Belle II Grid Computing Developments at KIT — •Moritz Bauer, R. Florian von Cube, Torben Ferber, Manuel Giffels, Maximilian Horzela, Günter Quast, and Matthias Schnepf — Karlsruhe Institute of Technology

The Belle II experiment studies B-meson decays with high precision. Therefore, Belle II plans to record 50ab⁻¹. This will result in 50PB of raw data, which has to be reconstructed and analyzed. Furthermore, corresponding simulations have to be produced. To achieve this goal the Belle II collaboration uses several data centers around the world as a Grid, similar to the worldwide LHC Computing Grid.

While LHC experiments usually only analyze data from one data-taking period, Belle II analyses typically use the complete dataset over all periods. The high energy physics computing group at KIT works on several development projects to handle these challenges. In this presentation, we describe the challenges as well as the current development projects. These projects include the transparent integration of opportunistic resources to provide more computing resources and caching to provide additional copies of datasets to improve their accessibility automatically.
