Description
We study the performance of different ways of running a physics analysis in preparation for the analysis of petabytes of data in the LHC era. Our test cases include running the analysis code in a Linux cluster with a single thread in ROOT, with the Parallel ROOT Facility (PROOF), and in parallel via the Grid interface with the ARC middleware. We use of the order of millions of Pythia8 generator level QCD multi-jet events to stress the analysis system. The performances of the test cases are reported.
