The Worldwide LHC Computing Grid (WLCG), formerly (until 2006)[1] the LHC Computing Grid (LCG), is an international collaborative project that consists of a grid-based computer network infrastructure incorporating over 170 computing centers in 42 countries, as of 2017[update]. It was designed by CERN to handle the prodigious volume of data produced by Large Hadron Collider (LHC) experiments.[2][3]

By 2012, data from over 300 trillion (3×1014) LHC proton-proton collisions had been analyzed,[4] and LHC collision data was being produced at approximately 25 petabytes per year. As of 2017[update] the LHC Computing Grid is the world's largest computing grid comprising over 170 computing facilities in a worldwide network across 42 countries[4][5][6] scattered around the world that produce a massive distributed computing infrastructure with about 1,000,000 CPU cores, providing more than 10,000 physicists around the world with near real-time access to the LHC data, and the power to process it.

^Worldwide LHC Computing Grid about page 2017: "Even after filtering out 99% of it, in 2017 we're expecting to gather around 50 petabytes of data. That's 50 million gigabytes, the equivalent to nearly 15 million high-definition (HD) movies."
^Worldwide LHC Computing Grid main page 2017: "WLCG is the world's largest computing grid. It is supported by many associated national and international grids across the world, such as European Grid Initiative (Europe-based) and Open Science Grid (US-based), as well as many other regional grids."
