  1. DataTAG / WP4 meetingCern, 29 January 2002Agenda • start at 10.30 • Project introduction, Olivier Martin • WP4 introduction, Antonia Ghiselli • Security/authorization:interoperability issues, Roberto Cecchini • Relationship with Applications, testbed and EU-US intergrid initiative (task 4.4), Mirco Mazzucato • Discussion on: • WP4 organization: man-power, EU-US testbed sites, DataGrid middleware and applications contacts. • proposal of DataTAG/WP4 to US InterGrid Parners. • End at 13.30 A.Ghiselli, INFN-CNAF

  2. DataTAG – WP4 A.Ghiselli CERN, 29 january 2002 ESA A.Ghiselli, INFN-CNAF

  3. WP4 objective • Interoperability between EU and US Grids services from DataGrid, GriPhyN, PPDG and in collaboration with iVDGL over an EU/US Testbed. A.Ghiselli, INFN-CNAF

  4. iVDGL • International Virtual-Data Grid Laboratory • A place to conduct Data Grid tests at scale • Concrete manifestation of world-wide grid activity • Continuing activity that will drive Grid awareness • Scale of effort • For national, international scale Data Grid tests, operations • Computation & data intensive computing • Who • Initially US-UK-Italy-EU; Japan, Australia • & Russia, China, Pakistan, India, South America? • StarLight and other international networks vital A.Ghiselli, INFN-CNAF U.S. Co-PIs: Avery, Foster, Gardner, Newman, Szalay

  10. WP4 Tasks Assuming the same grid basic services (gram,gsi,gris) between the differen grid projects, the main issues are: • 4.1 resource discovery (INFN/2FTE, PPARC/0.5FTE) • 4.2 security/authorization (INFN/4 FTE(2new), UvA/ 1FTE) • 4.3 interworking of collective services (INFN/5 FTE (3new), PPARC/0.5FTE) on EU-US testbed. • 4.4 test applications (INFN/4-5 FTE(2new), PPARC unfunded, ESA/Esrin unfunded A.Ghiselli, INFN-CNAF

  11. WP4 steps • LHC Applications extend existing use-cases (EDG WP8) to test interoperability of the grid components. • Setup Griphyn and PPDG lab environment in EU and DataGrid lab environment in US to test and analyze their services as different grid domains. • Define few testbed sites and man-power. • Identify concrete grid components that will be the targets of interoperability development efforts. • The previous steps provide input to an architectural schema collecting all the services, their relationships, interfaces and protocols following the Globus layered model. • Produce an assessment of interoperability solutions. • EU-US Integrated grid deployment A.Ghiselli, INFN-CNAF

  13. The objectives of this meeting • To establish working relationship with Datagrid, • Middleware WPs, WP6 and ATF • Applicationswilling to run on the EU-US testbed(sites definition). • Definition of the initial EU work program to discuss with US counterpart (ex. I step: configure EU sites with Griphyn and ppdg software and US sites with DataGrid). • Define US counterpart for DataTAG • To agree on the technical coordination with the EU-US intergrid initiative. A.Ghiselli, INFN-CNAF

  14. DataTAG WP4 meeting outcomes • Agrement on the WP4 workprogram steps (slide11) • relationship with Datagrid, • WPs, and ATF • ApplicationsWP8 • US counterpart for DataTAG: iVDGL • Implement direct contacts between WP4 and iVDGL • To agree on the technical coordination with the EU-US intergrid initiative. A.Ghiselli, INFN-CNAF
