Data challenges
Data Challenges

  • SC1: initial tests between some Tier-1 sites and CERN. Datafiles transported from disk to disk using globus_url_copy. Date: December 2004. Result: tests were done with BNL, CCIN2P3, Fermilab, FZK and SARA.

  • SC2: sustained file transfers with an aggregated rate of 500 MByte/sec out of CERN. Disk to disk using software components from the radiant service at CERN. Participating sites: CCIN2P3, CNAF, Fermilab, FZK, RAL, SARA. Date: last two weeks of March 2005.

  • SC3: sustained file transfer simultaneously to 6 Tier-1 sites. Disk to tape (at 60 MByte/sec) using SRM. Participating sites: CCIN2P3, CNAF, Fermilab, FZK, RAL, SARA. Date: July 2005.

Data Challenges

  • SC4: sustained file transfer simultaneously to all 10 Tier-1 and some Tier-2 sites. Inclusion of data processing on farms at CERN and at the Tier-1 sites. Date: Q4 2005

  • SC5: the whole infrastructure of Tier-1 and Tier-2 sites in place. Simulated data movements between all partners. Date: Q1 2006

  • SC6: test of the whole infrastructure at twice the nominal rate. Date: Q2 2006

  • SC7: test of the whole infrastructure with real (cosmic) data from the experiments

Tier 2 Light Path Plans

  • U Texas

    • No

  • U Chicago

    • Initially not, though we do have capabilities to do so. At UC, we connect to Starlight via optical links provided by I-WIRE.

  • Indiana U.

    • Initially not, though we do have capabilities to do so.

  • Caltech

    • We'll experiment on-demand network path setup dynamically using Monalisa service agents and GMPLS.

  • U Michigan

    • We are an UltraLight collaborating site and will utilize dedicated light-paths, QoS/MPLS and high-performance protocols (like FAST) to do our Service Challenge work.
