Description
The SuperB asymmetric energy 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 luminosity target of 10^36 cm-2 s-1.
In this work we will present our evaluation of the DIRAC Distributed Infrastructure for use in the SuperB experiment based on the two use cases:
End User Analysis and Monte Carlo Production. We will present:
1) The test bed layout with DIRAC site and service configurations and the efforts to enable and manage OSG-EGI interoperability.
2) Our specific use cases ported to the DIRAC test bed with the computational and data management requirements and the DIRAC subsystem configuration.
3) The test results obtained from running both SuperB Monte Carlo and end user analysis with details about the performance achieved, the efficiency and the failures that occurred during the tests.
4) An evaluation and comparison of the two catalogue systems provided by the DIRAC framework, LFC (LHC File Catalogue) and DIRAC File Catalog in terms of features, performance and reliability.
5) Evaluation of capabilities and performance tests of the DIRAC Cloud capabilities as potentially applicable to SuperB computing.
6) A comparison of DIRAC with other submission systems available in the HEP community with pros and cons of each system.
