The UK National Grid Service Andrew Richards – CCLRC, RAL

History  Pre NGS L2G – Level 2 Grid deployed Easter 2003 –contains members from each of the ten UK e-Science Centres and CCLRC plus Centres of Excellence Requirement for dedicated resources  Rollout of NGS NGS Evaluation and Installation May > December 2003 Pre-Production use Started April 2004 (‘Early Bird Users’) Full Production Started – September 2004 (All Hands Meeting 2004 – Nottingham)

Funding –JISC funded £1.06M Hardware ( ) Oxford, White Rose Grid (Leeds) - Compute Cluster Manchester – Data Cluster E-Science Centre funded 420k for additional Data Cluster –JISC funded £900k staff effort including 2.5SY at CCLRC e-Science Centre The e-Science Centre leads and coordinates the project for the JISC funded clusters

Objectives Build on recent advances in grid technology to offer a stable highly available production quality grid service Interoperability with other grids such as those deployed by the Enabling Grids for e- Science in Europe (EGEE) project and the LHC Computing Grid (LCG) To provide the broad user community with access to large scale resources through the grid interface To meet users’ evolving requirements for a production grid service by working with the user community, through the User Group established by the Core Programme To cooperate effectively with the Engineering Task Force and other teams
