The CC-IN2P3 is a data centre providing computing and storage resources as well as institutional collaborative services. It was first dedicated to academic research in nuclear and particle physics in France, but was rapidly opened to international collaborations and experiments such as those running at Fermilab, BNL, SLAC or CERN. It now provides resources for the four LHC experiments, as a Tier-1 for each of them, as well as for nuclear and astrophysics ones.
The CC-IN2P3 has been involved in CMS since the early nineties (1991), providing some computing and storage resources to CMS, to supply the experiment tests and build its computing model (as a part of the Computing Technical Proposal, written in 1996). It officially joined the collaboration in 2010, being among the very first Tier-1 sites for the experiment and played an important role in setting up the distributed computing now in use. The resources provided by the CC-IN2P3 currently account for about 10% of the total Tier-1 resources provided to CMS.
