The Large Hadron Collider (LHC) experiments will collect unprecedented data volumes in the next Physics run, with high pile-up collisions resulting in events that require a complex processing. Hence, the collaborations have been required to update their Computing Models to optimize the use of the available resources and control the growth of resources, in the midst of widespread funding restrictions, without penalizing any of the Physics objectives.

Architectures and methodologies for future deployment of multi-site Zettabyte-Exascale data handling platforms
/ Acín, V (Barcelona, IFAE ; PIC, Bellaterra) ; Bird, I (CERN) ; Boccali, T (INFN, Italy ; INFN, Pisa) ; Cancio, G (CERN) ; Collier, I P (Rutherford) ; Corney, D (Rutherford) ; Delaunay, B (CNRS, France ; CC, Villeurbanne) ; Delfino, M (Barcelona, Autonoma U. ; footnote (Correspondence) to be removed ; PIC, Bellaterra) ; dell'Agnello, L (INFN, Italy ; INFN, CNAF) ; Flix, J (Madrid, CIEMAT ; PIC, Bellaterra) et al.
Several scientific fields, including Astrophysics, Astroparticle Physics, Cosmology, Nuclear and Particle Physics, and Research with Photons, are estimating that by the 2020 decade they will require data handling systems with data volumes approaching the Zettabyte distributed amongst as many as 10(18) individually addressable data objects (Zettabyte-Exascale systems). It may be convenient or necessary to deploy such systems using multiple physical sites [...]

The LHC Tier1 at PIC: experience from first LHC run
/ Flix, J (Madrid, CIEMAT ; PIC, Bellaterra) ; Perez-Calero Yzquierdo, A (Madrid, CIEMAT ; PIC, Bellaterra) ; Acción, E (Barcelona, IFAE ; PIC, Bellaterra) ; Acin, V (Barcelona, IFAE ; PIC, Bellaterra) ; Acosta, C (Barcelona, IFAE ; PIC, Bellaterra) ; Bernabeu, G (Madrid, CIEMAT ; PIC, Bellaterra) ; Bria, A (Barcelona, IFAE ; PIC, Bellaterra) ; Casals, J (Madrid, CIEMAT ; PIC, Bellaterra) ; Caubet, M (Madrid, CIEMAT ; PIC, Bellaterra) ; Cruz, R (Barcelona, IFAE ; PIC, Bellaterra) et al.
This paper summarizes the operational experience of the Tier1 computer center at Port d’Informació Científica (PIC) supporting the commissioning and first run (Run1) of the Large Hadron Collider (LHC). The evolution of the experiment computing models resulting from the higher amounts of data expected after the restart of the LHC are also described..
