29/1/2002A.Ghiselli, INFN-CNAF10 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

29/1/2002A.Ghiselli, INFN-CNAF11 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

29/1/2002A.Ghiselli, INFN-CNAF13 The objectives of this meeting  To establish working relationship with Datagrid, Middleware WPs, WP6 and ATF Applications willing 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.
