Ongoing development of the ALICE Tier 2 Center at GSI — •Sören Fleischer, Raffaele Grosso, Jan Knedlik, Thorsten Kollegger, Paul Kramp, and Kilian Schwarz for the ALICE collaboration — GSI, Planckstr. 1, 64291 Darmstadt

GSI has been operating a Tier 2 Center for the ALICE experiment since 2004. It runs on the shared computing cluster in the Green IT Cube at GSI. In 2017 it has been the largest and one of the most efficient ALICE Tier 2 Centers. In this contribution we describe the current status of the center and important changes within the past year. Those include the development of an XRootD plugin which allows local grid clients direct access to a shared file system avoiding XRootD data servers, as well as a plugin that creates symbolic links in order to simplify local data access without grid methods. Medium-term the ALICE Tier 2 Center at GSI will be transformed into one of presumably 3 ALICE Analysis Facilties. The anticipated changes thereby arising are presented.
