High-Performance Computing (HPC) and other research cluster computing resources provided by universities can be useful as a supplement to the collaboration’s own Grid computing resources for data analysis and production of simulated event samples. In Freiburg, the HPC cluster NEMO has been established as a part of the Baden-Württemberg (BW) HPC infrastructure and can be used by the BW particle physics community. The talk describes the concept and implementation of virtualizing the ATLAS software environment to run both data analysis and production on the NEMO host system. Main challenges include the integration into the NEMO and Tier-3 schedulers in a dynamic, on-demand way, providing access to the local user environment, as well as the automatic generation of a fully functional virtual machine image.
