DESCRIPTION:Speakers: Dr. BOURILKOV\, Dimitri (University of Florida (US))
 \nThis paper reports the design and implementation of a secure\, wide area
  network\, distributed filesystem by the ExTENCI project\, based on the Lu
 stre filesystem. The system is used for remote access to analysis data fro
 m the CMS experiment at the Large Hadron Collider\, and from the Lattice Q
 uantum ChromoDynamics (LQCD) project. Security is provided by Kerberos aut
 hentication and authorization with additional fine grained control based o
 n Lustre ACLs (Access Control List) and quotas. We investigate the impact 
 of using various Kerberos security flavors on the I/O rates of CMS applica
 tions on client nodes reading and writing data to the Lustre filesystem\, 
 and on LQCD benchmarks. The clients can be real or virtual nodes. We are i
 nvestigating additional options for user authentication based on user cert
 ificates. We compare the Lustre performance to those obtained with other d
 istributed storage technologies.\n\nhttp://indico.cern.ch/contributionDisp
