Collaborating Partners are those people and institutions that are currently using the LHC Computing Grid or providing a computational resource to it. The Worldwide LHC Grid project consists of three types of partners ("tiers") and 33 countries are formally involved:

Tier-0 is one site: the CERN Computing Centre. All data passes through this central hub but it provides less than 20% of the total compute capacity.

Tier-1 comprises eleven sites, located in Canada, France, Germany, Italy, the Netherlands, the Nordic countries, Spain, Taipei, the UK, and two sites in the USA.

Tier-2 comprises over 140 sites, grouped into 60 federations covering Australia, Austria, Belgium, Canada, China, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Italy, India, Israel, Japan, Republic of Korea, the Netherlands, Norway, Pakistan, Poland, Portugal, Romania, Russia, Slovenia, Spain, Sweden, Switzerland, Taipei, Turkey, the U.K, Ukraine, and the U.S. Tier-2 sites will provide around 50% of the capacity needed to process the LHC data.
