CERN is the world’s largest particle physics laboratory and home of the Large Hadron Collider (LHC), the world’s most powerful accelerator providing research facilities for High Energy Physics researchers across the globe. The CERN IT department currently has 230 staff, predominantly engineers, who operate one of Europe’s largest research computer centres distributed across two sites in Switzerland and Hungary and supporting about 17,000 users. The department has developed leading expertise in large scale data centres and longstanding collaborations with industrial and academic partners in the fields of high performance computing, advanced networking, large-scale collaborative tools and is a driver of open access to scientific publications and data. It is a major player in the design, development and deployment of grid, cloud and volunteer computing infrastructures with contribution in all the functional areas of computing, data storage and management, security, identity management and more.

DEEP-EST

CERN provided an extreme big-data application drawn from the High Energy Physics domain that was deployed via DEEP‑EST. It demonstrated the feasibility of an integrated data refresh and reduction center for deploying dynamic improvements in code and calibration for eventual analysis use at the CMS experiment.
