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.

Working with the European Union

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

See EU-Funded IT projects for more information.

Other IT Projects

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


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. 


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.
