EGEE JRA 1 Massimo Sgaravatto INFN Padova Objectives

EGEE JRA 1 Massimo Sgaravatto INFN Padova

Objectives of the activity • Provide robust, supportable middleware components, which must be use in a production Grid Select, re-engineer, in case implement, and integrate identified Grid Services • Multiple platforms • • Evolve towards new standards currently being defined • Services Oriented Architecture • OGSI standards now sort of obsolete given the WSRF announcement on January 20, 2004. • Based on requirements of The applications (Bio & HEP) • The operations • • E. g. deployment, updates, packaging, etc. .

Partners Issue: American involvement still being clarified

Organization • Implementation clusters Responsible for the re-engineering/development of the middleware • Clusters: • • IT-CZ cluster (INFN, Datamat, CESNET) – Workload management, resource access, grid accounting • UK cluster – Information Services • Cern cluster – Data management • Northern Europe cluster – Security (JRA 3) • Integration and Testing group Integration and testing of the software generated by the Implementation group • Delivery of software to Operations • Based at Cern •

Management • Engineering Management Team (EMT) responsible for managing the middleware engineering process • Composed by: JRA 1 leader (F. Hemmer, Cern) • Chief architect (? ) • Manager of the implementation group (E. Laure, Cern) • Leaders of the implementation clusters • • • F. Prelz (IT-CZ) S. Fisher (UK) P. Kunszt (Cern) F. Hedman (NEC) Manager of integration and testing group (M. Barroso Lopez, Cern) • Quality person •
