CMS computing upgrade and evolution / Hernandez Calama, Jose (Madrid, CIEMAT) /CMS Collaboration
The distributed Grid computing infrastructure has been instrumental in the successful exploitation of the LHC data leading to the discovery of the Higgs boson. The computing system will need to face new challenges from 2015 on when LHC restarts with an anticipated higher detector output rate and event complexity, but with only a limited increase in the computing resources.

Challenging Data Management in CMS Computing with Network-aware Systems / Bonacorsi, Daniele (INFN, Bologna ; Bologna U.) ; Wildish, Anthony (Princeton U.) /CMS Collaboration
After a successful first run at the LHC, and during the Long Shutdown (LS1) of the accelerator, the workload and data management sectors of the CMS Computing Model are entering into an operational review phase in order to concretely assess area of possible improvements and paths to exploit new promising technology trends. In particular, since the preparation activities for the LHC start, the Networks have constantly been of paramount importance for the execution of CMS workflows, exceeding the original expectations - as from the MONARC model - in terms of performance, stability and reliability.

Data preparation for the Compact Muon Solenoid experiment / Franzoni, Giovanni (CERN) /CMS Collaboration
During the first 3 years of operation at the Large Hadron Collider, the Compact Muon Solenoid (CMS) experiment has collected data across evolving conditions of center of mass energy, instantaneous luminosity and collisions pile up. Following this evolution, the CMS collaboration has constantly strived to guarantee the prompt availability of high quality reconstructed data, in order to ensure early and sound physics results.

The Common Analysis Framework Project / Mascheroni, Marco (INFN, Milan Bicocca) /ATLAS and CMS Collaborations
ATLAS, CERN-IT, and CMS embarked on a project to develop a common system for analysis workflow management, resource provisioning and job scheduling in the distributed computing infrastructure based on elements of PanDA. After an extensive feasibility study and development of a proof-of-concept prototype, the project has now a basic infrastructure that can be used to support the analysis use case of both experiments with common services.

Physics Performance with the CMS Pixel Detector / Meier, Frank (Nebraska U.) /CMS Collaboration
A large fraction of the results produced by the LHC experiments during the first run were made possible by precision vertexing detectors. The all-silicon tracking detector of the CMS experiment uses a pixel detector to do vertexing. [...]

CMS Data preparation for Run II / Fabozzi, Francesco (INFN, Naples ; Basilicata U., Potenza) /CMS Collaboration
The Run II of the Large Hadron Collider will confront us with new challenges, mainly due to the higher number of interactions per bunch crossing and the reduced time distance between bunches. In order to be ready for the beginning of the run, in view of an early discovery, the CMS collaboration is currently evolving the infrastructure established during Run I to monitor the data quality, to validate the progresses on detector simulation, event reconstruction, physics objects definition, and to handle large production of simulated events.

Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at 8 TeV / Keaveney, James Michael (Vrije U., Brussels) /CMS Collaboration
A search is presented for standard model (SM) production of four top quarks (tttt) in pp collisions in the lepton + jets channel. The data correspond to an integrated luminosity of 19.6 fb$^{-1}$ recorded at a centre-of-mass energy of 8 TeV with the CMS detector at the CERN LHC. [...]
