Testing XCache for ATLAS workflows — •Guenter Duckeck, Nikolai Hartmann, and Thomas Maier — Ludwig-Maximilians-Universität München

Caching servers are a promising and lightweight alternative or complement to permanent storage clusters. XCache is a service developed by XRootd team which acts as a proxy cache for remote storage. It is integrated into the ATLAS data management system Rucio and provides transparent access to the globally distributed ATLAS data. We have setup such an XCache server at the LRZ-LMU Tier-2, we tested several ATLAS workflows and will discuss possible use cases.
