Modelling Distributed Computing Infrastructures for High Energy Physics — •Maximilian Horzela¹, Henri Casanova², Robin Hofsaess¹, Manuel Giffels¹, Artur Gottmann¹, Günter Quast¹, Achim Streit¹, and Frederic Suter³ — ¹Karlsruhe Institute of Technology, Karlsruhe, Germany — ²University of Hawai’i at Manoa, Honolulu, USA — ³Oak Ridge National Laboratory, Oak Ridge, USA

Designing distributed, heterogeneous computing-infrastructures is a challenging task. Since, due to their complexity and size, only a single design candidate can be feasibly deployed, building different prototypes is no option.

We therefore propose to simulate the behaviours of infrastructure candidates based on realistic simulation models as an accessible approach. This ansatz already proved to be successful, utilizing the MONARC simulator for the design of the original structure of the WLCG. In this spirit, a modern tool for simulation of high energy physics workloads executing on distributed computing infrastructures is presented. It is based on the SimGrid/WRENCH simulation framework, allowing to simulate complex infrastructures enhanced with models to simulate relevant data access and caching patterns.
