ATLAS Global Logical Filename (gLFN)

To be able to address all of the ATLAS files, FAX uses Global Name Space in which each file has an unique signature called gLFN (global Logical File Name). FAX than uses special procedure called N2N (name to name translation) in order to find our what is a PFN ( Physical File Name) for at a given site and gLFN .

Users should always use gLFN . How to obtain gLFN for files belonging to a particular dataset or data container is described here.

One can recognize gLFN's as they start with

/atlas/rucio/...

e.g.

//atlas/rucio/user/hito:user.hito.xrootd.mwt2-1M
