Abstract

We discuss our experience with PROOF-Lite in a context of ATLAS Collaboration physics analysis of data obtained during the LHC physics run of 2009-2010. In particular we discuss PROOF-Lite performance in virtual and physical machines, its scalability on different types of multi-core processors and effects of multithreading. We will also describe PROOF-Lite performance with Solid State Drives (SSDs).
