activities be- fore the Large Hadron Collider (LHC) produced real collisions, it has continuously adapted to the new requirements, introducing new technologies as they became available, and it has grown significantly in resources offered to the LHC experiments, while maintaining top reliability levels as compared to other centres. Additional work has been done in the last years to reduce the power costs of the Tier-1 centre, and to prepare for the next challenges that are expected to come. Some thoughts on how the current WLCG system could evolve are also presented.
