CERN has been running an OpenStack based private cloud infrastructure in production since 2013. This presentation will give a status update of the deployment, and then dive into specific topics, such as the 12-month work to replace the network control plane for 4400 virtual machines or the live-migration machinery used for interventions or reboot campaigns.
The CERN Cloud Infrastructure service has recently commissioned a set of ARM and GPU nodes as hypervisors. This presentation will cover all the steps required to prepare the provisioning of ARM based VMs: the creation of multi-arch docker images for our GitLab pipelines, the preparation of ARM user images, or adaptions to the PXE and Ironic setup to manage this additional architecture. There...
The Helmholtz Association's federated IT platform HIFIS enables the individual Helmholtz centres to share IT services and resources for the benefit of all users in the association. For that purpose a central service catalog - the Helmholtz cloud portal - lists all these services so that scientists, technicians and administrators can make use of them. In this context, DESY offers access to a...
Historically the release processes for supported CERN Linux distributions involved tedious manual procedures that were often prone to human error. In addition, and as a knock-on effect from the turmoil created in 2020 with the CentOS Linux 8 end-of-life announcement; the CERN Linux team have now been required to support an increasing number of Linux distributions.
To cope with this additional...
This presentation will be a follow-up to the presentation and “Linux Strategy” BoF in Umea and summarise the latest evolution on the strategy for Linux at CERN (and WLCG): a recap of the situation (e.g. the issues with Stream or the changes for the RHEL license), a presentation of the agreed strategy as well as insights into the decision making process (in particular for the choice of...
The Swiss National Supercomputing Centre (CSCS), in close collaboration with the Swiss Institute for Particle Physics (CHiPP), provides the Worldwide LHC Computing Grid (WLCG) project with cutting-edge HPC and HTC resources. These are reachable through a number of Computing Elements (CEs) that, along with a Storage Element (SE), characterise CSCS as a Tier-2 Grid site. The current flagship...
We will provide an update on the SLATE project (https://slateci.io), an NSF funded effort to securely enable service orchestration in Science DMZ (edge) networks across institutions. The Kubernetes-based SLATE service provides a step towards a federated operations model, allowing innovation of distributed platforms, while reducing operational effort at resource providing sites. The SLATE...
