Welcome

The Worldwide LHC Computing Grid (WLCG) is a global collaboration linking grid infrastructures and computer centres worldwide. This is to distribute, store and analyse the immense amounts of data generated by the Large Hadron Collider (LHC) at CERN on the Franco-Swiss border.

The LHC is the largest scientific instrument on the planet. At full operation intensity, the LHC will produce roughly 15 Petabytes (15 million Gigabytes) of data annually, which thousands of scientists around the world will access and analyse.

The mission of the WLCG is to build and maintain a data storage and analysis infrastructure for the entire high energy physics community that will use the LHC.

Today, the WLCG combines the computing resources of more than 100,000 processors from over 170 sites in 34 countries, producing a massive distributed computing infrastructure that provides more than 8,000 physicists around the world with near real-time access to LHC data, and the power to process it.
