  1. The DataTAG Project 25 March, Brussels FP6 Information Day http://www.datatag.org Peter Clarke, University College London

  2. DataTAG Mission TransAtlantic Grid • EU  US Grid network research • High Performance Transport protocols • Inter-domain QoS • Advance bandwidth reservation • EU  US Grid Interoperability • Sister project to DataGRID DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  3. Collaborations • Collaboration with Networks • DANTE and National Research Networks (NRN) • GARR (IT), MB-NG (UK), Surfnet (NL), VTHD (FR) • Internet2/Abilene, Starlight, TeraGrid, ESnet, Canarie • Collaboration with projects in Europe • DataGrid/CrossGrid • Gridstart • National Grid projects (e.g. IT) • LHC Computing Grid (LCG) • Collaboration with projects in the US • Globus • iVDGL • GriPhyN • PPDG DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  8. Phase I (iGRID2002) DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  9. Intel 10GigE Data Transfer Trial On February 27-28, a Terabyte of data was transferred by S. Ravot of Caltech between the Level3 PoP in Sunnyvale near SLAC and CERN through the TeraGrid router at StarLight from memory to memoryas a single TCP/IP stream with 9KB Jumbo frames at a rate of 2.38 Gbps for 3700 seconds.This beat the former record by a factor of approximately 2.5, and used the US-CERN link at 96% efficiency. This is equivalent to: Transferring a full CD in 2.3 seconds (i.e. 1565 CDs/hour)Transferring 200 full length DVD movies in one hour (i.e. 1 DVD in 18 seconds) European Commission DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  10. Objectives EU  US Grid Interoperability • Enable Middleware interoperability between European and US Grid domains • Demonstrate Large Hadron Collider (LHC) Applications running on heterogeneous Grid Issues • Resource Discovery • Authentication & Authorisation • Job scheduling • Data Management DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  11. Results • Common Resource Information Publication • DataGrid Resource Broker and common Information system integration • Implementation in standard Globus release • To be included in next DataGrid Release • Already included in US VDT release and CERN LCG-0 release • Input to GGF and CIM DataTAG - EU FP6 Information Day - Brussels 25 March 2003

  12. Results • Common Virtual Organization Authorization system (VOMS) • jointly developed by DataTAG/DataGRID • Mapping between PKI-based Grid security and Kerberos-based mechanism at the local site. • New Grid monitoring system DataTAG - EU FP6 Information Day - Brussels 25 March 2003
