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..

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 (JRA3)
• 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
• JRA1 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)

Next future activities

• Next future activities of the IT-CZ cluster to be
  planned in the first IT-CZ cluster meeting next
  week (Milan, March 24-25, 2004)
• Finalization and deployment (in the INFN-GRID) of
  newer version of Workload Management System
  software (DAG support)
• Demostrated at the last EDG review
• Improvements of the existing WMS
• E.g. support of pull model, handling of
  no-matching requests
• Definition and setting up of new procedures for
  development and testing
• Code reviewed by different people
• Testing procedures
• Useful also to train new people
• Towards a Service Oriented Architecture
• OGSA and web services related activities already
  started
• Issue ARDA
• Relationships between EGEE and ARDA not
  completely clear yet
