The Tier2 is accessible to all members of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) in CERN, Geneva, Switzerland. Interactive logins to Caltech Tier2 resources must comply with the Caltech computing policies.
All clusters and servers at Caltech Tier2 Center use site-wide grid user mapping service (LCMAPS) to authenticate a grid user and provide access to intended resources based on user’s VO membership. A user with CMS VO membership is automatically mapped to a predefined userid.
