The importance of computing at CERN contibues to grow through various collaborations. The IT Department is involved in a range of technically challenging projects, committed to innovation and development in large scale distributed computing, networking, large scale data management and storage, and industry collaboration.

CERN Initiatives

Worldwide LHC Computing Grid (WLCG)
Our flagship project, a global collaboration linking grid infrastructures and computer centres worldwide. WLCG distributes, stores and analyses the immense amounts of data generated by the LHC.


CERN openlab is a collaboration between CERN and industrial partners to develop new knowledge in Information and Communication Technologies through the evaluation of advanced solutions and joint research to be used by the worldwide community of scientists working at the LHC.

Externally-funded projects

The IT Department is involved in extensive development in grid computing, networking, storage and industry collaboration.

European Commission

See the IT Dept's Horizon2020 projects for more information.


Other IT Projects

CERN's IT department is heavily involved in other infrastructure-building projects on a global scale.



The OpenAIRE project, in the vanguard of the open access and open data movements in Europe was commissioned by the EC to support their nascent Open Data policy by providing a catch-all repository for EC funded research. CERN, an OpenAIRE partner and pioneer in open source, open access and open data, provided this capability and Zenodo was launched in May 2013.


CERN Open Data Portal
The CERN Open Data portal is the access point to a growing range of data produced through the research performed at CERN. It disseminates the preserved output from various research activities, including accompanying software and documentation which is needed to understand and analyze the data being shared.


Data Preservation in High Energy Physics (DPHEP)
This is a collaboration of several major institutes, supporting data preservation and long term analysis in High Energy Physics. 

CERN IT Rapid e-learning
This project aims at promoting features, tools and, mostly IT, services via very short videos - ideally not exceeding 5 minutes. These short informative and educational sequences can be recorded by the CERN audiovisual services and/or screen capture tools at the desk. Our aim is to provide tools and advice for content owners and/or users of the information to do this.



LHC @ Home is a volunteer computing platform where you donate idle time on your computer to help physicists compare theory with experiment, in the search for new fundamental particles and answers to questions about the Universe. 


UNOSAT Creating satellite-derived maps in support of international humanitarian relief effort.
Citizen CyberScience Providing individuals and institutions in the developing world with an appropriate low-cost technology for operational service platforms directed at pressing humanitarian challenges.

Networking for LHC

LHCOPN Large Hadron Collider Optical Private Network
LHCONE LHC Open Network Environment
IndiaLink Dedicated link from India to CERN at 1 gigabit/s for LHC
ESnet High speed TransAtlantic network between CERN and the USA, for the LHC community.
