| Summary:

The XENON experiment is looking for non-baryonic particle dark matter in the
universe. The setup is a dual phase time projection chamber (TPC) filled with
3200 kg of ultra-pure liquid xenon. The setup is operated at the Laboratori
Nazionali del Gran Sasso (LNGS) in Italy. We present a full overview of the
computing scheme for data distribution and job management in XENON1T. The
software package Rucio, which is developed by the ATLAS collaboration,
facilitates data handling on Open Science Grid (OSG) and European Grid
Infrastructure (EGI) storage systems. A tape copy at the Center for High
Performance Computing (PDC) is managed by the Tivoli Storage Manager (TSM).
Data reduction and Monte Carlo production are handled by CI Connect which is
integrated into the OSG network. The job submission system connects resources
at the EGI, OSG, SDSC’s Comet, and the campus HPC resources for distributed
computing. The previous success in the XENON1T computing scheme is also the
starting point for its successor experiment XENONnT, which starts to take data
in autumn 2019.
