This shows the National Centre, 8 regional centres and 2 laboratories in blue That is the original set up at the start of UK e-Science August 2001 NeSC is jointly run by Edinburgh & Glasgow Universities In 2003 several smaller centres were added (vermilion) (1 st call out) The e-Science Institute is run by the National e-Science Centre. It runs a programme of events and hosts visiting international researchers. It was established in 2001. The Open Middleware Infrastructure Institute was established in 2004, to provide support and direction for Grid middleware developed in the UK. It is based at the University of Southampton. The Grid Operations Centre will be established in 2004. (2 nd call out) The Digital Curation Centre was established in 2004 by the Universities of Edinburgh and Glasgow, the UK Online Library Network at the University of Bath, and the Central Laboratories at Daresbury and Rutherford. It’s job is to provide advice on curating scientific data and on preserving digital media, formats, and access software. (3 rd call out) Edinburgh is one of the 4 founders of the Globus Alliance (Sept 2003) which will take responsibility for the future of the Globus Toolkit. The other founders are: Chicago University (Argonne National Lab), University of Southern California, Los Angeles (Information Sciences Institute) and the PDC, Stockholm, Sweden (4 th call out) The EU EGEE project (Enabling Grids for E-Science in Europe) is establishing a common framework for Grids in Europe. The UK e-Science programme has several connections with EGEE. NeSC leads the training component for the whole of Europe.
