The NES provided compute and data resources accessed through a standard common set of services. NES services are based on the Globus Toolkit for job submission and the Storage Resource Broker for data management. NES resources hosted scientific software packages, including SIESTA and Gaussian. As well as providing access to compute and data resources, the NES offered training and Grid support to all UK academics and researchers in grid computing. NES had more than 500 users and twenty nine sites. The NES and GridPP were the two organisations that made up the the organisation which was the UK's point of contact with the European Grid Infrastructure. Prior to the NES, the UK e-Science programme funded a Grid Support Centre and later the Grid Operations Support Centre. These provided support for end users to use and develop grid computing. Following the UK Engineering Task Force developing the so-called 'Level 2 Grid', which was an ad hoc collection of individual institutes committing a variety of compute resources for grid computing, the NES was funded to develop this into a full service. Initially called the ETFp Grid, or Engineering Task Force Production Grid, it became known as the National Grid Service. Hardware was purchased and installed by February 2004, and a web site appeared by April 2004. During phase 1, from October 2004 to September 2006, it worked with the separately funded Grid Operations Support Centre. By the start of phase two in October 2006, the NGS and the GOSC merged under the single project name NES. The NES had a third phase which ran through September 2011.
Services
The NES provided free-to-use services to UK academic researchers:
Another portal, based on P-GRADE Portal technology, for creation, execution and monitoring of sequential and parallel jobs.
Partner Sites
The NES had the following partner sites:
Cardiff University
University of Glasgow Computing Service
University of Glasgow ScotGrid
Lancaster University
University of Manchester
University of Oxford
Queen's University Belfast
Rutherford Appleton Laboratory
University of Westminster
White Rose Grid
Affiliate Sites
Affiliate sites provided resources to the NES but with more conditions. Sometimes they provide access to their own users through the common NGS interfaces. Members of the GridPP collaboration also offered resources.
All academics in the UK could apply for a free account on the NES. The science and research ranged from the permeation of drugs through a membrane to the welfare of ethnic minority groups in the United Kingdom. Other applications included modelling the coastal oceans, modelling of HIV mutations, research into cameras for imaging patients during cancer treatments and simulating galaxy formation. As an example use of NES, "The motivation, methodology and implementation of an e-Social Science pilot demonstrator project entitled: . This used the NES to investigate a policy relevant social science issue: the welfare of ethnic minority groups in the United Kingdom. The underlying problem is that of a statistical analysis that uses quantitative data from more than one source. The application of grid technology to this problem allows one to integrate elements of the required empirical modelling process: data extraction, data transfer, statistical computation and results presentation, in a manner that is transparent to a casual user". Examples of research using the NES were published in 2006 through 2011.
