Exactly. This is the software delivery mechanism for the LHC experiments. It’s a read only globally distributed (sort of) POSIX filesystem. We use it in ATLAS to deploy both tagged releases and nightly builds. These can be about 100GB in size each. The releases are used for production jobs across the worldwide grid, while the nightlies are used as development targets for individual developers.
