The CMS Framework for Alignment and Calibration

The ultimate performance of the CMS detector relies crucially on precise and prompt alignment and calibration of its components. A sizable number of workflows need to be coordinated and performed with minimal delay through the use of a computing infrastructure which is able to provide the constants for a timely reconstruction of the data for subsequent physics analysis. The framework supporting these processes is presented together with alignment and calibration results in simulated LHC start-up scenarios and from cosmic muons recorded with the solenoidal magnetic field being switched on and off.
