Belle II Grid Computing Developments in Germany — •Matthias Schnepf1, Moritz Bauer1, Günter Duckeck2, Torben Ferber1, Oliver Freyermuth3, Andreas Gellrich4, Manuel Giffels1, Günter Quast1, Michel Hernandez Villanueva4, and Peter Wienemann3 — 1Karlsruhe Institute of Technology (KIT) — 2LMU Munich — 3Univertity of Bonn — 4DESY Hamburg
The Belle II experiment studies B-meson decays with high precision and plans to record 50ab−1, which corresponds to 50PB of recorded data. For reconstruction, simulation, and analysis, the Belle II collaboration uses several data centers around the world as a Grid, similar to the worldwide LHC Computing Grid.
To improve the global job throughput and support the local groups, several developments in Belle II Grid computing are being worked on and are applied in Germany or by German groups. In this presentation, we describe the challenges and the current development projects. These involve the Grid storage for local groups, caching techniques to increase dataset accessibility, GPU, and multicore support in the Grid for Belle II.
