Towards a Production Volunteer Computing Infrastructure for HEP

Following the successful inclusion of virtualisation to volunteer computing for theory simulations back in 2011, the use of volunteer computing with BOINC and CernVM has been extended to cover simulations for the LHC experiments ATLAS, CMS and LHCb. This paper describes the status of the BOINC volunteer computing platform at CERN used for LHC@home and how it has been designed to address a heterogeneous environment of different user communities with different computing infrastructure. The aim of the recent developments is to provide a volunteer computing platform that the experiments can build upon to exploit opportunistic resources. Furthermore, new developments of common solutions to span user authentication domains are explained
