SUMMARY:Transparent Global File System Access in Environments with Multipl
 e Authentication Domains
DESCRIPTION:J.D. Maloney (University of Illinois Urbana-Champaign) and Sea
 n Stevens (University of Illinois at Urbana-Champaign)\n\nGlobal file syst
 ems, whose access spans multiple systems/sub-systems within a High-Perform
 ance Computing (HPC) center, are common at many institutions due to a rang
 e of benefits they provide. In the vast majority of cases however, they op
 erate under a single authentication domain or in more complex cases, suppo
 rt multiple domains with each getting siloed data access. Recently at the 
 National Center for Supercomputing Applications (NCSA), we have integrated
  a cluster that pushed us to engineer a solution that provides users the a
 bility to seamlessly access their data, regardless of which authentication
  domain the system is tied to. <br>This paper describes the design, techno
 logies, and processes NCSA architected to deliver this capability to resea
 rchers and shares the suggested practices we’ve discovered while operating
  it. Additionally, we lay out the benefits researchers gained by us provid
 ing this level of integration between the different authentication domains
  at the global file system layer.\n\nRecording: Livestreamed, Recorded\n\n
