摘要：

A setup for dynamically providing resources of an external, non-dedicated cluster to researchers of the ATLAS and CMS experiments in the WLCG environment is described as it has been realized at the NEMO High Performance Computing cluster at the University of Freiburg. Techniques to provide the full WLCG software environment in a virtual machine image are described. The interplay between the schedulers for NEMO and for the external clusters is coordinated through the ROCED service. A cloud computing infrastructure is deployed at NEMO to orchestrate the simultaneous usage by bare metal and virtualized jobs. Through the setup, resources are provided to users in a transparent, automatized, and on-demand way. The performance of the virtualized environment has been evaluated for particle physics applications. © 2019, Springer Nature Switzerland AG.
