Sub Farm Interface of the ATLAS Dataflow System

摘要

Sub Farm Interface is the event builder of the ATLAS(A Toroidal LHC ApparatuS) Dataflow System. It receives event fragments from the Read Out System, builds full events and sends complete events to the Event Filter for high level event selection. This paper describes the implementation of the Sub Farm Interface. Furthermore, this paper introduces some issues on SFI(Sub Farm Interface) optimization and the monitoring service inside SFI.
