SuperB production system for simulated events

The SuperB asymmetric e⁺e^- collider and detector to be built at the newly founded Nicola Cabibbo Lab will provide a uniquely sensitive probe of New Physics in the flavor sector of the Standard Model. Studying minute effects in the heavy quark and heavy lepton sectors requires a data sample of 75 ab^-1 and a peak luminosity of 10³⁶ cm^-2 s^-1. The SuperB Computing group is working on developing a production system for distributed event simulation capable to support the detector design definition and its performance evaluation studies. During last year the system has evolved from the point of view of job workflow, Grid services, and technologies adoption. A complete code refactoring and sub-component language porting now allows to sustain large distributed production cycles involving resources from three continents and Grid Flavors. In this paper we present a complete description of the production system, its evolution and its integration with Grid services; in particular, we will focus on the utilization of new Grid component features as in LB and WMS version 3.
