  1. Grid Prototype • What is it? • The deployment of Grid tools “in production” • A testbed for development + integration • Stage 1 of the ramp-up to LHCUK computing • A facility for running experiments to use • An approach for harnessing existing resources • A means of coordination • For “users”, the visible face of The Grid • …a very tall order! Dave Newbold, University of Bristol 24/5/2001

  2. Grid Prototype • What is it not? • Specific to HEP (necessarily) • A support service (Andy McNab’s problem!) • Completely within the UK • A direct mapping with DataGrid WP6 • …or GridPP WG-G (some mixing with H) • As well understood as some other areas… yet. Dave Newbold, University of Bristol 24/5/2001

  3. Areas of Activity • Running the basic (minimal) Grid services • Information service • Security / CA • Monitoring (fabric; network; performance) • The central testbed site (RAL) • A ‘production’ service, based on the best stable tools • “The Men at Coventry” • Proto regional centre operations • ProtoT1 (RAL); a large manpower requirement • ProtoT2: not directly funded? • ProtoT3: close links with institute system managers Dave Newbold, University of Bristol 24/5/2001

  4. Areas of Activity • Development + integration support • The ‘testbed’ side of things • Providing a stable platform for tests of • Scaling • Interoperability • Regression tests • Partitioned from the production service • Need to be flexible in resource allocation and scheduling • A contribution to the DataGrid WP6 • Data challenge support • Stress-testing the Grid Prototype • May require intensive support + scheduling • Coordinate with WP6/8 Dave Newbold, University of Bristol 24/5/2001

  5. Relationship to other WGs • WGs ABC (middleware): • Supply tools, expertise, policy for GP • Require testbed facilities, monitoring information, feedback • WGs DEF (security, networking): • The enabling services for the GP • Very close communication required • May require testbed facilities • WG H (support): • Provides support to GP ops, developers, users • Critical for the success of the project • WG I (Experiments): • Oversees experiment-specific development • Activities in support of generic HEP apps are overseen by GP.
