The Worldwide LHC Computing Grid (WLCG) project is a global collaboration of more than 150 computing centres in nearly 40 countries, linking up national and international grid infrastructures.

The mission of the WLCG project is to provide global computing resources to store, distribute and analyse the ~25 Petabytes (25 million Gigabytes) of data annually generated by the Large Hadron Collider (LHC) at CERN on the Franco-Swiss border.
