Deploying and (re-)using Virtualized Research Environments in High-Performance and High-Throughput Computing Bauer, Jonathan; Suchodoletz, Dirk von; Vollmer, Jeannette; Rasche, Helena The Virtual Open Science Collaboration Environment project worked on different use cases to evaluate the necessary steps for virtualization or containerization especially when considering the external dependencies of digital workflows. Virtualized Research Environments (VRE) can both help to broaden the user base of an HPC cluster like NEMO and offer new forms of packaging scientific workflows as well as managing software stacks. The eResearch initiative on VREs sponsored by the state of Baden-Württemberg provided the necessary framework for both the researchers of various disciplines as well as the providers of (large-scale) compute infrastructures to define future operational models of HPC clusters and scientific clouds. In daily operations, VREs running on virtualization or containerization technologies such as OpenStack or Singularity help to disentangle the responsibilities regarding the software stacks needed to fulfill a certain task. Nevertheless, the reproduction of VREs as well as the provisioning of research data to be computed and stored afterward creates a couple of challenges which need to be solved beyond the traditional scientific computing models. 2019-04-01T00:00:00Z http://hdl.handle.net/10900/87669 A Sorting Hat For Clusters. Dynamic Provisioning of Compute Nodes for Colocated Large Scale Computational Research Infrastructures Bauer, Jonathan; Messner, Manuel; Janczyk, Michael; Suchodoletz, Dirk von; Wiebelt, Bernd; Rasche, Helena Current large scale computational research infrastructures are composed of multitudes of compute nodes fitted with similar or identical hardware. For practical purposes, the deployment of the software operating environment to each compute node is done in an automated fashion. If a data centre hosts more than one of these systems – for example cloud and HPC clusters – it is beneficial to use the same provisioning method for all of them. The uniform provisioning approach unifies administration of the various systems and allows flexible dedication and reconfiguration of computational resources. In particular, we will highlight the requirements on the underlying network infrastructure for unified remote boot but segregated service operations. Building upon this, we will present the Boot Selection Service, allowing for the addition, removal or rededication of a node to a given research infrastructure with a simple reconfiguration. 2019-04-01T00:00:00Z http://hdl.handle.net/10900/87668 de.NBI Cloud Storage Tübingen. A federated and georedundant solution for large scientific data Gläßle, Benjamin; Hanussek, Maximilian; Bartusch, Felix; Lutz, Volker; Hahn, Ulrich; Dilling, Werner; Walter, Thomas; Krüger, Jens The »German Network for Bioinformatics Infrastructure«, or in short »de.NBI«, is a national research infrastructure providing bioinformatics services to users in life sciences research, biomedicine and related fields. At five sites across Germany, cloud sites were established to host the bioinformatics services. In Tübingen an extension of the storage capabilites of the cloud was planned, implemented and brought into production. We here report about the motivation, requirements, design decisions and experiences which might serve as inspiration for other large scale storage endeavours in the academic domain. 2019-04-01T00:00:00Z
