| GAUDI- The Software Architecture and Framework for building LHCb Data Processing Applications (2008) | |||||||||||||||
Abstract | |||||||||||||||
| We present the strategy that has been adopted for the development of the software system for the LHCb experiment. This strategy follows an architecture-centric approach as a way of creating a resilient software framework that can withstand changes in requirements and technology. The software architecture, called GAUDI, covers event data processing applications in all processing stages from the high level triggers in the on-line system to the final physics analysis. We present our major architectural design choices and outline the arguments that led to these choices. Several iterations of a software framework based on this architecture have been released and the framework is now being used by the physicists of the collaboration to facilitate the development of data processing algorithms. Object oriented technologies have been used throughout. | |||||||||||||||
