Validation of ATLAS grid sites with HammerCloud — •Federica Legger, Philippe Calfayan, Günter Duckeck, Johannes Ebke, Johannes Elmsheuser, Christoph Anton Mitterer, and Rodney Walker — Ludwig-Maximilians-Universität München

The ATLAS Grid infrastructure consists of more than one hundred WLCG sites worldwide dedicated to both central production and user analysis activities. Every day more than 100000 jobs are continuously running. Automatic validation of each site for both analysis and production jobs is necessary to ensure the smooth operation of such a complex system. The HammerCloud framework provides such a testing service, with automatic exclusion from brokerage of sites failing the tests. Moreover within HammerCloud stress tests can be defined to test specific issues (validating new sites, evaluating performances after an hardware change, test new software releases and configurations). We report on the operation and results of functional testing and new developments in HammerCloud. These include testing of the ATLAS offline software nightly build releases distributed by CVMFS and testing storage setup in the new ATLAS xrootd federation (FAX).
