Abstract
Detailed detector simulation and reconstruction of physics objects at the LHC are very CPU intensive and hence time consuming due to the high energy and multiplicity of the Monte-Carlo events and the complexity of the detectors. We present a dynamically configurable system for fast Monte-Carlo simulation and reconstruction (FAMOS) that has been developed for CMS to allow fast studies of large samples of Monte-Carlo events. Each single step of the chain - simulation, digitization and reconstruction, as well as combinations of chain links can be replaced by modules that sacrifice precision for speed. Fast and detailed modules have identical interfaces so that a change is fully transparent for the user. Currently, a complete set of the fastest possible implementation, i.e. going directly from the Monte-Carlo truth to reconstructed objects, has been implemented. It is about hundred to thousand times faster than the fully detailed simulation/reconstruction and provides tracks reconstructed by the inner tracker, clusters in calorimeters and trigger-Lvl1 objects and tracks reconstructed for the muon system of the CMS detector.
