标题： Dynamic Virtualized Deployment of Particle Physics Environments on a High Performance Computing Cluster

摘要： 弗赖堡大学的NEMO高性能计算集群已向ATLAS和CMS实验的研究人员开放。 用户从连接到全球大型强子对撞机计算网格（WLCG）的外部机器访问该集群。 本文描述了如何在虚拟机镜像中提供WLCG的完整软件环境。 NEMO的调度器与外部集群的调度器之间的相互作用通过ROCED服务进行协调。 在NEMO部署了一个云计算基础设施，以协调裸金属和虚拟化作业的同时使用。 通过该设置，以透明、自动化和按需的方式为用户提供资源。 虚拟化环境的性能已针对粒子物理应用进行了评估。 显示英文摘要

摘要： The NEMO High Performance Computing Cluster at the University of Freiburg has been made available to researchers of the ATLAS and CMS experiments. Users access the cluster from external machines connected to the World-wide LHC Computing Grid (WLCG). This paper describes how the full software environment of the WLCG is provided in a virtual machine image. 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.
