Description

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.
