Grid Computing at Belle II — •Tobias Jenegger and Thomas Kuhr — Ludwig-Maximilians-Universität München

Over the last decades not just the setup of physics experiments and the measurement instruments have become considerably more sophisticated and complex but also the amount of retrieved data has exceeded what humans can interpret directly. The data can only be handled using large computing systems.

Belle II, a particle physics experiment in Japan designed to study the properties of B mesons, involves over 100 institutes in 25 countries and employs a large grid computing system that allows about 800 scientists to analyse the obtained data and to produce data sets of simulated events. Instead of working with one supercomputer a distributed grid computing system equipped with the most current software technology allows to exploit the computing resources of the individual research institutes in the most efficient way.

This talk will give an overview of the grid computing model at Belle II and present work in progress on developments of an improved user interface.
