Distributed simulation of extensive air showers with Geant4 — Kai-Thomas Brinkmann, Hans-Georg Zaunick, and •Daniel Treffenstädt — Justus-Liebig-Universität Gießen

This talk presents an approach to simulating extensive air showers caused by ultra high energy cosmic radiation in earths atmosphere with Geant4. The scope is to simulate the interaction of extensive air showers with an array of plastic scintillator detectors distributed in a loose formation within an area of few square kilometers. The main area of interest thereby is to determine the signature of a shower event specific to the timing of individual detecor events with respect to each other. This simulation however requires a high level of precision and tracking of all individual particles produced in the shower, which causes a high CPU runtime impact. An approach to reduce the total runtime of each simulation by distributing the simulation on a large number of calculation nodes is investigated.
