Description
The LHC Run II will confront us with new challenges, mainly due to the higher number of interactions per bunch crossing (pileup) and the reduced time distance between bunches. Moreover, the higher energy shifts the interest to complex physics objects such as boosted topologies for jet studies.
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 object definition, and to handle large scale Monte Carlo samples' production. Beside guaranteeing the readiness for Run II, this infrastructure serves as the basis to test detector upgrade proposals for the High-Luminosity LHC, for which an even higher pileup is expected.
This contribution will cover the development and operational aspects of data preparation at CMS for the Run II operations, reporting on how the experience gained in the operations for the Run I is serving the planning of the physics program for Run II.
