ROOT multiple event (AOD, is the most common NTUP) files from software stack used to selected data sets and analyze compact data use physicist formats generated on generated C++ code to distributed computing calculate new resources. Data quantities such as transfer is done using implied mass of an ATLAS and CMS DDM unstable (new) particle tools, which mostly rely on gridFTP middleware. XROOTD based direct data access is also gaining importance wherever high network bandwidth is available.
