US ATLAS Distributed Computing Workshop at the University of Arizona

11 Dec 2013, 08:30 → 12 Dec 2013, 13:30 America/Phoenix

Santa Rita Room (University of Arizona Student Union)

Erich Ward Varnes (University of Arizona (US)), Jason Nielsen (University of California,Santa Cruz (US)), Mark Neubauer (Univ. Illinois at Urbana-Champaign (US)), Michael Ernst (Unknown), Robert W. Gardner (University of Chicago), Shawn McKee (University of Michigan ATLAS Group)

The US ATLAS workshop on distributed computing will held at the University of Arizona in Tuscon on December 11-12, 2013.  There will be a number of topics of interest relating to use of dedicated US ATLAS computing resources and approaches for leveraging campus compute resources for ATLAS analysis. A preliminary list is as follows:

• Introduction to the US ATLAS Distributed Computing Facility
• Overview of the Analysis Support group activities supporting distributed computing in US ATLAS
• Strategies for access and management of dedicated US ATLAS computing resources 
• Usability of the Federated ATLAS Xrootd system (FAX) and wide area network-based data access
• Tier3 Task Force Implementation 
• Support for maintaining and upgrading Tier3 clusters
• Networking performance monitoring (perfSONAR-PS) and connectivity issues (campus networks, science DMZs, LHC network peering)
• Planned US ATLAS Computing Facility projects
  • Virtual extensions to Tier3 clusters via job “flocking" into US ATLAS Tier2 centers
  • FAXbox - an integrated storage service for analysis computation
  • AtlasConnect - a service for high throughput analysis submission which uses Tier2s, campus grids, and Tier3 clusters
  • CI Connect - an approach for leveraging compute resources at your institution

The meeting will be hosted by the High Energy Physics group at the University of Arizona.
