Welcome

The Large Hadron Collider at CERN near Geneva is the largest scientific instrument on the planet. When it begins operations, it 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 Worldwide LHC Computing Grid (WLCG) project 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 Worldwide LHC Computing Grid (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.
