The IT-CD group operates, maintains and supports the scientific computing services needed by the laboratory and its experiments, including the Worldwide LHC Computing Grid. The group runs end-users desktop and mobile services and supports the Windows, macOS and Linux operating systems as well as operating systems of mobile phones (iOS and Android). The group also licenses, deploys and configure core productivity applications for Windows and macOS including Microsoft Office across CERN. Finally the group provides interactive terminal services for both window and Linux users together with batch farms for physics analysis.

Compute and Configuration (IT-CD-CC)

Section Leader: Ben Dylan Jones

Provide a first-class set of scientific computing services to deliver the diverse development and large-scale compute requirements of the Organisation and the Worldwide LHC Computing Grid. Provide efficient service configuration and operational support tools to ensure the Organisation’s IT services can meet the coming challenges at the LHC scale.

Cloud and Linux Infrastructure (IT-CD-CLI)

Section Leader: Alejandro Iribarren

Via cloud interfaces, IT-CD-CLI provides, operates, maintains and supports dynamic and efficient provisioning of virtual and physical compute resources for users, groups, departments and the experiments. The section equally provides support for the deployment and operation of CentOS and RedHat Linux on servers and managed desktops, including the development and customization of standard distributions.

Device Provisioning and Productivity (IT-CD-DPP)

Section Leader: Michal Kwiatek

IT-CD-DPP supports Windows and macOS users, manages over 10000 Windows devices and provides Windows and macOS expertise, application deployment and configuration management tools for local administrators across CERN, as well as core productivity applications for Windows and macOS including Microsoft Office and antivirus. We also provide Windows terminal services and the underlying server infrastructure for device management and core applications. We aspire to facilitate coherent use of core applications from any device and to gradually expand iOS and Android support.

Platforms Infrastructure (IT-CD-PI)

Section Leader : Ricardo Rocha

The Platforms Infrastructure section is responsible for developing, operating and evolving cloud native and machine learning platforms for the campus and scientific communities of the organization. In particular, the section provides:

• A centralized Kubernetes service as well as an OCI artifact registry and related ecosystem tools as a cloud native platform
• Machine learning platforms, supporting large scale distributed training, inference and management of models
