Description
Summary:Inherited from the flexible architecture of Xrootd, Xcache allows a wide range of customization through configurations and plugin modules. This paper describes several completed and ongoing R&D efforts of using Xcache in the LHC ATLAS distributed computing environment, in particular, using Xcache with the ATLAS data management system Rucio for easy-to-use and to improve cache hit rate, to replace Squid and improve distribution of large files in CVMFS, to adapt the HPC environment and the data lake model for efficient data distribution and access for the HPCs.
